INSTALLATION AND REPAIR SHOULD BE DONE BY A QUALIFIED SERVICE PERSON. THE APPLIANCE  
SHOULD BE INSPECTED BEFORE USE AND AT LEAST ANNUALLY BY A QUALIFIED SERVICE PERSON.  
MORE FREQUENT CLEANING MAY BE REQUIRED DUE TO EXCESSIVE LINT FROM CARPETING, BED-  
DING MATERIAL, ETC. IT IS IMPERATIVE THAT CONTROL COMPARTMENTS, BURNERS AND CIRCU-  
LATING AIR PASSAGEWAYS OF THE APPLIANCE BE KEPT CLEAN.  
DUE TO HIGH TEMPERATURES, THE APPLIANCE SHOULD BE LOCATED OUT OF TRAFFIC AND AWAY  
FROM FURNITURE AND DRAPERIES.  
WARNING!  
THIS APPLIANCE MAY ONLY USE THE DIRECT VENT CHIMNEY SYSTEM DESIGNED FOR USE  
WITH THE UNIT AND MUST NOT BE CONNECTED TO A CHIMNEY FLUE SERVICING A SEPA-  
RATE SOLID FUEL OR GAS FUEL BURNING APPLIANCE.  
A. GAS PRESSURE  
For natural gas, the minimum inlet gas supply pressure is  
4.5 inches water column, and the maximum inlet gas pres-  
sure is 7.0 inches water column, for the purpose of input  
C. FIREPLACE LOCATIONS AND  
SPACE REQUIREMENTS  
This appliance may be installed along a wall, across a  
corner or use an exterior chase. The GC150 Series  
may be installed at a height level with the floor, or it  
can be raised up from the floor to enhance its visual  
impact. Figure 1 illustrates a variety of ways the  
appliance may be located in a room. These appli-  
ances are also certified for installation in a bedroom  
or bed/sitting room in the U.S.  
adjustment. Input rate is 22,500 Btu/hr. For propane gas,  
the inlet gas supply pressure must be at least 11.0 inches  
water column and a maximum 14.0 inches water column.  
(See CKP Natural Gas to Propane Gas Conversion Kit  
installation instructions.)  
A 1/8" NPT plugged tapping is provided on the gas control  
valve, near the outlet to the main burner immediately  
upstream of the gas supply connection to the appliance,  
accessible for a test gage connection .  
Optimum manifold pressure is 3.5 inches water column for  
natural gas and 10.5 inches water column for propane gas.  
B. HIGH ALTITUDE INSTALLATION  
For U.S. installation, units are tested and approved for ele-  
vations from 0-2000 feet.  
When installing this unit at an elevation above 2000 feet,  
United States codes require a decrease of the input rating  
by changing the existing burner orifice to a smaller size.  
Input should be reduced 4 percent for each 1000 feet  
above sea level. Check with the local gas utility for proper  
orifice size identification. This unit uses a .093in. /2.36  
mm. orifice size on natural gas versions and a .056 in./1.42  
mm. orifice size on propane gas converted versions.  
Figure 1  
Fireplace Locations and Clearances  
D. CLEARANCES  
Consult your local gas company for assistance in determin-  
ing the proper orifice for your location or refer to ANSI  
Z223.1-latest edition, Appendix F.  
The following clearances to combustibles must be  
maintained: Minimum clearances to the top standoffs  
of the unit - 0", floor - 0", back - 1/2", sides - 1/2", top  
of the hood to ceiling - 30". Minimum clearances to  
venting are as follows: Horizontal runs require a 3"  
minimum air space on the top and a 1" minimum air  
space on the sides and bottom of the vent section.  
Vertical rise sections require a 1" minimum air space  
completely around the vent sections.

E. FRAMING THE FIREPLACE  
Note: If an optional fan (FK4) or hand held remote  
control (RC4 or RC5) are to be used, wiring must  
be done prior to finishing to avoid reconstruction.  
Note: The remote wall switch must be wired prior  
to applying the finishing material in order to avoid  
reconstruction.  
Figure 2a  
Framing the Fireplace  
The GC150 Series Gas Appliance will fit a framed  
opening of 40" w X 1612" d X 3018" h.  
F. FINISHING MATERIALS  
Only non-combustible materials may be used to  
cover the black surfaces of the fireplace front.  
Combustible Finishing Material. Material made of  
or surfaced with wood, compressed paper, plant  
fibers, plastics, or any material capable of igniting  
and burning, whether flame proofed or not, plastered  
or unplastered.  
Non-combustible Finishing Material. Material  
which will not ignite and burn. Such materials are  
those consisting entirely of steel, iron, brick, tile, con-  
crete, slate, glass or plasters, or combination thereof.  
High Temperature Sealant Material. Sealants that  
will withstand high temperatures (300° F+); General  
Electric RTV103 (Black), or equivalent. Rutland, Inc.  
Fireplace Mortar #63, or equivalent.  
After completing the framing and applying the finish-  
ing material (dry wall) over the framing, a non-com-  
bustible sealant, one-half inch wide maximum, must  
be used to close off any gaps at the top and sides  
between the fireplace and facing to prevent cold air  
leaks. See Figure 3.  
Figure 2 - Framing the Fireplace  
Figures 2 and 2a show a typical framing of this fire-  
place assuming combustible materials are used. All  
required clearances to combustibles around the fire-  
place must be adhered to. A 1/2" air clearance must  
be maintained at the back and sides of the firebox  
assembly. A minimum of 38” is required to the bot-  
tom of a 7” mantle. Anything greater than 7” must be  
42” above the base of the unit. Any framing on top of  
the fireplace must be above the top standoffs. Vent  
sections for a horizontal run require a 3" minimum air  
space on top and a 1" minimum air space on the  
sides and bottom. Vertical rise sections require a 1"  
minimum air space completely around the vent sec-  
tions.

V. STEP-BY-STEP INSTALLATION OF  
THE FIREPLACE SYSTEM  
WARNING!  
BEFORE STARTING, DO THE FOLLOWING:  
1. WEAR GLOVES AND SAFETY GLASSES FOR PROTECTION.  
2. KEEP HAND TOOLS IN GOOD CONDITION. SHARPEN CUTTING EDGES AND MAKE SURE TOOL  
HANDLES ARE SECURE.  
3. ALWAYS MAINTAIN THE MINIMUM AIR SPACE REQUIRED TO THE ENCLOSURE TO PREVENT FIRE.  
STEP 1 - Positioning the Firebox  
This fireplace may be placed on a smooth combustible or non-  
combustible continuous, flat surface. When the appliance is  
installed directly on carpeting, tile or other combustible material  
other than wood flooring, the appliance shall be installed on a  
metal or wood panel extending the full width and depth of the appli-  
ance. Slide the unit into position and level the fireplace from side-  
to-side and front-to-back. Shim with non-combustible material,  
such as sheet metal, as necessary.  
Secure the fireplace by bending out the nailing flanges located on  
each side of the fireplace and nailing the unit to the framing. See  
Figure 4.  
A
B
Figure 4  
Nailing Flanges  
STEP 2 - Termination  
Two types of termination are available for this appliance, horizon-  
tal and vertical. For vertical termination, skip section A and  
advance to section B on page 11.  
A. Horizontal Termination  
Minimum combustible clearances to the vent on a horizontal run  
is 3" on top and 1" on the bottom and sides. These clearances  
must be maintained at all times. The maximum horizontal run  
allowed for venting is 26 feet. The maximum vertical rise allowed  
for horizontal termination is 25 feet. See Figure 5.  
1. Assembling vent sections. Attach either a VE12 (starter  
elbow), VE16, VE20 or straight vent section (depending upon  
your specific installation) to the top of the appliance. Secure  
with the three screws supplied. Use only vent supplied and  
listed for use with this appliance and the appropriate number of  
direct vent sections. MAINTAIN MINIMUM CLEARANCES  
OR GREATER AROUND THE VENT SYSTEM. Do not pack  
air spaces with insulation or other material.  
a. Using elbows. The first elbow used with horizontal termi-  
nation must be starter elbow 15942. The maximum horizontal  
distance this vent system may reach is 26'. No more than 3  
elbows may be used. A single vertical-to-horizontal elbow is  
already calculated into the allowable 26' run. Each additional  
elbow reduces the maximum horizontal distance by three feet.  
Example, by using three total elbows, the maximum horizontal  
distance has been reduced to twenty feet (3 - 1 = 2 elbows X 3'  
= 6'; 26' max. - 6' of elbows = 20' of horizontal run).  
Figure 5 - Horizontal Length  
Note: The horizontal run of vent must have a  
1/4" rise for every 1 ft. of run towards the ter-  
mination. Never allow the vent to run down-  
ward. This could cause high temperatures  
and may present the possibility of a fire.

GC150 SERIES DIRECT VENT GAS APPLIANCE  
b. Amount of venting required. Due to the many  
different combinations that can be used when con-  
structing venting, the number of vent sections  
required can only be determined by the installer.  
Note: Horizontal runs will require the use of  
one Vent Support (VS4) for every 3' of vent.  
2. Preparing the wall for interior wall shield. A  
hole measuring 10" wide X 12" high must be cut  
and framed in the exterior wall where venting will  
be terminated. If the wall being penetrated is con-  
structed of non-combustible material, i.e. masonry  
block or concrete, a 9" diameter port is accept-  
able.  
Figure 6  
Exterior Wall Hole  
The hole must be positioned so the vent system  
will have a 1/4" rise for every 12" of run AND be  
perpendicular to the wall. See Figure 6. The  
height of the hole must be located to meet all local  
and national codes and not be easily blocked or  
obstructed. The minimum height to the top of the  
exterior wall hole is 45” from the base of the unit.  
This figure will increase by the length of each verti-  
cally positioned vent section added to the venting  
system.  
3. Interior Wall Shield. An interior wall shield  
must be installed each time the venting system  
penetrates a wall. This shield has been designed  
to maintain the minimum clearances needed for  
the venting system and prevent cold air infiltration.  
Figure 7  
Interior Wall Shield  
After the venting hole has been cut and framed,  
secure an interior wall shield into position with four  
1" fasteners, one in each corner. Bend out the  
tabs located on the inner portion of the wall shield  
and use a 1/2" screw to secure each tab to the  
penetrating pipe. See Figure 7. (1/2" screws are  
used to avoid penetrating the inner pipe.)  
Note: Exterior wall thickness must be a min-  
imum of 4" to a maximum of 2312”.  
4. Venting through the wall. Horizontal venting  
must terminate within the shaded area shown in  
Figure 5 on the previous page. For example, if  
your vertical rise is the minimum one foot, venting  
can terminate anywhere between 16 inches and 3  
feet.  
Figure 8  
Venting Through the Wall  
NOTE: IF THE TERMINATION CAP IS SUR-  
ROUNDED BY VINYL SIDING OR IS LOCAT-  
ED BELOW A VINYL SOFFIT, A VINYL  
SHIELD MUST BE USED TO PREVENT DAM-  
AGE TO THE VINYL.  
The last section of vent may require cutting, depend-  
ing upon wall thickness and appliance location. The  
end of the vent must penetrate the exterior wall. Cut  
the pipe so the outer vent section extends past the  
exterior wall by 1" and the inner vent section extends  
past the exterior wall by 212". See Figure 8.

To install the termination cap, slide the cap vent  
sections into the vent sections as shown in Figures  
10A and 10B. Secure the cap flush to the wall  
using the eight 1" fasteners provided. Seal the cap  
to the wall with a mastic such as silicone caulking.  
Fasten the inner vent with three 1/2" screws to  
secure the vent. (An optional CS cap shield is  
required if the cap is located in an area of easy  
accessibility. See Figure 11.) Vent termination  
must not be recessed into the wall or siding.  
Be sure to follow all termination cap location mini-  
mum dimensions that have been discussed on the  
previous page.  
Figure 10A  
Termination Cap  
Skip section B below and continue with Step 4 on  
page 13.  
B. Vertical Termination  
When planning your fireplace location, the vent sys-  
tem construction and necessary clearances must be  
considered. The following figures are the maximum  
distances from the base of the unit, as well as the  
minimum air space clearances that must be main-  
tained: Maximum straight unsupported rise - 25 feet;  
maximum horizontal unsupported run - 3 feet; air  
space clearances around vertical venting - 1" on all  
sides; air space clearances around horizontal venting  
- 3" on top and 1" on sides and bottom; maximum  
height - 40' from the base of the unit. Every 1' of hori-  
zontal run requires at least 2' of vertical rise.  
(Example: a 12' overall installation height may be off-  
set as much as 6' horizontally.) The maximum is 20  
feet.  
Figure 10B  
Proper Positioning of Termination Cap & Shield  
1. Assembling vent sections. Attach either a  
15942B (starter elbow) or straight vent section  
(depending upon your specific installation) to the  
top of the appliance. Secure with the three screws  
supplied. Use only vent supplied with this appli-  
ance and the appropriate number of direct vent  
sections. MAINTAIN MINIMUM CLEARANCES  
OR GREATER AROUND THE VENT SYSTEM.  
Do not pack air spaces with insulation or other  
material.  
a. Using elbows. To bypass any overhead  
obstructions, the vent system may be offset using  
a 90° elbow (VK5) or a 45° elbow (EL45). Vent  
stabilizers (VS4) have straps for securing these  
parts to joists or rafters. Plumbers tape may be  
purchased locally and used in conjunction with  
vent stabilizers. See Figure12.  
Figure 11

2. Preparing the ceiling for firestop spacers.  
Mark and cut out an opening in the ceiling for the  
firestop spacer. Frame the opening with the same  
size lumber used in the ceiling joists. Unless the  
flue if offset, frame the 10" x 10" opening directly  
over the firebox.  
3. Installing the firestop spacers. Firestop spac-  
ers must be used whenever the venting penetrates  
a ceiling/floor area.  
In all situations, firestop spacers are to be nailed to  
the ceiling joists from the bottom or fireplace side,  
EXCEPT when the space above is an insulated  
ceiling or attic space. In this situation, the firestop  
spacer must be nailed from the top side to prevent  
loose insulation from falling into the required one  
inch air space around the vent system. See Figure  
13.  
Install the firestop spacer (FS6) by positioning and  
nailing the four sides of the firestop spacer to the  
joists using a minimum of three nails per side.  
Figure 13  
4. Securing vent system. Continue assembling  
the vent sections up through the firestop spacers  
as needed. vent sections must be locked into posi-  
tion with the screws provided, using the predrilled  
holes. The 15942B starter elbow and the vent sta-  
bilizers have straps for securing these parts to  
joists or rafters.  
Installing the firestop spacer  
Note: Be sure to provide intermediate sup-  
port for the vent during construction and  
check to be sure inadvertent loading has  
not dislodged the vent from the appliance  
or any vent joint.  
6. Marking the exit point in the roof. Locate  
the point where the venting will exit the roof by  
plumbing down to the center of the vent. Drive a  
nail up through the roof to mark the center. See  
Figure 15.  
7. Cutting out the hole in the roof. Measure to  
either side of the nail and mark the 10" x 10" open-  
ing required. This is measured on the horizontal;  
actual length may be larger depending on the pitch  
of the roof. Cut out and frame the opening. See  
chapter 25 of the Uniform Building Code for Roof  
Framing details. A one inch minimum air space  
clearance must be maintained between the chim-  
ney section and the roof.  
8. Install roof flashing or site-produced chase  
top. Position a roof flashing or a site-produced  
chase top and secure in place with nails.  
9. Assembling vent sections. Continue to add  
vent sections through the roof opening, maintaining  
at least a one inch air space clearance. If a specif-  
ic height is desired, the chimney sections may  
have to be cut (using shears) to a certain length.

10. Termination cap. Major building codes spec-  
ify a minimum venting system height above the  
roof top depending on roof pitch. See Figures 15  
and 16.  
STEP 3 - Double Checking  
When construction of the entire vent system has  
been completed, double check to make sure all  
venting sections and termination caps are unob-  
structed. Exhaust gases are extremely hot.  
When you have chosen a horizontal termination,  
be sure there are no possible future obstructions  
from trees, bushes, snow drifts, etc. A cap shield  
can be purchased to help prevent possible con-  
tact.  
STEP 4- Gas line installation  
Install the gas line piping up to the right side of  
the appliance. A separate shut-off gas valve  
(supplied) should always be used. See Figure 17.

A. STANDING PILOT OPERATION  
Note: Keep the area near the appliance  
clear and free from combustible materials,  
gasoline and other flammable vapors and  
liquids.  
1. Initial and Seasonal Lighting Procedure. Initial  
lighting constitutes the first time the appliance has  
been lit after installation. Seasonal lighting refers to  
lighting the appliance after it has been unused and  
the gas valve has been turned to OFF.  
Be sure the remote wall switch and the gas knob  
(located behind the lower access panel) have been  
turned to the OFF position. See Figure 35. Also,  
your unit may have a rocker ON/OFF switch  
installed inside the lower panel; it if does, this also  
needs to be turned to the OFF position. If they are  
not, do so and allow the appliance to sit for five min-  
utes so any gas that may have accumulated in the  
main burner compartment escapes.  
Turn the manual on/off valve to ON. Turn the gas  
knob to PILOT, as shown in Figure 36, and press in.  
While holding it in, light the pilot by pressing the red  
ignitor button, shown in Figure 37, several times until  
the pilot ignites. Continue to hold in the gas knob for  
about one minute after the pilot is lit. Release the  
gas knob. The pilot should remain lit. If it goes out,  
turn everything to the OFF position, let it sit for five  
minutes and repeat this step again.  
Figure 35  
Standing Pilot Ignition Valve “OFF”  
When the pilot remains lit, turn the gas knob to the  
ON position. See Figure 38. You may now turn the  
remote wall switch to the ON position which will turn  
on the main burner. Initially, the flames may resem-  
ble more of a blue color but after the first 20 minutes  
of operation, they will become more yellow.  
Figure 36  
Standing Pilot Ignition Valve to “PILOT”  
Note: When first operated, this unit may release  
an odor for the first several hours. This is caused  
by the curing of the paint and the burning off of  
any oils remaining from manufacturing.  
2. Seasonal Shutdown. When the burning season  
comes to an end, the entire system should be shut  
down. This way, no gas will be running to the  
appliance while it is not in use.  
To shut down the appliance for a long period of  
time, you must first shut off the main burner by  
moving the remote wall switch (and the ON/OFF  
rocker switch, if applicable) to the OFF position.  
Figure 37

Next step, remove the lower access panel to  
expose the valve area. (Follow Step 1 on page  
18.) Locate the gas knob and turn it to the PILOT  
position. Press in and continue turning to the OFF  
position. Turn the manual ON/OFF valve to OFF.  
Your entire system is now shut down.  
3. Lighting Procedure During Regular Use.  
Simply turn the wall switch to the ON position. This  
will ignite the main burner.  
4. Shutdown During Regular Use. Simply turn  
the remote wall switch to OFF. This will disengage  
the burner and the flames will extinguish. The pilot  
light will continue to burn.

GC150 SERIES DIRECT VENT GAS APPLIANCE  
If you own a standing pilot ignition, skip section B and  
continue with Step 2.  
2. Seasonal Shutdown. When the burning sea-  
son comes to an end, the entire system should be  
shut down. Note: There may be a rocker switch  
on a column in the control area, as well as a  
wall switch. Both have to be off for the unit to  
be off. In this way, no gas will be running to the  
appliance while it is not in use.  
To shut down the appliance for an extended period  
of time, you must first shut off the main burner by  
moving the remote wall switch to the OFF position.  
The next step is to remove the lower access panel  
to expose the valve area. Locate the gas valve  
knob and turn it to the OFF position. Turn the  
manual on/off knob to OFF. Your entire system is  
now shut down.  
3. Lighting Procedure During Regular Use.  
Simply turn the wall switch to the ON position.  
This will activate the ignitor and the main burner  
will light.  
B. ELECTRONIC IGNITION OPERATION  
1. Initial and Seasonal Lighting Procedure.  
Initial lighting constitutes the very first time the  
appliance has been lit after installation. Seasonal  
lighting refers to lighting the unit after it has been  
unused and the gas valve has been turned to OFF.  
Be sure the remote wall switch and the manual  
on/off knob have been turned to the OFF position.  
Also, your unit may have a rocker ON/OFF switch  
installed inside the lower panel; if so this also  
needs to be turned to the OFF position. If they are  
not, do so and allow the appliance to sit for five  
minutes so any gas that may have accumulated in  
the main burner compartment escapes.  
Turn the manual on/off knob inside the lower  
access area to the ON position. Then, turn the  
remote wall switch to ON. This will activate an  
electronic spark. Initially, the flames may have  
more of a blue color but after the first 20 minutes of  
operation, they will become more yellow.  
4. Shutdown During Regular Use. Simply turn  
the remote wall switch to the OFF position. This  
will disengage the ignitor and the main burner will  
extinguish.  
STEP 2 - Replacing the Lower Access Panel.  
To replace the lower grille panel, align the lower  
panel with the [4] Pins ([2] per column.  
See Figure 39. Press the panel in and down to  
secure it in place. See Figure 40.  
Note: When first operated, this unit may  
release an odor for the first several  
hours. This is caused by the curing of  
the paint and the burning off of any oils  
remaining from manufacturing.

VII. MAINTENANCE INSTRUCTIONS  
Cleaning the burner and control compartment  
Keep the burner and control compartment clean by brushing and  
vacuuming at least once a year. Always turn off the gas valve and  
the ON/OFF switch before cleaning.  
Checking flame patterns  
Visually check the flame of the burner periodically, making sure the  
flames are steady; not lifting or floating. The flame color should be  
blue with yellow tips. The ignitor (electronic) or thermopile (stand-  
ing pilot) tips should be covered with flame. See Figures 41  
through 44.  
Venting system inspection  
Figure 41  
Electronic Ignition  
The appliance and venting system should be inspected before use,  
and at least annually, by a qualified field service person, to ensure  
that the flow of combustion and ventilation air is not obstructed.  
Cleaning the glass  
Note: When cleaning the glass, NEVER use abrasive  
materials. NEVER clean glass when hot. Keep pets  
and children a safe distance away.  
It is recommended to wear gloves while handling or removing  
glass. DO NOT REMOVE GLASS WHEN HOT.  
Clean glass after initial one hour burn. This is to remove any film  
that develops from oils and log burn in time. After initial cleaning,  
clean as needed.  
Figure 42  
Electronic Ignition  
To remove the glass for cleaning, follow Step 11 on page 16.  
Handle glass panel with care to avoid striking or scratching it on  
hard objects.  
To clean the glass, use a non-abrasive automotive rubbing com-  
pound and glass cleaner. Simply apply an adequate amount to  
the glass and wipe off per manufacturers instructions. Contact  
your local stove shop or fireplace accessaries store for further rec-  
ommendations.  
Never operate this appliance without the glass properly secured in  
place or if the glass is broken.  
In the event of glass breakage, follow glass removal instructions  
to remove the top retaining strip. Remove lower retaining strip in  
the same manner. This will allow the removal of all glass frag-  
ments and sheet metal edge protection strips. Vacuum all  
remaining glass pieces with a shop vac. (DO NOT VACUUM IF  
PIECES ARE HOT.) Replace glass only with Heatilator part num-  
ber 15573 ordered direct or through your local distributor. Never  
use substitute material. Only fully tempered soda lime safety  
glass or optional ceramic glass may be used on this appliance.  
Figure 43  
Standing Pilot  
Log cleaning  
Logs can be easily lifted out of position. Carbon build-up can be  
removed with a vacuum cleaner.  
To prevent the possibility of soot, we have provided your fireplace  
with an adjustable air shutter. Your air shutter is provided in an  
open position to ensure clean operation under normal situations.  
In the even that soot is accumulating in your appliance, the air  
shutter should be opened farther as shown in Figure 44. This can  
be done with a screwdriver or a 1/4” wrench. Also, ensure logs  
are positioned correctly to minimize flame contact with the logs.
