Note: Where listed vented decorative logs are required, thermostat  
operation is not permitted.  
UNPACKING  
While it is good to make your home energy efficient, your home  
needs to breathe. Fresh air must enter your home. All fuel-burning  
appliances need fresh air for proper combustion and ventilation.  
CAUTION: Do not remove the data plates from the  
grate assembly. The data plates contain important  
warranty and safety information.  
Exhaustfans,fireplaces,clothesdryers,andfuelburningappliances

air for these appliances. This will insure proper venting of vented  
fuel-burning appliances.  
1. Remove logs and heater base assembly from carton. Note: Do  
not pick up heater base assembly by burners. This could dam-  
age heater. Always handle base assembly by grate.  
2. Remove all protective packaging applied to logs and heater  
for shipment.

The following are excerpts from National Fuel Gas Code, ANSI  
Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation.  
All spaces in homes fall into one of the three following ventilation  
classifications:  
1. Unusually Tight Construction  
2. Unconfined Space  
PRODUCT FEATURES  
OPERATION  
3. Confined Space  
This heater is clean burning. It requires no outside venting. There is  
no heat loss out a vent or up a chimney. Heat is generated by both  
realistic flames and glowing coals. This heater is designed for vent-  
free operation with flue damper closed. It has been tested and  
approved to ANSI Z21.11.2 standard for unvented heaters. State and  
local codes in some areas prohibit the use of vent-free heaters. This  
heater may also be operated as a vented decorative (ANSI Z21.60)  
product by opening the flue damper (Non-Thermostat Models Only).  
The information on pages 4 through 6 will help you classify your  
space and provide adequate ventilation.  
Unusually Tight Construction  
The air that leaks around doors and windows may provide enough  
fresh air for combustion and ventilation. However, in buildings of  
unusually tight construction, you must provide additional fresh air.

= _____________ Btu/Hr  
The National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines a  
confined space as a space whose volume is less than 50 cubic feet  
per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating  
of all appliances installed in that space and an unconfined space as  
aspacewhosevolumeisnotlessthan50cubicfeetper1,000Btuper  
hour (4.8 m3 per kw) of the aggregate input rating of all appliances  
installed in that space. Rooms communicating directly with the  
space in which the appliances are installed*, through openings not  
furnished with doors, are considered a part of the unconfined space.  
4. Compare the maximum Btu/Hr the space can support with the actual  
amount of Btu/Hr used.  
__________________ Btu/Hr (maximum the space can support)  
__________________ Btu/Hr (actual amount of Btu/Hr used)  
Example: 51,200 Btu/Hr (maximum the space can support)  
73,000 Btu/Hr (actual amount of Btu/Hr used)  
The space in the above example is a confined space because the actual Btu/  
Hr used is more than the maximum Btu/Hr the space can support. You must  
provide additional fresh air. Your options are as follows:  
* Adjoining rooms are communicating only if there are doorless  
passageways or ventilation grills between them.  
A. Rework worksheet, adding the space of an adjoining room. If the ex-  
tra space provides an unconfined space, remove door to adjoining  
room or add ventilation grills between rooms. See Ventilation Air From  
Inside Building, page 6.

primary heat source. If you have a central heating  
system, you may run systems circulating blower  
while using heater. This will help circulate the heat  
throughoutthehouse. Intheeventofapoweroutage,  
you can use this heater as your primary heat source.  
CAUTION: This heater creates warm air currents.  
These currents move heat to wall surfaces next to  
heater. Installing heater next to vinyl or cloth wall  
coveringsoroperatingheaterwhereimpurities(such  
as, but not limited to, tobacco smoke, aromatic  
candles, cleaning fluids, oil or kerosene lamps, etc.)  
in the air exist, may discolor walls or cause odors.  
IMPORTANT: Vent-free heaters add moisture to the air. Although  
this is beneficial, installing heater in rooms without enough venti-  
lation air may cause mildew to form from too much moisture. See  
Air for Combustion and Ventilation, pages 4 through 6.  
WARNING: A qualified service person must in-  
stall heater. Follow all local codes.  
NOTICE: State or local codes may only allow opera-  
tionofthisapplianceinaventedconfiguration.Check

INSTALLING DAMPER CLAMP ACCESSORY  
FOR VENTED OPERATION  
INSTALLING HEATER BASE ASSEMBLY  
WARNING: You must secure this heater to fire-  
place floor. If not, heater will move when you adjust  
controls. Moving heater may cause a gas leak.  
Note: When used as a vented heater, appliance must be installed  
only in a solid-fuel burning fireplace with a working flue and  
constructed of noncombustible material.  
If your heater is a manually-controlled model, you may use this  
heater as a vented product. There are three reasons for operating  
your heater in the vented mode.  
WARNING:Ifinstallinginasunkenfireplace,special  
care is needed. You must raise the fireplace floor to  
allow access to heater control panel. This will insure  
adequate air flow and guard against sooting and con-  
trolsbeingdamaged.Raisefireplacefloorwithnoncom-  
bustible material. Make sure material is secure.  
1. The fireplace does not meet the clearance to combustibles re-  
quirements for vent-free operation.  
2. State or local codes do not permit vent-free operation.  
3. You prefer vented operation.  
CAUTION: Do not pick up heater base assembly by  
burners. This could damage heater. Only handle base  
assembly by grates.  
If reasons number 1 or 2 above apply to you, you must permanently  
open chimney flue damper. You must install the damper clamp  
accessory(toorder,seeAccessories,page36).Thiswillinsurevented  
operation (see Figure 10). The damper clamp will keep damper open.  
Installation instructions are included with clamp accessory.  
IMPORTANT: Make sure the heater burners are level. If heater is  
not level, heater will not work properly. For thermostat models,  
avoid damage to thermostat bulb. Avoid nicks or sharp bends in  
thermostat bulb wire. Keep thermostat bulb in mounting bracket  
until ready to mount base to floor. See Optional Positioning Of  
Thermostat Sensing Bulb, page 27.  
See chart below for minimum permanent flue opening you must  
provide. Attach damper clamp so the minimum permanent flue  
opening will be maintained at all times.

INSTALLATION  
Continued  
Installation must include an equipment shutoff valve, union, and  
plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge  
hook up. NPT tap must be upstream from heater (see Figures 16 or  
17 page 13, depending on your model).  
CONNECTING TO GAS SUPPLY  
WARNING: This appliance requires a 1/2" NPT  
(National Pipe Thread) inlet connection to the pres-  
sure regulator.  
IMPORTANT: Install equipment shutoff valve in an accessible  
location. The equipment shutoff valve is for turning on or shutting  
off the gas to the appliance.  
WARNING: A qualified service person must con-  
nect heater to gas supply. Follow all local codes.  
Checkyourbuildingcodesforanyspecialrequirementsforlocating  
equipment shutoff valve to fireplaces.  
CAUTION: Never connect propane/LP fireplace di-  
rectlytothepropane/LPsupply.Thisheaterrequiresan  
external regulator (not supplied). Install the external  
regulator between the heater and propane/LP supply.  
Apply pipe joint sealant lightly to male NPT threads. This will  
prevent excess sealant from going into pipe. Excess sealant in pipe  
could result in clogged heater valves.  
WARNING: Use pipe joint sealant that is resistant  
to liquid petroleum (LP) gas.  
WARNING:Neverconnectnaturalgasfireplaceto  
private (non-utility) gas wells. This gas is commonly  
known as wellhead gas.  
We recommend that you install a sediment trap in supply line as  
shown in Figures 16 or 17 page 13, depending on your model.  
Locate sediment trap where it is within reach for cleaning. Install in  
piping system between fuel supply and heater. Locate sediment trap  
where trapped matter is not likely to freeze. A sediment trap traps  
moisture and contaminants. This keeps them from going into heater  
controls.Ifsedimenttrapisnotinstalledorisinstalledwrong,heater  
may not run properly.  
Installation Items Needed  
Before installing heater, make sure you have the items listed below.  
• external regulator (supplied by installer)  
• piping (check local codes)  
• sealant (resistant to propane/LP gas)  
• equipment shutoff valve *  
• test gauge connection *  
• sediment trap  
• tee joint  
• pipe wrench  
CAUTION: Avoid damage to regulator. Hold gas  
regulator with wrench when connecting it to gas  
piping and/or fittings (Variable Manually-Controlled  
and Thermostatically-Controlled Models Only).  
• approved flexible gas line with gas connector (if allowed by lo-  
cal codes) (not provided)  
CAUTION:Avoiddamagetogascontrol. Holdgas  
control with wrench when connecting it to gas piping  
and/or fittings (Remote-Ready Models Only).  
* A CSA design-certified equipment shutoff valve with 1/8" NPT  
tap is an acceptable alternative to test gauge connection. Purchase  
the optional CSA design-certified equipment shutoff valve from  
your dealer. See Accessories, page 36.  
External Regulator  
Propane/LP  
For propane/LP units, the installer must supply an external regula-  
tor. The external regulator will reduce incoming gas pressure. You  
must reduce incoming gas pressure to between 11 and 14 inches of  
water. If you do not reduce incoming gas pressure, heater regulator  
damage could occur. Install external regulator with the vent point-  
ing down as shown in Figure 15. Pointing the vent down protects it  
from freezing rain or sleet.  
Supply Tank  
CAUTION: Use only new, black iron or steel pipe.  
Internally-tinnedcoppertubingmaybeusedincertain  
areas. Check your local codes. Use pipe of 1/2" diam-  
eter or greater to allow proper gas volume to heater. If  
pipe is too small, undue loss of volume will occur.

INSTRUCTIONS  
WARNING  
If fireplace has glass doors, never operate this  
heater with glass doors closed. If you operate  
heater with doors closed, heat buildup inside fire-  
place will cause glass to burst. Make sure there are  
no obxtructions across openings of fireplace.

to the PILOT position. Press in control knob for five (5)  
seconds (see Figure 28).  
Note: You may be running this heater for the first time  
after hooking up to gas supply. If so, the control knob may  
need to be pressed in for 30 seconds or less. This will allow  
air to bleed from the gas system.  
7. With control knob pressed in, press and release ignitor  
button. This will light pilot. The pilot is attached to the  
front burner. If needed, keep pressing ignitor button un-  
til pilot lights.

Note: If pilot does not stay lit, contact a qualified service  
person or gas supplier for repairs. Until repairs are made,  
light pilot with match. To light pilot with match, see Manual  
Lighting Procedure, page 20.  
Note: Home owners generally prefer to operate their heater  
with the chimney damper closed. This will put all the heat into  
the room. However, there may be times you will desire the full  
flames of the HI heat setting but will find the heat output  
excessive. You can open the chimney damper (if you have one)  
fully or partially to release some of the heat.

INSPECTING BURNERS  
Check pilot flame pattern and burner flame patterns often.  
FRONT BURNER FLAME PATTERN  
Figure36showscorrectfrontburnerflamepattern. Figure37shows  
incorrect front burner flame pattern. The incorrect burner flame  
pattern shows yellow tipping at top of blue flame.  
PILOT FLAME PATTERN  
Figure 34 shows a correct pilot flame pattern. Figure 35 shows an  
incorrect pilot flame pattern. The incorrect pilot flame is not  
touching the thermocouple. This will cause the thermocouple to  
cool. When the thermocouple cools, the heater will shut down.  
WARNING: If yellow tipping occurs, your heater  
could produce increased levels of carbon monoxide.  
If front burner flame pattern shows yellow tipping,  
follow instructions at bottom of this page. Yellow  
flame on rear burner is normal.  
If pilot flame pattern is incorrect, as shown in Figure 35  
• turn heater off (see To Turn Off Gas to Appliance, page 17 [Ther-  
mostat-Controlled Models], page 18 [Manually-Controlled  
Models], or page 20 [Remote-Ready Models])  
NOTICE: Do not mistake orange flames with yellow  
tipping. Dirt or other fine particles are burned by  
heater, causing brief patches of orange flame.  
• see Troubleshooting, pages 24 through 26  
Note: The pilot flame on natural gas units will have a slight curve,  
but flame should be blue and have no yellow or orange color.

FOR MASONRY AND FACTORY-BUILT  
METAL FIREPLACE  
If your log set cycles to pilot, but the room temperature drops to a  
lower than ideal comfort level before the log set comes back on, you  
may want to reposition the thermostat sensing bulb.  
Thermostat  
Sensing  
Bulb  
The thermostat sensing bulb is located on the gas valve assembly.  
This location allows the thermostat to keep the room temperature at  
an ideal comfort level for most fireplace applications. For position-  
ing the thermostat sensing bulb elsewhere, an adhesive-backed  
mounting clip is available (see Figure 41).

3. The thermostat sensing bulb may be located to the lower right  
front side of fireplace. Determine location of sensing bulb, but  
do not mount sensing bulb until step 5. If you have a masonry  
fireplace, see Figure 43 for location.

If you have a factory-built metal fireplace, see Figure 44 for  
location.

If your fireplace has glass doors, position sensing bulb directly  
behind door gap on right bottom side (see Figure 45).

4. The mounting clip must be a minimum of 3" from bottom of  
fireplace to prevent crimping of capillary. Once you have de-  
cided on a location, clean the area thoroughly. Remove the pa-  
per backing from the adhesive on back of mounting clip. Press  
the clip into the new location so that the thermostat sensing bulb  
will be positioned vertically with the capillary at the bottom (see  
Figure 46). Slide the thermostat sensing bulb into the clip.

This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that fail or become damaged as a

Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of incidental or consequential damages, so  
the above limitation on implied warranties, or exclusion or limitation on damages may not apply to you.  
This warranty gives you specific legal rights, and you may also have other rights that vary from state to state.
