Installation & Operating Instructions
This gas appliance should be installed by a qualified installer in
accordance with local building codes and with current CSA-
B149.1 Installation codes for Gas Burning Appliances and
Equipment. FOR U.S. Installations follow local codes and/or the
current National Fuel Gas Code ANSI Z223.1/NFPA 54.
WARNING: Check with your electronics manufacturer
before installing a television or other electronic de-
vice above this fireplace.
IMPORTANT:
In the Commonwealth of Massachusetts, all gas fittings and
installation of this heater shall only be done by a licensed gas
fitter or licensed plumber.
PLEASE READ THE FOLLOWING CAREFULLY
It is normal for fireplaces fabricated of steel to give off some
expansion and/or contraction noises during the start up or
cool down cycle. Similar noises are found with your furnace
heat exchanger or car engine.
FOR SAFE INSTALLATION AND OPERATION OF YOUR
GAS FIREPLACE PLEASE NOTE THE FOLLOWING:
1. This appliance gives off high temperatures and should be
located out of high traffic areas and away from furniture and
draperies.
2. Children and adults should be alerted to the hazards of the
high surface temperatures of this appliance and should stay
away to avoid burns or ignition of clothing.
It is not unusual for your gas fireplace to give off some odor
the first time it is burned. This is due to the curing of the paint
and any undetected oil from the manufacturing process.
Please ensure that your room is well ventilated - open
all windows.
3. Children should be carefully supervised when they are in the
same room as your appliance.
4. Under no circumstances should this appliance be modified.
Parts removed for servicing should be replaced prior to
operating this appliance again.
It is recommended that you burn your fireplace for at least ten
(10) hours the first time you use it. If optional fan kit has been
installed, place fan in the "OFF" position during this time.
5. Installation and any repairs to this appliance should be car-
ried out by a qualified service person. A professional service
person should be contacted to inspect this appliance an-
nually. Make it a practice to have all of your gas appliances
checked annually. More frequent cleaning may be required
due to excess lint and dust from carpeting, bedding material,
etc.

Mantels
When the unit is installed into a woodburning fireplace,
the minimum distance the mantel can be placed above
the fireplace is governed by local building codes appli-
cable to woodburning fireplaces. Consult local authori-
ties having jurisdiction for these clearances.
37¹⁄₄" (946mm)
For applications requiring the use of a Zero Clearance
Kit, the minimum height a mantel can be installed above
the fireplace is 24" (610 mm) from the top of the upper
louvres. The maximum mantel depth is 8" (203 mm).
(Fig. 2)

Zero Clearance Applications
Fig. 2 Minimum mantel height above fireplace.
An alternate air supply is recommended
with this component.
Framing & Finishing
For Zero Clearance Kit applications, it is important to
determine the finished facing material before beginning
to frame. This will allow for the thickness of the finishing
material between the frame and the fireplace trim.
For installation other than in existing wood-
burning fireplaces such as new construction or renova-
tion projects, a Zero Clearance Kit must be used. The
kit enables these inserts to be installed in combustible
environments. Whenever using a Zero Clearance Kit,
consideration must be given to the dimensions of the
Zero Clearance Kit and the requirements of the Air Kit.
Similarly, consideration must be given to the 1" inch
depth of the air inlet channel sitting on the fireplace
base. Finishing material for the hearth should be flush
with the top of the air inlet channel.
NOTE: If a Zero Clearance Kit is required for mod-
els LHECDV20/LHERDV20/LHECDV30/LHERDV30
Direct Vent Inserts, only the CFM Corporation zero
clearance kit HEZC combined with the HEDVCAK is
approved to be used. Refer to Page 9, figure 10 for
HEDVCAK chimney adapter kit installation. When
using the HEZC with insert models LHECDV20 or
LHERDV20, the Trim Closure Kit, LHE20TCK, must
also be installed.
If the fireplace is installed at floor level a noncombus-
tible hearth must extend a minimum 12" (305 mm) in
front of the fireplace.
If the fireplace is recessed into the wall and at least 12"
(305 mm) above floor level, no hearth is required.
The use of wallpaper adjacent to this fire-
place is not recommended as high tem-
peratures given off by this fireplace may
adversely effect the binders in the adhe-
sive used to apply the wallpaper.

Preparation
Before beginning, remove glass door and logs from
unit. Also check to make sure there is no hidden
damage to the unit. Take a minute and plan out the
gas,venting and electrical route. It is best to start with
the gas line first followed by the chimney liner. (Refer to
Page 9)
Gas Line Installation
When purging the gas line, the front glass
must be removed.
If gas piping from the source to the heater
location has not been accomplished, install the required
pipe. Consult local plumbing code to assure proper pipe
size.
The gas pipeline can be brought in through the rear or
the base of the heater.
Units: GIDN4B0, J23KC0, GIDN3B0, GIDN3H0,
GIDL3H0, M22KC0, M22LC0, M31A30
NOTE: The gas line connection can be made of either
properly tinned 3/8" copper tubing, 1/2" rigid pipe or
an approved flex connector then reduced to 3/8" to the
heater. Some municipalities have additional local codes,
it is always best to consult your local authority and the
CSA- B149.1 installation code.

Always check for gas leaks with a mild
soap and water solution. Do not use an
open flame for leak testing.
The gas control is equipped with a captured screw
type pressure test point, therefore it is not necessary to
provide a 1/8" test point up stream of the control.
These gas inserts are approved for installation
in solid fuel burning masonry or zero clearance
fireplaces.
When using copper or flex connector, use only
approved fittings. Always provide a union when
using black iron pipe so the gas line can be easily
disconnected for burner or fan servicing. See gas
specifications for pressure details and ratings. NOTE:
If flex connector is used, it must be kept inside of the
heater.
High Elevations
Input ratings are shown in BTU per hour and are
certified without deration for elevations up to
4,500 feet (1,370m) above sea level.
For elevations above 4,500 feet (1,370m) in USA,
installations must be in accordance with the
current ANSI Z223.1/NFPA 54 and/or local codes
having jurisdiction.
In Canada, please consult provincial and/or local
authorities having jurisdiction for installations at
elevations above 4,500 feet (1,370m).

It will be necessary to clean the glass periodically.
During start-up condensation, which is normal, forms on
the inside of the glass and causes lint, dust and other
airborne particles cling to the glass surface. Also initial
paint curing may deposit a slight film on the glass. It is
therefore recommended that the glass be cleaned two
or three times with a non-ammonia household cleaner
and warm water (we recommend gas fireplace glass
cleaner). After that the glass should be cleaned two or
three times during each heating season depending on
the circumstances present.

First Firing
Flame Characteristics
Upon completing the gas line connection, a small
amount of air will be in the lines. When first lighting unit
with pilot light, it will take a few minutes to purge them-
selves of this air. Once the purging is complete, the
pilot and burner will light and operate as indicated in the
instruction manual. Subsequent lightings of the heater
will not require such purging.
It is important to periodically perform a visual check of
the pilot and the burner flames. Compare them to the
Figure 26 and Figure 27 or 28. If any of the flames ap-
pear abnormal call a service person.
PSE Pilot
3/8" - 1/2"
When lit for the first time, the appliance will emit a slight
odor for awhile. This is due to paint and lubricants used
in the manufacturing process. After each lighting, vapor
may condense and fog the glass; this moisture disap-
pears within a few minutes of burning.

NOTE: Before trouble shooting the gas control system, be sure external gas shut off is in the “On” position.
WARNING: Before doing any gas control service work, remove glass front.
SYMPTOM
POSSIBLE CAUSES
CORRECTIVE ACTION
1.Spark ignitor will not light
A. Defective or misaligned
electrode at pilot.
Using a match, light pilot. If pilot lights, turn off
pilot and push the red button again. If pilot will not
light - check gap at electrode and pilot-should be
1/8" to have a strong spark.
B. Defective ignitor (Push Button)
Push Piezo Ignitor Button. Check for spark at
electrode and pilot. If no spark to pilot, and elec
trode wire is properly connected, replace ignitor.
2. Pilot will not stay lit after
carefully following lighting
instructions.
A. Defective pilot generator
(thermocouple), remote wall
switch.
Check pilot flame. Must impinge on thermo
couple/thermopile. Note: this pilot burner assem
bly utilizes both-a thermocouple and a thermopile.
The thermocouple operates the main valve
operation (On and Off). Clean and or adjust pilot for
maximum flame impingement on thermopile and
thermocouple.
B. Defective automatic valve
Turn valve knob to “Pilot”. Maintain flow to pilot;
milivolt meter should read greater than 10 mV. If
the reading is okay and the pilot does not stay on,
replace the gas valve. Note: An interrupter block
(not supplied) must be used to conduct this test.
3. Pilot burning, no gas to
main burner
A. Wall switch or wires defective
Check wall switch and wires for proper connec
tions. Jumper wire accross terminals at wall
switch, if burner comes on, replace defective wall
switch. If okay, jumper wires across wall switch
wires at valve, if burner comes on, wires are faulty
or connections are bad.
B. Thermopile may not be
generating sufficient
millivoltage.
1. Be sure wire connections from thermopile at
gas valve terminals are tight and thermopile is
fully inserted into pilot bracket.
2. One of the wall switch wires may be grounded.
Remove wall switch wires from valve terminals if
pilot now stays lit, trace wall switch wiring for
ground. May be grounded to fireplace or gas
supply.
3. Check thermopile with millivolt meter. Take
reading at thermopile terminals of gas valve.
Should read 250-300 millivolts (minimum 150)
while holding valve knob depressed in pilot
position and wall switch “Off”. Replace faulty
thermopile if reading is below specified minimum.
C. Plugged burner orifice.
Check burner orifices for debris and remove.
D. Defective automatic valve
operator.
Turn valve knob to “On”, place wall switch to “On”
millivolt meter should read greater than 100 mV. If
the reading is okay and the burner does not come
on, replace the gas valve.
4. Frequent pilot outage
problem.
A. Pilot flame may be too low
or blowing (high) causing the
pilot safety to drop out.
Clean and/or adjust pilot flame for maximum flame
impingement on thermopile and thermocouple.
B. Possible blockage of the vent
terminal.
Check the vent terminal for blockage (recycling the
flue gases)

2. LED will blink after every valid command received by
the transmitter; this is not an error.
If a lower or higher fan speed is desired when operating
in the AUTO mode, the fan speed can be overridden by
pushing the fan button followed by the up or down key.
Pushing a key once will change the fan level by one
unit. In this mode “AUTO” is displayed next to the flame
icon and “MANUAL” is displayed next to the fan icon.
3. Failure codes may occur anytime after pilot burner is
lit.
4. Sequence is failure code followed by light not blink-
ing for 30 seconds.
5. In the event of multiple failure codes, next failure
code follows previous failure code by approximately
3 seconds.
Change Between F/C Temperature Units
Push the up and down arrow keys simultaneously for
at least 3 seconds to toggle between Fahrenheit and
Celsius units.
If an Error Code 3 is observed while performing the
testing, complete the following:
Disable Thermostat Function
1. Make sure the spade connectors are pushed all the
way on. If the Error Code 3 is still showing, then go
to the next step.
To disable the thermostat function in the AUTO mode,
push the time and down keys simultaneously for at least
3 seconds.
2. Switch the front two thermopile leads with the back
two. Be sure the white lead is connected to the
spade with the white dot next to it. If the Error Code
3 is still showing, replace the thermopiles.
To Change Batteries
1. Remove cover on the backside of the transmitter.
Install 3 AAA batteries as shown and reattach cover.
If an Error Code 8 is observed while performing the
testing, complete the following:
2. Once steps 1-3 in OPERATION are completed,
receiver/valve and transmitter are now ready. Press
any button on transmitter for recognition process to
occur between the receiver/valve and transmitter.
1. Confirm the valve is not in REMOTE mode.
• If the valve is producing Error Code 8 and in RE-

Maintenance
Burner and Burner Compartment
ally inspect pilot. Brush or blow away any dust or lint
accumulation. If pilot orifice is plugged, disassembly
may be required to remove any foreign material from
the orifice or tubing.
It is important to keep the burner and the burner
compartment clean. At least once per year the logs and
lava rock/ember material should be removed and the
burner compartment vacuumed and wiped out. Remove
and replace the logs as per the instructions in this
manual.
To obtain proper operation, it is imperative that the pilot
and burner's flame characteristics are steady, not lifting
or floating.
Always handle the logs with care as they
are fragile and may also be hot if the
fireplace has been in use.
Typically, the top 1/8" of the thermopile should be en-
gulfed in the pilot flame. (Page 12, Fig. 22)
Trim Cleaning
Fan Assembly
Clean the trim with a soft clean cloth, slightly dampened
with lemon oil and buff with a soft dry cloth. Do not use
brass polish or household cleaners as these products
will damage the trim. Lemon oil can be obtained at
supermarkets or hardware stores.
The fan unit requires periodic cleaning. At least once
per month in the operating season, open the lower
louvre panels and wipe or vacuum the area around the
fan to remove any build up of dust or lint.
Cleaning the Standing Pilot
Control System
The burner and control system consists of:
• main burner
• gas orifice
• pilot burner
• thermopile
• combination millivolt gas valve
Most of these components may require only an occa-
sional checkup and cleaning and some may require ad-
justment. If repair is necessary, it should be performed
by a qualified technician.
In order to properly clean the burner and pilot assembly,
turn off the gas to the unit, remove the window frame
panel and logs exposing the burner and pilot assembly.
Clean all foreign materials from the top of the burner.
Check to make sure that burner parts are clean. Visu-
