IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
Remove any plastic from trim parts before turning the
fireplace ON.
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.
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 used in the manu-
facturing process.
Please ensure that your room is well ventilated -
open all windows.
It is recommended that your burn your fireplace for at
least ten (10) continuous hours the first time you use
it. If the optional fan kit has been installed, place the
fan switch in the “OFF” position during this time.
WARNING: Check with your electronics manufacturer
before installing a television or other electronic de-
vice above this fireplace.

Gas Line Installation
When purging gas line the fornt glass must
be removed. Purging gas lines must com-
ply with ANSI Z223.1/NFPA 54 in USA and
CSA B149.1 in Canada.
The gas pipeline can be brought in through the right or
left side of the appliance, as well as the bottom. Knock-
outs are provided at convenient locations to allow for
the gas pipe installation and testing of any gas connec-
tion. It is most convenient to bring the gas line in from
the right side, as this allows fan installation or removal
without disconnecting the gas line.
The gas line connection can be made with properly
tinned 3/8" copper tubing, 1/2" rigid pipe or an approved
flex connector, then reduced to 3/8" (R Models) or 1/2"
(E Models) to the appliance. Because some municipali-
ties have some additional local codes, it is always best
to consult your local authority and the CSA-B149.1
installation code.
For US installations consult the current National Fuel
Gas Code, ANSI Z223.1/NFPA 54 .
Always check for gas leaks with a mild
soap and water solution applied with a
brush no larger than 1" (25mm). Never
aply soap and water solution with a spray
bottle. Do not use an open flame for leak
testing.
The fireplace valve must not be subjected
to any test pressures exceeding 1/2 psi.
Isolate or disconnect this or any other gas
appliance control from the gas line when
pressure testing.
The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to pro-
vide a 1/8" test point up stream of the control.
When using copper or flex connector use only approved
fittings. Always provide a union so that gas line can
be easily disconnected for burner or fan servicing. Re-
fer to gas specification for pressure details and ratings.
NOTE: If flex connector is used, it must be kept inside
of the appliance. (Fig. 5)
Remote Switch Installation
1. Thread wire through the electrical knockout located
on either side of unit. Do not cut wire or insulation on
metal edges. Ensure that wire is protected. Run the
other end to a conveniently located wall receptacle
box.
2. Attach wire to switch and install switch into receptacle
box. Attach cover plate to switch.
3. Connect wiring to gas valve. (Figs. 19 or 20, Page
14)
Alternate Switch Location
Remote switch can be installed on either side of the ac-
cess door. Simply mount the switch to the switch bracket
provided. Screw the bracket on either side of the frame,
lining up the screws with the pre-punched holes. (Fig. 7)

Glass Cleaning
It is necessary to clean the glass periodically. Dur-
ing start-up, condensation, which is normal, forms on
the inside of the glass and causes lint, dust and other
airborne particles to cling to the glass surface. Also
initial paint curing may deposit a slight film on the glass.
It is therefore recommended the glass be cleaned two
or three times with a non-ammonia household cleaner
and warm water (gas fireplace glass cleaner is recom-
mended). After initial use glass should be cleaned two
or three times during heating season.
Clean glass after first two weeks of opera-
tion.
Do not clean glass when hot.
Do not use abrasive cleaners.
Do not strike or slam the glass.
Log Installation
1. Remove window frame assembly. (Refer to Page xx)
2. Remove logs from the packaging.
As with all plastic, these bags are not toys
and should always be kept away from chil-
dren and infants.
3. Place rear log on back bracket. Ensure that log is
firmly positioned and there is no side-to-side move-
ment.
4. Place the front log on top of the burner, use bottom
holes to locate the logs on top of the studs.
5. Place the front right log on top of the burner, Use
bottom holes to locate the logs on top of the studs.

Inspecting the Venting System
This appliance venting system is designed and con-
structed to develop a positive flow adequate to remove
flue gases to the outside atmosphere.
Any foreign objects in the venting system, except those
designed specifically for the venting system, may cause
spillage of flue gases.
To inspect the venting system, make sure the main gas
valve is off. Remove the window frame assembly (Refer
to Page 10). Using a flashlight, check the area above
the baffle in the combustion dome. Clean if necessary.
FP1197
draft test location
2/27/02 djt
Test for Draft at This Location
FP1197
Fig. 17 Draft test location.
First Firing
Remove window frame assembly before lighting.
Upon completing the gas line connection, a small
amount of air will be trapped in the line. When first
lighting the unit with pilot light, it will take a few minutes
to purge the trapped air. Once purging is complete, the
pilot and burner will light and operate as indicated in the
instruction manual. Subsequent lightings of the appli-
ance will not require purging.
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.

Vent Safety Switch
This fireplace incorporates the use of a Vent Safety
Shut-off Switch. The sensor and wiring are factory
installed and should not be removed or altered during
installation.
In the event of total flue blockage the system will detect
the increased heat buildup and will automatically shut
down the main burner assembly.
The sensor is located above the firebox behind the top
louvre assembly. It is accessible by removing the top
louvre assembly.
CAUTION: The firebox, Vent Safety Switch sensor
and surrounding panels become very hot during
normal operation. Allow time for the components to
cool before carrying out any service or inspection.
If the sensor is activated and shuts off the burner as-
sembly, the following procedure should be followed:
• Observe that the pilot flame is still ON. If the pilot
flame has gone out the reason for the fireplace shut
down is not the vent safety switch.
• Turn the pilot flame OFF and close all controls. Allow
the fireplace to cool.
• Check the flue and venting components for blockage
or restrictions.
• Remove the front louvre assembly.
• Locate the sensor.
• Reset the sensor by pressing the reset pin between
the two wire terminals. (Fig. 18)
CAUTION: The components may still be hot.
• Light the fireplace and check for downdrafts.
• Operate the fireplace in the normal manner. If the
burner assembly shuts down again after a period
of operation, DO NOT ATTEMPT TO RESET THE
SENSOR AGAIN. Turn off the fireplace and contact
your service technician.
Electrical Connection
The sensor is wired in series between the wall mounted
ON/OFF switch and the Electronic Ignition Module (Fig.

Maintenance
Burner and Burner Compartment
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.
Always handle the logs with care as they
are fragile and may also be hot if the
fireplace has been in use.
FK24 Fan Assembly
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.
Brass Trim
Clean the brass trim pieces using a soft cloth lightly
dampened with lemon oil. Do not use water or
household cleaners on any brass components.
To obtain proper operation, it is imperative that the pilot
and burner’s flame characteristics are steady, not lifting
or floating.
Typically, the top 3/8” or 1/2” of the thermopile should
be engulfed in the pilot flame. (Fig. 21)
To adjust pilot burner; (by qualified service technician)
1. Remove pilot adjustment cap.
2. Adjust pilot screw to provide properly sized flame.
3. Replace pilot adjustment cap.
The primary air shutter is set at factory and should only
be adjusted, if necessary, by a qualified service techni-
cian.
