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 manufacturing 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.

Mantels
The height that a combustible mantel is fitted above the
fireplace is dependent on the depth of the mantel. This
also applies to the distance between the mantel leg (if
fitted) and the fireplace.
For the correct mounting height and widths refer to
Figures 2a and 2b and the Mantel Chart below.
The distances and reference points are not affected by
the fitting of a bay window front trim kit.
Noncombustible mantels and legs may be installed at
any height and width around the appliance.
When using a paint or lacquer to finish the mantel,
such paint or lacquer must be heat resistant to prevent
discoloration.

Gas Line Installation
When purging gas line the fornt glass must
be removed. Purging gas lines must comply 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. Knockouts are provided at convenient locations to allow for
the gas pipe installation and testing of any gas connection. 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 municipalities 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 provide 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. Refer to gas specification for pressure details and ratings.
NOTE: If flex connector is used, it must be kept inside
of the appliance. (Fig. 5)
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

Glass Cleaning
It is 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 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 recommended). 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 children 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
10
bottom holes to locate the logs on top of the studs.

Test Chimney Draw
A "Chimney Draw" test must be made before the installation is complete.
1. Close all doors and windows in the home and start
exhaust fans in the kitchen and bathroom.
2. Light unit and operate for 5 minutes.
3. Hold an ignited match, cigarette, or smoke match in
front of the unit. Refer to Figure 17 for location of the
draft hood opening.
4. Check to make sure smoke from the match, cigarette
or smoke match is drawn into the fireplace. If it is
not, turn the unit off and check for causes creating
the lack of adequate draft.
Do not operate the unit until lack of adequate draft has been determined and
rectified.

Inspecting the Venting System
This appliance venting system is designed and constructed 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
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 appliance 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 disappears 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 assembly, 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.

was correctly connected when the unit was installed,
the fan lead can be directly plugged into the EB-1
plug socket.

The fireplace, when installed must be electrically
connected and grounded in accordance with local
codes or, in the absence of local codes, with the
current CSA C22.1 Canadian Electrical Code or for
US installations, follow local codes and the National
Electrical Code, ANSI/NFPA No. 70.
Hard (Direct) Wire Hook-Up
First connect the ground wire to the ground stud located
on the base of either box. Black wire from supply
should connect to the variable speed switch. Alternate
speed switch wire connects to temperature sensor. Alternate lead from sensor connects to fan. Alternate fan
lead connects back to the white supply wire. (Fig. 23)
Any electrical rewiring of this fan must be
completed by a qualified electrician.
Turn off all power before hook-up.
