IMPORTANT:
PLEASE REVIEW THE FOLLOWING CAREFULLY
Remove any plastic from from 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 from the manufacturing process.
Please ensure that your room is well ventilated-open
all windows.
It is recommended that you burn your fireplace for at least
ten (10) 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.

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).
Gas Line Installation
When purging gas line, the front window
frame removed.
The gas pipeline can be brought in through the rear
of the fireplace as well as the bottom. Knockouts are
provided on the bottom behind the valve 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
rear right side of the valve 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, 3/8” rigid pipe or an approved
flex connector. Since some municipalities have additional local codes, it is always best to con- sult your
local authority and the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 in the USA or the CSA-B149.1 installation codes.
1/2” Gas Supply
1/2” NPT X 1/2” Flare Shut-off Valve

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.
Remote ON/OFF Switch
Installation:
1. Thread the wiring through holes on the end panels
of appliance. Take care not to cut wire or insulation
on metal edges. Route the wire to a conveniently
located receptacle box.
2. Attach the wire to the ON/OFF switch and install the
switch into the receptacle box.
3. Connect the other ends of the wire to the gas control
valve. (Fig. 6)

Alternate Switch Location
The remote switch can be installed on the front/side of
the access door. Simply mount the switch to the bracket
provided and screw the bracket to either side of the
frame, lining up the screws with the pre-punched holes.
(Fig. 7)
FP297A
Fig. 5 Typical gas supply installation.
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.
When using copper or flex connector use only approved
fittings. Always provide a union when using black iron
pipe so that the gas line can be easily disconnected for
burner or fan servicing . See gas specifications for pressure details and ratings.

Twist Lock Pipes
When using CFM Corporation twist-lock pipe it is not
necessary to use sealant on the joints. The only areas
of the venting system that need to be sealed with high
temperature silicone sealant are the sliding joints of any
telescopic vent section used in the system.
To join the twist lock pipes together, simply align the
beads of the male end with the grooves of the female
end, then while bringing the ends together, twist the
pipe until the flange on the female end contacts the
external flange on the male end. It is recommended that
you secure the joints with three (3) sheet metal screws,
however this is not mandatory with twist lock pipe.
To make it easier to assemble the joints we suggest
putting a lubricant (Vaseline or similar) on the male end
of the twist lock pipe prior to assembly.

How to Use the Vent Graph
The vent chart should be read in conjunction with the
following vent installation instructions to determine the
relationship of the vertical and horizontal dimensions of
the vent system.
1. Determine the height of the center of the horizontal
vent pipe exiting through the outer wall. Using this
dimension on the Sidewall Vent Graph. (Fig. 13)
locate the point intersecting with the slanted graph
line.
2. From the point of this intersection, draw a vertical
line to the bottom of the graph.
3. Select the indicated dimension, and position the
fireplace in accordance with same.
Example A:
If the vertical dimension from the floor of the fireplace
is 11’ (3.4 m) the horizontal run to the face of the outer
wall must not exceed 14’ (4.3 m).
Example B:
If the vertical dimension from the floor of the unit is 7’
(2.14 m), the horizontal run to the face of the outer wall
must not exceed 8¹⁄₂’ (2.6 m).

Vertical Sidewall Applications
Since it is very important that the venting system maintain its balance between
the combustion air intake and the flue
gas exhaust, certain limitations as to vent
configurations apply and must be strictly
adhered to.
The vent graph showing the relationship between vertical and horizontal side wall venting will help to determine the various dimensions allowable.
Minimum clearance between vent pipes
and combustible materials is one 1”
(25mm) on top, bottom and sides unless
otherwise noted.
When the vent termination exits through foundations
less than 20” (508mm) below siding outcrop, the vent
pipe must flush up with the siding.
It is always best to locate the fireplace in such a way
that minimizes the number of offsets and horizontal
vent length of vent pipe from the flue collar of the fireplace to the face of the outer wall.

Horizontal plane means no vertical rise exists on this
portion of the vent assembly.
• The maximum number of 90° elbows per side wall
installations is three (3).
• If a 90° elbow is fitted directly onto the fireplace
flange the maximum horizontal vent run before the
termination or a vertical rise is 36” (914mm).
• If a 90° elbow is used in the horizontal vent run
(level height maintained) the maximum horizontal
vent length is reduced by 36” (914mm). This does
not apply if the 90° elbows are used to increase or
redirect a vertical rise.
Example: According to the chart the maximum
horizontal vent length in a system with a 7.5’ (2.3 m)
vertical rise is 20’ (6m) and if a 90° is required in the
horizontal vent it must be reduced to 17’ (5.2 m).
In Figure 16, Dimension A plus B must not be
greater than 17’ (5.2 m).

FP1238
Fig. 16 Maximum vent run with elbows.
• The maximum number of 45° elbows permitted per
side wall installation is two (2). These elbows can be
installed in either the vertical or horizontal run.
• For each 45° elbow installed in the horizontal run,
the length of the horizontal run MUST be reduced by
18” (457 mm). This does not apply if the 45° elbows
are installed on the vertical part of the vent system.
• The maximum number of elbow degrees in a system
is 270°. (Fig. 17)

STEP 7
Guide the vent terminations 4” and 7” collars into their
respective vent pipes. Double check that the vent pipes
overlap the collars by 2” (51 mm). Secure the termination to the wall with screws provided and caulk around
the wall plate to weatherproof. (Fig. 23) As an alternative to screwing the termination directly to the wall you
may also use expanding plugs or an approved exterior
construction adhesive. You may also attach the termination with screws through the inner body into the 4”
(102 mm) vent pipe however for this method you must
extend the 4” (102 mm) pipe approximately 6” (152
mm) beyond the outer face of the wall.

Step 3
Install the four (4) spacer springs on the 4” flex vent
pipe. When installing the spacer springs around the 4”
pipe, stretch the spring to approximately 15” (381 mm),
wrap the spring around the pipe and interlock the ends
of the spacer spring approximately 2” (51 mm). Measure 6³⁄₄” (172 mm) from the end of the pipe. Place the
next spring 5” (127 mm) from the previously installed

Below Grade Installations
When it is not possible to meet the required vent terminal clearances of 12” (305mm) above grade level a
snorkel vent kit is recommended. It allows installation
depth of down to 7” (178mm) below grade level. The 7”
is measured from the center of the horizontal vent pipe
as it penetrates through the wall.
If venting system is installed below
ground, we recommend a window well with
adequate and proper drainage.
Ensure sidewall venting clearances are observed.
If installing a snorkel a minimum 24” (610 mm) vertical
rise is necessary. The maximum horizontal run with
the 24” (610 mm) vertical pipe is 36” (914 mm). This
measurement is taken from the collar of the fireplace
(or transition elbow) to the face of the exterior wall.
Refer to the Sidewall Vent Graph for extended
horizontal run if the vertical rise exceeds 24” (610 mm).

Glass Cleaning
It is necessary to periodically clean the glass. During
start-up condensation, which is normal, forms on the
inside of the glass. This condensation 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 that the glass be
cleaned two or three times with a non-ammonia based
household cleaner and warm water (We recommend
gas fireplace glass cleaner) within the first few weeks of
operation.
After the initial cleaning process the glass should be
cleaned two or three times during each operating
season depending on the environment in the house.
Clean the glass after the first two weeks of
operation.
Do not clean glass when hot.
Do not use abrasive cleaners.
Do not strike or slam glass.

CONVERTING THE APPLIANCE FROM LP TO
NATURAL GAS OR NATURAL GAS TO LP
The conversion of this appliance from one
gas to another must be carried out by an
authorized service provider.
The procedure for converting from one gas
to another is the same regardless of the
initial gas used. The only variation is in the
orifice-sizes and component part numbers.
Your authorized service provider will
ensure the correct parts are used.
1. Disconnect power to unit and shut off gas supply.
2. Remove window frame assembly.
3. Carefully remove the logs & lava rock material.
4. Remove the screws that are holding the burner
housing assembly in place.
5. Remove the burner housing assembly. Depending
on the model of the appliance you may have to loosen the pilot bracket retaining screw/nut to allow the
pilot and bracket assembly to tilt and give enough
clearance to remove the burner housing assembly.
6. For Model 36LDVT ONLY: Remove the rear log
support and relocate the two (2) screws that locate
the rear log as shown in Figure 45.
9. PSE Pilot
Using a suitable wrench on the hexagonal body, un-
screw the pilot hood assembly from the pilot, do not
twist the hood itself. Remove the orifice and replace
it with the new orifice supplied in the kit. Refit the
pilot hood assembly. Do not over-tighten the pilot
hood. The hood must return to its original alignment.
Take care not to damage the thermocouple, thermopile or igniter.

c. Install the enclosed identification label (F) to the
valve body where it can be easily seen.
Honeywell Gas Control Valve (Fig. 47)
The Honeywell valve fitted to this unit is suitable for
use with LP or Natural Gas. It is converted to the
required gas application by the installation of a color
coded “conversion screw”.
a) Using a suitable small screwdriver lift out the
central regulator cap from the “Hi - Lo” knob on
the valve.
b) Unscrew the exposed conversion screw.
c) Insert the new color coded conversion screw.
Do not over-tighten the screw, it must be finger
tight.
d) Refit the regulator cap.
e) Mount the conversion label supplied with con-
version screw to the valve in a visible position.
11. Reassemble the fireplace in the reverse order, except for the window frame assembly. Leave this off
until after the unit has been checked for leaks and
the gas supply has been bled.

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 refit 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/FK12 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.
Cleaning the Standing
Pilot Control System
The burner and control system consist of:
• burner • gas orifice
• pilot assembly • thermopile
• millivolt gas valve
Most of these components may require only an
occasional checkup and cleaning and some may
require adjustment. If repair is necessary, it should
be performed by a qualified technician.
1. Turn off pilot light at gas valve.
2. Allow fireplace to cool if it has been operating.
3. Remove window frame assembly. (Refer to Window
Frame Assembly Removal section.)
4. Remove logs.
5. Vacuum burner compartment especially around
orifice primary air openings.
6. Visually inspect pilot. Brush or blow away any dust
or lint accumulation.
7. Reinstall logs.
8. Ignite pilot - Refer to Lighting Instructions.
9. Reinstall window frame assembly.
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” to 1/2” of the thermopile should
be engulfed in the pilot flame. (Refer to Page 24, Figure
43)
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
technician.

Fan Kits
FK24 Fan Assembly
This auxiliary fan system increases the efficiency of the
circulation of the heating air.
The FK24 fan kit allows variable speed control of the
circulation fan and also incorporates a heat sensor in
the circuit.
Specifications
115 Volt / 60Hz / 56 Watts
Maintenance
The fan itself does not require regular maintenance,
however periodic cleaning of the fan and the
surrounding area is required.
Check the area under the control door (lower louvre
assembly) and in front of the fan and wipe or vacuum this
area at least once a month during the operating season.
Installation
The fan assembly and other components are supplied
fully wired eliminating the need for a licensed electrician
to carry out the installation.
If hard wiring the fan using Method B (following), we
strongly recommend the use of a licensed electrician.
1. Open the lower louvre assembly. Maneuver the fan
& bracket assembly around the gas valve and lines
to locate the unit onto the screw studs on the back of
the fireplace.
2. Install the thermal sensor under the bottom of the of
the firebox, locating it over the two 10 mm studs and
secure it with nuts.
3. Locate the fan speed control unit. This can be fitted
behind the lower louvre assembly as in Figure 48
or located remotely in a conveniently located wall
mounted electrical box. Remote location of the
speed control will require suitable extension of the
component wiring.
4. The power supply may be connected in two ways:
Method A
Route the 6’ lead fitted to the unit to a conveniently
located wall socket.
Method B (Using EB-1 Receptacle Box)
The EB-1 receptacle box (Pt. # ZA1200) may be
hard wired into the house supply. The fan lead is
then plugged into the EB-1 box. For instruction on
wiring the EB-1 Electrical Junction Box see the
earlier chapter in the Installation section of this
manual.
