GAS LINE INSTALLATION
REMOTE SWITCH INSTALLATION
1. Thread wire through the electrical knockout located on
either side of fireplace.. 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. (Fig. 8/9)
When purging gas line the front glass must
be removed.
The gas pipeline can be brought in through the right side,
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.
HONEYWELL VALVE
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 some
additional local codes, it is always best to
consult your local authority and the CAN/
CGA-B149 (1. or .2) Installation code or for
U.S.A Installations consult the current
National Fuel Gas Code, ANSI Z223.1
Fig. 8
SIT VALVE
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.
Fig. 9
ALTERNATE SWITCH LOCATION:
Remote switch can be installed on either side of the access
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. 10)

or fan servicing. See Fig. 7. See gas specification for
pressure details and ratings.
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.

to have some amount of the horizontal vent
run immediately after the fireplace. A verti-
cal rise must be used but can be located
anywhere in the vent system, to meet the
perimeters identified in the venting graph.

Fig. 13
The maximum number of 90 degree elbows per side wall
installation is three (3).
VERTICAL SIDEWALL APPLICATIONS
The maximum number of 45 degree elbows permitted per
side wall installation is two (2). These elbows can be
installed in either the vertical or horizontal run.
Vent Starter Kit 7DVSK must be used in
Vertical Sidewall installations.
The maximum horizontal vent length is 36" (914mm) when
90º elbow is installed directly onto fireplace.
Since it is very important that the venting system
maintainitsbalancebetweenthecombustionairintake
and the flue gas exhaust, certain limitations as to vent
configurations apply and must be strictly adhered to.

The graph showing the relationship between vertical and
horizontal side wall venting will help to determine the
various vent lengths allowable. Fig. 17.
Minimum clearance between vent pipes and
combustible materials is one (1") inch (25
mm) on top, bottom and sides unless
otherwise noted.
When vent termination exits through
foundationlessthan20"belowsidingoutcrop,
the vent pipe must flush up with the siding. A
7DVSS must also be used.
Fig. 14
For each 45 degree elbow installed in the
horizontal run (while maintaining a constant
horizontal plane), the length of the horizontal
run MUST be reduced by 18" (457mm). This
does not apply if the 45 degree elbows are
installed on the vertical part of the vent sys-
tem.
It is always best to locate the fireplace in such a way that
minimizes the number of offsets and horizontal vent
length.
The horizontal vent run refers to the total
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.

If a 90 degree elbow is used in the horizon-
tal vent run (level height maintained) the
maximum horizontal vent length is reduced
by 36 inches. Fig. 15. This does not apply if
the 90 degree elbows are used to increase
or redirect a vertical rise.
HOW TO USE THE VENT GRAPH
1. Determine the height of the centre of the horizontal
vent pipe exiting through the outer wall. Using this
dimension on the Sidewall Vent Graph (Fig. 17),
locate the point it intersects 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.
The maximum number of elbow degrees in a system is
270º.

GENERAL INFORMATION ON ASSEMBLING
THE TWIST LOCK VENT PIPES
When using CFM Majestic twist lock pipe it is not neces-
VERTICAL SIDEWALL APPLICATIONS
sary to use silicone to seal the twist lock joints. The only
areas that need silicone are the collars on the fireplace,
the telescoping pipe (if used) and the horizontal termina-
tion connection (when necessary).
Vent Starter Kit 7TDVSK must be used in
Vertical Sidewall installations.
To join the pipes together, simply align the beads of the
male end with the grooves of the female end and while
joining the two together, twist the pipe until the flange on
the female end touches the external bead on the male
end. Secure the joints with three sheet metal screws.
Since it is very important that the venting system
maintainitsbalancebetweenthecombustionairintake
and the flue gas exhaust, certain limitations as to vent
configurations apply and must be strictly adhered to.
The graph showing the relationship between vertical and
horizontal side wall venting will help to determine the
various vent lengths allowable. Fig. 39.
To make easier to assembly, we suggest putting lubri-
cant (vaseline or similar) on the male end of the twist
lock pipe.
Minimum clearance between vent pipes and
combustible materials is one (1") inch (25
mm) on top, bottom and sides unless
otherwise noted.
TWIST LOCK PIPE JOINT
When vent termination exits through
foundationlessthan20"belowsidingoutcrop,
the vent pipe must flush up with the siding. A
7DVSS must also be used.
Screw Holes
Fig. 34
Crimped pipe and new twist lock pipe.
It is always best to locate the fireplace in such a way that
minimizes the number of offsets and horizontal vent
length.
It is possible to use CFM Majestic 4" & 7" direct vent
crimped pipe and elbows in your system, with the new
CFM Majestic 4" & 7" Direct Vent Twist Lock Pipe.
The horizontal vent run refers to the total
length of vent pipe from the flue collar of the
fireplace to the face of the outer wall.
You must use the crimped pipe first in the system off
the appliance.
1. Install expanded end of crimped pipe or elbow onto
the 4" & 7" collars off the fireplace with high tem-
perature sealant and 3 screws.
Horizontal plane means no vertical rise
exists on this portion of the vent assembly.
2. If you wish to continue your system with your 4" & 7"
crimped pipe or elbow apply high temperature
sealant on crimped end of pipe at 2" in from end and
fasten the next pipe with 3 sheet metal screws.
3. When you wish to continue your system with the
New Twist Lock pipe or elbow, apply high tempera-
ture sealant on crimped end of pipe at 1-1/2" from
end, and slip the female end of the twist lock pipe
over the crimped end of the pipe and secure with 3
sheet metal screws. Continue the installation with
twist lock pipe placing the female end over the male
end and fastening with 3 sheet metal screws.
For some installations, it may be desireable
to have some amount of the horizontal vent
run immediately after the fireplace. A verti-
cal rise must be used but can be located
anywhere in the vent system, to meet the
perimeters identified in the venting graph.

The maximum number of 90 degree elbows per side wall
installation is three (3).
The maximum number of 45 degree elbows permitted per
side wall installation is two (2). These elbows can be
installed in either the vertical or horizontal run.
The maximum horizontal vent length is 36" (914mm) when
90º elbow is installed directly onto fireplace.

For each 45 degree elbow installed in the
horizontal run (while maintaining a constant
horizontal plane), the length of the horizontal
run MUST be reduced by 18" (457mm). This
does not apply if the 45 degree elbows are
installed on the vertical part of the vent sys-
tem.
Example: According to the vent chart the maximum
horizontal vent length is 20' when the vertical height is 7.5'
from fireplace base height. If one 90 degree elbow is
required in the horizontal vent it must be reduced to 17'.
If a 90 degree elbow is used in the horizontal
vent run (level height maintained) the maxi-
mum horizontal vent length is reduced by 36
inches. Fig. 36. This does not apply if the 90
degree elbows are used to increase or redi-
rect a vertical rise.

HOW TO USE THE VENT GRAPH
VERTICAL SIDEWALL INSTALLATION
1. Determine the height of the centre of the horizontal
vent pipe exiting through the outer wall. Using this
dimension on the Sidewall Vent Graph (Fig. 39),
locate the point it intersects 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.
STEP 1

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 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 circustances present.

on the firebox base on either side of the burner assem-
bly.
1 . Remove front glass. (See "Glass Removal" Section)
2. Remove logs from the packaging.
Under no circumstances should this
lava rock be placed on any part of the
burner assembly.
As with all plastics — these are not toys
and should be kept away from children
and infants.
3. Place rear log (BH2) on rear bracket (ensure log is
seated properly, leveled and centered to the unit), so
it will not move from side to side and it is firmly
positioned on the bracket.
4. Place front log (BH1) on front log support. Use log's
bottom holes to locate it.
FLAME ADJUSTMENT
For fireplaces equipped with Hi/Lo valves, flame adjust-
ment is accomplished by rotating the Hi/Lo adjustment
knob located near the centre of the gas control. Fig. 59/

FLAME CHARACTERISTICS
MAINTENANCE
1. It is important to keep the burner and the burner
compartment clean. This must be done periodically,
at least once per season.
2. Clean the brass trim using a soft clean cloth, slightly
dampened withlemon oil and buff with a soft clean
cloth. Do NOT use brass polish or household
cleaners as these products will damage the brass
trim. Lemon oil can be obtaned at supermarkets or
hardware stores.
3. The optional FK24 fan does require periodic clean-
ing. Check the area under the control door and in
front of the fan and wipe or vacuum at least once a
month during the operating season.
It is important to periodically perform a
visual check of the pilot and the burner
flames. Compare them to the pictorials
illustrated below (Fig. 61, 62 and 63). If any
of the flames appear abnormal call a
service person.
3/8" - 1/2"
4. Contact your local representative to arrange an
annual service program.
CLEANING THE STANDING PILOT
CONTROL SYSTEM
SIT PILOT
Fig. 61
The burner and control system consists of:
• burner tube
• gas orifices
• 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 side
2. Let fireplace cool if it has been running.
3. Remove glass. (see Glass Removal)
4. Remove logs,
PSE PILOT

LOGS MAY BE HOT
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 - see Operating Section of Manual.
8. Reinstall glass.
Fig. 63
To obtain proper operation, it is imperative that the pilot
and burner's flame characteristics are steady, not lifting
or floating.
INSPECTING THE VENTING SYSTEM
This appliance venting system was designed and con-
structed to develop a positive flow adequate to remove flue
gases to the outside atmosphere.
Typically, the top 3/8" or 1/2" of the thermopile should be
engulfed in the pilot flame. See Fig. 61 or 62.
To adjust pilot burner (by a Qualified Service
Representative)
Any foreign objects in the venting system, except those
designed specifically for the venting system, may cause
spillage of flue gases.
1. Remove pilot adjustment cap.
2. Adjust pilot screw to provide properly sized flame.
3. Replace pilot adjustment cap.
To inspect the venting system, make sure the main gas
valve is off. Remove glass door (See Glass Door Re-
moval). Using a flashlight, check the area above the baffle
in the combustion dome. Clean if necessary.
The primary air shutter is set at factory and should only
be adjusted (if necessary) by a qualified service person.
