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 3a and 3b, and the following Mantel Charts.
The fitting of a bay window trim kit does not effect the
distances and reference points referred to in the

Final Finishing
Noncombustible materials such as brick or tile may be
extended over the edges of the face of the fireplace.
DO NOT cover any vent or grille panels.
The gas line connection can be made with properly
tinned 3/8” copper tubing, 3/8” rigid pipe or an ap-
proved flex connector. Since some municipalities have
additional local codes, it is always best to consult your
local authority and the National Fuel Gas Code, ANSI
Z223.1 in the USA or the CSA-B149.1 installation
code.
If a Trim Kit is going to be installed on the fireplace, the
brick or tile will have to be installed flush with the
edges of the fireplace.

open flame for leak testing.
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)
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 ap-
proved fittings. Always provide a union when using
black iron pipe so the gas line can be easily discon-
nected for burner or fan servicing. See gas specifica-
tion for pressure details and ratings.
The fireplace valve must not be subjected to any test
pressures exceeding 1/2 psi. Isolate or disconnect this
and any other gas appliance control from the gas line
when pressure testing.
Remote ON/OFF Switch
Installation
1. Thread the wiring through the holes on the end
panels of the fireplace. Take care not to cut the wire
or insulation on metal edges. Route the wire to a
conveniently located receptacle box.
Fig. 7 Alternate switch location.
Do not wire the remote ON/OFF wall
switch for the gas fireplace to the 120
volt power supply.
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)

General Information on Assembling DV Components
Crimped End Pipes
Before joining elbows and pipes apply a bead of high
1" (25mm)
temperature sealant to the crimped end of the elbow or
pipe. Join the pipes using a 2” (50mm) overlap and
secure the joints with three sheet metal screws. (Fig. 9)
Wipe off excess sealant.

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 collars on the
fireplace and termination, and the sliding joint 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 pipe 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
Rear Wall Vent Applications
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.
NOTE: It is not necessary to seal the vent pipe
joints for any straight out of the wall rear vent
applications.
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. 11)
locate the point intersecting with slanted graph line.
2. From the point of this intersection, draw a vertical
line to the bottom of the graph.
NOTE: Vent Starter Kit Model 7TDVSK or 7DVSK
must be used in straight out of the wall rear
vent applications.
Maximum Vent Length......20” (508 mm) (Fig. 12)
Minimum clearance between vent pipes
and combustible materials is one (1”)
inch (25 mm) on the sides and two (2”)
inches (50 mm) on top.
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’ (3.4m) the horizontal run to the face
of the outer wall must not exceed 14’ (4.3m).
Example B:
If the vertical dimension from the floor of the unit is
7’ (2.14m), the horizontal run to the face of the outer
wall must not exceed 8¹⁄₂’ (2.6m).
When vent termination exits through
foundation less than 20” (508 mm) below
siding outcrop, the vent pipe must flush
up with the siding.

Vertical Sidewall Applications
Since it is very important that the vent-
ing 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 shows the relationship between
vertical and horizontal side wall venting and will help to
determine the various dimensions allowable.

Minimum clearance between vent pipes
and combustible materials is one

unless otherwise noted.
Side View
CFM142
Fig. 18 Maximum horizontal vent run before termination.
When vent termination exits through foundations less
than 20" 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.
• If a 90° elbow is used in the horizontal vent run
(level height maintained) the maximum horizontal
vent length is reduced by 36" (914 mm). (Fig. 18)
This does not apply if the 90° elbows are used to
increase or redirect a vertical rise. (Fig. 19)
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.

• IMPORTANT • Minimum clearance be-
tween vent pipes and combustible materials
is one (1”) inch (25 mm) on bottom, sides
and top.
Example: According to the chart the maximum
horizontal vent length in a system with a 7.5'
vertical rise is 20' (6 m) and if a 90° elbow is
required in the horizontal vent it must be reduced to
17' (5.2 m). In Figure 20 Dimension A plus B must
not be greater than 17' (5.2 m).

Locate vent opening on the wall. It may be necessary
to first position the fireplace and measure to obtain
hole location. Depending on whether the wall is com-
bustible or noncombustible, cut opening to size. (Fig.

• 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 combustible walls first frame in opening.)
• For each 45° elbow installed in the horizontal run,
the length of the horizontal run MUST be reduced
by 18" (45cm). This does not apply if the 45°
elbows are installed on the vertical part of the vent
system.

Maintenance
Burner and Burner Compartment
FK24/FK12 Fan Assembly
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.
The optional 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.
Always handle the logs with care as they
are fragile and may also be hot if the
fireplace has been in use.
Contact your local representative to arrange an annual
service program.
