IMPORTANT:
PLEASE REVIEW 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 CFM Harris Systems 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.

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 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
diagram and chart.
Noncombustible mantels and legs may be installed at
any height and width around the appliance. When
using paint or lacquer to finish the mantel, such paint
or lacquer must be heat resistant to prevent
discoloration.

Framing and Finishing
1. Choose the unit location.
2. Place the unit into position and secure it to the floor
with 1¹⁄₂” (38mm) screws, or nails. The holes to
secure the unit to the floor are located just behind
the access door grille on the left and right side of the
unit.
3. Frame in the fireplace with a header across the top.
It is important to allow for the finished wall face when
setting the depth of the frame.
4. Attach the fireplace to the frame using the adjustable
frame drywall strips (located behind the access door
for shipping). Preset the depth to suit the facing
material of the wall. The strips are adjustable to 1/2”
(13mm), 5/8” (16mm), or 3/4” (19mm). (Figs. 3 & 4)
5. Screw through the slotted holes in the drywall strip
and into the pre-drilled holes in the fireplace side.
Measure from the face of the fireplace to the face of
the drywall strip to confirm the final depth.

Gas Line Installation
When purging gas lines, the front window frame assembly must be removed.
The gas pipeline can be brought in through the rear of
the appliance 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 consult your
local authority and the National Fuel Gas Code, ANSI
Z223.1 in the USA or the CSA-B149.1 installation
code.

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 the gas line can be easily disconnected for burner or fan servicing. 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
and any other gas appliance control from the gas line
when pressure testing.

General Information on Assembling DV Components
Crimped End Pipes
Before joining elbows and pipes apply a bead of high
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.
Canadian Installations:
Venting system must be installed in accordance with
the current CSA-B149.1 installation code.
USA Installations:
The venting system must conform with local codes
and/or the current National Fuel Gas code ANSI
Z223.1.
Only venting components manufactured by CFM
Corporation can be used in Direct Vent systems.

Pyromaster© H33BDVRRN/P
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 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
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. 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.
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).

Rear Wall Vent Applications
NOTE: It is not necessary to seal the vent pipe
joints for any straight out of the wall rear vent
applications.
NOTE: Vent Starter Kit Model 7TDVSK or 7DVSK
