IMPORTANT:

PLEASE READ 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 gas fireplace to give off some odor
the first time it is burned. This is due to 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 op
tional fan kit has been installed, place the fan switch in
the “OFF” position during this time.

also applies to the distance between the mantel leg (if
fitted) and the fireplace.

For the correct mounting height and widths, refer to
Figures 4a and 4b and the Mantel Chart below.

The distances and reference points are not affected by
the fitting of a bay window front trim kit.

Hearth

A hearth is not mandatory but is recommended for
aesthetic purposes. We recommend a noncombustible
hearth which projects out 12” (305 mm) or more from
the front of the fireplace.

Cold climate installation recommendation:

When installing this unit against a non­insulated exterior wall or chase, it is
mandatory that the outer walls be insulated
to conform to applicable insulation codes.

Framing and Finishing

Check fireplace to make sure it is levelled
and properly positioned.

NOTE: If the optional Metro Face Kit (DVBR36 only)
is to be installed, the fireplace may be placed on a
4” (102 mm) raised platform. Raising the fireplace
will give the best aestethic appearance but is not
required.

To mount the appliance:

1. Choose the location.

2. Nailing flanges are supplied with the fireplace (found

on the fireplace hearth). To level the box and secure
it firmly in place, remove the nailing flanges from
the hearth and install at the sides of the fireplace as
shown in Figure 5.

Always check for gas leaks with a mild
soap and water solution applied with a
brush no larger than 1” (25 mm). Never
apply 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 when using black
iron pipe so the gas line can be easily disconnected for
burner or fan servicing. (Fig. 6) See the gas specifica­tions for pressure details and ratings.

Remote Switch Installation

Do not wire the remote ON/OFF wall switch

for this gas appliance into a 120v power

supply.

EB-1 Electrical Box

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.

For USA installations, follow the local
codes and the national Electrical Code
ANSI/NFPA No. 70.

It is strongly suggested that the wiring of
the EB-1 Electrical Junction Box be carried
out by a licensed electrician.

Ensure that the power to the supply line
has been disconnected before commenc-

ing this procedure.

EB1 (Receptacle) Hook-Up

1. Remove contents from plastic bag. Remove knock­out in center of electrical box. Remove coverplate
from fireplace and knockout. Insert connector

When using CFM Corporation twist-lock pipe, it is not
necessary 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 termination connection (when necessary). The
female (flared) end secures to the fireplace first with the
male end away from the fireplace.

To join the pipes together, simply align the beads of the
male end with the grooves of the female end, twisting
the pipe until the flange on the female end touches the
external bead on the male end. Secure the joints with
three (3) sheet metal screws. (Fig. 17)

To make assembly easier, apply lubricant (vaseline or
similar) on the male end of the twist-lock pipe.

How to Use the Vent Graph

The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the
relationship between the vertical and horizontal dimen­sions to 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. 18),
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 unit is 11
feet (3352 mm) the horizontal run to the face of the
outer wall must not exceed 14’ (4267 mm).

EXAMPLE B:

If the vertical dimension from the floor of the unit is 7’
(2133mm), the horizontal run to the face of the outer
wall must not exceed 8¹⁄₂’ (2590 mm).

Rear Wall Vent Applications

When installed as a rear vent unit this appliance may be
vented directly to a termination located on the rear wall
behind the appliance.

• Only CFM Corporation venting components are ap-

proved to be used in these applications (See ‘Venting
Components’ listed for different installation require­ments).

• The maximum horizontal distance between the rear

of the appliance (or end of the transition elbow in a
corner application) and the outside face of the rear
wall is 20” (508mm). (Fig. 19, 20 )

• Only one 45° elbow is allowed in these installations.

• Minimum clearances between vent pipe and com-

bustible materials are as follows:

Top - 2” (51 mm)
Sides - 1” (25 mm)
Bottom - 1” (25 mm)

Step 1

Locate and cut the vent opening in the wall.
For combustible walls first frame in opening. (Fig. 21)

NOTE: When using flex vent, the opening will have to
be measured according to the 1” (25 mm) rise in 24”
(610 mm) vertical run.

Combustible Walls:

Cut a 10³⁄₈”H x 9³⁄₈” W (265 mm
x 240 mm) hole through the exterior wall and frame as
shown. (Fig. 21)

Noncombustible Walls:

Hole opening should be 7¹⁄₂”

(191 mm) diameter.

Zero clearance sleeve is only required for
combustible walls.

Step 2

Measure wall thickness and cut zero clearance sleeve
parts to proper length (Maximum 12” / 305mm). As­semble sleeve to its maximum opening (10³⁄₈” x 9³₈”)
and attach to firestop assembly. (Fig. 22)

Step 3

Measure the horizontal length requirement for the vent­ing including a 2” (51 mm) overlap, i.e. from the elbow
to the outside wall face plus 2” (51 mm). (Fig. 20)

Step 4

Install the 4” (102 mm) vent to the appliance collar and
secure with three (3) sheet metal screws. Install the 7”
(175 mm) vent pipe to the appliance collar and secure
with three (3) sheet metal screws. It is not necessary to
seal this connection. If a 45° elbow is being used attach
the elbow to the appliance in the same manner then at­tach the venting to the elbow.

It is critical that there is no downward
slope away from the appliance when con­necting the vent or elbow.

Step 5

Guide the venting through the vent hole as you place
the appliance in its installed position. Guide the 4”
(102 mm) and 7” (175 mm) collar of the vent termina­tion into the outer ends of the venting. Do not force
the termination. If the vent pipes do not align with the
termination, remove and realign the venting at the appli­ance flue collars. (Fig. 23) Attach the termination to the
wall as outlined in the instruction sheet supplied with
the termination.

NOTE: There must be a 1” (25 mm) rise in 24”

(610 mm) length of flex vent.

Step 4

Assemble the flex vent to the collars on the termination
as you did on the appliance.

FP1472

Fig. 25 There must be a 1” rise in 24” length.

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 ver
tical and horizontal side wall venting, will help to deter­mine the various dimensions allowable.

Minimum clearance between vent pipes and com­bustible materials is 1” (25 mm) on top, bottom and
sides unless otherwise noted.

When vent termination exits through foundations less
than 20” (508mm) below siding outcrop, the vent pipe
must flush up with the siding.

It is best to locate the fireplace in such a way that mini
mizes 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 (or the top of
the Transition Elbow) to the face of the outer wall.

Horizontal plane means no vertical rise exists on this
portion of the vent assembly.

When installing the appliance as a rear
vent unit, the 90° or 45° Transition Elbow
attached directly to the rear of the unit is
NOT INCLUDED in the following criteria
and calculations, and unless specifically
mentioned should be ignored when calcu­lating venting layouts.

• The maximum number of 90° elbows per side wall

installation is three (3). (Fig. 26)

• If a 90° elbow is fitted directly on top of the fireplace

flange the maximum horizontal vent run before the
termination or a vertical rise is 36” (914mm). (Fig.

27)

• If a 90° elbow is used in the horizontal vent run

(level height maintained) the horizontal vent length
is reduced by 36” (914mm). (Fig. 28, 29) This does
not apply if the 90° elbows are used to increase or
redirect a vertical rise. (Fig. 26)

Example: According to the vent graph (Page 15) the
maximum horizontal vent length in a system with a
7¹⁄₂” (191mm) rise is 20” (508mm) and if a 90° elbow is
required in the horizontal vent it must be reduced to 17’

• 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” (457mm). 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

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. 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” vent pipe, however for this method, you must extend
the 4” pipe approximately 6” (152 mm) beyond the outer
face of the wall.

Below Grade Installation

When it is not possible to meet the required vent terminal
clearances of 12” (305 mm) above grade level, a snorkel
kit is recommended. It allows installation depth down
to 7” (178 mm) below grade level. The 7” (178 mm) is
measured from the center of the horizontal vent pipe as it
penetrates through the wall.

Ensure the sidewall venting clearances are ob­served. If venting system is installed below ground,
we recommend a window well with adequate and
proper drainage to be installed around the termina­tion area.

If installing a snorkel, a minimum 24” (610 mm) vertical
rise is necessary. The maximum horizontal run with the
24” 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. See the Sidewall
Venting Graph for extended horizontal run if the vertical
exceeds 24” (610 mm).

1. Establish vent hole through the wall (Fig. 31)

2. Remove soil to a depth of approximately 16”
(406mm) below base of snorkel. Install drain pipe.
Install window well (not supplied). Refill hole with 12”
(305mm) of coarse gravel leaving a clearance of ap­proximately 4” (102 mm) below snorkel. (Fig. 37)

3. Install vent system.

4. Ensure a watertight seal is made around the vent
pipe coming through the wall.

5. Apply high temperature sealant caulking (supplied)
around the 4” and 7” snorkel collars.

6. Slide the snorkel into the vent pipes and secure to
the wall.

7. Level the soil so as to maintain a 4” (102 mm) clear
ance below snorkel. (Fig. 37)

Vertical Through-the-Roof Applications

This gas fireplace has been approved for:

• Vertical installations up to 40’ (12m) in height. Up

to a 10’ (3 m) horizontal vent run can be installed
within the vent system using a maximum of two 90°
elbows. (Fig. 41)

• Up to two 45° elbows may be used within the hori-

zontal run. For each 45° elbow used on the horizon­tal plane, the maximum horizontal length must be
reduced by 18” (450mm).

Example: Maximum horizontal length:
No elbows = 10’ (3 m)

1 x 45° elbow = 8.5’ (2.6 m)
2 x 45° elbows = 7’ (2.1 m)

• A minimum of an 8’ (2.5 m) vertical rise is required.

• Two sets of 45° elbow offsets may be used within the

vertical sections. From 0 to a maximum of 8’ (2.5 m)

Inspecting the Venting System

This appliance venting system was 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 glass frame
(See Glass Frame Removal Section). Using
a flashlight, check the area above the baffle
in the combustion dome. Clean if necessary.

Maintenance

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 replace 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.

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.

Contact your local representative to arrange an annual
service program.

Cleaning the Standing

Pilot Control System

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” or 1/2” of the thermopile should
be engulfed in the pilot flame. (Fig. 71)

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.
