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.

Input ratings are shown in BTU per hour and are
certified without deration for elevations up to
4,500 feet (1,370 m) above sea level.
For elevations above 4,500 feet (1,370 m) 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 (1,370 m).
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 consult your
local authority and the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 in the USA or the CSA-B149.1 installation codes.
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.
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.

Canadian Installations:
General Information on Assembling Vent Pipes
The 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/
NFPA 54.
Only venting components manufactured by CFM Corporation can be used in Direct Vent systems.
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 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 horizon
tal vent pipe exiting through the outer wall. Using
this dimension on the Sidewall Vent Graph (Fig. 8),
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’ (3.4m) 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’
(2.14m), 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” (508 mm) 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.

and horizontal dimensions for a Direct Vent flue system.
• The maximum number of 90° elbows per side wall
Vertical dimension from the floor of the fireplace to
installations is three (3).
• For RFSDV24 and RFSDV34 models, the maximum
the center of the horizontal vent pipe
horizontal rn for a minimum 12” (305 mm) vertical
rise is 3’ (914 mm). (Fig. 9)
Fig. 9 Maximum horizontal run.
• 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. 10)
This does not apply if the 90° elbows are used to
increase or redirect a vertical rise. (Fig. 11)
horizontal vent length is 20’ (6 m). However, if a
90° elbow is used in the horizontal vent, maximum
horizontal vent length is reduced to 17’ (5.2 m).
In Figure 9, the total of Dim. A and Dim. B must not
exceed 17’ (5.2 m).
• The maximum number of 45° elbows permitted per
installation is six (6). 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. 12)
1 + 2 + 3 + 4 = 270°

Below Grade Installations
When it is not possible to meet the required vent terminal clearances of 12” (305 mm) above grade level a
snorkel vent kit is recommended. It allows installation
depth of down to 7” (178 mm) 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).
1. Establish vent hole through the wall. (Fig. 13)
2. Remove soil to a depth of approximately 16”
(406 mm) below base of snorkel. Install drain pipe.
Install window well (not supplied). Refill hole with 12”
(305 mm) of coarse gravel leaving a clearance of
approximately 4” (102 mm) below snorkel. (Fig. 20)
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 to maintain a 4” (102 mm) clearance
below snorkel. (Fig. 20)
Fig. 19 Horizontal length to wall.
Support horizontal pipes every 3’ (914 mm)
with metal pipe straps.
Check fireplace to make sure it is leveled

If the foundation is recessed, use recess brackets (not
supplied) for securing lower portion of the snorkel.
Fasten brackets to wall first, then secure to snorkel
with self drilling #8 x 1/2 sheet metal screws. It will be
necessary to extend vent pipes out as far as protruding
wall face. (Fig. 21)
• Vertical installations up to 40’ (12 m) 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.
• Up to two 45° elbows may be used within the
horizontal run. For each 45° elbow used on the
horizontal level the maximum horizontal length must
be reduced by 18” (457 mm).
Example: Maximum horizontal length
0 x 45° elbows = 10’ (3 m)
1 x 45° elbows = 8¹⁄₂’ (2.6 m)
2 x 45° elbows = 7’ (2.1 m)
• A minimum of an 8’ (2.4 m) vertical rise.
• Two sets of 45° elbows offsets within these vertical
installations. From 0 to a maximum of 8’ (2.4 m) of
vent pipe can be used between elbows. (Fig. 22)
• 7DVCS must be used to support offsets. (Fig. 22)

(2 per side)
FP1517
Fig. 26 Window frame removal.
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.

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.
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 18, Figure
30)
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.
Cleaning the Standing
Pilot Control System
The burner and control system consist of:
• burner tube • 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.
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.
