operating this fireplace again.
5. Installation and any repairs to this fireplace must be
performed by a qualified installer, service agency or gas
supplier. A professional service person should be con-
tacted to inspect this fireplace annually. Make it a practice
to have all of your gas fireplaces checked annually. More
frequent cleaning may be required due to excess lint and
dust from carpeting, bedding material, etc.
6. Control compartments, burners and air passages in this
fireplace should be kept clean and free of dust and lint.
Make sure the gas valve and pilot light are turned off
before you attempt to clean this fireplace.
7. The venting system (chimney) of this fireplace should be
checked at least once a year and if needed your venting
system should be cleaned.

cated on the rating plate. This appliance is not
convertible for use with other gases, unless a certified
kit is used.
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 CFM Specialty Home Products
company 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
optional fan kit has been installed, place the fan switch
in the “OFF” position during this time.
Locating Your Fireplace

Final Finishing
Gas Line Installation
Noncombustible materials such as brick or tile can be
extended over the edges of the face of the fireplace. Do
not cover the window frame assembly, any vent,
louvre assembly top or louvre assembly bottom. If a
Trim Kit is to be installed, brick and tile will have to be
installed flush with the side of this appliance.
When purging gas line the front glass
must be removed.
The gas pipeline can be brought in through the right
side of the appliance. Knockouts are provided at
convenient locations to allow for the gas pipe installa-
tion and testing of any gas connection.
The gas line connection can be made with properly
tinned 3/8" copper tubing, 1/2" 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 CSA-B149.1 installation codes.
For USA installations consult the current National Fuel
Gas Code, ANSI Z223.1/NFPA 54.

Alternate Switch Location
Always check for gas leaks with a mild
soap and water solution applied with a
brush no larger than 1” (25mm). Never
apply soap and water solution with a
spray bottle. Do not use an open flame
for leak testing.
The remote switch can be installed on either side of the
access door. Mount the switch to the switch bracket
provided. Screw the bracket on either side of the
frame, line up the screws with the prepunched holes.
(Fig. 8)
The fireplace valve must not be sub-
jected 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 ap-
proved fittings. Always provide a union when using
black iron pipe so that the gas line can be easily
disconnected for burner or fan servicing. (Fig. 6) See
the gas specifications for pressure details and ratings.

• Venting terminals shall not be recessed into a wall or
siding.
Location of Vent Termination
• Horizontal venting which incorporates the twist lock
pipe must be installed on a level plane without an
inclining or declining slope.
• Horizontal venting which incorporates the use of flex
venting shall have an inclining slope from the unit of
1/2” (13mm) per 12” (305mm).
It is imperative the vent termination be located observ-
ing the minimum clearances as shown on following
page.

Twist Lock Pipes
When using 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 twist lock 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
contacts external flange on the male end. It is recom-
mended that you secure the joints with three (3) sheet
metal screws, however, this is not mandatory with twist
lock pipe. (Fig. 17)
To make it easier to assembly 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
Fig. 18 Sidewall venting graph. (Dimensions in feet.)
The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the
relationship between the vertical and horizontal dimen-
sions fo the vent system.
Refer to Page 19 for venting
requirements for snorkels.
Rear Wall Vent Application
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. 17),
locate the point intersecting with the slanted graph
line.
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
approved 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)
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’
(3.4m) the horizontal run to the face of the outer wall
must not exceed 14’ (4.3m).
• Only one 45° elbow is allowed in these installations.
EXAMPLE B:
• Minimum clearances between vent pipe and com-
If the vertical dimension from the floor of the unit is 7’
(2.1m), the horizontal run to the face of the outer wall
must not exceed 8¹⁄₂’ (2.6m).

Locate and cut the vent opening in the wall. For com-
bustible walls first frame in opening. (Fig. 21)
Adjustable Zero Clearance Sleeve
ZCS101
NOTE: When using flex vent, the opening will have to
be measured according to the 1/2” (13mm) rise in 12”
(305mm) vertical run.
Fig. 22 Adjustable zero clearance sleeve.
Step 4
Combustible Walls: Cut a 10³⁄₈”H x 9³⁄₈” W (265mm x
240mm) hole through the exterior wall and frame as
shown. (Fig. 21)
Install the 4” (102mm) vent to the appliance collar and
secure with 3 sheet metal screws. Install the 7”
(178mm) vent pipe to the appliance collar and secure
with 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.
Noncombustible Walls: Hole opening should be 7¹⁄₂”
(191mm) diameter.
Zero clearance sleeve is only required for
combustible walls.
It is critical that there is no downward
slope away from the appliance when
connecting the vent or elbow.
Step 2
Measure wall thickness and cut zero clearance sleeve
parts to proper length (Maximum 12” / 305mm). As-
semble sleeve to its maximum opening (10³⁄₈” x 9³ ₈”)
and attach to firestop assembly. (Fig. 22)
Step 5
Guide the venting through the vent hole as you place
the appliance in its installed position. Guide the 4”
(102mm) and 7” (178mm) 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.
Step 3
Measure the horizontal length requirement for the
venting including a 2” (51mm) overlap, i.e. from the
elbow to the outside wall face plus 2” (51mm). (Fig. 20)

Rear Wall Vent Installations -
Flex Vent Pipe
The Vent Graph, showing the relationship between
vertical and horizontal side wall venting, will help to
determine the various dimensions allowable.
Follow Steps 1 and 2 on Page 14.
Step 3
Install the 4” (102mm) flex vent pipe to the appliance
collars described in “General Information Assembling
Vent Pipes”, Page 12. If the installation requires a 45°
angle, grasp the vent pipe close to the appliance collar
and bend to 45°. DO NOT exceed 45°. (Fig. 24)
Minimum clearance between vent pipes and com-
bustible materials is 1” (25mm) 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.
Install the 7” vent pipe in the same manner as Step 2.
It is best to locate the fireplace in such a way that
minimizes the number of offsets and horizontal vent
length.
Termination
Flex Section
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.
Appliance Collars
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.
FP1473
Fig. 24 Grasp the vent pipe close to the collar and bend to
45° angle. Do not exceed 45°.
NOTE: There must be a 1/2” (13mm) rise in a 12”

Apply high temperature sealant to 4” (102mm) and 7”
(178mm) collars or the termination one inch away from
crimped end. Guide the vent terminations 4” and 7”
collard into their respective vent pipes. Double check
that the vent pipes overlap the collars by 2” (51mm).
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 ap-
proved 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” (152mm)
beyond the outer face of the wall.
Install the 4” (102mm) flex vent pipe to the appliance
collar as described on Page 12. Secure the end with
the first spring 6³⁄₄” (172mm) from the flex pipe end to

Do not back fill around snorkel.
Below Grade Installation
A clearance of at least 4” must be main-
tained between the snorkel and the soil.
When it is not possible to meet the required vent
terminal clearances of 12” (305mm) above grade level,
a snorkel kit is recommended. It allows installation
depth down to 7” (178mm) below grade level. The 7”
(178mm) is measured from the center of the horizontal
vent pipe as it penetrates through the wall.
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 the
protruding wall face. (Fig. 38)
Ensure the sidewall venting clearances are ob-
served. If venting system is installed below ground,
we recommend a window well with adequate and
proper drainage to be installed around the termina-
tion area.
If installing a snorkel, a minimum 24” (610mm) vertical
rise is necessary. The maximum horizontal run with the
24” vertical pipe is 36” (914mm). 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 verti-
cal exceeds 24” (610mm).

It is necessary to clean the glass periodically. During
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 the glass be cleaned two
or three times with a non-ammonia household cleaner
and warm water (gas fireplace glass cleaner is
recommended). After the initial cleaning process the
glass should be cleaned two or three times during each
operating season depending on the environment in the

Trouble Shooting the Gas Control System
SIT NOVA 820 Millivolt Valve
Note: Before trouble shooting the gas control system, be sure external gas shut off is in the “On” position.
WARNING: Before doing any gas control service work, remove glass front.
SYMPTOM
POSSIBLE CAUSES
CORRECTIVE ACTION
1.Spark ignitor will not light
A. Defective or misaligned
electrode at pilot.
Using a match, light pilot. If pilot lights, turn off
pilot and push the red button again. If pilot will not
light - check gap at electrode and pilot-should be
1/8" to have a strong spark.
B. Defective ignitor (Push Button)
Push Piezo Ignitor Button. Check for spark at
electrode and pilot. If no spark to pilot, and elec
trode wire is properly connected, replace ignitor.
2.Pilot will not stay lit after
carefully following lighting
instructions.
A. Defective pilot generator
(thermocouple), remote wall
switch.
Check pilot flame. Must impinge on thermo
couple/thermopile. Note: this pilot burner assem
bly utilizes both-a thermocouple and a thermopile.
The thermocouple operates the main valve
operation (On and Off). Clean and or adjust pilot for
maximum flame impingement on thermopile and
thermocouple.
B. Defective automatic valve
Turn valve knob to “Pilot”. Maintain flow to pilot;
milivolt meter should read greater than 10 mV. If
the reading is okay and the pilot does not stay on,
replace the gas valve. Note: An interrupter block
(not supplied) must be used to conduct this test.
3.Pilot burning, no gas to
main burner
A. Wall switch or wires defective
Check wall switch and wires for proper connec
tions. Jumper wire accross terminals at wall
switch, if burner comes on, replace defective wall
switch. If okay, jumper wires across wall switch
wires at valve, if burner comes on, wires are faulty
or connections are bad.
B. Thermopile may not be
generating sufficient
millivoltage.
1. Be sure wire connections from thermopile at
gas valve terminals are tight and thermopile is
fully inserted into pilot bracket.
2. One of the wall switch wires may be grounded.
Remove wall switch wires from valve terminals if
pilot now stays lit, trace wall switch wiring for
ground. May be grounded to fireplace or gas
supply.
3. Check thermopile with millivolt meter. Take
reading at thermopile terminals of gas valve.
Should read 250-300 millivolts (minimum 150)
while holding valve knob depressed in pilot
position and wall switch “Off”. Replace faulty
thermopile if reading is below specified minimum.
C. Plugged burner orifice.
Check burner orifices for debris and remove.
D. Defective automatic valve
operator.
Turn valve knob to “On”, place wall switch to “On”
millivolt meter should read greater than 100 mV. If
the reading is okay and the burner does not come
on, replace the gas valve.
4.Frequent pilot outage
problem.
A. Pilot flame may be too low
or blowing (high) causing the
pilot safety to drop out.
Clean and/or adjust pilot flame for maximum flame
impingement on thermopile and thermocouple.
B. Possible blockage of the vent
terminal.
Check the vent terminal for blockage (recycling the
flue gases)

To obtain proper operation, it is imperative that the pilot
Burner and Burner Compartment
and burner’s flame characteristics are steady, not lifting
or floating.
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.
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.
Always handle the logs with care as they
are fragile and may also be hot if the
fireplace has been in use.
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 techni-
cian.
