familiar with the building codes and installation
techniques appropriate to your area may install
and service this appliance.
The Logsets have been designed and tested to operate safely
when installed according to the installation instructions contained in this manual. Read all instructions before starting the
installation.
In the Commonwealth of Massachusetts, all gas fitting
and installation of this heater shall only be done by a
licensed gas fitter or licensed plumber.
• This appliance is for supplemental heating only, It should
not be used as the primary heat source for a dwelling.
• The vent-free gas logset must be installed only in a fireplace constructed of noncombustible material.
• The logset should be inspected before use and at least
annually thereafter. More frequent cleaning may be necessary
because of excessive lint from carpeting or bedding material.
• In the United States, the installation and operation must
conform to local codes or, in the absence of local codes, with
the National Fuel Gas Code, ANSI Z223.1/NFPA 54, latest
edition, CSA-B149 Installation Code, and with the National
Electrical Code, ANSI/NFPA70 (latest edition).
• The gas logset and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2
p.s.i.g. (3.5 kPa) The gas logset must be isolated from the gas
supply piping system by closing its individual manual shutoff
valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 p.s.i.g. (3.5
kPa)
• Do not, under any circumstances, burn solid fuel (wood,
paper, coal) in the fireplace where you have installed your logset. Do not use it for cooking. Put nothing on top of the logs.
• The logset must be compatible with its fuel. Natural gas
requires different hardware than propane. Never attempt to
use natural gas with a propane logset or vice versa.
• For a propane burning logset, the supply tank must include
a high to low gas pressure regulator. The tank must be outdoors. Do not, under any circumstances, locate supply tanks
inside any structure.
• The fireplace must include a screen made of chain mesh
or a similar material. You must keep the screen closed at all
times during the operation of the logset; it will protect you in
the event of an explosion.
• WARNING: If the fireplace contains glass doors, they must
remain open at all times during the operation of the logset,
allowing combustion air to circulate.
• In order to avoid any possible gas leaks, apply pipe joint
compound to all non-flared threaded connections involved
in this installation. For propane, the joint compound must be
resistant to the corrosive action of propane.
• To check for leaks, always use a soapy water solution or a
sniffer. Never test by using an open flame.
• The area around the gas logset must be free of all combustible materials, especially gasoline or other highly flammable,
vapor producing liquids.

Neither natural gas nor propane gas give off an odor
when burned. The nature of a vent free combustion
system, however, is such that odors may occasionally
be produced during heater operation when impurities
exist in the immediate area. Cleaning solutions, paint,
solvents, cigarette smoke, candles, adhesives, new carpet or textiles, etc., all can create fumes. These fumes
may mix with combustion air and can create odor. Such
odors will disappear over time, however, the condition
can be alleviated by opening a window or otherwise
providing additional ventilation to the area.
High Elevations
Input ratings are shown in BTU per hour and are
certified without deration from elevations up to
4,500 feet (1,370 m) above sea level.
Nuisance outages may occur at altitudes above
4,500 feet (1,370 m) if dirt, dust, lint and/or cobwebs are allowed to accumulate on burner and/or
ODS pilot. Monthly inspection and cleaning is
recommended for altitudes above 4,500 feet
(1,370 m)
For elevations above 4,500 feet (1,370m) 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)

Planning
Planning the installation is an important first step. It will
save time and money later in the actual installation. In
planning the installation, consider:
• Where the heater will be located.
• All components needed to complete the installation.
• DO NOT use this heater in bedrooms, bathrooms,
mobile homes or in recreational vehicles.
• Installation and repair should be done by a qualified
service person.
• DO NOT use this heater if any part has been under
water. Immediately call a qualified technician to inspect
the appliance and replace any part of the control system and any gas control which has been under water.
• When used as an unvented heater, always ensure
that there is adequate ventilation from the room where
the appliance is operating. This appliance is equipped
with an ODS (oxygen depletion sensor) pilot light safety
system designed to shut off the appliance if enough
fresh air is not available.
THIS APPLIANCE MUST NOT BE USED WITH GLASS
DOORS IN CLOSED POSITION.
Keep the burner and control compartment clean. See
installation and operating instructions supplied with the

20002538
Installation Requirements
Fresh Air Requirements for
Combustion and Ventilation
WARNING
This heater must have fresh air for proper operation. If it does not, poor fuel combustion could
result. Read the following instructions to ensure
proper fresh air supply for this and other fuelburning appliances in your home.
Modern construction standards have resulted in homes
that are highly energy-efficient and that allow little heat
loss. Your home needs to breathe, however, and all
fuel-burning appliances need fresh air to function properly and safely. Exhaust fans, clothes dryers, fireplaces
and other fuel burning appliances use the air inside the
building. If the available fresh air supply is insufficient to
meet the demands of these appliances, problems can
result.
The vent-free logsets have specific fresh air requirements. You must determine that these requirements
will be met within the space where the appliance will be
installed. The following information will help you ensure
that adequate fresh air is available for the heater to
function properly.
Provide for Adequate Ventilation
Any space within a home can be classified in these
categories:
1) Unusually tight construction
2) Confined space
3) Unconfined space
First, determine which classification defines the intended installation space.
Unusually Tight Construction
You must provide additional fresh air if the space falls
into this classification. Unusually Tight Construction is
defined as construction wherein:
a. Walls and ceilings exposed to the outside atmosphere have a continuous water vapor barrier with a
rating of one perm or less, with openings gasketed or
sealed, and
b. weather stripping has been added on openable windows and doors and
c. caulking or sealants are applied to areas such as
joints around windows and door frames, between sole
plates and floors, between wall and ceiling joints, between wall panels, at penetrations for plumbing, electrical and gas lines and at all other openings.
If your home meets all of the above criteria, you must
provide additional fresh air for the appliance as detailed
on Page 6.
20002538
Downloaded from www.Manualslib.com manuals search engine
If your home does not meet the above criteria, follow
the procedure below.
Determine If You Have a Confined
or Unconfined Space
Use the following formula to determine if you have a
confined or unconfined space.
Space is defined as the room in which you will install
the heater, plus any adjoining rooms with doorless passageways or ventilation grilles between the rooms.
The National Fuel Gas Code defines a confined space
as a space whose volume is less than 50 cubic feet per
1,000 BTU per hour input rating (4.8m3 per Kw) of the
aggregate (total) input rating of all appliances installed
in that space and an unconfined space as a space
whose volume is not less than 50 cubic feet per 1,000
BTU per hour (4.8m3 per Kw) of the aggregate input
rating of all appliances installed in that space. Rooms
communicating directly with the space in which the appliances are installed, through openings not furnished
with doors, are considered a part of the unconfined
space.
1. Determine the volume of space (length x width x
height). Include adjoining rooms connected by doorless
passageways or ventilating grilles.
Example: A room that is 18’ x 12’ x 8’ has a volume of
1728 cubic feet. An adjoining open kitchen that is 10’
x 12’ x 8’ has a volume of 960 cubic feet. An adjoining
open dining room is 12’ x 12’ x 8’ with a volume of 1152
cubic feet. The total volume is 3840 feet.
2. Divide the volume of space by 50 cubic feet. The
result is the maximum BTU/hour the space can support.
Example: 3840 cubic feet divided by 50 = 76.8 or
76,800 BTU/hour.
3. Add the BTU/hour ratings of all fuel-burning appliances installed in the same space, including the following:
Gas Water Heater
Gas Furnace
Gas Fireplace Logs
Vent-free Gas Heater
Vented Gas Heater*
Other Gas Appliances*
*Do not include Direct-vent appliances as these use
outdoor air for combustion and vent to the outdoors.
Example:
Gas Range
Vent-free Logset
Total
55,000 BTU/hour
+25,000 BTU/hour
80,000 BTU/hour
5
4. Compare the maximum BTU/hour rating the space
can support with the total BTU/hour used by the appliances.
For further information on ventilation guidelines and sizing specifications, follow the National Fuel Gas Code/
NFPA 54/ANSI Z223.1, Section 5.3.
Example: 76,800 BTU/hour the space can support
80,000 BTU/hour used by appliances
If the total BTU/hour used by the appliances is less than
the maximum BTU/hr the space can support, the room
meets the Unconfined Space criteria and no further
ventilation is needed.
In this example, the maximum BTU/hour that the space
can support is less than the total used by the appliances. The space is considered to be Confined Space.
Additional air must be provided to meet the requirements of the vent-free gas log set.
The installation and the provisions for combustion and
ventilation air must conform with the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, or the CSA-B149 Installation Code (Series).
A confined space may be ventilated in two ways:
A. Open or provide at least two ventilating grilles to an
adjoining unconfined space. (Fig. 2)
Each of the two grilles must provide an opening of at
least 50 square inches, with all opening dimensions being at least 3”. One grille must be within 12” of the ceiling; the other within 12” of the floor. (If the total exceeds
100,000 BTU/hour, additional grilles will be needed.)
B. Vent the room directly to the outdoors. (Provide one
square inch of opening for each 4,000 BTU/hour)
WARNING
This heater shall not be installed in a confined
space or unusually tight construction unless
provisions are made for adequate combustion
and ventilation air.
WARNING
If the area in which the heater may be operated
is smaller than that defined as an unconfined
space, or if the building is of unusually tight
construction, provide adequate combustion and
ventilation air by one of the methods described
in the National Fuel Gas Code, ANSI Z223.1/NFPA
54, 1992 Sections 5.3, or applicable codes.
WARNING: Before installing the gas logset in a solidfuel burning fireplace, the chimney flue and firebox must
be cleaned of soot, creosote and loose paint by a qualified chimney cleaner.

Installation Instructions
Installation to Existing Gas Line
There should be a manual ON/OFF valve within easy
reach of the appliance. If not, before installation of the
appliance make certain a valve is installed. There may
be a second valve on the line close to the point where
the fireplace line branches off the main gas supply line.
During installation, make certain this valve is OFF.
Manufactured Fireplace Preparation
Refer to the manufacturer’s fireplace installation manual
for the specific method of running the gas line into the
fireplace. The following method is typical of most manufactured fireplaces.
Insert a 1/2” gas pipe through the gas line tube provided
by the manufacturer, from outside the fireplace, as
marked by the manufacturer. An ON/OFF valve should
be placed within easy reach of the appliance. After the
gas supply is installed, reinstall the insulation removed
from the gas line tube, and pack it around the pipe, to
prevent cold air entry and to protect the gas line. (Fig.

Preparation 11/10/97
A 1/2 inch gas supply line must be supplied to the
firebox. In most cases, this will require drilling a gas line
access hole through the masonry wall. The gas supply
line should then be sealed in the access hole with mortar. The gas supply line should also have a valve within
easy reach of the appliance. Use only N.P.T. black iron
gas line. (Do not use cast-iron pipe.)
Clean the fireplace and chimney (if used) of any ashes,
soot, creosote or obstructions. This will minimize any
smell from the fireplace. We recommend cleaning by a
chimney sweep.
Flue Damper Preparation
The vented fireplace damper should be fully opened
when operating the appliance as a vented log set. A
damper stop clamp with set screw is provided as a
means to prevent full closure of the fireplace damper
blade. The clamp is designed to prevent accidental
closure of the damper when in use. If the damper stop
cannot be installed, a permanent damper stop that will
keep the damper open a minimum of 1¹⁄₂” should be
installed.
NOTE: The gas pipe should not come into contact with
any wood structure until it has reached a point at least
one (1) inch away from the fireplace side. (Fig. 3)

Damper Stop Installation
When installing a decorative gas appliance in a fireplace, some local codes require a damper stop be
added so the damper will not close completely. The
CFM Corporation damper stop is designed so the
damper can be locked in the closed position, and still
allow a vent for the pilot gasses.
Damper Locking Bracket
This damper stop is designed to work on all CFM Corporation BR, BC, TF, TL, SR and SC series fireplaces.
Installation Instructions
Open damper. The damper must be open to attach the
damper stop.
Locate the damper locking bracket. From inside the fireplace locate the damper locking bracket on the left side
of combustion dome. (Fig. 4)

Burner Assembly Location
Centrally locate the unit in the fireplace, far enough
back into the firebox to accomplish adequate draft (if
use as a vented appliance is planned). Ensure the front
grate feet sit inside the front edge of the fireplace a
minimum of 3¹⁄₄”. (Fig. 6b)
Gas Line Connection
Check the gas type. Use only the gas type indicated on
the appliance rating plate. If the gas listed on the plate
is not the type of gas supplied, DO NOT INSTALL the
logset. Contact your dealer for the proper model.
Always use an external regulator for all LP appliances,
to reduce the supply tank pressure to a maximum of
14” w.c. This is in addition to the regulator fitted to the
heater.
CONNECTION TO AN UNREGULATED LP TANK
CAN CAUSE AN EXPLOSION
Connect the appliance to the gas line using fittings and
aluminum tubing provided.
Close the valve knob on the appliance, turn the main
gas supply valve “ON” and carefully check all gas
connections for leaks, with a soapy water solution or a
sniffer.
DO NOT TEST FOR LEAKS WITH AN OPEN FLAME.
On completing your gas line connection, a small
amount of air will be in the gas lines. When first lighting
the pilot, it will take a few minutes for the lines to purge
themselves of air. Once the purging is complete, the
pilot and burner will light and operate as indicated in
this manual. Subsequent lightings of the appliance will
not require purging.
During initial purging and subsequent lightings,
never allow the gas valve control knob to remain
depressed in the ‘PILOT’ position without lighting the pilot with a match or piezo ignitor.
The normal gas connection is made at the right side
(facing unit). If a left-side connection is desired, the connecting pipes may be directed under or behind the rear
of the appliance, to terminate at the right hand side for
connection to the inlet of the appliance.

Check the inlet pressure to the appliance, to ensure that
it is as shown in the table on page 3. The minimum is
for the purpose of input adjustment.
The pressure is controlled by the regulator and should
be checked at the pressure test point located in the
control valve body. Access to the pressure test point is
obtained by removing all logs.
The pressure should be checked with the appliance
burning and the control set on ‘HIGH’.
The pressure is preset and locked to avoid tampering. If
the pressure is not as specified, replace the valve. See
Replacement Parts, page 17.
After measuring the pressure, replace the test point
plug, ensure there are no leaks, then place the logs in
their specified positions.
There is a possibility of odor fade in LP. Never
install an LP appliance or service line below
grade without a gas detector.
Positioning the Logs
The logs must be positioned on the grate and locating
pins as shown in Figures 7-9.
Gas logs must be properly positioned or the appliance
will not function properly and may result in soot accumulation on the inside of the firebox and/or gas logs.
Make sure there is no flame impingement on the logs
which could result in excessive carbon monoxide emissions.
WARNING: Failure to position the parts in accordance with these diagrams or failure to use only
parts specifically approved with this heater may
result in property damage or personal injury.
Carefully position the logs as shown in Figures 7-9.
Make sure each bottom log engages the locator pins on
the grate and top logs are properly positioned in notches on top of the bottom logs.
Clearances
(Refer to Fig. 6, Page 9)
To ensure the safe installation into a masonry or factory
built fireplace, the following instructions must be carefully observed.
1. Sidewall Clearances: The clearance from the inside
of the front opening of the fireplace to any combustible
wall or mantel should not be less than 4¹⁄₂”. (Fig. 6a)
2. Ceiling Clearances: The ceiling height should not be
less than 42” from the top of the fireplace opening.
(Fig. 6a)
3. Mantel Clearances:
WITHOUT HOOD
If no hood is installed then there must be noncombustible material from the top front opening of the fireplace to
a height of at least 20” and the full width of the fireplace.
A combustible flat mantel shelf can be no closer than
38¹⁄₂” from the top front of the opening of the fireplace.
(Fig. 6b)

When Used as a Heating Appliance
1. This appliance is equipped with a modulating valve
which provides variable control of heat output, from
approximately 15,000 or 18,000 BTU/hr at the full
counterclockwise LOW position, to 24,000, 32,000 or
35,000 BTU/hr at the HIGH position, depending on
your appliance. See page 3 for output of your appliance.
2. When used as an unvented heater, maximum benefit
will result when the fireplace flue damper is fully
closed.
3. NOTE: For your safety, the appliance is equipped
with an oxygen depletion sensor. This device senses
the level of oxygen in the atmosphere and switches
off the gas supply in case the level of oxygen falls
below a safe level.
4. The appliance may be used as a heating appliance
only if unvented heating appliances are permitted
by local, state and city codes. In locations that do
not allow unvented heaters, the chimney must have
a permanent chimney opening of not less than 29
square inches.
Maintenance and Safeguards
Keep the control compartment, logs and burner area
around the logs clean by vacuuming or brushing at least
twice a year.
THE LOGS CAN GET VERY HOT. HANDLE ONLY
WHEN COOL.
Always turn off gas to the pilot before cleaning. For
relighting, refer to the lighting instructions.
The appliance and venting system (if used) should be
inspected before initial use and at least annually by a
qualified field service person.
Always keep the appliance area clear and free from
combustible materials, gasoline and other flammable
vapors and liquids.
Never obstruct the flow of combustion and ventilation
air. Keep the front of the appliance clear of all obstacles
and materials.
Leave clearance of at least 36” from the front of the
fireplace.
Although your gas logs are very realistic in appearance,
the fireplace must not be used for burning any solid
fuels.
To avoid irreparable damage to the appliance or personal injury, matches, paper, garbage or any other
material must not be placed or thrown on top of the logs
or into the flames.
To avoid personal injury, do not touch hot surfaces
when the appliance is operating. Touch only the valve
control knob. Avoid contact with the grate feet or
prongs, or any other part which may be very hot.
20002538
Downloaded from www.Manualslib.com manuals search engine
Always ensure that the fireplace screen is closed when
the appliance is operating.
Any safety screen or guard removed for servicing the
appliance must be replaced before operating the appliance.
Close supervision is necessary when the appliance is
being operated near children.
The appliance is intended for use as a gas heater
mounted in a vented or unvented fireplace as described
in the installation sections of these instructions. It
should not be used for any other purpose.
Inspecting the Venting System
A vented fireplace venting system is designed and constructed to develop a positive flow adequate to remove
flue gasses to the outside atmosphere. See vented
fireplace installation instructions.
Any foreign objects in the venting system, except those
designed specifically for the venting system, may cause
spillage of the flue gasses into the room. In extreme
situations, carbon monoxide poisoning or suffocation
may occur.
Periodic examination and cleaning of the venting
system of the solid-fuel burning fireplace must be done
frequently by the home owner or a qualified agency.
VL System Maintenance
The VL burner/control systems consist of:
• Chassis
• Gas Orifice
• Grate Assembly
• VL18 - four (4) decorative gas logs
VL21 - five (5) decorative gas logs
VL24 - six (6) decorative gas logs
• Gas Valve Assembly
• Pressure Regulator
Most of these components require only occasional
checkup and cleaning. Some may require adjustment. If
repair is required, it should be performed by a qualified
technician.
In order to properly clean the burner and pilot assembly,
turn off the gas to the unit, remove the logs exposing
the burner and pilot assembly. Clean all foreign materials from top of burner. Check to make sure that burner
parts are clean. Visually inspect pilot. Brush or blow
away any dust or lint accumulations.
To obtain proper operation, it is imperative that the pilot
and main burner flame characteristics are steady, not
lifting or floating. Refer to Figure 10 for proper main
burner flame appearance and Figure 11 or 12 for proper
pilot flame appearance.
