General Information
In order to assure a safe and effective installation, only a qualified service person who is
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.
• The vent-free gas logset must be installed only in a
fireplace constructed of noncombustible material.
• These logsets are not for exterior use.
• This appliance is for supplemental heating only. It should
not be used as the primary heat source for a dwelling.
• The logset should be inspected before use and at least
annually thereafter. More frequent cleaning may be
necessary due to 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-B149.1 Installation Code, and with the
National Electrical Code, ANSI/NFPA70 (latest edition).
State or local codes may only allow operation of this
appliance in a vented configuratio. Check your state or
local codes. In Canada, check local province for proper
use or CSA-B149. Refer to pages 7 and 8 for installation
details.
• 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.
• Due to high temperatures, locate this logset away from
both high traffic areas and furniture and draperies.
• Children and adults alike should be aware of the high
surface temperatures; to avoid the risk of burns or ignition
of clothing they should stay away.
• Do not touch any part of the logset other than the
controls while it is operating or immediately after you turn
it off.
• Supervise young children and pets carefully when they
are in the room where the logset is operating.
• Do not place clothing or other flammable material on or
near the logset.
• Make sure that any safety screen or guard, removed
during servicing, has been replaced before you use the
logset.
• Do not, under any circumstances, install the logset in
any bedroom, bathroom, other small, enclosed room,
mobile home or recreational vehicle.
• Do not install the logset in a drafty area or use it with any
after-market blower system that may cause drafting and
consequently alter the flame pattern.
• It is imperative that you keep clear all burner areas,
control compartments and passageways for circulating air.
• Do not move the logset in any way that might dislodge
the logs from their fixed positions. If you bump the logset
check to see if you have dislodged anything.
• Provide adequate clearances around air openings into
the combustion chamber and adequate accessibility
clearance for servicing and proper operation. NEVER
obstruct the front opening of the fireplace.
• Avoid propane tank dropping below 25% full. This will
help keep soot from occurring.

Odor During Operation
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 (1,370m) above sea level.
Nuisance outages may occur at altitudes above
4,500 feet (1,370m) 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 (1,370m)
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

installation and operating instructions supplied with the
heater.
WARNING: During manufacturing, fabricating and
shipping, various components of this appliance are
treated with certain oils, films or bonding agents.
These chemicals are not harmful, but may produce
annoying smoke and smells as they are burned off
during the initial operation of the appliance, possibly
causing headaches or eye or lung irritation. This is a
normal and temporary occurrence. The initial break-in
operation should last 2-3 hours with the burner at its
highest setting. Provide maximum ventilation by
opening windows, doors and the chimney flue to
allow odors to dissipate. Any odors remaining after
this initial break-in will be slight and will disappear
with continued use.
This appliance operates as an unvented domestic room
heater when fitted to a masonry or factory-built woodburning fireplace with the flue damper closed, or as a
decorative appliance when the flue damper is fully open. It
must not be used for any other purpose and must be fitted

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 fuel-burning 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 all 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.
struction
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,
b. weather stripping has been added on openable
windows and doors
c. caulking or sealants are applied to areas such as
joints around windows and door frames, between

If your home meets all of the above criteria, you
must provide additional fresh air for the appliance as
detailed on Page 6.
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 (4.8m
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:
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
cubic feet.
2. Divide the volume of space by 50 cubic feet. The
result is the maximum BTU/hour the space can
support.
Example:
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 HeaterGas Furnace
Gas Fireplace LogsVent-free Gas Heater
Vented Gas Heater*Other Gas Appliances*
* Do not include Direct-vent appliances as these use

Example:
Gas Range 55,000 BTU/hour
Vent-Free LogSet+
25,000 BTU/hour
Total 80,000 BTU/hour
4. Compare the maximum BTU/hour rating the space
can support with the total BTU/hour used by the
appliances.
Example:76,800 BTU/hour the space can support
80,000 BTU/hour used by appliances
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 on 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 CSAB149.1 Installation Code (Series).
A confined space may be ventilated in two ways:
A. Open up 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/hr.)
For further information on ventilation guidelines and
sizing specifications, follow the National Fuel Gas
Code/NFPA 54/ANSI Z223.1/NFPA 54, Section 5.3.
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.
WARNING
This heater shall not be installed in a confined
space or unusually tight construciton 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 log set in a
solid-fuel burning fireplace, the chimney flue and
firebox must be cleaned of soot, creosote, and loose
paint by a qualified chimney cleaner.

Installation Instructions
WARNING
Do not allow fans to blow directly into the
fireplace. Avoid any drafts that alter burner
flame patterns.
WARNING: Do not use a blower insert, heat
exchanger insert, or other accessory not
approved for use with this gas logset.
DO NOT burn solid fuels in a fireplace where
an unvented gas room heater or logset is
installed.
Any outside air ducts and/or ashdumps in the
fireplace must be permanently closed at time
of appliance installation.
Preparing the Fireplace
Gas Line Preparation
Before connecting the appliance, turn off all gas
appliances. Close the main gas valve at the gas
meter or appliances. Close the main gas valve at the
gas meter or LP tank. Make certain there is good
ventilation where the installation will be made.
Installation should comply with all applicable building
codes and ANSI Z223.1/NFPA 54, latest edition, or
CSA B-149.1. Use LP gas-resistant pipe compound
to seal threaded joints.
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. 3)
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)
Do not install this appliance in bedrooms or
bathrooms.
WARNING: Any change to this heater or its
controls can be dangerous.

Masonry Fireplace Installation
Preparation
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
1/2” rigid pipe or approved 3/8” copper tubing. (Do
not use cast-iron pipe).
Clean the fireplace and chimney (if used) of any
ashes, soot, creosote, or obstruction. 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. (Fig. 4) (If the
damper stop cannot be installed, the installer should
install a permanent damper stop that will keep the
damper open a minimum of 1¹⁄₂”).
UVL Series

Page 8
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.
This damper stop is designed to work on all CFM
Specialty Home Products BR, BC, SR, SC, TF and
TL series fireplaces.
Installation Instructions
1. Open damper. The damper must be open to
attach the damper stop.
2. Locate the damper locking bracket. From inside
the fireplace locate the damper locking bracket on
the left side of the combustion dome. (Fig. 4)
3. Align the two slots on either side of the cutout on
the damper stop with the two small holes on the
angled portion of the damper locking bracket.
Attach the damper stop with the screws provided.
(Fig. 5)
NOTE: Some of the early units may not have the
holes in the end of the damper locking bracket. If this
is the case use the damper stop as a template to drill
two (2) 1/8” holes in the damper locking bracket to
mount the damper stop.

2. Ceiling Clearances: The ceiling height should not
be less than 42” from the top of the fireplace opening.
(Fig. 7A)
3. Mantel Clearances:
When installing an ANSI Z21.11.2 ventless appliance, the finishing material used for the mantel must
be rated at 250°F or greater. Refer to firebox instructions for any further information.
Without hood:
If no hood is installed, then there
must be non-combustible material from the top front
opening of the fireplace to a height of at least 20
inches 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 fireplace opening (Fig. 7B).
With hood:
If a hood is installed there must be noncombustible material from the top front opening of
the fireplace to a height of 7¹⁄₂” and the full width of
the fireplace. A combustible flat mantel shelf may be
installed according to the detail in Figure 7C.

Gas Line Connection
WARNING
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.
The normal gas connection is made at the right side
(facing the unit). If a left-side connection is desired,
the connecting pipe may be directed under or behind
the rear of the appliance, to terminate at the righthand side for connection to the inlet of the appliance.
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.
Upon 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.
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.
(UVL-M
series only)
The pressure should be checked with the appliance
burning and the control set on ‘HIGH’.
The pressure regulator is preset and locked to avoid
tampering. If the pressure is not as specified,
replace the regulator. Refer to Replacement Parts.
After measuring the pressure, replace the test point
plug. Ensure there are no leaks, then place the logs
in their specified positions.
Connection directly to an unregulated LP tank
can cause an explosion.
During the 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.
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 Figure 8. Make sure each
bottom log engages the locator pins on the grate,
and top logs are properly positioned in notches on
tops of bottom logs.
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
on the gas logs. Make sure there is no yellow
flame impingement on the logs which could

The First Firing
On completing the gas line connection, a small
amount of air will be trapped in the gas line. When
you first light the unit with the pilot light, it will take a
few minutes to purge the trapped air. Once you have
purged the gas line, the pilot and burner will light and
operate normally. Subsequent lightings of the
appliance will not require purging the gas line.
When lit for the first time, the appliance will emit a
slight odor for an hour or two. This is due to paint
and lubricants used in the manufacturing process
curing under heat. This is normal. You may wish to
have the windows open to dissipate any odors
during the curing process.

Maintenance and Safeguards
Keep the control compartment, logs and burner area
around the logs clean by vacuuming or brushing at
least twice a year. At altitudes above 4,500 feet
(1370m) monthly cleaning is recommended.
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.
Always ensure that the fireplace screen is closed
when the appliance is operating.
Any safety screen or guard removed for servicing the
appliances 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 section 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 gases 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.
UVL System Maintenance
The UVL burner and control system consists of:
• Chassis
• Gas Orifice
• Grate assembly
• UVL18 - four (4) decorative logs
UVL24 - five (5) decorative logs
UVL30 - seven (7) decorative logs
• Gas valve assembly
• Pressure regulator (UVL18M and UVL24M only)
Most of these components require only occasional
check-up and cleaning. Some may require adjustment. If repair is needed, 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 and remove the
logs, exposing the burner and pilot assembly. Clean
all foreign materials from the top of the burner.
Check to make sure that all burner parts are clean.
Visually inspect the pilot. Brush or blow away any
dust or lint accumulations.
NOTE: The burner and pilot assembly should be
checked for any dust or lint at least every six
months.
