IMPORTANT SAFETY INFORMATION
DANGER: Indicates a hazardous situation which, if not avoided, will
result in death or serious injury.
WARNING: Indicates a hazardous situation which, if not avoided,
could result in death or serious injury.
•
WARNING! This fireplace needs fresh air for ventilation to
run properly. This fireplace has an ODS (oxygen depletion
sensor) which will shut down the heater if adequate fresh air is
not available. See troubleshooting section in the instructions.
•
WARNING: DO NOT operate this appliance unless all
components including logs, burners, and controls are in good
working condition. Never operate this appliance if any log or
twig is broken, or out of their intended position. Refer to the
Log set placement instructions for correct log and twig
positioning.
Replacement components are available through your local
dealer as indicated in the How to Order Repair Parts section of
the appliance manual.
Keep appliance area clear and free from combustible materials,
gasoline and other flammable vapors and liquids.
CAUTION: Indicates a hazardous situation which, if not avoided,
could result in minor or moderate injury.
NOTICE: Addresses practices not related to personal injury.
•
An unvented room heater having an input rating of more than
6,000 Btu per hour shall not be installed in a bathroom
•
An unvented room heater having an input rating of more than 10,000
Btu per hour shall not be installed in a bedroom or bathroom.
•
Due to high temperatures, the appliance should be located out of
traffic and away from furniture and draperies.
•
Children and adults should be alerted to the hazard of high surface
temperature and should stay away to avoid burns or clothing
ignition.
•
Young children should be carefully supervised when they are in
the same room with the appliance.
•
Do not place clothing or other flammable material on or near the
appliance.
• Avoid the use of scented air fresheners (plug in type air
fresheners, etc. ) while the log set is in operation. Air fresheners
produce a residue in the air similar to candles.
• Avoid the use of scented or decorative candles while the log
set is in operation. Candles produce a residue in the air that
creates a soot like substance. Burning candles while the log
set is operating magnifies the problem. It should be noted that
candles, in general, produce soot. The amount of time burned
and the quantity of candles burned will determine the amount
of soot produced and deposited.
•
Installation and repair should be done by a QUALIFIED SERVICE
PERSON. This appliance should be inspected before use and at
least annually by a professional service person. More frequent
cleaning may be required due to excessive lint from carpeting,
bedding materials, etc. It is imperative that control compartments,
burners and circulating air passageways of the appliance be
kept clean.
•
DO NOT use this room heater if any part has been under water.
Immediately call a qualified service technician to inspect the
room heater and to replace any part of the control system and
any gas control which has been under water.
•
You must operate heater with fireplace screen in place.
•
Do not place trash, logs or other articles on the log set during
operation.
• During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain oils, films
or bonding agents. These bonding agents are not harmful but
may produce annoying smoke and smells as they are burned
off during initial operation of the appliance. This is a normal
temporary occurrence. A window should be opened during the
initial bake out period.
•
Correct installation of the ceramic fiber logs, proper location of
the heater and annual cleaning are necessary to avoid potential
problems with sooting. Sooting, resulting from improper
installation or operation, can settle on surfaces outside the
fireplace. See instructions for proper installation.
•
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 heater.
27829-2-0614
•
•
WARNING: Failure to keep the primary air opening(s) of the
burner(s) clean may result in sooting and property damage.
WARNING
When used without adequate combustion and ventilation air,
heater may give off CARBON MONOXIDE, an odorless, poisonous gas.
Do not install heater until all necessary provisions are
made for combustion and ventilation air. Consult the written instructions provided with the heater for information
concerning combustion and ventilation air. In the absence
of instructions, refer to the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and Ventilation, or
applicable local codes.
This heater is equipped with a PILOT LIGHT SAFETY SYSTEM designed to turn off the heater if not enough fresh air
is available.
DO NOT TAMPER WITH PILOT LIGHT SAFETY SYSTEM!
If heater shuts off, do not relight until you provide fresh air.
If heater keeps shutting off, have it serviced. Keep burner and
control compartment clean.
CARBON MONOXIDE POISONING MAY LEAD TO DEATH.
Early signs of carbon monoxide poisoning resemble the flu,
with headache, dizziness and/or nausea. If you have these
signs, heater may not be working properly. Get fresh air at
once! Have heater serviced.
Some people — pregnant women, persons with heart or lung
disease, anemia, those under the influence of alcohol , those
at high altitudes — are more affected by carbon monoxide
than others.
The pilot light safety system senses the depletion of oxygen
at its location. If this heater is installed in a structure having a
high vertical dimension, the possibility exists that the oxygen
supply at the higher levels will be less than that at the heater.
In this type of application, a fan to circulate the structure air will
minimize this effect. The use of this fan will also improve the
comfort level in the structure. When a fan is used to circulate
air, it should be located so that the air flow is not directed at
the burner.

SAFETY INFORMATION FOR USERS OF LP-GAS
Propane (LP-Gas) is a flammable gas which can cause fires
and explosions. In its natural state, propane is odorless
and colorless. You may not know all the following safety
precautions which can protect both you and your family from
an accident. Read them carefully now, then review them point
by point with the members of your household. Someday when
there may not be a minute to lose, everyone's safety will depend
on knowing exactly what to do. If, after reading the following
information, you feel you still need more information, please
contact your gas supplier.
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!
•
•
•
•
•
Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
Get everyone out of the building, vehicle, trailer, or area. Do
that IMMEDIATELY.
Close all gas tank or cylinder supply valves.
LP-Gas is heavier than air and may settle in low areas such
as basements. When you have reason to suspect a gas leak,
keep out of basements and other low areas. Stay out until
firefighters declare them to be safe.
Use your neighbor's phone and call a trained LP-Gas service
•
person and the fire department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
Finally, let the service man and firefighters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must find out if you
can smell the odorant in propane. Smoking can decrease your
ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors in
the area mask the gas odor. People may not smell the gas odor
or their minds are on something else. Thinking about smelling a
gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can filter the odorant. Odorants
in LP-Gas also are subject to oxidation. This fading can occur if
there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into walls,
masonry and other materials and fabrics in a room. That will take
some of the odorant out of the gas, reducing its odor intensity.
LP-Gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels. Always be sensitive to the slightest gas
odor. If you detect any odor, treat it as a serious leak. Immediately
go into action as instructed earlier.
SOME POINTS TO REMEMBER
•
Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it to
find out what the propane odor smells like. If you suspect that
your LP-Gas has a weak or abnormal odor, call your LP-Gas
Dealer.
•
If you are not qualified, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. If you are qualified, consciously think about the
odor of LP-Gas prior to and while lighting pilot lights or performing service or making adjustments.
•
Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-Gas odor. Do not try to light
pilot lights, perform service, or make adjustments in an area
where the conditions are such that you may not detect the
odor if there has been a leak of LP-Gas.
•
Odor fade, due to oxidation by rust or adsorption on walls of
new cylinders and tanks, is possible. Therefore, people should
be particularly alert and careful when new tanks or cylinders
are placed in service. Odor fade can occur in new tanks, or
reinstalled old tanks, if they are filled and allowed to set too
long before refilling. Cylinders and tanks which have been
out of service for a time may develop internal rust which will
Page 4
cause odor fade. If such conditions are suspected to exist,
a periodic sniff test of the gas is advisable. If you have any
question about the gas odor, call your LP-gas dealer. A
periodic sniff test of the LP-gas is a good safety measure
under any condition.
•
If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
•
If you experience a complete "gas out," (the container is
under no vapor pressure), turn the tank valve off immediately.
If the container valve is left on, the container may draw in
some air through openings such as pilot light orifices. If this
occurs, some new internal rusting could occur. If the valve is
left open, then treat the container as a new tank. Always be
sure your container is under vapor pressure by turning it off
at the container before it goes completely empty or having it
refilled before it is completely empty.

GENERAL INFORMATION
This is an unvented gas-fired heater. It uses air (oxygen) from the
room in which it is installed. Provisions for adequate combustion
and ventilation air must be provided.
Keep room area clear and free from combustible materials, gasoline
and other flammable vapors and liquids.
Unvented gas heaters are a supplemental zone heater. They are not
intended to be a primary heating appliance. Water vapor produced
by an unvented heater can create moisture problems in a home
when operated for extended periods of time.
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 the highest setting. Provide maximum ventilation by opening
windows or doors to allow odors to dissipate. Any odors remaining
after this initial break-in period will be slight and will disappear with
continued use.
This appliance must not be used with glass doors in the closed
position. This can lead to pilot outages and severe sooting outside
the fireplace.
Do not use this room heater if any part has been under water.
Immediately call a qualified service technician to inspect the room
heater and replace any part of the control system and any gas
control which has been under water.
WARNING
This appliance is equipped for (natural or propane) gas. Field
conversion is not permitted.
Before you get started
Carefully inspect the contents for shipping damage. If any parts are
missing or damaged, immediately inform the dealer from whom you
purchased the appliance. Do not attempt to install any part of the
appliance unless you have all parts in good condition.
Make sure you have received all parts:
Check your packing list to verify that all listed parts have been
received. You should have the following:
• Gas log grate/burner assembly.
• Two (2) masonry anchoring screws and two (2) 10 x 1/2" black
sheet metal anchoring screws.
• Plastic bag containing glowing embers (rock wool) for burner
coverage.
• Plastic bag containing lava rock.
• Switch log assembly - VFSR models
Millivolt controlled heater designed to be operated with optional
devices for ON/OFF functions.
• Wall switch or thermostat with wire.
• Hand held remote control with ON/OFF switch or thermostat.
Handle the gas log burner assembly by the grate and legs only.
Do not pick the unit up by the burner.
Gloves are recommended when handling logs to prevent skin
irritation. Logs are fragile - Handle with care.
Qualified Installing Agency
Installation and replacement of gas piping, gas utilization equipment or accessories and repair and servicing of equipment shall be
performed only by a qualified agency. The term "qualified agency"
means any individual, firm, corporation, or company that either in
person or through a representative is engaged in and is responsible for (a) the installation, testing, or replacement of gas piping
or (b) the connection, installation, testing, repair, or servicing of
equipment; that is experienced in such work; that is familiar with all
precautions required, and that has complied with all the
requirements of the authority having jurisdiction.
State of Massachusetts: The installation must be made
by a licensed plumber or gas fitter in the Commonwealth of
Massachusetts.
Sellers of unvented propane or natural gas-fired supplemental
room heaters shall provide to each purchaser a copy of 527
CMR-30 upon sale of the unit.
The installation must conform with local codes or, in the absence of
local codes, with the National Fuel Gas Code, ANSI Z223.1.*
*Available from the American National Standards Institute, Inc. 11
West 42nd St., New York, N.Y. 10018.
High Altitudes: For altitudes/elevation above 2,000 feet ratings
should be reduced at the rate of 4 percent for each 1,000 feet above
sea level. Contact the manufacturer.
WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An unvented room
heater produces approximately one (1) ounce (30ml) of water for
every 1,000 BTU's (.3KW's) of gas input per hour.
Unvented room heaters must be used as supplemental heat (a
room) rather than a primary heat source (an entire house). In most
supplemental heat applications, the water vapor does not create a
problem. In most applications, the water vapor enhances the low
humidity atmosphere experienced during cold weather.
Page 8
The following steps will help insure that water vapor does not
become a problem.
1. Be sure the heater is sized properly for the application, including
ample combustion air and circulation air.
2. If high humidity is experienced, a dehumidifier may be used to
help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat source
(an entire house).
27829-2-0614
PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR
This heater shall not be installed in a confined space unless provisions
are provided for adequate combustion and ventilation air.
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 (4.8m3
per kw) of the aggregate 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 (4.8 m3 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.
Unusually Tight Construction
The air that leaks around doors and windows may provide enough fresh
air for combustion and ventilation. However, in buildings of unusually
tight construction, you must provide additional fresh air.
Unusually tight construction is defined as construction
where:
a. Walls and ceilings exposed to the outside atmosphere have a
continuous water vapor retarder with a rating of one perm or
less with openings gasketed or sealed, and
b. Weatherstripping has been added on openable windows and
doors, and
c. Caulking or sealants are applied to areas such as joints around
window and door frames, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for
plumbing, electrical, and gas lines, and at other openings.
If your home meets all of the three criteria above, you must provide

INSTALLING AS A VENTED APPLIANCE
Notice: (Damper Clamp Installation)
When installing your log set as a vented installation the
damper clamp must be used.
When installing your log set as a vent-free installation the
damper clamp can be used to eliminate the potential for odors
when burning the logs for the first time.
Installing Damper Clamp
Remove all ashes or other debris from the fireplace. If the
fireplace is equipped with an ash dump be sure to seal the
door with furnace cement or high temperature silicone. Be
sure to check the damper for proper operation and verify that
the flue passageway is open.
Place the clamp over the lip of the damper and tighten the
hold down bolt until the clamp is securely attached to the
damper. This will prevent the damper from accidentally
closing.
Manual and millivolt controlled gas logs may be installed as
a vented decorative log set in compliance with ANSI Z21.60
and National Fuel Gas Code. When the gas logs are operated with the damper open, non-combustible material and
minimum mantel requirements do not apply.
Figure 9
BEFORE FULLY INSTALLING THE APPLIANCE
•
•
Turn off the gas supply to the fireplace or firebox.
Seal any fresh air vents and/or ash clean-out doors
located on the floor or wall of the fireplace. If left unsealed, drafting may cause pilot outage or sooting. Use
a heat resistant sealant. Do not seal the chimney flue
damper.
Before installing in a solid fuel burning fireplace, the chimney
flue and firebox must be cleaned of soot, creosote, ashes
and loose paint by a qualified chimney cleaner.
You must secure the gas log heater to the fireplace
floor. If not, the entire unit may move when you adjust
the controls. Movement of unit may cause shifting
of the gas logs which leads to sooting and improper
burning. Grate movement could cause a gas leak.
Special care is required if you are installing the unit
into a sunken fireplace. You must raise the fireplace
floor to allow access to gas log controls. This will
insure adequate air flow and guard against sooting.
Raise the fireplace floor using noncombustible
materials.
Assembly Procedure:
1. Center the gas log unit in the fireplace or firebox. Make
certain the front feet of the grate sit inside the front edge
of the fireplace or firebox.
2. An anchor hole is provided in the two bottom side members of the grate frame. After centering the grate correctly,
mark the hole positions on the fireplace/firebox floor.
Drill two (2) 5/32" diameter holes approximately 1-1/2"
deep for masonry screws or 1/8" hole for sheet metal
screws.
3. Anchor the grate to the fireplace/firebox floor using the
screws provided. Refer to Figure 10.
Proper installation of the grate is essential to prevent any
movement of the gas logs and controls during operation.

Notice: Since some municipalities have additional local
codes, it is always best to consult your local authority and
installation code.
Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of
the unit. Where none exists, or where its size or location is not
adequate, contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be
resistant to the action of liquefied petroleum gases. The gas
lines must be checked for leaks by the installer. This should
be done with a soap solution watching for bubbles on all
exposed connections, and if unexposed, a pressure test
should be made.
Never use an exposed flame to check for leaks. Appliance must be disconnected from piping at inlet of control
valve and pipe capped or plugged for pressure test.
Never pressure test with appliance connected; control
valve will sustain damage!
A gas valve and ground joint union should be installed in the
gas line upstream of the gas control to aid in servicing. It is
required by the National Fuel Gas Code that a drip line be
installed near the gas inlet. This should consist of a vertical
length of pipe tee connected into the gas line that is capped
on the bottom in which condensation and foreign particles
may collect.
27829-2-0614
Figure 11
The use of the following gas connectors is recommended:
— ANS Z21.24 Appliance Connectors of Corrugated Metal
Tubing and Fittings
— ANS Z21.45 Assembled Flexible Appliance Connectors
of Other Than All-Metal Construction
The above connectors may be used if acceptable by the
authority having jurisdiction. The state of Massachusetts
requires that a flexible appliance connector cannot exceed
three feet in length.
Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8"
(3.175mm) N.P.T. plugged tapping, accessible for test
gauge connection, must be placed immediately upstream
of the gas supply connection to the appliance.
2. The appliance 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 psig (3.5 kPa).
3. The appliance 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 psig
(3.5 kPa).
Attention! If one of the procedures results in pressures in
excess of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas
valve, it will result in a hazardous condition.
Page 13
PLACEMENT OF GLOWING EMBERS AND LAVA ROCK
Placement of the glowing embers (rock wool) is very individual and light coverage will provide your best effects. We
recommend separation of the rock wool by hand and make
your coverage as light and fluffy as possible.
Place just enough embers on the burner to obtain the glow
and a gold, yellow flame.
Do not place embers (rock wool) over large ports in rear
portion of burner.
Rock wool should not be placed in the area of the pilot assembly.
Replacement of loose material (glowing embers) must be
purchased from Empire Comfort Systems, Inc. Application
of excess loose material (glowing embers) may adversely
affect performance of the heater.
Refer to Parts List, Page 22 to order loose material (rock
wool).
Placing Lava Rock in Front of Burner on Fireplace
Floor
Spread lava rocks on fireplace floor in front of the burner pan.
The lava rocks are for decorative effect and are not required
for fireplace operation.
ATTENTION: DO NOT PLACE LAVA ROCKS ON
BURNER, LOGS OR ROCK WOOL. THE LAVA ROCKS
SHOULD ONLY BE PLACED ON THE FIREPLACE
FLOOR.
WARNING: All previously applied loose material must be
removed prior to reapplication.
OPERATION INSTRUCTIONS/FLAME APPEARANCE
Flames from the pilot (rear right back side of the pan burner)
as well as the main flame should be visually checked as the
log set is installed.
In normal operation at full rate after 10 to 15 minutes, the
flame appearance should be sets of yellow flames.
Notice: All flames will be random by design, flame height will
go up and down.
Glowing embers (rock wool) can cover the pan burner in
between the front and middle logs, but very little is necessary
to cover this area. Excess ember material causes the yellow
flame to become orange and stringy. Apply just enough to
obtain slow glow and a gold yellow flame.
Millivolt - Figure 12
Avoid any drafts that alter burner flame patterns. Do not
allow fans to blow directly into fireplace. Do not place a
blower inside the burner area of the firebox. Ceiling fans may
create drafts that alter flame patterns. Sooting and improper
burning will result.
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.
Manual - Figure 13
The initial break-in operation should last 2-3 hours with the
burner at the highest setting. Provide maximum ventilation
by opening windows or doors to allow odors to dissipate. Any
odors remaining after this initial break-in will be slight and
will disappear with continued use.

Millivolt system and all individual components may be checked with
a millivolt meter 0-1000 MV range.
Remote Receiver -VFSR-(16, 18, 24, 30)
Use the following steps to place the remote receiver adjacent to
the gas valve.
Attention:
1. The remote receiver can not be placed behind the gas valve
and burner assembly.
2. When facing the appliance, the remote receiver must be placed
to the right of the gas valve and burner assembly.
Notice: Do not let remote control receiver come in contact with
burner assembly.
On circulating vent-free firebox, install remote control receiver
behind bottom louver.
Refer to remote control installation and operating instructions for
more details on remote control.
750 Millivolt System
When you ignite the pilot, the thermocouple produces millivolts
(electrical current) which energizes the magnet in the gas valve.
After 30 seconds to 1 minute time period you can release the gas
control knob and the pilot will stay ON. Allow your pilot flame to
operate an additional one (1) to two (2) minutes before you turn the
gas control knob from the PILOT position to the ON position. This
time period allows the millivolts (electrical current) to buildup to a
sufficient level allowing the gas control to operate properly.

Millivolt Control
The valve regulator controls the burner pressure which should be
checked at the pressure test point. Turn captured screw counter
clockwise 2 or 3 turns and then place tubing to pressure gauge over
test point (Use test point “A” closest to control knob). After taking
pressure reading, be sure and turn captured screw clockwise firmly
to re-seal. Do not over torque. Check for gas leaks.

assembly. When connecting to remote receiver, cut off 1/4" terminals
from wires attached to ON/OFF switch. Strip wires back about 1/4".
