Installation Considerations - Fireplace Installation Guidelines
Determine where to install the replace insert. The replace
insert can be mounted on any of these surfaces:
1. A at hard combustible or non-combustible surface
2. A raised platform of combustible or non-combustible material
3. Or, install in wood burning replace
If the replace is installed directly on carpeting, tile or other
combustible material other than wood or ooring, it must be
installed on a metal or wood panel extending the full width and
depth of the replace insert.
This replace insert is designed to be installed in a zero-clearance
enclosure. This means combustible material such as framing
lumber can come in contact with the top and side standoff
spacers, and be secured to combustible framing.
This replace insert requires an easily accessible gas shut-off
valve be installed in the gas supply line prior to its entry to the
replace.
Determine the following before installation:
• Any desired accessories
• Gas supply piping
• Electrical connections
• Electrical supply requirements for blower
(120V, 60Hz, 1Amp) (Right entrance)
A selection of a shut-off valve containing a ange and key is
recommended.

could result in death or serious injury.
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
trafc 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 ammable material on or near the
appliance.
• Avoid the use of scented air fresheners (plug in type air
fresheners, etc. ) while the burner is in operation. Air fresheners
produce a residue in the air similar to candles and may produce
a soot like substance.
• Avoid the use of scented or decorative candles while the
burner is in operation. Candles produce a residue in the air that
creates a soot like substance. Burning candles while the log
set is operating magnies 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 qualied 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 insert with decorative front installed.
• Do not place debris, logs or other articles in replace insert
during operation.
• During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain oils, lms
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.
• WARNING: Do not allow fans to blow directly into the
replace. Avoid any drafts that alter burner ame patterns.
• WARNING: Do not use a blower insert, heat exchanger insert
or other accessory not approved for use with this heater.
• WARNING! This replace needs fresh air for ventilation
to run properly. This replace 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 place large rocks or embers (rock wool)
in replace insert.
• 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 ammable vapors and liquids.
• 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 writ-
ten 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 u,
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 inuence 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 ow is not directed at
the burner.

SAFETY INFORMATION FOR USERS OF PROPANE GAS
Propane is a ammable gas which can cause res and explo-
sions. 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.
PROPANE GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas
because of the odorant put in the Propane 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.
• Propane 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
reghters declare them to be safe.
• Use your neighbor's phone and call a trained Propane Gas
service person and the re 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 reghters check for escaped
gas. Have them air out the area before you return. Properly
trained Propane 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 nd 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 Propane 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 lter the odorant.
Odorants in Propane 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. Propane 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 Propane Gas. Your local
Propane Gas Dealer can give you a "Scratch and Sniff" pam-
phlet. Use it to nd out what the propane odor smells like. If
you suspect that your Propane Gas has a weak or abnormal
odor, call your Propane Gas Dealer.
• If you are not qualied, do not light pilot lights, perform service,
or make adjustments to appliances on the Propane Gas system.
If you are qualied, consciously think about the odor of Propane
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 Propane 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 Propane 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 lled and allowed to set too
long before relling. Cylinders and tanks which have been out
of service for a time may develop internal rust which will 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 Propane Gas Dealer. Aperi-
odic sniff test of the Propane Gas is a good safety measure
under any condition.
• Sooting: A vent-free replace or burner draws room air to
support combustion. Lightweight particles suspended in the air –
including dust, carpet bers, candle or tobacco smoke, and pet
hair – will be drawn toward the replace. These can lead to soot
build up on logs, replace walls, and even walls of the room. To
prevent malfunctions and sooting, have your dealer perform an
inspection and cleaning each year – before the heating season.
If you have pets or excessive dust, more frequent cleaning may
be necessary. See cleaning and service section in this manual.
• Place embers (rock wool) in this replace, as shown on
pages 24 and 26.
• Do not place lava rocks on burner or logs.
• Installing a television above a replace has become a
desirable feature; however, the following information should
be considered.
All replaces, whether decorative or heater rated create
heat. Most television manufacturers recommend not placing
a television near a heat source. Because there is a large
variety of television manufactures, styles and sizes, it is
impractical to test every potential installation. If you choose to
install a television above or near your replace, understand
that Empire Comfort Systems accepts no responsibility for
this decision and any injury or damage due to this application
is the sole responsibility of the owner. Additionally, it is highly
recommended to turn off the replace and let it cool down
before servicing or using the operational buttons located
on the television. In all cases, the television manufacturer’s
instructions and warnings should be followed.
IMPORTANT SAFETY INFORMATION (CONT'D)

43165-1-1221 Page 7
SAFETY INFORMATION FOR USERS OF PROPANE GAS (CONT'D)
• If, at any time, you do not smell the Propane 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 Propane 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 orices. 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 relled before it is completely empty.
PROPER LOG PLACEMENT
Log placement is critical to proper burner performance. Logs must
be correctly positioned onto the burner. The photos in this manual
show the proper pinned position for logs on this set. Owners need to
be shown proper log placement and instructed not to move the logs.
Logs must t rmly onto the burner when positioned as shown in
the photos. Malformed logs or logs with sloppy pin holes must be
replaced.
PROPER PLACEMENT OF ROCK WOOL AND
DECORATIVE LAVA ROCK
Rock wool can be added to burners for a glowing ember effect.
It must be positioned only on the front portion of the burner. The
photos in this manual show the proper placement of rock wool.
Decorative lava rock or small wood pieces should never be placed
on the burner. These items are only for placement on the oor of
the replace or rebox.
PROPER PRIMARY AIRFLOW INTO BURNER
For proper burner operation and ame appearance, the ow of
primary air into the venturi tube, located on the rear of the burner,
must not be reduced. This ow of air is reduced if dirt, lint or other
obstructions build-up around or inside the venturi. Any obstruction
in the venturi tube area must be removed. The ow of air into the
venturi is also reduced if the gas orice isn’t centered in the venturi
inlet and/or is not aligned with the venturi. Any misalignment of the
burner orice may be corrected by bending the shutter cap holding
the orice to the inlet of the venturi tube.
CEILING FANS, PORTABLE FANS OR LOGS
INSTALLED NEAR COLD AIR RETURNS
Ceiling fans or oscillating oor type fans need to be monitored
during the operation of vent-free logs. If the air blows directly
into the ame causing it to impinge on the log set, or rebox, it
should be turned off or redirected. Ceiling fans could be reversed
to possibly eliminate ame impingement, and the oor fan could
be redirected. Upon installation, be aware of any cold air returns
or vents in the proximity of the log set. Any draft created around
a vent-free log set can cause the ame to impinge on the log and
create a sooting situation.
WARNING
Do not allow fans to blow directly into the replace. Avoid
any drafts that alter burner ame patterns.
WARNING
Do not use a blower insert, heat exchanger insert or other
accessory not approved for use with this heater.
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
magnies 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.
MAKE OWNERS AWARE OF PROPER LOG SET OPERATION
Properly installed and properly maintained log sets do not deposit
soot on the logs. If users see soot appear on a log, call for service.
Do not continue to operate the log set.
This appliance is only for use with the type of gas indicated on
the rating plate and may be installed in an aftermarket, perma-
nently located, manufactured (mobile) home where not prohib-
ited by local codes. This appliance is not convertible for use with
other gases.
CAUTION
Do not operate the appliance with panel(s) removed,
cracked or broken. Replacement of the panel(s) should be
done by a licensed or qualied service person.
WARNING
Improper installation, adjustment, alteration, service or
maintenance can cause property damage, personal injury
or loss of life. Installation and service must be performed
by a qualied installer, service agency or the gas supplier.

Standard Z21.11.2-2016 as an Unvented Room Heater and should
be installed according to these instructions.
Any alteration of the original design, installed other than as
shown in these instructions or use with a type of gas not

VFPC28IN3 and VFPC20IN3 Series Only
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 ame 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 energy) to build-up to a
sufcient level allowing the gas control to operate properly.
Important
All correspondence should refer to complete Model Number, Serial
Number and type of gas.
NOTICE: During initial ring of this unit, its paint will bake out, and
smoke will occur. To prevent triggering of smoke alarms, ventilate
the room in which the unit is installed.

1. First check to make sure there is no hidden damage to the
unit. Take a minute and plan out the gas and electrical route. It
is best to start with the gas line rst, followed by the electrical
supply requirements.
2. Minimum replace opening requirements are shown in
Figure 2 of this installation manual. The rebrick (refractory),
glass doors, screen rails, screen mesh and log grates can be
removed from a replace in order to gain minimum gas insert
opening requirements prior to installing the gas replace insert.
CAUTION
Determine the total thickness of nishing materials (i.e.
stone, brick or marble) so that the proper dimensions can be
maintained for installing the replace and decorative fronts.
3. Although the insert does not require a hearth extension, only
heat resistant materials such as stone, metal, tile, etc. should
be used. Do not use vinyl, carpet, or wood based products
within 16 inches of the insert face. Do not obstruct the lower
vented openings on the insert. NOTE: The original replace
cannot be returned to solid fuel use without returning the hearth
extension to the specication required for a solid fuel replace.
4. The side walls, top and oor structures of the rebox may not
be altered with the exception of removable bafes and damp-
ers. Smoke shields, shelves and bafes may be removed.
The original replace cannot be returned to solid fuel in this
condition.
5. The insert surround is tested and approved with this gas in-
sert and may cover existing air circulation vents or grills on the
solid fuel replace it is installed into. If the surround does not
cover the entire ventilation grill surface, the exposed grill area
should be left open.
NOTICE: Cutting any sheet-metal from the decommissioned re-
place or rebox for the installation of zero-clearance unvented re-
place insert, may be necessary and is acceptable in this application.
NOTICE: The following statement is also provided on a separate
label plate in the instruction packet. Prior to installation of the re-
place insert, the installer must mechanically secure this warning
plate to the inside of the replace for future reference as required.
WARNING
The solid fuel replace has been converted for use with gas
only and cannot be used for burning wood or solid fuels un-
less all original parts have been replaced and the replace
has been reapproved by the authority having jurisdiction.
Positioning, Leveling and Securing Insert
6. Place the insert into position.
NOTICE: The front anges of the insert (without surround panels)
should be set at approximately 1" in front of the face of the replace.
7. Level the insert from side to side and front to back.
8. If necessary, use the leveling bolts included in the instruction
pack. Screw the legs into the nuts installed in the bottom of
the insert. Turn legs in until insert is level.
NOTICE: The best way to access the leveling bolt locations
is to remove the burner and rebox bottom.
NOTICE: If desired, it is acceptable to attach metal strapping
or brackets (not provided) from the replace cavity to the insert
outer jacket to secure the replace insert to the replace hearth
or opening.
9. Install the insert without the surround panels attached and
make all gas venting and electrical connections. If the control
module, receiver and other electrical devices are pulled out to
install the gas line, they must be placed back into the location
where they were from the factory. The gas exline may cross
over the control module.
WARNING
Verty that all wire connections are secure.
If the factory built replace does not have gas access holes
provided, an access hole of 1 1/2” diameter (37.5mm) or
less may be drilled through the lower sides or bottom of
the rebox in a proper workmanship like manner. This ac-
cess hole must be plugged with a non-combustible insula-
tion after the gas supply line has been installed.
10. The surround panel assembly is attached to the replace after
it has been installed with all the gas and electrical connections
completed. Refer to instructions included with the surround
panel kit.
