•
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 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 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.

•
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: 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 Propane GAS
Propane 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.
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
firefighters declare them to be safe.
• Use your neighbor's phone and call a trained Propane 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 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 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 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 filter 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" pamphlet. Use
it to find 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.
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. A periodic sniff test of the propane
gas is a good safety measure under any condition.
• If you are not qualified, do not light pilot lights, perform service,
or make adjustments to appliances on the Propane Gas system.
If you are qualified, consciously think about the odor of Propane
Gas prior to and while lighting pilot lights or performing service
or making adjustments.
• 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.
• 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 filled and allowed to set too long before
refilling. Cylinders and tanks which have been out of service for
27357-15-0719
• 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.

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).

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.
A confined space is an area with volume less than 50 cubic feet per
1,000 Btuh of the combined input rates of all appliances drawing
combustion air from that space. Small areas such as equipment
rooms are confined spaces. Furnaces installed in a confined space
which supply heated air to areas outside the space must draw return
air from outside the space through tightly sealed return air ducts. A
confined space must have 2 openings into the space for combustion air. One opening must be within 12 inches of the ceiling and
the other must be within 12 inches of the floor. The required sizing
of these openings is determined by whether inside or outside air is
used to support combustion, the method by which the air is brought
to the space (vertical or horizontal duct) and by the total input rate
of all appliances in the 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. Weather-stripping 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 additional fresh 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, Air for
Combustion and Ventilation, or applicable local codes.

•
•
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.
BOTTOM BASE ASSEMBLY
(VIEW OF UNDERSIDE)
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 appliance to the fireplace floor.
If not, the entire unit may move when you adjust the
controls. Movement of unit may cause shifting of the
optional decorative glass. Burner 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 controls. This will insure adequate air
flow and guard against sooting. Raise the fireplace floor
using noncombustible materials.
Installation of Burner Support Legs
Four (4) Burner Support Legs are included with the Loft Burner.
Installation is optional if you have a VFRU (millivolt series burner.
•
If a Remote Control option is to be used with the VFRU
(millivolt) series burner without the Support Legs installed,
the remote receiver box must be installed outside of the
firebox away from excessive heat. However, the remote
receiver may be placed under the elevated Loft Burner by
installing the (4) Burner Support Legs. See Figure 11.
If the Support Legs are to be installed, simply bend each
of the (4) legs into a "U" shape to match the drawing in
Figure 12. Next, install the legs into the bottom base. Line up
the three tabs on each leg with the slots provided, using pliers
twist each of the tabs slightly in order to secure the legs to the
bottom base.
•
Installation of the Burner Support Legs is necessary on the
VFIU (remote ignition) series burners. These models include
a remote receiver box that must be placed under the bottom
base of the Loft Burner assembly to shield the receiver
batteries from excessive heat. See Figure 16.
To install the Support Legs, simply bend each of the (4) legs
into a "U" shape to match the drawing in Figure 12. Next, install

NOTICE: Never use plastic pipe. Check to confirm whether your
local codes allow copper tubing or galvanized.
NOTICE: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
NOTICE: The gas line may be routed from either side of the firebox
and connected to the gas inlet on the gas valve.
Installing a New Main Gas Shut-Off
Each appliance should have its own manual gas shut-off.
A manual main gas shut-off 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.
NOTICE: Check inlet and outlet fittings on gas valve for leaks, but
do not expose electronic components to the solution. Exposing
them to the solution may damage the components.
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.
27357-15-0719
Figure 13
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 Commonwealth 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).
CAUTION
If the gas pressure exceeds the maximum limits listed on page
8 of this manual or on the installed gas valve, it will result in a
hazardous condition.
Page 17
OPERATION INSTRUCTIONS
Flames from the pilot (near the center of the burner) as well as the
main flame should be visually checked as the burner assembly is
installed and initially operated.
In normal operation at full rate, the flame appearance should be
random yellow flames above the burner.
NOTICE: all flames will be random by design, flame height will go
up and down.
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 will 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.
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.
To remove top cover to gain access to gas valve for hookup of gas
line and burner securement, remove three (3) #8 x 1/2" screws
from both front flanges at the lower front of the burner assembly,
then lift the top cover upward.

WIRING - VFRU MODELS
Thermostats are not approved on vented decorative
appliances.
NOTICE: Do not let remote control receiver come in contact with
the top of the appliance.
Label all wires prior to disconnection when servicing controls. Wiring
errors can cause improper and dangerous operation. Verify proper
operation after servicing.
Refer to remote control installation and operating instructions for
more details on remote control.
On a circulating vent-free firebox, it may be possible to install the
remote control receiver behind the bottom operable louver.
The gas appliance (Millivolt) thermopile self powers the gas valve
and does not require 110 volts. See Figure 15 to provide optional
wall switch, thermostat, or remote control. Maximum length of 20
feet of 16 AWG conductor wires should be used with all optional
switches.
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.
Check System Operation
Millivolt system and all individual components may be checked with
a millivolt meter 0-1000 MV range.
Remote Receiver
Use the following steps to place the remote receiver to the burner
base assembly.
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.
Attention:
1. The remote receiver can not be placed behind or inside the gas
burner assembly. The remote receiver should be located outside
of the firebox.
2. The remote receiver can be placed under the burner assembly in
a lower air moving compartment of a fireplace or firebox, installed
in a wall mounted junction box, or set on the hearth extension.

PILOT FLAME CHARACTERISTICS
Figures 22 and 23 show a correct pilot flame pattern. The correct
flame will be blue and will extend beyond the thermocouple. The
flame will surround the thermocouple just below the tip. A slight
yellow flame may occur where the pilot flame and main burner flame
meet. Figures 24 and 25 show an incorrect pilot flame pattern.
The incorrect pilot flame is not touching the thermocouple. This will
cause the thermocouple to cool. When the thermocouple cools, the
heater will shut down.
