Warning: Thisheaterishotwhile
inoperation. Do nottouch. Keep
children, clothing and furniture
away. Never operate this heater
without the factory-installed
dress guard in place. Never use
this heater to dry clothes, cook
on,or forany otherpurpose other
than providing heat to the area
around the heater.
Notice: The heater will go
through a curing process during
its initial (first 2 to 3 hours)
operating period and may emit
somesmoke and fumes(burning
off oil, etc.). Be prepared for any
smoke and fumes by raising
windows or opening doors to
provide additional ventilation
during this initial operating
period.
HOW THIS APPLIANCE OPERATES
4
This heater is to be installed either wall mounted or freestanding
according to these instructions and must not be enclosed within a
confinedspace or within acabinet. Itis intended to provideheat directly
to the space in which it is located. The heater is designed, tested and
built to operate safely, when installed according to these instructions, in
areasbuiltof material common to residential construction. Any alteration
of the heater or any installation and use not in accordance with these
instructions may be hazardous. Refer to "SELECTING ALOCATION" and
"COMBUSTION AND VENTILATIONAIR REQUIREMENTS"sectionsof this manual
fordetails.
Theheater’sburner plaques produce heat as soon as they are lit. During
operation,theheatergivesoff infrared radiant heat which travels through
the air and heats nearby objects first, then heats the room air.
The control system on this heater is a safety system that must not be
tampered with. Do not attempt to make any adjustments to the control
orpilot other than those describedinthe "INSTALLATION AND ADJUSTMENT"
or "TROUBLESHOOTING"sections of this manual.
The control system on this heater serves several functions. It regulates
theincoming gastothecorrectpressure forthecombustionraterequired.
Itwill not regulate LP gas directly fromthecontainer;aseparateregulator
mustbe installedonthetank orbottletoreduce thegaspressuresupplied
to the heater to between 11 and 13 inches water column. The control
system also provides a safety shutoff to allow gas to flow to the burner
assembly only when the pilot is burning and to shut off gas to both the
pilot and burner assembly should the pilot flame not be burning. The
control system provides a manual valve to turn gas on and off to the
burnerassembly. Thecontrolhasa thermostatwhichautomaticallyshuts
offtheburnerassemblywhen the room reaches a selected temperature.
There is a safety feature in the control valve which will lock the control
knob in the ‘Off’ position until the pilot valve closes, should the control
knobbe accidentally turned to ‘Off’whilethe pilot is burning; this prevents
escape of unburned gases. The control system also regulates the pilot
gas flow as required for proper operation and provides for shutoff of the
gastothe pilot and burner assembly beforethe oxygeninthearea of the
heater is depleted to dangerous levels.
Air is pulled into the burner assembly by the gas stream and mixed with
thegasinsidetheburnerassemblybeforeburning. Additional airrequired
to complete the burning of the gas enters the heater through its front.
See the “COMBUSTION AND VENTILATION AIR REQUIREMENTS” section of
this manual. Blocking or altering air flow into and away from the heater
couldcauseimpropercombustionandtheproductionof carbonmonoxide
gas that could accumulate to hazardous concentrations. To prevent a
disruption of the air flow through the heater, keep the heater clean as
described by the “MAINTENANCE” section of this manual.
53D9012. Rev 1 03/03

Danger: Do not install this
heater in any area where
gasoline or any combustible or
explosive material will be used
or stored. The flame from this
heater is exposed to the area
around the heater. Contact with
explosive or flammable
materials will lead to explosion
orfire.

These heaters are shipped from the factory equipped for mounting on a
flat wall. A wall-mount template is provided with each heater to aid in
locating the heater on a wall. Maintaining at least the minimum spacing
to combustibles as illustrated by Figure 1 is required for safety. Using
the wall-mount template will help ensure that the required minimum
clearancesbetween the heater andadjacent walls, floor, andceiling are
maintained when mounting the heater on a wall.
The wall-mount anchors provided with each heater are for mounting the
heater to a hollow wall (wall area between studs.) If the heater is to be
mounted to a solid wall such as concrete or masonry, these wall-mount
anchorsshouldnotbeused. Obtainappropriatesolidwall-mount anchors
with number 10 mounting screws from your local hardware store.

A floor stand model XFS is available from your dealer. The floor stand
enables these heaters to be installed freestanding as shown by Figure
2.
Theminimum clearances (see Figure1)between combustible material
and a freestanding heater installed on a floor stand are:
Back - 0 inches (floor stand may touch rear wall)
Floor - 0inches (floor stand may rest directly on floor- See "FLOOR
PROTECTION"information below.)
Sides - 12 inches on one side of the heater;
18 inches on the opposite side of the heater.
Top - 36 inches
Front- 48 inches
When selecting a location for the heater, be sure attention is given to
the following considerations.
1. Some materials such as vinyls and plastics will deform at relatively
low temperatures and must be kept at greater clearance distances
than the minimum clearances specified above.
2. The heater should be located centrally within the area where heat
is desired, but out of traffic areas, or areas where children play, to
minimize the chance of persons accidentally contacting the hot
surface of the heater.
3. The heater must not be located near doorways or in other areas
wheredrafts may affectthe operation ofthepilotor burner assembly.
4. DONOT INSTALL THE HEATER BENEATH CURTAINS OR DRAPES.
To comply with the Z21.11.2 standard of the American National
Standards Institute, none of the heaters described by this manual
may be installed in a bathroom and the IRVF2T is the only model
that may be installed in a bedroom. If an infrared heater is installed
ina bedroom,itmustbewall mounted. Floorstandmountedheaters
are prohibited in bedrooms.
FLOOR PROTECTION
Some Flooring materials will discolor or otherwise deteriorate due to
the temperature underneath the heater. Therefore, when the heater is
installedfreestandingwith a floor stand in placeoncarpet,tile,linoleum
or any combustible material other than wood flooring, the heater must
be installed with a wood panel, metal panel or stoveboard extending at
least the full width and depth of the floor stand. See Figure 2.
Danger: Operationofthe heater
as a freestanding heater without
the proper floor stand correctly
installed may lead to fire or the
production of carbon monoxide
gas.
Warning:Ifheaterisinstalledand
operated at clearances less than
those specified as minimum in
these instructions, a fire hazard
may exist with possible fire
causing property damage or
personal injury. If the heater is
operated at clearances less than
those specified in these
instructions, insufficient air may
besupplied to theheatercausing
poisonous carbon monoxide to
be produced.
Notice:TheZ21.11.2standard of
theAmerican NationalStandards
Institute prohibits the installation
of a heater with a rating greater
than 6,000 Btu’s per hour in a
bathroom. The standard also
prohibits the installation of a
heater with a rating greater that
10,000 Btu’s per hour in a
bedroom.
Warning: Failure to adequately
protect the flooring materials
undera floormountedheater can
leadto damagedflooring material
orfire.

GAS PIPING AND GAS PRESSURE REQUIREMENTS
7
All gas piping must be installed
to comply with local codes or, in
the absence of local codes, with
the latest edition of the National
Fuel Gas Code ANSI Z223.1/
NFPA54. Ifflexible hoseis used,
it must be listed by a recognized
testing agency.
Danger: Operationof thisheater
on LP gas without an approved
regulator at the supply container
will lead to gas leaks at the
control with possible fire or
explosion.
Caution: The heater and its
individual shutoff valve must be
disconnected from the gas
supply piping system during any
pressuretesting of thatsystemat
test pressures in excess of ˚
PSIG. The heater must be
isolated from the gas supply
piping system by closing its
individual manual shutoff valve
duringany pressuretestingof the
gas supply piping system at test
pressures equal to or less than ˚
PSIG. Pressures in excess of ˚
PSIG will cause damage to the
control valve and may cause
damage to the shutoff valve.
Danger: Do not use candles,
matchesor otherignitionsources
when checking for leaks. Fuel
gasesare very flammableand,in
certainconcentrations,explosive.
Checking for leaks with an open
flame may lead to fire or
explosion.
All gas piping must be installed to comply with local codes or, in the
absence of local codes, with the latest edition of the National Fuel Gas
CodeANSI Z223.1/NFPA54. Do not use flexible hose unless the hose
islistedbyarecognized testing agency for use with gasand isapproved
by the local code authority. Unions in gas lines shall be of the ground
joint type. Compounds used on threaded joints of gas piping must be
resistant to the action of liquefied petroleum gas.
Gas piping must be of sufficient size to provide a minimum natural gas
pressure at the appliance of 7 inches water column or 11 inches for LP
gases. The maximum inlet gas pressure to the heater must not exceed
10.5 inches for natural gas and 13 inches for LP gases. If this heater is
tobe supplied with LPgas(bottled propane or butane)the tank or bottle
supplying the gas must have a regulator that reduces the gas pressure
tobetween 11 and 13 incheswater column. The controlwill not operate
with gas line pressure directly from the tank and may leak gas due to
this excessive pressure.
Include a manual shutoff valve and union in the gas line so the heater
maybedisconnectedforservicing. Includeasedimenttrapanda plugged
1/8-inchN.P.T.tap inthegas line also. The tapmust be accessible fora
test gauge connection and should be located somewhere between the
manual shutoff valve and the heater’s 3/8-inch N.P.T. inlet fitting. See
Figures 2 and 3.
The heater may be mounted on a wall or installed freestanding on an
optionalfloorstand.
A typical gas piping diagram for a freestanding heater installed on a
floor stand is shown by Figure 2.
A typical gas piping diagram for a wall mounted heater is shown by
Figure3.
Use a soap-water solution or a liquid gas leak detector to coat each
jointinthegas line and look for bubbles whichindicate gasleaks. Never
use an open flame when checking for leaks.
Gaseous fuels are highly explosive in certain concentrations and are
very flammable. Any gas leaks in the plumbing supplying gas to this
heater can lead to fire or explosion. REPAIR ALL GAS LEAKS. ALL GAS
LEAKS SHOULD BE REPAIRED BY ACERTIFIED INSTALLER.

COMBUSTION AND VENTILATION AIR REQUIREMENTS
Warning: If the area in which
this appliance 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
byoneofthemethods described
in the National Fuel Gas Code,
ANSI Z223.1/NFPA 54, Latest
Edition, Section 5.3 or
applicable local codes. This
appliance shall not be installed
ina confined spaceor unusually
tight construction unless
provisions are provided for
adequate combustion and
ventilation air.
Caution: Because water is a
product of fuel gas combustion,
all gas-fired appliances will
produce some water vapor
(humidity)whenfired. Thewater
vapor may collect on windows
and walls, especially in
buildings constructed unusually
tight. Providing additional fresh
air will reduce the amount of
water vapor which collects on
the windows and walls.

This heater requires fresh air (oxygen) for proper combustion and
ventilation. Insome cases, butnotall,normalairinfiltration into abuilding
will supply a sufficient amount of fresh air for proper combustion and
ventilation. The number of gas-fired appliances involved, the type of
space being utilized, and the construction tightness of the building
involved must all be considered when determining whether normal air
infiltration is sufficient or if additional fresh air will be needed for proper
combustion and ventilation of the gas-fired appliances installed in a
particular space.
Unconfined space and confined space are the terms used to describe
the space in which gas-fired appliances may be installed. The National
Fuel Gas Code , ANSI Z223.1/NFPA 54 defines a
confined space as a
space whose volume is less than 50 cubic feet per 1,000 Btu per hour
(4.8m≈per kW) of the aggregate input rating of all gas-fired 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 (4.8m≈per
kW) of the aggregate input rating of all gas-fired 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 to-be-defined space. For example, three
rooms in a house are adjoining with interconnecting passageways but
no doors; each room has an 8 foot ceiling. One room is 16 x 12 feet,
one is 12 x 12 feet, and one is 10 x 14 feet. The total volume of the
three rooms is 3,808 cubic feet; (8 x 16 x 12) plus (8 x 12 x 12) plus (8
x 10 x 14) equals 3,808 cubic feet. To be considered an unconfined
space in this example, the total maximum aggregate input rating of all
gas-fired appliances installed in the 3,808 cubic feet space must not
exceed76,160 Btu per hour; (3,808 divided by 50) x 1,000 equals76,160
Btu per hour.
Normalair infiltration into an unconfined space willbeadequatetosupply
thenecessaryfreshairforproper combustionandventilationifthebuilding
isnotconstructedunusuallytight. However,ifthebuildingisofunusually
tight construction, additional fresh air from outside will be required for
proper combustion and ventilation of the gas-fired appliances installed
in the unconfined space. Unusually tight construction is defined as
construction where:
a.) Walls and ceiling exposed to the outside atmosphere have a
continuous water vapor retarder with a rating of 1 perm (6x10-11
kg per pa-sec-m˝) 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
windowanddoorframes, betweensoleplatesandfloors,between
wall-ceiling joints, between wall panels, at penetrations for
plumbing, electrical, and gas lines, and at other openings.
