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 (30 mL) of water for every 1,000 BTUs (.3 Kw) of gas input
per hour. An unvented room heater is intended as a supplemental heater rather than a primary heat
source. 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.
The following steps will help ensure that water vapor does not become a problem:
1. Be sure the heater is the proper size for the application, including adequate combustion air and
circulation air.
2. If there is high humidity, a dehumidier 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.

PREPARING FOR INSTALLATION
AIR FOR COMBUSTION AND VENTILATION
CAUTION: This heater shall not be installed in a room or space unless the required volume of
indoor combustion air is provided by the method described in the National Fuel Gas Code, ANSI
Z223.1/NFPA54, the International Fuel Gas Code, or applicable local codes.
PRODUCING ADEQUATE VENTILATION
All spaces in homes fall into one of the three following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 7 through 9 will help you classify your space and provide adequate ventilation.
Conned and Unconned Space
A conned space as a space whose volume is less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw)
of the aggregate input rating of all appliances installed in that space and an unconning space as a
space whose volume is not less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate
input rating of all appliances installed in that space. Rooms connecting directly with the space in
which the appliances are installed*, through openings not furnished with doors, are considered a
part of the unconned space.
This heater shall not be installed in a conned space or unusually tight construction unless provisions
are provided for adequate combustion and ventilation air.
* Adjoining rooms are connecting only if there are doorless passageways or ventilation
grills between them.
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 dened as construction where:
a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder
with a rating of one perm (6x10-11kg per pa-sec-m2) or less with openings gasketed or sealed
and
b) weather stripping has been added on windows that can be opened and on doors and
c) caulking or sealants are applied to areas such as joints around window and door frames,
between sole plates and oors, 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.
See “Ventilation Air From Outdoors” (page 9). If your home does not meet all of the
three criteria above, proceed to “Determining Fresh-Air Flow For Heater Location”.

PREPARING FOR INSTALLATION
DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Conned or Unconned Space
Use this worksheet to determine if you have a conned or unconned space.
Space: Includes the room in which you will install heater plus any adjoining rooms with
doorless passageways or ventilation grills between the rooms.
1. Determine the volume of the space Length × Width × Height = cu. ft. (volume of space)
Example: Space size 20 ft. (length) × 16 ft.(width) × 8 ft. (ceiling height) = 2560 cu. ft. (volume
of space)
If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these
rooms to the total volume of the space.
2. Divide the space volume by 50 cu. ft. to determine the maximum BTU/hr the space can support.
_______ (volume of space) ÷ 50 cu. ft.= (Maximum BTU/hr the space can support)
Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum BTU/hr the space
can support)
3. Add the BTU/hr of all fuel burning appliances in the space.
Vent-free heater _________ BTU/hr
Gas water heater* ________BTU/hr
Gas furnace _____________BTU/hr
Vented gas heater ________BTU/hr Example:
Gas heater logs __________BTU/hr Gas water heater 30,000 BTU/hr
Other gas appliances*+ ____BTU/hr Vent-free heater + 26,000 BTU/hr
Total = ____BTU/hr Total = 56,000 BTU/hr
*Do not include direct-vent gas appliances. Direct-vent draws combustion air from the
outdoors and vents to the outdoors.
4. Compare the maximum BTU/hr the space can support with the actual amount of BTU/hr used.
_______ BTU/hr (maximum the space can support)
_______ BTU/hr (actual amount of BTU/hr used).
Example : 51,200 BTU/hr (maximum the space can support) 56,000 BTU/hr (actual amount of
BTU/hr used)
The space in the above example is a conned space because the actual BTU/hr used is more than
the maximum BTU/hr the space can support.
You must provide additional fresh air. Your options are as follows:
a) Rework worksheet, adding the space of an adjoining room. If the extra space provides an
unconned space, remove door to adjoining room or add ventilation grills between rooms. See
“Ventilation Air From Inside Building,” page 9.
b) Vent room directly to the outdoors. See “Ventilation Air From Outdoors”, page 9.
c) Install a lower BTU/hr heater if lower BTU/hr size makes room unconned. If the actual BTU/hr
used is less than the maximum BTU/hr the space can support, the space is an unconned space.
You will need no additional fresh air ventilation.
9
PREPARING FOR INSTALLATION
Ventilation Air From Inside Building
This fresh air would come from adjoining
unconned space. When ventilating to an
adjoining unconned space, you must
provide two permanent openings: one
within 12 in. of the wall connecting
the two spaces (see options 1 and 2,
Fig. 1). You can also remove door into
adjoining room (see option 3, Fig. 1).
Follow the National Fuel Gas Code
NFPA 54/ANS Z223.1. Air for Combustion
and Ventilation for required size of
ventilation grills or ducts.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or duct. You must provide two
permanent openings: one within 12 in. of
the ceiling and one within 12 in. of the oor.
Connect these items directly to the outdoors
or spaces open to the outdoors. These
spaces include attics and crawl spaces.
Follow the National Fuel Gas Code NFPA
54/ANS Z223.1. Air for Combustion and
Ventilation for required size of ventilation
grills or ducts.
IMPORTANT: Do not provide openings for
inlet or outlet air into attic if attic has a
thermostat-controlled power vent. Heated
air entering the attic will activate the power
vent. Rework worksheet, adding the space
of the adjoining unconned space. The
combined spaces must have enough fresh
air to supply all appliances in both spaces.

INSTALLATION
Attaching to Expansion Bracket Method
For attaching mounting bracket to hollow walls (wall areas
between studs) or solid walls (concrete or masonry):
1. Drill holes at marked locations using 5/16-inch drill bit.
For solid walls (concrete or masonry), drill at least
1 inch deep.
2. Fold wall expansion bracket as shown in (See Fig. 17).
3. Insert wall expansion bracket (wings rst) into hole. Tap
expansion bracket ush to wall.
4. For thin walls (1/2 inch or less), insert expansion
bracket tool into expansion bracket. Push expansion
bracket tool to “pop” open expansion bracket wings
(See Fig. 18).
IMPORTANT: Do not hammer expansion bracket tool!
For thick walls (over 1/2 inch thick) or solid walls, do not
pop open wings.
5. Place mounting bracket onto wall. Line up last hole on
each end of bracket with expansion bracket.

wall mounting bracket and into expansion brackets.
7. Tighten expansion bracket screws (ST4.8*15-16) until
mounting bracket is rmly fastened to wall.
8. Check that the bracket is secure before mounting
heater!
Attaching Wall Hanging Spacers to Heater
WARNING: Failure to properly install the wall hanging
spacers may result in property damage, personal injury
or even death.
1. Locate spacer mounting holes on the lower right/left
sections of the heater back panel.
2. Secure (2) wall hanging spacers to heater back panel
using (2) wall hanging spacer screws (M4*25) (See Fig.
19a).

INSTALLATION
CONNECTING TO GAS SUPPLY
WARNING: A qualied service technician must connect heater to gas supply. Follow all local
codes.
IMPORTANT: This appliance requires a 3/8-inch NPT (National Pipe Thread) inlet connection to
the pressure regulator. Never connect the heater to private (non-utility) gas wells, commonly
known as wellhead gas.
WARNING: Do not overtighten gas connections.
CAUTION: Use only new, black iron or steel pipe. Internally tinned copper tubing may be used
in certain areas. Check your local codes. Use pipe of 1/2-in. diameter or greater to allow proper
gas volume to heater. If pipe is too small, undue loss of pressure will occur.
CAUTION: Check your gas line pressure before connecting heater to gas line. Gas line pressure
must be a minimum 6" WC for NG and 11" WC for LP with a max pressure of 14"WC. If gas line
pressure is higher, heater regulator damage could occur.
CAUTION: Never connect heater directly to an LP supply. This heater requires an external
regulator (not supplied). Install the external regulator between the heater and gas supply.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas
piping and/or ttings.
CAUTION: Use pipe joint sealant that is resistant to gas (Propane or Natural Gas).
Typical Inlet Pipe Diameters
Use 3/8-inch black iron pipe or greater. Installation must include an equipment shutoff valve, union,
and plugged 1/8-inch NPT tap.
Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater
(see Fig. 20).
IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff
valve is for turning on or shutting off the gas to the appliance.
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going
into pipe. Excess sealant in pipe could result in clogged heater valves.

INSTALLATION
Install sediment trap in supply line as shown
(See Fig. 20). Place sediment trap where it is
within reach for cleaning. Place sediment trap
where trapped matter is not likely to freeze. A
sediment trap traps moisture and contaminants.
This keeps them from going into heater controls.
If sediment trap is not installed or is installed
wrong, heater may not run properly.
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all
leaks immediately.
WARNING: Never use an open ame to check for a leak. Apply a 50/50 mixture of liquid soap and
water to all joints. If bubbles form, there may be a leak. Correct all leaks immediately.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG ( 3.5kPa )
Fig. 20 - Gas Connection
The appliance and its appliance main gas valve must be disconnected from the gas supply piping
system during any pressure testing of that system at test pressures in excess of ½ psi (3.5 kPa).
Pressure Testing Gas Supply Equal To or less than
1/2 PSIG ( 3.5kPa )
The appliance must be isolated from the gas supply piping system by closing its equipment shut-off
valve during any pressure testing of the gas supply piping system at test pressures equal to or less
than
½ psi (3.5 kPa).
Leak Testing Heater Gas Internal Connections
1. Open equipment shutoff valve (See Fig. 21).
2. Make sure control knob of heater is in the OFF position.
3. Open gas supply tank valve (LP systems).
4. Check all joints from equipment shutoff valve to control
valve. Apply 50/50 mixture of
liquid soap and water to gas joints. If bubbles form, there
may be a leak.
5. Light heater (see Operation, page 18). Check all other
internal joints for leaks.
6. Turn off heater (see "To Turn Off Gas to Appliance,"
page 19).
