Figure 1 - Vent-Free Gas Heater
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 KWs) of gas input per hour. Unvented room heaters are recommended 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.
The following steps will help ensure 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 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.

AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall not be installed in a conned space or unusually tight construction unless
provisions are provided for adequate combustion and ventilation air. Read the following instructions to ensure
proper fresh air for this and other fuel-burning appliances in your home.
Providing Adequate Ventilation
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/NFPA 54, the INTERNATIONAL FUEL
GAS CODE, or applicable local codes.
The following are excerpts from National Fuel Gas Code, ANSI Z223.1/ NFPA 54. Air for Combustion and 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 9 through 11 will help you classify your space and provide adequate ventilation.
Conned and Unconned Space
The National Fuel Gas Code, ANSI Z223.1/NFPA 54 denes 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 unconned space as a space whose volume is not less than 50 cubic feet 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:
Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of
a)
one perm (6×10
Weather stripping has been added on openable windows and on doors and
b)
Caulking or sealants are applied to areas such as joints around window and door frames, between sole plates
c)
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”. If your home does not meet all of the three criteria above, proceed to “Determining Fresh-Air Flow For
Heater Location”.

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 =
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 cubic feet to determine the maximum BTU/hr the space can support.
(volume of space) ÷ 50 cu. ft. =(Maximum BTU/hr the space can support)
3. Add the BTU/hr of all fuel burning appliances in the space.
Vent-free heater
Gas water heater*
Gas furnace
Vented gas heater
Gas heater logs
Other gas appliances* +
Total =
*Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the
outdoors.

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:
Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space,
a)
remove door to adjoining room or add ventilation grills between rooms. See “ Ventilation Air From Inside Building ”
on next page.
Vent room directly to the outdoors. See “ Ventilation Air From Outdoors ” on next page.
b)
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.
1010
WARNING: If the area in which the heater
may be operated is smaller than that dened as an
unconned 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.
WARNING: If the area in which the heater may be
operated does not meet the required volume for indoor
combustion air, combustion and ventilation air shall
be provided by one of the methods described in the
NATIONAL FUEL GAS CODE, ANSI Z223.1/
NFPA 54, the INTERNATIONAL FUEL GAS CODE, or
applicable local codes.
Ventilation Air From lnside Building
This fresh air would come from an adjoining unconned
space. When ventilating to an adjoining unconned
space, you must provide two permanent openings: one
within 12 inches of the ceiling and one within 12 inches
of the oor on the wall connecting the two spaces
(see options 1 and 2, Figure 2). You can also remove
the door into adjoining room (see option 3, Figure 2).
Follow the National Fuel Gas Code. ANSI Z223.1/
NFPA 54
, Air for Combustion and Ventilation for
required size of entilation grills or ducts.
Figure 2 - Ventilation Air from Inside Building
NOTE: Base no t i ncluded. Not for use in
bedrooms or bathrooms.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or
ducts. You must provide two permanent openings: one
within 12 inches of the ceiling and one within 12 inches
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, ANSI Z223.1/ NFPA 54, 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.

WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.
WARNING: Do not over-tighten 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.
NATURAL GAS MODELS:
CAUTION: Check your gas line pressure before connecting heater to gas line. Gas line pressure must be no
greater than 10.5 inches of water. If gas line pressure is higher, heater regulator damage could occur.
PROPANE MODELS:
CAUTION: Never connect heater directly to the gas 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 Figure 12).
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.
Figure 12 - Gas Connection (inches)
* Purchase the optional CSA design-certied equipment shutoff valve from your dealer.
1515
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.
The installer must supply an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas pressure to between 11 and
14 inches of water. If you do not reduce incoming gas pressure, heater regulator
damage could occur. Install external regulator with the vent pointing down as shown
in Figure 13. Pointing the vent down protects it from freezing rain or sleet.
Install sediment trap in supply line as shown in Figure 12. 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.

Vent Pointing Down
INSTALLATION
Continued
CAUTION: Two gas line installation at the same time is forbidden. Do not the open cover while the heater is
running.
Heater is pre-set at factory for propane gas; no changes are required for connecting to propane. Only a qualied installer
or service technician can perform gas selection and connecting to gas supply.
CAUTION: To avoid gas leakage at the inlet of regulator, a qualied installer or service technician must use
steel or metal hex plug with sealant.
For changing from propane to natural gas supply:
1. Remove top screw from cover plate, See Figure 14, and rotate to expose gas selection valve.
2.
For NATURAL GAS, press knob using a at screwdriver with a blade with thickness of a quarter and turn knob
counterclockwise until the knob locks into the NG position (see Figure 15). Selection valve must be locked in
the NG position. Do not operate heater between locked positions!
3. Rotate and close cover over gas selection valve and reinstall screw.
4. Remove steel or metal hex plug (with wrench provided) from natural gas inlet of regulator and install into LP inlet of
regulator; use thread sealant to ensure that there are no leaks.
