CAUTION: Never connect heater directly to the Propane supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and Propane/LP supply.
The installer must supply an external regulator. The external regulator will reduce the 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. Pointing the vent down protects it from freezing rain or sleet.

**Operating heater above elevations of 4,500 feet could cause the pilot/ODS to shutdown heater.**
PRECAUTIONS:
1.10,000 BTU units may be installed in a bedroom, but not a bathroom, or any place where a strong wind would shut down the appliance.
WARNING: An unvented heater having an input of more than 10,000 Btu/hr (2 931W) shall not be installed in a bedroom or bathroom.
2.This heater needs outside ventilation air to run properly. The Oxygen Depletion Sensor (ODS) safety shutoff system shuts down the heater if not enough fresh air is available. See Fresh Air for Combustion and Ventilation, page 4.
3.Keep all air openings in heater clear, free of debris or any blockage. This will insure that enough air for proper combustion enters the heater.
4.If heater shuts off, do not relight until you provide fresh, outside air. If heater keeps shutting off, it requires servicing.
5.Turn off and let cool before servicing. Only a qualified service person should service and repair heater.
6.Do not run heater:
DANGER: Carbon monoxide poisoning may lead to death.
Carbon Monoxide Poisoning:
Early signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness, or nausea. If you have these signs, the heater may not be working properly. Get fresh air at once! Have heater serviced. Some people are more affected by carbon monoxide than others. These include pregnant women, persons with heart or lung disease or anemia, those under the influence of alcohol, and those at high altitudes.
Propane/LP Gas:
Propoane/LP gas is odorless. An odor making agent is added to propane/LP gas. The odor helps you detect a Propane/LP gas leak. However the odor added to propane/LP gas may be present even though no odor exists. Make certain you read and understand all warnings. Keep this manual for reference. It is your guide to safe and proper operation of this heater.

FRESH AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate
combustion and ventilation air. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home.
ESTABLISHING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code, NFPA 54/ ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation. All spaces in homes fall into one of the three following ventilation classifications:
1.Unusually Tight Construction
2.Unconfined Space
3.Confined Space
This heater must not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air. The information on pages 4 through 5 will help you classify your space and provide adequate ventilation.
Unusually Tight Construction
If your home meets all of the three following criteria you must provide additional fresh air. See Ventilation Air from Outdoors, page 5.
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 (6 x 10-11 kg per pa-sec-m2) or less with openings gasketed or sealed and
b.Whether stripping has been added on operable windows and doors, and
c.Caulking or sealants are applied to areas such as joints around windows and door frames,
between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.
If you home does not meet all of the three criteria above, see Determine the Type of Heater Location Space, below.
Confined Space and Unconfined Space
The National Fuel Gas Code, NFPA 54/ ANSI Z223.1 defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kW) of the aggregate input rating of all 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 (4.8 m3 per kW) of the aggregate input rating of all 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 unconfined space.
*Adjoining rooms are communication only if there are doorless passageways or ventilation grills between them.
DETERMINING THE TYPE OF HEATER LOCATION SPACE:
Use this method to determine if you have a confined or unconfined space.
Note: the space includes the room in which you install heater plus any adjoining rooms with
doorless passageways or ventilation grills between the rooms.
1.Find the volume of the space by multiplying room length x width x height.
Example: Space size 18ft (length) x 18ft. (width) x 8ft. (height) = 2592
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.
Example: 2592 cu.ft. (volume of space) / 50 cu.ft. = 51.8 or 51,800 (maximum Btu/hr the space can support)
WARNING: 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.
3.Add the Btu/hr of all the fuel-burning appliances in the space such as, Vent–free heater, Gas water
Unvented Liquid Propane Fired Room Heater |

Installation Instructions and Owner’s Manual |
heater, Gas furnace, Vented gas heater, Gas fireplace logs, and Other gas appliances*
*Do not include direct-vent gas appliances. Directvent draws combustion air from the outdoors and vents to the outdoors.
Example: |
|
Gas water heater |
40,000 Btu/hr |
Vent Free Heater + 20,000 Btu/hr |
|
Total |
=60,000 Btu/hr |
4.Compare the maximum Btu/hr the space can support with the actual amount of Btu/hr used.
Example: 51,800 Btu/hr (maximum Btu/hr the space can support)
60,000 Btu/hr (Actual amount of Btu/hr used)
The space in the above example is a confined 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, and the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grills between the rooms. See Ventilation Air From Inside Building (Fig. 2)
B.Vent room directly to the outdoors. See Ventilation Air From Outdoors (Fig. 3).
C.Install a lower Btu/hr heater if lower Btu/hr size makes room unconfined.
If actual Btu/hr used is less than the maximum Btu/hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation.
VENTILATION AIR
Ventilation from Inside Building
This fresh air would come from an adjoining unconfined space. When ventilation to an adjoining unconfined space, you must provide two permanent openings: one within 12” of the ceiling and one within 12” of the floor on the wall connecting the two spaces (see options
1 & 2 of figure 2). You can also remove door into adjoining room (see option3, fig 2). Follow the National Fuel Gas Code NFPA 54/ ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts.
WARNING: Rework worksheet, adding the space of the adjoining unconfined space. The combined space must have enough fresh air to supply all appliance in both spaces.
Ventilation from Outdoors
If necessary provide extra fresh air by using ventilation grills or ducts. Connect these items directly to the outdoors or spaces open to the outdoors. These

*IMPORTANT: Do not provide openings for inlet or outlet into attic. If attic has a thermostat-controlled power vent, heated air entering the attic will activate the power vent.
IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms without enough ventilation air may cause mildew to form from too much moisture. See Fresh Air for Combustion and Ventilation, pages 4 and 5.
INSTALLATION
WARNING: Any change to this heater or its controls can be dangerous.
NOTICE: This appliance is intended for supplemental heating. Use this heater along with your primary heating system. Do not install this heater as your primary heat source. If you have a central heating system, you may run system’s circulating blower while using heater. This will help circulate the heat throughout the house. In the event of a power outage, you can use this heater as your primary heat source for the duration of the outage.
