SAFETY IMPORTANT: Read this owner’s manual carefully and completely before trying to assemble, operate, or service this heater. Improper use of this heater can cause serious injury or death from burns, fire, explosion, electrical shock and carbon monoxide poisoning. NATURAL AND PROPANE/LP GAS: Natural and Propane/LP gas are odorless. An odormaking agent is added to the gas. The odor helps you detect a gas leak. However, the odor added to the gas can fade. Gas may be present even though no odor exists.
SAFETY 1. Do not place Propane/LP supply tank(s) inside any structure. Propane/LP supply tank(s) must be placed outdoors. 2. This heater shall not be installed in a bedroom or bathroom. 3. This heater needs fresh air ventilation to run properly. This heater has an Oxygen Depletion Sensing (ODS) safety shutoff system. The ODS shuts down the heater if not enough fresh air is available. See Air for Combustion and Ventilation, pages 7 through 9. If heater keeps shutting off, see Troubleshooting, page 24. 4.
QUALIFIED INSTALLING AGENCY Only a qualified agency should install and replace gas piping, gas utilization equipment or accessories, and repair and equipment servicing.

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. Today’s homes are built more energy efficient than ever. New materials, increased insulation and new construction methods help reduce heat loss in homes.
AIR FOR COMBUSTION AND VENTILATION VENTILATION AIR Ventilation Air From Inside Building This fresh air would come from an adjoining unconfined space. When ventilating 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 and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas Code, ANSI Z223.
INSTALLATION NOTICE: This heater is intended for use as supplemental heat. 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. WARNING: A qualified service person must install heater. Follow all local codes.

INSTALLATION GAS SELECTION CAUTION: To avoid gas leakage for the gas not being used at the inlet of regulator, a qualified installer or service technician must use supplied cap. You will notice a color coded plunger on the inside of the regulator. This is normal. When the inlet connection fitting is inserted and tightened, this plunger will be pushed back by the fitting making all of the adjustments for the gas being supplied. DO NOT REMOVE THE PLUNGER. The regulator will not work.
INSTALLATION 2. Apply thread sealant to the threads on the connection fitting. While pushing in, rotate the fitting clockwise until the threads engage the regulator. After the fitting has been hand tightened into the regulator use a wrench to complete tightening of the fitting. Install additional fitting to connect to the house supply. FOR NATURAL GAS (NG) INSTALLATION: YELLOW 1. Remove the blue dust cover from the regulator. Blue Dust Cover 2. Remove the metal cap installed over the NG regulator inlet.
INSTALLATION CONNECTING TO GAS SUPPLY WARNING: A qualified service technician must connect heater to gas supply. Follow all local codes. WARNING: This appliance requires a 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator. WARNING: For natural gas, Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas. WARNING: Do not overtighten gas connections. CAUTION: Use only new, black iron or steel pipe.
INSTALLATION Typical Inlet Pipe Diameters Use 3/8" black iron pipe or greater. Installation must include an equipment shutoff valve, union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 16). 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.
INSTALLATION CHECKING GAS CONNECTIONS WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all leaks at once. WARNING: Never use an open flame to check for a leak. Apply a noncorrosive leak detection fluid to all joints. If bubbles form, there is a leak. Correct all leaks at once.
