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, pages 23 through 25. 4.
PRODUCT FEATURES SAFETY PILOT This heater has a pilot with an Oxygen Depletion Sensing (ODS) safety shutoff system. The ODS/pilot shuts off the heater if there is not enough fresh air. PIEZO IGNITION SYSTEM This heater is equipped with an electronic piezo control system. This system requires AAA batteries (provided). THERMOSTAT HEAT CONTROL The control automatically cycles the burner on and off to maintain a desired room temperature. See page 20.
PREPARING FOR INSTALLATION Before beginning assembly or operation of the product, make sure all parts are present. Compare parts with package contents list. If any part is missing or damaged, do not attempt to assemble, install, or operate the product. Contact customer service for replacement parts.
AIR FOR COMBUSTION AND VENTILATION 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 PRODUCING ADEQUATE VENTILATION All spaces in homes fall into one of the three following ventilation classifications: 1. Unusually Tight Construction 2.
DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION Determining if You Have a Confined or Unconfined Space Use this worksheet to determine if you have a confined or unconfined 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.
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 Inside Building This fresh air would come from adjoining unconfined space.
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. WARNING: A qualified technician must install heater. Follow all local codes.
LOCATING HEATER This heater is designed to be mounted on a wall. For convenience and efficiency, install heater: 1) Where there is easy access for operation, inspection, and service. 2) In the coldest part of room. Fig. 4 - Moving Thermostat Sensing Bulb INSTALLING THERMOSTAT SENSING BULB (OPTIONAL) 1. Pull out the sensing bulb from the two clips located in the shipping position. There is no need to take out the two bulb clips. 2.
Marking Screw Locations 1. Tape mounting bracket to wall where heater will be located. Make sure mounting bracket is level. Fig. 6 - Mounting Bracket Clearances (inches) Item # 0348820 (Model # MD3TPF) WARNING: Maintain minimum clearances shown in Fig. 3. If you can, provide greater clearances from floor and joining wall. 2. Mark screw locations on wall (see Fig. 6). Adjoining AdjoiningWall Wall Note: Mark only last hole on each end of mounting bracket. Insert mounting screws through these holes only. 3.
Attaching to Wall Anchor 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. Fig. 7 - Folding Anchor 2. Fold wall anchor as shown in Fig. 7. 3. Insert wall anchor (wings first) into hole. Tap anchor flush to wall. 4. For thin walls (1/2 inch or less), insert white key into wall anchor.
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-inch NPT (National Pipe Thread) inlet connection to the pressure regulator. WARNING: 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. Internally tinned copper tubing may be used in certain areas.

The external regulator will reduce incoming gas pressure.
CONNECTING TO GAS SUPPLY (CONTINUED) CAUTION: Two gas line installations at the same time are prohibited. The access plate to the simple switching means shall not be opened while the heater is in operation. This appliance can be used with propane or natural gas. It is shipped from the factory adjusted for use with propane. Only a qualified installer or service technician can perform gas selection and connecting to gas supply.
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 flame to check for a leak. Apply a mixture of liquid soap and water to all joints. If bubbles form, there may be a leak. Correct all leaks immediately.

OPERATION FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury, or loss of life. NOTICE: During initial operation of new heater, burning logs will give off a paper burning smell. Orange flame will also be present. Open a window to vent smell. This will last only few hours. CAUTION: Do not try to adjust heating levels by using the equipment shutoff valve. A.
LIGHTING INSTRUCTIONS Unscrew ignitor cap and install a AAA battery with the + pointing out. Replace cap. 1. STOP! Read the safety information on the side of the heater. 2. Make sure equipment shutoff valve is fully open. 3. Turn control knob clockwise to the OFF position. 4. Wait five (5) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Do not try to light any appliance. Do not touch electrical switch or use any phone in the building.
THERMOSTAT CONTROL OPERATION Fig. 17 - Control Knob Position The thermostatic control used on this model differs from standard thermostats. Standard thermostats simply turn the burner on and off. The thermostat used on this heater senses the room temperature. At times the room may exceed the set temperature. If so, the burner will shut off. The burner will cycle back on when room temperature drops below the set temperature. The control knob can be set to any comfort level between HIGH (5) and LOW (1).
INSPECTING BURNERS Check pilot flame pattern and burner flame patterns often. PILOT FLAME PATTERN Figure 19 shows a correct pilot flame pattern. Figure 20 shows a incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool, which shuts the heater off. If pilot flame pattern is incorrect: • turn heater off (see “To Turn Off Gas to Appliance” on page 20) • see Troubleshooting pages 23 through 25. Fig.
CARE AND MAINTENANCE WARNING: Turn off heater and let cool before servicing CAUTION: You must keep control areas, burner, and circulating air passageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service technician. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc. ODS/PILOT AND BURNER Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean.
TROUBLESHOOTING WARNING: If you smell gas: • Shut off gas supply. • Do not try to light any appliance. • Do not touch any electrical switch; do not use any phone in your building. • Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions. • If you cannot reach your gas supplier, call the fire department. IMPORTANT: Operating heater where impurities in air exist may create odors.
