INTRODUCTION Please read our instructions before you install and use your heater. This will help you obtain the full value from this heater. If the answer to the problem is found within this instruction manual, it could help you avoid needless service costs. BASIC DESCRIPTION Always consult your local heating or plumbing inspector, building department or gas company regarding regulations, codes or ordinances which apply to the installation of a vented room heater.

b. Arrangement of the rooms or area to be heated. c. Probable location of the furniture. d. General appearance. e. Safe clearance from anything that could catch fire. f. Ability to properly vent the heater. 2. Locate the heater centrally in the area which it is to heat. The ideal location is at the source of cold air, which is an outside wall. If the heater is on an outside wall, the cold air will be warmed before it moves through the room. 3.

INSTALLING YOUR FURNACE NOTE: Minimum fresh air opening is 1 square inch per 1,000 BTU/hr. FIGURE 2 - LEFT SIDE GAS INLET GAS PIPING State and local authorities have established codes regulating the installation of gas burning equipment. Consult your gas supplier or gas company for complete information. In the absence of local codes, all aspects of the installation must comply with the National Fuel Gas Code ANSI Z223.1. In Canada: Follow the CAN/CGA-B149.1(2) Canadian Standard. 1.

FIGURE 4 - ENCLOSED MODEL fuel burning appliances. Any use of appliances that pull air out of the house (clothes dryers, exhaust fans, fireplaces, etc.) increases this problem and appliances could be starving for air. In addition, these energy measures mean that your home will retain more water vapor or a higher relative humidity. High humidity, especially during cold weather, may be damaging to buildings because condensation forms on windows and inside walls.
PAGE 10
INSTALLING YOUR FURNACE LOUVERS / GRILLES AND SCREENS COVERING 3. FREE AREA OPENINGS a) If spillage stops, do not use exhaust fans until you can supply fresh air by a permanent duct. If a screen is used to cover the opening(s), it must not be smaller than 1/4-inch mesh. Use the free area of a louver or grille to determine the size opening required to provide the free area specified. If the free area is not known, assume a 20% free area for wood and a 60% free area for metal louvers or grilles.
PAGE 11
WARNING: Danger of property damage, bodily injury or loss of life. The adjoining unconfined space must have adequate air infiltration as defined in example 1. FOR EXAMPLE: Your furnace is rated at 50,000 BTU/hr. The water heater is rated at 30,000 Btu/hr. The total is 80,000 BTU/hr. You need two grilles, each with 100 square inches of free opening. Metal grilles have about 60% free area, so you need two metal grilles each with 160 square inches of louvered area.
PAGE 12
INSTALLING YOUR FURNACE FIGURE 10 – AIR FROM OUTDOORS OR CRAWL SPACE 3. Before drilling a hole in the wall at the selected location, drive a small finishing nail through the ceiling in the corner of the wall and ceiling above the thermostat location. Pull the nail out and push a small stiff wire through the hole so it can be found in the attic. Drill a ½-inch hole through the ceiling wall plate. 4. Probe for obstructions in the partition.

taping lightly with a screwdriver. It will also be necessary to cut the inside panel insulation about a ½-inch in diameter for clearance to the knockout. Vent Installation 2. Cut the thermostat wire to the desired length. 3. Connect the thermostat wires to the terminal screws on the back of the thermostat base. 4. Feed the thermostat wires through the knockout and route through the metal clip to the gas valve. Models, 2001621A and 2001622A do not have a metal clip.
PAGE 14
INSTALLING YOUR HEATER 3. Use vent pipe of the same size as the outlet on back of heater. In no case should a different size vent be used. Single wall vent pipe may be attached directly to the draft hood of the room heater when a clearance of 3 inches (76.2 mm) is maintained between the single wall vent pipe and the combustible wall of the room in which the room heater is located. Use double wall vent pipe for clearances less than 3 inches (76.2 mm) to combustibles. 4.

OPERATING YOUR HEATER Start-Up Procedure Start the heater using the procedures in the section “Operating Your Heater”. CHECK THE GAS INPUT (NATURAL GAS ONLY) WARNING: Natural gas heating value (BTU per cubic foot) can vary significantly. Therefore, it is the installer’s responsibility to see that BTU/hr. input to the heater is adjusted properly. Failure to do so could cause combustion chamber failure, asphyxiation, fire or explosion resulting in damage, bodily injury or death.
PAGE 17
FIGURE 18 - BURNER FLAME CHARACTERISTICS WARNING: Natural gas heating value (BTU per cubic foot) can vary significantly; therefore, it is the installer’s responsibility to see that the BTU input to the heater is adjusted properly. Failure to do so could cause combustion chamber failure, asphyxiation, fire or explosion, resulting in property damage, bodily injury or death. Refer to the National Fuel Code (NFPA-54) to be sure the heater is burning fuel at the proper rate.
PAGE 18
OPERATING YOUR HEATER C. Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, don’t try to repair it, call a qualified service technician. Force or attempted repair may result in a fire or explosion. D. Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.
PAGE 19
CARING FOR YOUR HEATER WARNING: DUE TO HIGH SURFACE TEMPERATURES - KEEP CHILDREN, CLOTHING, FURNITURE OR ANY COMBUSTIBLE MATERIAL AWAY FROM THE HEATER. Make sure the “FOR YOUR SAFETY” hang tag (see below) hangs below the heat shield. How To Care For Your Heater WARNING: Danger of bodily injury or death. Turn off electric power supply at the disconnect switch, fuse box or service panel before removing any doors or access or service panels from the unit.
PAGE 20
CARING FOR YOUR HEATER Cleaning burner compartment Because cold air is attracted to the flame during heater operation, a build up of lint from carpeting, bedding, dust, etc. in the burner area will occur. It is necessary to clean this area regularly. Use a vacuum cleaner with a narrow attachment to reach small areas. Be careful in and around the pilot. A change in its adjustment could be made if moved during cleaning.

TROUBLESHOOTING YOUR FURNACE For qualified service technicians. ISSUE POSSIBLE CAUSE(S) CORRECTIVE ACTION 1. Pilot will not stay lit after following lighting instructions. A. Generator producing insufficient millivolts. Check pilot flame – it must impinge on the generator from 1/4 to 3/8-inches . Be sure the thermocouple is fully inserted in its bracket. B. Loose or dirty generator connections at gas valve. Clean and/or tighten the connections at the valve. C. Generator defective.
PAGE 31
ISSUE POSSIBLE CAUSE(S) CORRECTIVE ACTION draft hood as possible to allow venting to begin before any restriction is encountered. The use of too many offsets may also prevent proper venting. 8. Abnormal operation. 9. Noisy blower. 10. Blower does not run. D. Incorrect vent pipe. Use listed B/W type vent pipe. DO NOT use transite or any other type of ceramic pipe for venting. DO NOT use single wall pipe.
