Installing Your Heater AIR REQUIREMENTS FIGURE 6 The requirements for providing air for combustion and ventilation are listed in the National Fuel Gas Code NFPA 54/ANSI Z223.1 (in Canada: CAN/CGA B149). Most homes will require that outside air be supplied to the heated area by means of ventilation grilles or ducts connecting directly to the outside or spaces open to the outdoors such as attic or crawl space.
PAGE 10
Installing Your Heater 4. Spillage means air starvation and a fresh air duct or air intakes must be installed to provide air directly to the furnace or other gas appliance. D. If spillage exists or when the furnace is in a building of tight construction where the windows and doors are weatherstripped, air for combustion and ventilation must be obtained from outdoors or space open to the outdoors. Provide an opening(s) having a total free area of 1-square inch per 4000 Btu/hr.

Installing Your Heater FIGURE 9 Grilles Connecting Rooms to Make Unconfined space FIGURE 10 Air from Outdoors or Crawl Space Openings for inlet or outlet air should not be made into attic area if attic is equipped with a thermostat controlled power vent. FIGURE 11 Free Area Btu/hr./Input FOR EXAMPLE: Your furnace is rated at 50000 Btu/hr. The water heater is rated at 30,000 Btu/hr. The total is 80,000 Btu/hr.

Installing Your Heater CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing. Refer to installation instructions packed in the thermostat carton if you have any doubt about the above procedures. 7. Connect the thermostat wires to the control valve as shown in Figure 5. IMPORTANT: KEEP THE THERMOSTAT WIRE AWAY FROM THE COMBUSTION CHAMBER. Wall-Mounted Thermostat Installation 1.
PAGE 13
Installing Your Heater Vent Installation This heater must be properly connected to a venting system. This heater is equipped with a vent safety shutoff system to protect against improper venting of combustion products. Tampering with or removal of this control will void the limited warranty and can result in carbon monoxide (CO) poisoning and possible death.
PAGE 14
Installing Your Heater IMPORTANT: Inspect venting system prior to each heating season. Typical Methods of Safely Venting Your Heater 1. Any horizontal run of vent pipe must slope upward a minimum of 1/4” per foot. Secure all joints of the vent with sheet metal screws. 2. Where the vent passes through the ceiling or wall, a thimble is required to keep the ceiling from catching fire. Use only a thimble designed for use with Type “B” gas vent, certified by a nationally recognized testing agency. 3.

Operating Your Heater Start-Up Procedure Start the heater using the procedures in the section “Operating Your Heater”. WARNING: Danger of bodily injury or death. L.P. Gas is heavier than air and it will settle in any low area, including open depressions and it will remain there unless the area is ventilated. Never attempt to start-up the unit before thoroughly ventilating the area. Check the heater operation as outlined in the following instructions.
PAGE 17
Operating Your Heater FIGURE 18 Burner Flame Characteristics Abnormal Appearance Lazy Flame: Long soft yellow cones moving around in the combustion chamber lifting from ports (insufficient air). Extremely Fast Flame: Will not hold to ports - entire cone sections blow off from noisy ports (too much pressure). WARNING: If the flame appears abnormal, contact the gas company or a qualified service technician immediately. Burner Flame Characteristics Start the heater and let it operate for at least 10 minutes.

Care – 19 Caring for Your Heater 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. For better circulation and more effective heating, do not place obstructions, furniture or other items closer than four feet to the front of the cabinet or two feet from each side of the cabinet.
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.

Accessories– 27 Blower Accessory 2102 Mounting the Blower Note: All electrical work must conform to your local codes and ordinances or in their absence, with National Electrical Code, ANSI/NFPA 70. If you are not familiar with wiring codes in general, have a competent electrician do this job. In CANADA: CANADIAN ELECTRICAL CODE C22.1. WARNING: Danger of property damage, bodily injury or death.
PAGE 28
Blower Accessory 2102 Operation This accessory is operated using the factory equipped, three-prong (grounding) plug and cord. When using the plug and cord, for your protection against shock hazard, it must be plugged directly into a properly grounded three-prong receptacle. DO NOT CUT OR REMOVE THE PRONG. You must select “HI” or “LO” on the speed switch (item 8) for automatic blower operation. When the heater heats up, the fan switch is activated and the blower will operate.
PAGE 29
Troubleshooting SYMPTOM 1. Pilot will not stay lit after following lighting instructions. 2. Pilot burning - no gas to the main burner. 3. Burner comes "ON" but goes OFF before blower turns ON. 4. Heater not producing sufficient heat. POSSIBLE CAUSE CORRECTIVE ACTION 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.
PAGE 30
Troubleshooting SYMPTOM 5. Heater operates, but will not shut off after room temperature is attained. 6. Pilot outage. 7. Main burner will not stay on. 30 POSSIBLE CAUSE CORRECTIVE ACTION A. Thermostat wiring defective. Thermostat lead wires may be shorted together, caused by a nail or staple. Check by removing thermostat leads from valve terminals. B. Thermostat location. Check thermostat location.
PAGE 31
Troubleshooting 8. Abnormal operation. 9. Noisy blower. A. Delayed ignition - pilot flame may be too low. Adjust pilot flame. Refer to "How to Care for Your Heater" section in this manual. B. Expansion noise, ticking. Heater may be distorted by being vented through an uneven opening. A restricted vent may create expansion noise. Refer to "Venting" section of this manual. C. Combustible gas spillage.
