3 and masonry acid washing materials. If the furnace is installed near an area which will be frequently con- taminated by these substances, the furnace should be sealed from this area so that little contaminated air can reach the furnace.
4 • When installed in a residential garage, the furnace must be positioned so the burners and ignition source are located not less than 18 inches (457 mm) above the floor and protected from physical damage by vehicles.
5 (c) In addition to air needed for combustion, process air shall be provided as required for: cooling of equipment or material, controlling dew point, heating, drying, oxidation or dilution, safety exhaust, odor control, and air for compres- sors.
6 Figure 3 Equipment Located in Confined Spaces; All Air from Outdoors Through Ventilated Attic. See 5.3.3-b. 3. When communicating with the outdoors through hori- zontal ducts, each opening shall have a minimum free area of 1 square inch per 2,000 BTU per hour of total input rating of all equipment in the enclosure.

11 Use a flashlight and small mirror at the cleanout or vent connector to inspect the clay tile liner. If any of the following problems are present: • Tile sections misaligned • Tile sections miss.
12 A B-vent installed as described in this section is considered to be an enclosed vent system, and the sizing tables in National Fuel Gas Code, NFPA 54/ANSI Z223.1 - latest edition and in the National Standard of Canada, CAN/CGA B149.1 and CAN/CGA B149.
13 NATURAL GAS CONNECTION Refer to Figure 11 for the general layout at the furnace. The following rules apply: 1. Use black iron or steel pipe and fittings for the building piping. 2. Use pipe joint compound on male threads only. Pipe joint compound must be resistant to the action of the fuel used.
14 When the gas piping enters through the left side of the furnace, the installer must supply the following fittings (starting from the gas valve): • Straight pipe to reach the exterior of the furnace (Fig- ures 14 & 15). • A ground joint union, drip leg, and manual shutoff valve must also be supplied by the installer.
15 CHECKING GAS PIPING CAUTION To prevent personal injury or property damage due to fire, the following instructions must be performed regarding gas connections, pressure testing, location of shutoff valve and installation of gas piping. Before placing in operation, leak test the unit and gas connections.

21 9. After a 15 second delay while flue products are purged from the furnace heat exchanger, the induced draft blower motor is de-energized. 10. The air circulation blower has an adjustable delay-off timing of 60, 90, 120 or 180 seconds (starting from the time the gas valve closes).
22 Figure 33 Rollout Switch Relocation (Upflow) Figure 34 Rollout Switch Relocation (Counterflow) ROLLOUT PROTECTION DEVICE If the flames from the burners are not properly drawn into the heat exchanger, a protection device will open causing the gas valve to close.
23 BURNER BOX This furnace must use indoor air for combustion. It is not a direct vent furnace, and it cannot be installed as a direct vent furnace. The burner box (on some models) is present only to reduce the burner sound transmission.
24 5. Open Limit Control (Primary or Auxiliary) An open limit control can be caused by a low condi- tioned air flow due to dirty filter or resistance in duct work, a faulty blower, a blower speed set too low, or a faulty limit. When the limit control opens, the induced draft and air circulation blowers are turned on.

27 XI. Maintenance WARNING To prevent death or personal injury due to electric shock, disconnect electrical power before performing any maintenance. IMPORTANT NOTE: Handle the ignitor with care. Touch- ing the ignitor body with bare fingers, rough handling, or vibration could result in early ignitor failure.
28 The furnace-mounted filter rack includes a rack mounted on the top of the furnace. Two filters fit into the rack and rest against the sides of the return air plenum, forming a “V” above the furnace. The filters should be inspected frequently and cleaned or replaced when necessary.
29 BURNERS WARNING To prevent personal injury or death, do not remove any internal compartment covers or attempt any adjustment. Electrical components are contained in both compartments. Contact a qualified service agent at once if an abnormal flame appearance should develop.
