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. The furnace must still have an adequate supply of combustion air, either from a nearby uncontaminated room or f[...]

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.

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 B149.2 - latest editions and amend- ments may be used. If a flexible liner is to be used, it must be [...]

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. 3. Use ground joint unions. 4. Install a drip leg [...]

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. In some cases, the in[...]

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.

18 HEAT ANTICIPATOR SETTING Adjust the heat anticipator in the room to obtain the proper number of heating cycles per hour. The heat anticipator is a wire-wound adjustable heater that prevents the room temperature from “overshooting” the room thermostat set- ting. The heat anticipator must be set at 0.7 amps. The heat anticipator is part of the[...]

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). This allows more heat from the furnace to be transferred to the c[...]

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. The induced draft blower will r[...]
