bustion or the furnace can use air from inside the structure for com- bustion. The INLET air pipe isoptional. If combustion air comes from inside the structure, adequate make u p air MUST be provided to compensate for oxygen burned. See Confined Space Installa- tion in the Combustion and Ventilation Air chapter.
3. Insulate combustion air inlet piping when run in warm, hu- mid spaces such as basements. Sizing Combustion Air and Vent Pipe Consult Table 3 or Table 4 to select the proper diameter exhaust and combustion air piping.

The air intake coupling is sized for 2" PVC pipe. Install the combustion air pipe to the air intake coupling using RTV sealant to provide for future serviceability.
1, Install all couplings, nipples and elbows using proper proce- dures for Joining Pipe and Fittings and maintain spacing between vent and combustion air piping as indicated in Figure 20 through Figure 28. MIN. _18" Minimum for cold climates (substained below 0 ° F) MIN.
Multi Vent Termination Clearances When two (2) or more furnaces are vented near each other, each furnace must be individually vented. Two (2) vent terminations may be installed as shown in Figure 23, Figure 24, Figure 25, Figure 26, Figure 27 and Figure 28, but the next vent termination must be at least 36" away from first 2 ter- minations.
5. Gas Supply and Piping CARBON MONOXIDE POISONING, FIRE AND EXPLOSION HAZARD. Failure to follow these instructions could result in death, personal injury and/or property damage. Models designated for Natural Gas are to be used with Natural Gas ONLY, unless properly converted to use with LP gas.

3. Time how many seconds it takes the smallest dial on the gas NOTE: If meter uses a 2 cubic foot dial, divide results (seconds) by meter to make one complete revolution. Refer toExample. two. 4. Relight all appliances and ensure allpilots are operating.
NOTE: Refer toFigure 30 orFigure 31 for the general layout at the furnace. The rules listed apply to natural and LP gas pipe installations. NOTE: On the Dual Certified or Direct Vent models, install the gas pipe grommet tothe furnace side panel with the gas pipe entry.
REDUCED FURNACELIFE HAZARD Failure to follow caution instructions may result in reduced furnace life. Do NOT exceed 115V/0.8 amp. maximum current load for both the EAC terminal and the HUM terminal combined. NOTE: The humidifier will be powered when the furnace is fired and the circulating air blower comes on.
7. Ductwork and Filter CARBON MONOXIDE POISONING HAZARD. Failure to properly seal duct could result in death and/or personal injury. Do NOT draw return air from inside a closet or utility room where furnace is located. Return air duct MUST be sealed to furnace casing.
Mounted Filter Rack 25-20-90 Filter Installation using Optional Filter Rack When installing or removing a bottom mounted filter, slide the two side filter clips to the back of the furnace BEFORE installing or re- moving. This will allow the filter to clear the front raised edge of the furnace.

Main Burner Face 10-10-78 Temperature Rise Check The blower speed MUST be set to give the correct air temperature rise through the furnace as marked on the rating plate. Tempera- ture rise is the difference between supply and return air tempera- tures.
9. Furnace Maintenance FIRE, EXPLOSION, OR CARBON MONOXIDE HAZARDS Failure to have the furnace inspected and maintained could result in fire, explosion, or carbon monoxide poisoning. It is recommended that the furnace be inspected and serviced on an annual basis (before the heating season) by a qualified service technician.
10. Sequence of Operation & Diagnostics The following is the normal operating sequence for the control system. Cooling (¥) Request: 24 VAC signals applied to Y & G terminals of EFT (electronic fan timer) control. • Cool motor speed energized after 5 second Cool Fan On Delay time.
Gas Valve Diagnostic Codes (See Figure 44) OFF = Control not powered Heartbeat = Normal Operation (Standby or call for heat) 1 Flash = Not used 2 Flashes = Pressure switch closed when should be open 3 Flashes = Pressure switch circuit was still sensed as open 30 seconds after the inducer was energized.
