5, 6, 7. Use ground joint unions and install a drip leg no less than 3" long to trap dirt and moisture before it can enter gas control valve inside furnace. Provide a 1/8" NPT plugged tapping for test gauge connection immediately up stream of gas supply connection to furnace.
Typical Gas Piping ('aMP) 25-25-02 Piping with Street Elbows 1. Screw one elbow onto gas valve with the outlet facing away from the furnace. 2. Screw second elbow onto first elbow tight enough to be leak proof. An additional 1/4 turn will be required at the end of step 2.
9. Electrical Wiring ELECTRICALSHOCK HAZARD. Failure to follow safety warnings exactly could result in death or personal injury. Turn OFF electrical power at fuse box or service panel before making any electrical connections and ensure a proper ground connection is made before connecting line voltage.

ous-fan option. This connection is intended for the low speed mo- tor tap, and has a lower contact rating (8 amps) than the heat and cool taps. When the low speed blower lead is connected to this terminal, this will provide low speed blower operation whenever the other two speeds (Heat or Cool) are not energized.
14. Sequence of Operation & Diagnostics The following is the normal operating sequence. Cooling (¥) Request: 24VAC signals applied to Y & G terminals of FCB (furnace control board) • Cool motor speed is energized after 5 second Cool Fan On Delay time.
Heating Request with Gas Shut Off: 24 VAC signal applied to W terminal of FCB. The FCB will attempt 4 cycles for ignition then go to soft lockout for 3 hours then try for ignition again as long as the heat call remains. Power reset will clear lockout.
