Apply joint compound (pipe dope) sparingly and only to the male
threads of each joint. The compound must be resistant to the action
of propane gas.
Install an accessible manual shutoff valve upstream of the furnace
gas controls and within 72 in. of the furnace. A 1/8-in. NPT
plugged tapping is provided on the gas valve for test gage
connection. Installation of an additional 1/8-in. NPT plugged
tapping, accessible for test gage connection, installed immediately
upstream of the gas supply connection to the furnace and down-
stream of the manual shutoff valve, is not required. Place ground
joint union between the gas control manifold and the manual
shutoff valve.
Use the proper length of pipes to avoid stress on the gas
control manifold. A failure to follow this warning can cause
a gas leak resulting in a fire, explosion, personal injury, or
death.
Use a backup wrench at the furnace gas control when
connecting the gas pipe to the furnace to avoid damaging gas
controls or manifold.

Connect Y/Y2-terminal as shown for proper operation.
2. Some thermostats require a "C" terminal connection as shown.
3. If any of the original wire, as supplied, must be replaced, use
same type or equivalent wire.
Never purge a line into a combustion chamber. Never use
matches, candles, flame, or other sources of ignition for the
purpose of checking leakage. Use a soap-and-water solution
to check for leakage. A failure to follow this warning can
cause a fire, explosion, personal injury, or death.
Step 7—Electrical Connections

115-V WIRING

Refer to the unit rating plate or Table 5 for equipment electrical
requirements. The control system requires an earth ground for
proper operation.
Do not connect aluminum wire between disconnect switch
and furnace. Use only copper wire.
→
Make all electrical connections in accordance with the National
Electrical Code (NEC) ANSI/NFPA 70-1996 and local codes or
ordinances that might apply. For Canadian installations, all elec-
trical connections must be made in accordance with CSA C22.1
Canadian Electrical Code, or authorities having jurisdiction.
