Special pipe dope must be used when assembling pip-
ing for this gas as it will quickly dissolve white lead or
most standard commercial compounds. Shellac base
compounds resistant to the actions of liquefied petro-
leum gases such as Gasolac, Static, Clyde or John
Crane are satisfactory.
Please refer to Figure 4 for typical propane gas instal-
lations.

WARNING
Failure to follow the instructions on Page
6 of this manual when the presence of
gas is suspected could result in death or
serious personal injury. An undetected
gas leak would create a danger of explo-
sion or fire.
If the propane gas furnace is installed in
an excavated area or a confined space, it
is strongly recommended contacting a
propane gas supplier about installing a
warning device to warn of a gas leak.
Propane gas is heavier than air and any
leaking gas can settle in low areas or
confined areas.
Propane gas odorant may fade, making
the gas undetectable except with a
warning device.
Vl. Electrical Wiring
WARNING
To avoid personal injury or death due to
electrical shock, disconnect the electri-
cal power before electrically connecting
the unit.
The units are designed for operation on 60 hertz current
and at voltages as shown on the rating plate. All internal
wiring in the unit is complete. It is necessary to bring in
the power supply to the contactor as shown on the unit
wiring diagram which is supplied with each unit. The 24V
wiring must be connected between the unit control panel
and the room thermostat. Refer to Figure 5 for location
of low voltage terminal board and Figure 6 for proper
thermostat wiring.
