WARNING
To prevent death, serious personal in-
jury or property damage due to fire or
explosion caused by a propane gas leak,
install a gas detecting warning device.
If the propane gas furnace is installed in
a basement, an excavated area or a con-
fined space, a warning device is required
due to:
• Propane gas is heavier than air and
any leaking gas can settle in any low
areas or confined spaces.
• Propane gas odorant may fade, mak-
ing the gas undetectable except with
a warning device.
If the presence of gas is suspected, fol-
low the instructions on Page 2 of this
manual.

When servicing controls, label all wires
1,900
before disconnecting. Wiring errors can
1,700
1,500
cause improper and dangerous oper-
ation. After servicing is completed, al-
ways verify proper operation.
The unit wiring harness is an integral part of the furnace.
Field alteration to comply with electrical codes should not
be required.
Power supply to the furnace must be NEC Class 1, and
1,417
must comply with all applicable codes. The furnace must
1,275
1,066
be electrically grounded in accordance with the local
976
codes or, in their absence, with the latest edition of the
866
787
National Electrical Code, ANSI NFPA No. 70 and/or the
665
590
CSA C22. 1 Electrical Code. A fused disconnect must be
provided and sized in accordance with the unit maximum
overcurrent protection.
Typical Field Wiring
(24 VAC Control Circuit)
A 40 V.A. transformer and an integrated electronic con-
trol are built into the furnace to allow use with most
cooling equipment.
CAUTION
To avoid the risk of electrical shock,
wiring to the unit must be properly polar-
ized and grounded.
To provide more reliable sensing of flame, the ground
wire must run to the electrical panel.
Line voltage wiring must enter into the junction box
provided with the furnace.
