household use. Typically, a 500 gallon tank is ample for an
average four-bedroom home. However, it is best to consult
your local propane supplier to ensure the proper sizing for
propane storage requirements. Determining the correct tank
size for each household is a function of demand, economy,
efficiency and convenience. It is a process that requires
cooperation between the propane supplier and customer.

1,900 purposes. Refer to the wiring diagram for wire routings. If
1,700
any of the original wire as supplied with the furnace must be
1,500
replaced, it must be replaced with wiring material having a
temperature rating of at least 105° C. Any replacement wir-
ing must be copper conductor.
115 VOLT LINE CONNECTIONS
Before proceeding with electrical connections, ensure that
the supply voltage, frequency, and phase correspond to that
specified on the unit rating plate. Power supply to the fur-
nace must be N.E.C. Class 1, and must comply with all
applicable codes. The furnace must be electrically grounded

Use a separate fused branch electrical circuit containing
590
properly sized wire, and fuse or circuit breaker. The fuse or
circuit breaker must be sized in accordance with the maxi-
mum overcurrent protection specified on the unit rating plate.
An electrical disconnect must be provided at the furnace
location.
NOTE: Line polarity must be observed when making field
connections.
