PRODUCT DESIGN
31
When installing a propane storage tank, the contractor
must consider proper tank sizing, safety, efficiency, ground
characteristics and aesthetics. For a residential customer,
the size may range from 100-1,000 gallons, depending on
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.

WIRING HARNESS
The wiring harness is an integral part of this furnace. Field
alteration to comply with electrical codes should not be
required. Wires are color coded for identification purposes.
Refer to the wiring diagram for wire routings. If any of the
original wire as supplied with the furnace must be replaced,
it must be replaced with wiring material having a temperature
rating of at least 105° C. Any replacement wiring 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
furnace must be N.E.C. Class 1, and must comply with all
applicable codes. The furnace must be electrically grounded
in accordance with local codes or, in their absence, with the
latest edition of The National Electric Code, ANSI NFPA 70
and/or The Canadian Electric Code CSA C22.1.
Use a separate fused branch electrical circuit containing
properly sized wire, and fuse or circuit breaker. The fuse or
circuit breaker must be sized in accordance with the maximum
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.
