Propane Gas Piping Charts
When installing a propane storage tank, the contractor must
consider proper tank sizing, safety, efficiency, ground char-
acteristics and aesthetics. For a residential customer, the
size may range from 100-1,000 gallons, depending on house-
hold use. Typically, a 500 gallon tank is ample for an aver-
age four-bedroom home. However, it is best to consult your
local propane supplier to ensure the proper sizing for pro-
pane 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 co-
operation 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 re-
quired. 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 tempera-
ture 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 fur-
nace 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 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.
Connect hot, neutral, and ground wires as shown in the
wiring diagram located on the unit’s blower door. Line polar-
ity must be observed when making field connections. Line
voltage connections can be made through either the right or
left side panel.
