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
cooperation between the propane supplier and customer.

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.
