NOTES:
1. ISOLATING RELAY MAY BE ELIMINATED IF LINE VOLTAGE
SUPPLY TO FURNACES IS THE SAME PHASE .
TO VERIFY PHASING:
A) VERIFY SOURCE IS EXACTLY THE SAME EITHER L1, L2,
OR L3 FROM THE SAME TRANSFORMER OR
B) CHECK WITH SCOPE OR PHASE METER
C) IF IN DOUBT USE RELAY
2. IF ISOLATING RELAY IS NOT USED, CONNECT FURNACE "W" TERMINALS TOGETHER.

O AVOID POSSIBLE UNSATISFACTORY OPERATION
DAMAGE DUE TO UNDERFIRING OF EQUI
/
OF NATURAL PROPANE GAS PIPING NEEDED WHEN RUNNING PIPE FROM
/
THE METER TANK TO THE FURNACE
When sizing gas line, be sure to include all appliances which
will operate simultaneously.
The gas piping supplying the furnace must be properly sized
based on the gas flow required, specific gravity of the gas,
and length of the run. The gas line installation must comply
with local codes, or in their absence, with the latest edition of
the National Fuel Gas Code, NFPA 54/ANSI Z223.1.

CFH = BTUH Furnace Input
Heating Value of Gas (BTU/Cubic Foot)
To connect the furnace to the building's gas piping, the install-
er must supply a ground joint union, drip leg, manual shutoff
valve, and line and fittings to connect to gas valve. In some
cases, the installer may also need to supply a transition piece
from 1/2" pipe to a larger pipe size.
The following stipulations apply when connecting gas piping.
• Use black iron or steel pipe and fittings for the building
piping.
• Use pipe joint compound on male threads only. Pipe
joint compound must be resistant to the action of the
fuel used.
• Use ground joint unions.
