INSTALLATION - Cont’d.
STEP 2.
ROUGH IN GAS SUPPLY – (See Figure 3)
a) Select the bottom, rear or right side to bring the factory supplied flexible gas line assembly out of
the heater.
b) The valve must be connected only by means of a pipe union of the ground joint type.
Mr. Installer, hold gas valve when connecting gas supply line.
c) Install at least a 3/8” gas line. Contact local gas supplier if any questions.
d) Install a drip leg in gas supply line immediately upstream from the gas connection to heater, (see
local codes), and provide a 1/8” N.P.T. plugged tapping, accessible for test gauge connection and a
individual manual shut off valve accessible within room where heater is installed. The heater and
its individual shut off valve must be disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of ½ psig (3.5Pa). The heater must be
isolated from the gas supply piping system by closing its individual manual shut off valve during any
pressure testing of the gas supply piping system at test pressures equal to or less than ½ psig
(3.5Pa).
e) Test all connections for leaks using a soapy solution. NEVER USE AN OPEN FLAME TO TEST
FOR LEAKS.
f) The maximum inlet gas supply pressure for natural and L.P./Propane gas is ½ p.s.i. or 14” w.c.
The minimum inlet as supply pressure for the purpose of adjustment is 4.5” w.c. for natural gas
and 11.0” w.c. for L.P./Propane gas.
