A typical gas supply line might consist of ½” piping
beginning at the gas supply source. This line will be routed,
within the shortest possible distance, up to the vicinity of
the heater location (30 Ft. MAX). This line, as previously
mentioned, willhave a ½” lever- handled gas shut-off
valve installed in-line, and within 6-feet of the termination
point. After final heater positioning and mounting angle is
created, the pipe line is then routed directly to the ½” NPT
(female) coupling at the end of the heater. As an alternate
to this installation, after the gas line has been routed to
the vicinity of the heater, and after final positioning and
pivot angle has been determined, a short gas flex line can
be installed from the end of the hard pipe to the ½” NPT
(female) coupling on the heater. This flex line should be
1/2” I.D. (5/8” O.D.), Stainless Steel, with ½”MIP fittings at
both ends. A ½” FIP coupling will then be used to connect
the flex line to the hard pipe. The use of this flex line allows
for additional angle (pivot) adjustment of the heater after
installation has been complete.
GAS LINE PURGING
You should purge the gas line of air before attempting to
light the heater.
• Slowly turn on the main gas supply.
• With the gas on, loosen one connection near the
heater until you either ‘hear’ gas or ‘smell gas’. Tighten
connection immediately. This should purge the remaining
air from the lines.
