GAS CONNECTION

The gas connection is a 3/8" NPT 90
line can be rigid pipe or to make installation easier,
use a listed flexible connector and/or copper tubing
if allowed by local codes. Since some municipalities
have additional local codes it is always best to
Propane
consult with your local authorities and the CAN/
#50
CGA B149 installation codes.
For USA installations follow local codes and/or the
current National Fuel Gas Code, ANSI Z223.1.
When using copper or flex connectors use only
approved fittings. Always provide a union so that
gas lines can be easily disconnected for burner
and/or valve servicing. Flare nuts for copper lines
and flex connectors are usually considered to meet
this requirement.
+/- 0.2" w.c.
+/- 0.2" w.c.
Important: Always check for gas leaks with a
soap and water solution or gas leak detector.
+/- 0.2" w.c.
Do not use open flame for leak testing.
+/- 0.2" w.c.
Note: Prior to any pressure testing of the gas
supply piping system that exceeds test
pressures of 1/2 psig, this appliance must
be disconnected from the piping system.
If test pressures equal to or less than 1/2
psig are used then this appliance must
be isolated from the piping system by
closing its individual manual shut-off
valve during the testing.

HIGH ELEVATION

This unit (at 38,000 Btu/h) is approved in Canada
for altitude 2000 ft. to 4500 ft. (CAN/CGA-2.17-M91.
with the orifice kit Part # 621-975. For Natural Gas
installations above 4500 ft. follow current CAN/
CGA-B149.1.
