CONNECT GAS LINE
NOTICE: A qualified gas appliance installer must
connect the heater to the gas supply. Consult all local
codes.
Use new black iron or steel pipe. Internally
tinned copper or copper tubing can be
used per National Fuel Code, section 2.6.3,
providing gas meets hydrogen sulfide limits,
and where permitted by local codes. Gas
piping system must be sized to provide
minimum inlet pressure (Listed on Data
Plate) at the maximum flow rate (BTU/hr).
Undue pressure loss will occur if the pipe
is too small.
A manual shutoff valve must be installed
upstream of the appliance. Union tee
and plugged 1/8" NPT pressure tapping
point should be installed upstream of the
appliance. Figure 9
A sediment trap should be installed upstream
to prevent moisture and contaminants from
passing through the pipe to appliance
controls and burners. Failure to do so
could prevent the appliance from operating
reliable. Figure 9

IMPORTANT: Hold heater valve firmly with a wrench to
prevent movement when connecting to inlet pipe.
Always use an external regulator for all propane/LPG
heaters and high pressure one to two-pound systems
only, to reduce the supply tank pressure to a maximum of
13" w.c. This is in addition to the internal regulator in the
heater valve.
CHECk GAS TYPE: The gas supply must
be the same as stated on the heater's rating
plate. If the gas supply is different, DO NOT
INSTALL THE HEATER. Contact your dealer
for the correct model.
