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.
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
WARNING
!
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.
