CONNECT GAS LINE
WARNING
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 sul
fi
de 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
fl
ow
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. 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.
NOTICE:
A quali
fi
ed gas appliance installer must connect the heater to the gas supply. Consult all local codes.
IMPORTANT:
Hold heater valve
fi
rmly 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. 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.
