CONNECTING THE GAS
NOTICE: A qualified gas appliance installer must connect the heater to the gas supply. Consult all local codes.
CAUTION
Use new black 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. See Figure 17.

IMPORTANT: Loosen the pipe adapter on the flex tube before installing to the system piping.
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 mode.
Always use an external regulator for all propane/L.P.G. heaters and high pressure one 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.
