NOTICE: A qualified gas appliance installer must connect the heater to the gas supply.
Consult all local codes.
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 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 10
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 11
