0 3.RUN GAS LINE FROM ITS SOURCE TO
THE HEATER
If gas piping from the source to the heater loca-
tion has not been accomplished, install the
required pipe. Consult local plumbing code to
assure proper pipe size.
The gas pipeline can be brought in through the
right side of the heater.
NOTE: The gas line connection can be made with
properly tinned 3/8" copper tubing, 1/2" rigid pipe
or an approved flex connector, then reduced to
3/8" to the heater. Because some municipalities
have some additional local codes, it is always
best to consult your local authority. Consult the
current National Fuel Gas Code, ANSI Z223.1
A
Always check for gas leaks with a mild
soap and water solution. Do not use
an open flame for leak testing.
The gas control is equipped with a captured
screw type pressure test point, therefore it is not
necessary to provide a 1/8" test point up stream
of the control.
