WARNING
Be sure to test all

to the low-pressure Natural Gas
source. This source must be regulated
to a maximum of 1/2 PSI, and the
piping must be a 3/4 inside diameter
minimum, and not be over 10 feet
in length.
3. Line up the female threaded end
of the hose with the fitting on the
heater base and tighten.

WARNING
After installing all
gas piping, and
making the proper connections, be
sure to check for leaks. Apply a 50/50
mixture of dish soap and water to all
connections. Bubbles forming are
evidence of a leak. Be sure to correct
all leaks at once!
