INSTALLATION
Gas piping
A minimum pipe size of 1/2" is required for inlet piping. A 1/2" lever handled shut-off gas cock
should be installed within 6 feet of the appliance for servicing the unit. Check with local and
state plumbing and heating codes regarding sizing of the gas lines. Installation of a drip leg
in the gas supply line going to each heater is required to minimize the possibility of any loose
scale or dirt within the gas supply line from entering the heater’s control system. A 1/8" NPT
plugged test gage connection is required immediately upstream of the gas supply connection
to the heater.
Do not block air inlets or restrict airflow to the air inlets.
