Optional Outside Combustion Air Supply Installation; Gas Supply Line; Electrical Supply - Regency U31 Owners & Installation Manual

OPTIONAL OUTSIDE COMBUSTION AIR SUPPLY
A 4" (100 mm) dia. aluminum flex pipe or equivalent may be installed from the outside (with a proper exterior cover) to the Zero
Clearance cabinet. There are outside holes provided on three sides of the kit. Use only the one that is most suitable for your
installation. This will provide adequate outside combustion air supply to the heater.
An authorized service person should install the gas line in accordance with all local building codes. If codes permit, flex gas
line or coiled copper tubing may be used as gas supply line. The suggested way to install the gas supply line is as follows:
run 1/2" (9.5 mm) NPT gas line to the left side of the framed opening. (See U31/I31 installation instructions for additional
information).
