Typical Gas Line Connection
Step 1: With the engine assembly free from the fireplace,
check tightness of flexible connector fittings.
CAUTION: Use one wrench to hold regulator and one
wrench to loosen and tighten the brass fittings. Failure to
hold the regulator while loosening and tightening the
fittings can damage the unit and cause gas leaks.
Step 2: Set the engine assembly into the fireplace and connect
the flexible connector to the gas piping that has been installed
per local codes, or in the absence of local codes, ANSI Z223.1
latest edition.
Step 3: After the last connection is made, screw the engine
assembly to the bottom of the fireplace. (Fig. 3)
Step 4: Test all connections for gas leaks.

Under no circumstances should internally zinc alloy coated piping be used. According to the LP-Gas Code and National Fuel Gas
Code - If galvanized piping is used, it must be EXTERNALLY coated only! Galvanized water pipe used for gas installations will
result in reduced gas pressure and gas leaks.
