The stainless flex line is on the right side facing the fire-
place and can connect to either a 3/8 NPT female or 1/2
NPT male pipe. To connect from the opposite side, route
the pipe under the rear portion of the unit.

for leaks using a gas analyzer or soap and water solution
after completing connection. DO NOT USE AN OPEN
