" gas line onto shut-off valve.
3. After completing gas line connection, purge air from
gas line and test all gas joints from the gas meter to
the fireplace for leaks. Use a solution of 50/40 water
and soap or a gas sniffer.

counter clockwise 2 or 3 turns and then place tubing to
pressure gauge over test point. Turn unit to high. See
