CHECK GAS PRESSURE – IPI
1. Check gas type. The gas supply must be the same as
stated on the appliance's rating decal. If the gas supply
is different from the fireplace, STOP! Do not install the
appliance. Contact your dealer immediately.
2. To facilitate easier installation, a 18" (610 mm) flex line
with manual shut-off valve has been provided with this
appliance. Install and attach 1/2" 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 50/50 water and
soap solution or a gas sniffer.
4. To check gas pressures at valve, turn captured screw
counter clockwise 2 or 3 turns and then place tubing
to pressure gauge over test point. Turn unit to high.
Figure 21. After taking pressure reading, be sure and
turn captured screw clockwise firmly to reseal. Do not
over torque. Check test points for gas leaks.
DO NOT use open flame to check for gas leaks.
