gas line and test all gas joints from the gas meter to the
fi replace 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 20.
After taking pressure reading, be sure and
turn captured screw clockwise fi rmly to reseal. Do not
over torque. Check test points for gas leaks.
