MILLIVOLT CHECK GAS PRESSURE
1. Check gas type. The gas supply must be the same as
stated on the appliance’s rating decal. If the gas sup-
ply is different from the fireplace, STOP! Do not install
the appliance. Contact your dealer immediately.
2. To ease installation, a 30" (762 mm) flex line with
manual shut-off valve has been provided with on 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 50/40 water
and soap or a gas sniffer.
4. To adjust flame height, turn HI/LO knob to HI to get
maximum pressure to burner. Turn HI/LO knob to LO
to get minimum pressure.
5. 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 43.
After taking pressure reading, be sure and
turn captured screw clockwise firmly to reseal. Do not
over torque. Check test points for gas leaks.
