MILLIVOLT - CHECKING GAS PRESSURE
and
ELECTRICAL INSTALLATION
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 ease installation, a 24" (610 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
50/50 water and soap solution 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 36.
After taking pressure
reading, be sure and turn captured screw clock-
wise firmly to reseal. Do not over torque. Check
test points for gas leaks.
Do not use open flame to check for
gas leaks.
