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 replace, STOP! Do not
install the appliance. Contact your dealer immedi-
ately.
. To ease installation, a 4" (610 mm) ex line with
manual shut-off valve has been provided with on
this appliance. Install and attach 1/" 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 replace for leaks. Use a solution of 50/50
water and soap solution or a gas sniffer.
4. To adjust ame 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  or 3 turns and then place
tubing to pressure gauge over test point. Turn unit
to high. Figure 47 After taking pressure reading,
be sure and turn captured screw clockwise rmly
to reseal. Do not over torque. Check test points for gas
leaks.
