CHECKING GAS PRES SURE 
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" (mm) flex line with manual 
shut-off valve has been provided with on this appli-
ance. Install and attach 
3
/
8
" 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. NOTE: To make the 
process of checking the gas pressure easier, unfasten 
the two screws which secure the gas valve to the side 
of the firebox and bring forward. [Remove the glass 
to allow the valve to come forward. (See page 29 for 
glass removal.)] When done, you must refasten the gas 
valve into place. 
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.  See 
Figure 25. 
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 fl ame to check for 
gas leaks.
