GAS SUPPLY TESTING

NOTE: This section is intended as a guide for qualified technicians installing gas to the appliance.

WARNING: Do not connect appliance before pressure testing gas piping. Damage to gas valve may result and an unsafe condition may be created.

The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of ½ psig (3.5 kPa).

The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ psig (3.5 kPa).

The gas control valve is secured underneath the firebox. Two 1/8 NPT plugged tappings are provided on the gas control valve for pressure test gauge connections (see figure 15).

GAS LINE HOOK-UP

Gas line hook-up should be done by your gas supplier or licensed service technician.

NOTE: Before you proceed, make sure your gas supply is off.

A manual shut-off valve has been included in the fireplace’s gas supply system. However, consider installing an extra shut-off valve outside the appliance’s enclosure (check with local codes), where it can be accessed more conveniently with a key through a wall as shown in figure 16.

In conformance with local codes, route a ½” NPT gas line towards the appliance coming in from either the left or right side of the fireplace (see figure 17).

CAUTION: Do not kink flexible gas line.
