Installation of the Gas Line to the Heater
1
Install a sediment trap / drip leg in the supply line at the lowest spot prior to the gas ball valve. The trap
length shall be at least three inches long. Ideally, the trap would be installed as close as possible to
the shut off.
2
Install manual shut off ball valve with optional 1/8” NPT Test connection towards the supply line. The
manual shut off ball valve must be located within 6 feet of the appliance’s service access door.
3
Install the 5/8 inch flare to ½” NPT adapter piece downstream of the gas valve as shown in Figures
3.14-3.15. This piece is typically included with the flexible gas connector, loosely installed on one of
the flare nuts.
NOTE:
Keep flare surfaces clean and free of sealing compounds. Only the pipe threads
require sealing compounds.
4
Form the 1/2” x 24” stainless steel flexible gas connector into a smooth C-shape, allowing
approximately 12 inches between the flexible connector’s end nuts (see Figure 3.15). The connector
must reach from the gas supply to the appliance without stretching, kinking, or twisting.
5
Attach the flexible connector to the 5/8” flare adapter on the gas line and the other end to the 5/8”
flare on the heaters inlet pipe.
DO NOT
connect the connector flare nuts directly to pipe threads. Use
only the adapters provided. DO NOT kink, twist, or over-torque the connector when installing.
