3.0 Installation • Gas Supply
Form the stainless steel flexible connector into a smooth C-shape allowing 12 in. between the flexible
2
connector's end nuts (see Figure 3.29).
Attach the ball valve to the gas supply pipe. Apply pipe compound to NPT adapter threads to seal the
3
joint. Use only a pipe compound resistant to LP. NOTE: Provide a 1/8 in. NPT plugged tapping
accessible for test gauge connection immediately upstream of gas connection to the heater (provided
on ball valve).
When using a stainless steel flexible gas connector, do not attach the connector nuts directly to the
gas pipe supply. Connector nuts must be installed to an approved adapter.
Attach the flexible connector to the adapter and burner control box inlet. Seal the joints.

NOTE: Excessive torque on the manifold may misalign the orifice. Always use two wrenches to
tighten mating pipe connections.
Final assembly must be tested for gas leaks according to NFPA 54 and all local codes and/or
5
Standards.
Testing for gas leaks with an open flame or other sources of ignition may lead to a fire or
explosion and cause serious injury or death. Test in accordance with NFPA or local codes.
