NOTES:Gas Type: Natural or LPInlet Pressure: 7 in. w.c. - 14 in. w.c.Max. Natural Gas Manifold Pressure: 5 in. w.c.Max. LP Manifold Pressure: 2.5 in. w.c.

External Ball Valve Shipped Loose in Control Cabinet

External High Gas Pressure RegulatorRequired when gas pressure exceeds 14 in. w.c.: P/N = 143-80-2-1-G-5/8 (10 psi. max.)

*When Optional Gas Pressure Switches are not chosen, 0-35" Inlet Gas Pressure Gauge(9) is mounted directly to Tee Fitting(5), 0-10" Manifold Gas Pressure Gauge(17) is mounted directly on the burner manifold (Not Shown) and a regular 3/4" 90° elbow is used in place of fitting (6).
