9GAS SUPPLY AND PIPING

Verify that the type of gas specified on rating plate is supplied to the unit. This unit is orificed for operation up to 2000 feet altitude. The appliance Btu/h output, like other similar equipment, derates approximately 4% per 1000 feet above sea level. Consult Factory for installations above 2000 feet elevation.

9.1Inlet Pressure: Measured at the inlet pressure tap located at the main gas cock. The inlet pressure must remain within the minimum flow pressure and maximum static pressure charted below while the unit is at rest and while the unit is operating at maximum firing rate.

9.2Manifold Pressure: Measure at the pressure tap on the downstream side of the final manual shutoff valve for each stage of operation. The rated manifold pressure appears on the data label. The manifold pressure is preset at the factory and adjustment is not usually required. If adjustment is required, the burner must be firing at the minimum and/or full rate while the manifold pressure is adjusted.

9.3Gas Piping Size: Use the values in “Convert Fittings To Equivalent Straight Pipe” to add the equivalent straight pipe for each elbow or tee to obtain the total distance from the meter. Use this corrected total distance from the meter for determining the suggested pipe size in the “Single Unit Installation Suggested Gas Pipe Size” table.
