7GAS 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. Appliance Btuh output derates 4% per 1000 feet elevation above sea level. Consult Factory for installations above 2000 feet elevation.

7.1Gas Train and Controls Certification

NOTE: The gas train and controls assembly provided on this unit have been tested under the applicable American National Standard to comply with safety and performance criteria such as proper ignition, combustion and safety shutdown operation.

7.2Gas Control Trains

All models include gas control trains with the following components: main manual shutoff valve, two safety shutoff valves, proportionator regulator and a final manual valve with the manifold pressure tap on the side of the valve. These components may be separate or two or more may be combined in a common housing.

Caution: Do not adjust or remove any screws or bolts on gas train control components which are sealed with a red or blue colored compound. Doing so will void all approvals and warranties.

7.3Inlet Pressure

Measure at the inlet pressure tap located at the main gas cock. The inlet pressure must remain within the minimum and maximum values while the unit is at rest and while the unit is operating at maximum firing rate.
