High & LOW GAS Pressure Switches

Pressure switches sense either high or low gas pressure and automatically shut down burners if abnor- mal pressures exsist. Standard on Models 3001-4001.

Heater must be electrically grounded and bonded in accordance with local codes, or, in the absence of local codes, with the latest edition of the National Electrical Code, ANSI/NFPA 70.

ELECTRICAL WIRING

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

DANGER - SHOCK HAZARD - Make sure electrical power to the heater is disconnected to avoid potential serious injury or damage to components.

NOTE: If it is necessary to replace any of the original wiring, it must be replaced with 105° C wire or its equivalent.

ELECTRONIC IGNITION

The intermittent ignition device conserves energy by automatically extinguishing the pilot when desired tem- perature is reached. When additional heat is needed, the pilot re-ignites electrically, eliminating the fuel costs of maintaining a constant pilot. To ensure safe operation, the gas valve cannot open until the pilot relights and is confirmed.
