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.
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.
