DESCRIPTION OF CONTROLS IN GENERAL
ENERGY SAVING PUMP CONTROL
The energy saving pump control is an electronic
device that allows the operator to set the desired time for
the pump to run after the heater shuts off. The time is
factory-set at 7 minutes and it can be re-adjusted in the
field anywhere from 3 to 10 minutes.
In a conventional system, when the tankstat is
satisfied, the main gas valve closes, but the pump
continues operating. With the energy saving pump
control, the heater pump is programmed to continue
running for an optimum period of time in order to absorb
the residual heat from the combustion chamber and use
it in the system.
The pump then shuts off until the next call for heat is
received from the tankstat.

Ignition Module Electronic Safety
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 costs of maintain-
ing a constant pilot. To assure safe operation, the gas
valve cannot open until the pilot lights and is proven.
