Two-Speed Pumps
In some cases, the flow on the low speed is insufficient
to operate the heater. This is apparent when the pres-
sure switch cannot be further adjusted or if the heater
makes banging noises. In these cases, the pump must
be run at high speed when heating the water.
Pilot Safety
The heater employs a pilot safety which closes the
main gas valve within 8/10ths of a second whenever
the pilot flame is interrupted. Pilot flame is automatical-
ly lit when the device is powered. Unit performs its own
safety check and opens the main valve only after the
pilot is proven to be lit.

NOTE: If heater is installed outside of the limits
shown, a flow switch must be used in place of the
pressure switch when mounted and wired adjacent
to the heater.
CAUTION: Do not operate the heater without the
function of a properly adjusted pressure switch.
CAUTION: Propane gas is heavier than air and
sinks to the ground. Exercise extreme care in lighting
heater in confined areas.
