NOTE:
This heater is equipped with a fan delay switch
which delays the fan operation until the heating grid has
heated sufficiently to assure the circulation of only warm air.
This same switch permits the fan to operate after power to
the grid has been shut off by thermostat action, thus utilizing
all the heat remaining in the grid.
When the heater is shut down by turning the switch OFF,
power to both fan motor and element is diconnected and the
fan motor will not continue to operate.
WARNINg:
Should the OVERTEMP light come on,
disconnect power to the heater, turn the switch OFF or
turn down the thermostat fully counterclockwise and call
a licenced electrician. DO NOT USE HEATER UNTIL
PROBLEM IS DETERMINED AND FIXED.

or OFF.
This heater requires no maintenance other than a cleaning at least
once a year.
