Note. When the heater is started for the
first time after installation, or at the
beginning of the heating season, air trapped
in the fuel lines may prevent sufficient fuel
from reaching the heater on the timed
ignition cycle. If the indicator lamp does not
light after three minutes, turn control switch
to OFF position. Check the reset button in
the control box. Wait five minutes; then
restart heater. If the heater still does not
operate properly, shut the unit off and check
for the difficulty, following instructions in
maintenance and repair.
b. Stopping. The heater stops automatically when
the proper temperature is reached. Placing the control
switch in "OFF" position stops heater operation. The
heater will continue to operate, and the indicator lamp
will glow, for approximately two minutes after shutdown.
