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.
