bleed from the gas system.

qualified service person or gas sup-
plier for repairs.

seconds, release control knob.

OPERATION
The control knob can be set to any heat level
between HI and LO. When the room tem-
perature exceeds the set temperature, the
burner will cycle to pilot. The burner will
cycle back on when room temperature drops
below the set temperature. Selecting a higher
setting will cause the heater to run longer,
producing greater heat output. At lower
settings, the heater will run less.
Note: The thermostat sensing bulb mea-
sures the temperature of air near the heater
cabinet. This may not always agree with
room temperature (depending on housing
construction, installation location, room size,
open air temperatures, etc.) Frequent use of
your heater will let you determine your own
comfort levels.
