SERIES 2000 HEATER OPERATING PROCEDURE
Adjusting the vaporizer coil on a liquid propane model. The top photo
shows the setting in, and the bottom photo shows the coil out.
ADJUSTING THE
VAPORIZOR
The display will indicate "FLAME"
when flame is sensed. If no flame
is sensed, the "FLAME" message
will be off. The display indicates
what part of the cycle it is in. If the
unit is a hi-lo dryer, the display will
indicate whether it is in the "HI-
FLAME" or "LO-FLAME" part of the
cycle. (see "programming set points"
page 17 for setting the hi-lo flame
temperature). If the temperature is
above the high temperature setting,
the flame will be off, the "FLAME"
message will be out and the display
will be flashing "OFF-CYCLE".
If the flame is shut off because
of the humidity sensor (humidistat),
the display flashes "OFF-CYCLE
HUMIDISTAT".
RUNNING THE DRYER
1. Vaporizer should be adjusted so
the vapor pipe train runs warm
to the touch (100
°
-120
°
F).
2. Loosen 5/16" bolt on adjustment
bracket.
3. Swivel vaporizer away from
flame if running too hot, closer
to flame if too cold.
4. Move vaporizer only 1" at a time
and allow a few minutes for tem-
perature to equalize.
5. Tighten 5/16" bolt and watch
heater run for several minutes
to verify adjustment.
