1. Remove and CLEAN the gas gas gas gas gas
line strainers line strainers line strainers line strainers line strainers. Make certain
gas valves
gas valves gas valves gas valves gas valves are CLOSED and that
gas is purged from the system be
fore attempting disassembly.
2. Inspect the collector plate collector plate collector plate collector plate collector plate at
the top of the burner casting
and the burner cup
burner cup burner cup burner cup burner cup for any ac-
cumulation of foreign material.
CLEAN if required. Foreign ma-
terial in the burner cup or cast
ing will not burn out and will im-
pair burner operation.
3. If required, inspect ignitor plug ignitor plug ignitor plug ignitor plug ignitor plug
and CLEAN the electrodes electrodes electrodes electrodes electrodes.
Use an ignition point file to re-
move carbon and rust between
the electrode surfaces

Note: Do not allow high moisture ma-
terial to collect within the trough area.
It may adversely affect metal parts.
8. Inspect entire dryer for loose,
worn or damaged parts. Include
check of auger flighting, me-

sulated clamps, and do not
chafe on other metal parts.
9. Make sure all dryer guards dryer guards dryer guards dryer guards dryer guards and
warning decals warning decals warning decals warning decals warning decals are securely in-
stalled. Make certain guards do
not interfere with moving parts.
If guards or warning decals are
missing, contact your dealer for
a free replacement.
10. TEST FIRE the dryer dryer dryer dryer dryer several
weeks ahead of the drying sea-
son. CHECK for possible gas
