4. Inspect flame sensors for pos-
sible damage or poor connec-
tions. Flame sensor wires must
be in good condition.
5. Inspect and manually rotate the top
auger paddle assembly. The paddle
unit must rotate freely without any
indication of sticking or binding.
6. Inspect the top auger and bottom
auger drive lines for proper adjust-
ment and condition. Readjust line
tension as required.
Note: All of the auger and me-
tering roll bearings are lifetime lu-
bricated and do not require service
relubrication.
7. Operate dryer clean out levers,
and check cleanout hatch mecha-
nism for proper operation. With
hatch open, inspect and remove
anyaccumulation of dirt, fines
and foreign material from the
bottom auger trough area.
Note: All of the auger and me-
tering roll bearings are lifetime lu-
bricated and do not require service
relubrication.
1. Remove and clean the gas line
strainers. Make certain gas valves
are closed and that gas is purged
from the system before attempting
disassembly.
2. Inspect the collector plate at the
top of the burner casting and
the burner cup for any accumu-
lation of foreign material. Clean
if required. Foreign material in
the burner cup or casting will not
burn out and will impair burner
operation.
3. If required, inspect ignitor plug and
clean the electrodes. Use an igni-
tion point file to remove carbon and
rust between the electrode sur-
faces. Ignitor gap should be about
1/8 inch.
Note: Do not allow high mois-
ture material 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, metering rolls and
other internal parts. Check that tem-
perature sensors within air ple-
num chamber are secured within
insulated clamps, and do not
chafe on other metal parts.
9. Make sure all dryer guards and
warning decals are securely in-
stalled. Make certain guards do not
interfere with moving parts. If guards
or warning decals are missing, con-
tact your dealer for a free replace-
ment.
10. Test fire the dryer several weeks
ahead of the drying season. Check
for possible gas leaks. See page
16 for burner test fire.
