4. Remove and clean lower burner shields as shown in
Figure 8
. This can best be accomplished with a
scraper.
5
Blow out all four (4) burners through the venturi opening.
CAUTION: Do not drop burners or get
wet as this may break gasket or add to premature burner failure.
6. Reassemble conveyor chain. Make certain it is not on backward (
Figure 6
) and
CLOSE
open links to
match other links.
7. Using a damp cloth, wipe the inside of each burner venturi.
8. Reinstall burner screens, lower burner shields, and burners.
QUARTERLY CLEANING PROCEDURES & PREVENTIVE MAINTENANCE
1. Remove conveyor and soak in hot soapy water overnight. The chain is removed by lifting axle up to
produce slack and separating as described in Item 3 above. When replacing chain, make certain the
conveyor is installed per
Figure 6
. PLACING CHAIN ON BACKWARD WILL CAUSE SEVERE
BINDING PROBLEMS. CLOSE open links to match other links.
2. Lubricate the roller (drive) chain with a few drops of any grade motor or machine oil.
3. Remove and inspect all motor brushes and replace if less than 1/4" is left.
4. Do not remove internal gas lines for cleaning.
5. Clean gas orifices:
• Orifices are passageways directing gas flow into burner. Uneven gas
flow or air to gas ratio is caused by dirty or damaged orifices.
• Orifices are made of brass. Use special care in cleaning—don't gouge
or make gas holes bigger.
• To reach orifices, remove burners.
• Use a pipe cleaner dipped in rubbing alcohol to clean orifices. Swab
until clean; free of carbon build-up. Do not use drill bit; this damages
orifice.
6.
INVENTORY THE SPARE PARTS KIT AND ORDER MISSING PARTS AS NEEDED. KEEP A
COMPLETE SET OF PARTS ON HAND AT ALL TIMES.
