Cleaning of Burnpot Parts
Cleaningcanbeperformedin2basicways:
1.Becausethecornslagbuildupwillabsorbmoisturefromthe
airwhencool,thepartscanjustbeleftexposedforseveral
daysandtheslagbuildupwillcrumbleoffoftheparts.
2.To accelerate this process,theparts can be soaked in
water for approximately 30 minutes (depending on the
amountofbuildup,theycouldbecleanedinlesstime).
NOTE:Cleaningof thesepartsisnotnecessaryuntilyou
seethatthereisanoticeabledecreaseinthequalityofthe
ameintheburnpot.Example:Unburnedfuelbeingpushed
