WEEKLY
• Drain water from storage tank.
MONTHLY
• Check your ash accumulation for best performance, remove if excessive (the size of unit,
type of oil and run time are all contingent factors).
• Change or Replace Spin-On Filter or Filter screen located in the pancake style housing (figure
14 below).
NOTE:
every application is different and may vary depending on contamination
of oils being used.
ONCE EACH SEASON (or more often, depending upon usage or contamination of oil)
• Open the burner side clean-out door to access and clean flame cone (figure 5 above,
and figure 8 below).
• Open the swing out doors on both sides of the furnace. The swing out door opposite of
the burner assembly requires the removal of the access panel allowing simple entry to the
combustion chamber and heat exchanger(s) to vacuum out the accumulated ash & soot
(hepafilter recommended) (figure 12 below).
• Clean Suntec pump filter. Remove pump cover for access (figure 13 below).
CAUTION:
Be
careful of gasket.
• Clean air compressor filter element.
YEARLY
• Clean flue pipe stack-to loosen soot remove stack at top of heater and tap thoroughly.
Then vacuum upper heat exchanger(s).
• Inspect electrode adjustment (figure 10 below). Due to erosion, adjustment may change.
• Replace nozzle every 3-5 years depending on usage (figure 5 above, and figures 9, 10 and
11 below). Will lose efficiency due to erosion. This can be accessed by swinging the burner
clean out door open (figure 8 below).
• IMPORTANT:
TO TURN POWER OFF, Remove electrical plug from heater cabinet to burner.
Remove 9/16” burner door securing nuts, swing open the burner side clean-out door.
Remove nozzle with 5/8” socket (figures 8 and 9 below).
Maintenance Schedule
BOILER
1. Clean Boiler using procedure below.
2. Check all water system piping for leaks. Repair any found.
3. Check pressure relief valve operation by opening with manual lever. If it fails to relieve,
replace immediately.
4. Check operation of safety controls, low water cutoff and manual reset high limit (if provided).
5. Check breeching connections to ensure there are no flue gas leaks. Seal any leaks found
with High Temperature Silicone Sealant.
6. Check flue gas temperature at the test point in the breeching. If gross flue gas temperature
is 550 degrees F or above, suspect that cleaning of the boiler flue-ways is required.
