Installation, Operation, And Service Instructions

 

 

 
 
 

WASTE OIL BURNER: 

1. 

Weekly 

 Drain water from storage tank. 

2. 

Monthly 

Clean pump screen on oil pump assembly of sludge and remove 

any water.  Access to screen is by removing pump cover.  Clean flame 
cone of deposits.  

3.

 

Yearly

  Inspect and adjust electrodes per (figure 37). 

CAUTION: turn off 

main electrical power before checking or adjusting electrode 
settings.  

Inspect and check alignment of nozzle in relation to flame 

cone/burner tube (figure 37).  Tip of nozzle must be 1/4” forward of inside 
radius of flame cone.  If nozzle is behind inside radius of flame cone, 
coking will occur and flame cone can clog.  To adjust, loosen Pre-Heater 
block securing nut and set screw, push fore or aft as needed then 
retighten securing nut and set screw.

 

 

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 
flueways is required. 

BOILER CLEANING: 

Turn off the power with the line switch.  Disconnect the electrical plug at the J-Box by 
the Aquastat Relay.  Remove the four hex head bolts from the outer corners of the burner 
mounting plate and swing open the burner door with burner mounted to provide access to 
the boiler flueways.  Remove sludge and deposits from Stainless Steel Insert.   When all 
deposits are removed, close burner door,  and plug in the electrical lead, restore the power 
and turn burner on.  If a boiler is to be shut down and taken out of service for a period of 
time, the boiler should be cleaned immediately upon shut down while the flueways are 
still warm.  When the boiler gets cold, the deposits harden making cleaning difficult.  
Further, hardened deposits will absorb moisture and cause corrosion. 
 

 

 
 
 
 
 
 
 
 

MAINTENANCE 

IMPORTANT 

It is essential that the boiler be cleaned on an annual basis, even if no soot is present.  

Sulfer, and other deposits which may be present, can cause severe corrosion damage 

if they are not removed periodically.
