to inspect the ue passages of the boiler unless the technician
suspects damage or malfunction.
Boilers Firing on #2 Oil, B100 Bio-Diesel, Digester
Gases or Any Other Substance Besides Natural
Gas or Propane
Inspect the duplex stainless steel ue passages every 4,000
hours of operation (not including hours operating on Natural
Gas or Propane). This is the bottom section of the heat
exchanger and will not require removal of the burner or fuel
train.
Procedure for Accessing the Duplex Stainless
Steel Flue Passages (all models)
1. Lock out the power supply to the boiler and isolate the
fuels supplied to the unit.
2. Remove the front lower jacket panel from the boiler.

4. If deemed necessary, clean the ue passages with the
proper equipment, such as round wire brushes and a
wet/dry shop vacuum or soot vacuum system.
5. Insert the turbulators back into position.
6. The ue passage cover gasket must be replaced. Do not
reuse the gasket.
7. Reinstall the ue passage cover. Conrm torque to 23 ft/
lbs (31.2 NM) on all bolts. Do not replace any bolts, nuts,
washers or other components without consulting the

9. Fire the boiler and set combustion to proper levels.
10. To conrm proper seal on the door after this procedure
has been conducted, ensure there are no ue gases
present around the boiler once unit is running.
11. If evidence of extensive soot, scaling or corrosion is
present in the duplex stainless steel ue passages, this
may indicate that removal of the burner and cleaning
of the furnace and upper ue passages is required.
