Re: Pictorial of All DF520 Stoker Parts and Assemblies

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

Turn off all electricity to the unit and disconnect the motor wires.

Loosen the allen screw that attaches the motor coupling to the gearbox shaft. Remove the 3 bolts that hold the motor cover to the fan housing. Pull straight out. If you have the old style coupler, just remove the 3 bolts and pull straight out. If the cover won't pull straight out, gently use a chisel to move the cover away from the fan housing.
