result in lower performance for the Coal Gun.
Annual cleaning will help maintain like new
performance.
Square Swirl Tube Exit Port
To clean through this opening with a vacuum
hose, choose a hose that represents the largest
diameter that will pass easily through the hole. Work
the hose into the opening, then withdraw it with the
vacuum running. Repeat the insertion and removal
several times.
Hose Inserted into Swirl Tube Heat Exchanger
Cleaning Rear of Heat Exchanger
It is also recommended to clean the heat
exchanger from the rear of the boiler annually. /is
is accomplished by removing the fan assembly, then
vacuuming and/or scraping the exposed surfaces of
the 1re tubes and swirl tube. Removing the fan
assembly requires removing the nuts from the
mounting bolts as shown in the following photo.
Removing Fan Assembly
Once the nuts are removed, carefully pull the fan
assembly back directly oD the mounting bolts, and
set the fan assembly oD to the side. /e wiring
harness for the fan is too short to allow se ing the
fan assembly directly on the @oor, so a 1ve gallon
bucket or other temporary platform will be needed.
As an alternative, you may disconnect the wiring
harness from the motor, giving you more freedom
about where you place it. Doing so is necessary for
other maintenance tasks. Be sure to note proper
connections for rea aching the fan assembly. Do not
drop the assembly. Handle it carefully, as the ceramic
heat shield is fragile, and becomes increasingly
fragile over many heating/cooling cycles. It is a good
idea to keep a spare.
Set Aside Fan Assembly for Heat Exchanger Access
Once the fan assembly is out of the way, you will
have access to the 1re tube and rear of the swirl tube
