Maintain Burner’s
Fuel Filter/Water
Separator
Drain water from burner’s filter bowl before
each use and replace filter after every 500
hours of use or as needed.
1) After each use of the burner, visually
check the filter bowl. If any water has
accumulated, drain it via the water drain
at the bottom of the bowl.
2) After every 500 hours of operation,
empty the burner’s fuel tank to remove
the filter bowl and inspect the fuel
filter/water separator. Replace filter as
needed.
Important: Always empty the burner’s fuel tank
before removing the filter bowl. There is no shut-
off valve between fuel filter/water separator and
burner’s fuel tank.
Descale Heating Coil
Descale coil tubing annually or more frequently as needed.
In hard water areas, scale can build up inside the heating coil tubing.
Scale deposits will decrease the output pressure and temperature of
heated spray and may eventually clog water flow through the heating
coil.
Descale the coil tubing at least annually and more frequently if you
detect a decrease in output pressure or temperature.
To descale the coil:
1) Mix a commercial coil cleaner in a 5-gallon bucket and elevate
the bucket so it is higher than the unloader. If you are using a
feed tank, fill the tank with enough solution to cover the supply
bulkhead by 2” or more. This will ensure air is not drawn into
the pump.
2) Attach the high-pressure hose(s) to the high-pressure water outlet on the machine. Do not hook up the spray gun.
3) Place the other end of the high-pressure hose(s) in the 5-gallon bucket.
4) Attach the 1" Hose to the inlet on the pump.
5) Prime the pump by filling the hose with water, then placing the end of the hose in the bucket.
6) Run the pressure washer in cold mode for 1 to 3 hours, recirculating the cleaning solution.
7) You may need to top off the bucket with more solution once the lines are full.
WARNING: DO NOT RUN THE BURNER. The chemical used to descale could have an adverse effect and emit
harmful vapors or fumes.
8) Dispose of the cleaning solution where it is not harmful to animals or the environment.
9) Flush with fresh water and clean the inlet strainer when finished.
Clean Combustion
Head Flame Senor
Lens
Clean combustion head flame sensor lens every 100 hours. If the
flame sensor lens gets sooted up the flame sensor will not be
able to sense a flame therefore the burner will not fire.
