3. Place a shop rag beneath the fuel pump to catch any
spilled fuel oil, and then remove the fuel pump cover.
To do this, use a 4-mm Allen wrench to remove the
four bolts that secure the cover to the fuel
pump/blower assembly.
Remove the fuel pump cover
4. Remove the fuel pump screen.
Remove the fuel pump screen
5. Inspect the screen for damage. If the screen is not
damaged, proceed to step 6. If the screen is bent,
torn, cracked, or damaged in any way, discard it and
skip to step 7 with a new fuel pump screen.
6. Rinse the screen in the 1/4 cup of clean fuel oil. If
necessary, gently scrub the screen with the nylon-
bristled brush (a toothbrush works well) to remove
any debris or buildup.
7. Replace the screen and fuel pump cover. Tighten the
bolts snugly. Wipe up any spilled fuel oil from the
housing or fuel pump.
8. Reopen the fuel line shut-off valve by turning the red
knob counter-clockwise.
9. Before replacing the housing cover, check for leaks
around the pump cover during operation. To do this,
set up the Dragon outside and allow to run in HEAT
mode for several minutes. If the fuel pump cover does
not leak, proceed to step 9.
If the fuel pump cover leaks, turn off and unplug unit
before attempting to tighten or reseal the cover. If the
cover will not stop leaking, have the unit inspected at
a qualified service center.
10. Reattach the housing cover and guard plate.
Cleaning the Dragon
The heat exchanger and combustion chamber should
be cleaned at least once a year to remove soot
buildup.
The cleaning should be performed by a qualified
HVAC technician at a local service center. Contact
your local distributor or the Dri-Eaz Service
Department at 1-888-867-3235 for the location of a
service center near you.
To clean the Dragon housing, use a cleaner with a
degreasing agent similar to Simple Green
