5. Remove the combustion intake assembly. See Fig.
36. The combustion intake assembly is held into place
with two swing latches. See Fig. 37. Swing each latch
until it hangs down away from the retainer stud. Now
the assembly can be taken out by tilting the right side
outward first through the lower door opening.
6. The units interior is now ready to clean. Use the
scraper provided to clean the heat exchanger surfaces.
A wire brush or short bristled brush is an excellent
cleaning tool. Clean the fan blade and combustion blower
fan housing. NOTE: Be careful not to bend the fan blade
while cleaning. A bent blade will throw the fan blade out
of balance. See Fig. 38.
7. With the blower housing open, there is easy access to
the flue pipe exiting the rear of the unit. See Fig. 38.
Vacuum the flue pipe as far into the pipe as possible.
NOTE: Be careful while cleaning the flue pipe not to
bend the ESP probe. The ESP probe is approximately
8" in the tube and is visible when looking into the tube.
