4. Inspect the surfaces of the firebox for any signs of
corrosion. Use a wire brush to clean if needed.
4. Chimney Tee
1. Remove the chimney inspection cover. Clean the
chimney outlet and chimney of excessive ash or
deposits.
NOTE: The chimney inspection cover must fit
tightly. Check and clean if necessary the groove
for the cover to prevent air from leaking out.
Leaking air caused by an improperly fitting cover
can cause corrosion.
2. Use a small mirror to check that the chimney is
clear.
3. Install the chimney inspection cover on the chimney
tee.
5. Chimney Transition Box
1. Remove the top rear panel and the access cover to
the heat exchanger. If there is any ash in the area
behind the access cover, remove it.

6. Heat Exchangers
NOTE: Cleaning the heat exchangers when the
water temperature is about 150˚F (65.5˚C) will
help in removing deposits.
1. Insert one chain attached to the heat exchanger
scraper into the heat exchanger chamber; then insert
the heat exchanger scraper and drop it down the
chamber while holding on to the second chain. Once
the heat exchanger scraper drops to the bottom of
the heat exchanger, drop the second chain down the
heat exchanger. Repeat this procedure for all eight
heat exchanger chambers.

2. Inspect all heat exchanger chambers to make sure
that the fly ash or any deposits were removed.
Repeat step 1 if necessary.
NOTE: Using a light and mirror will aid with the
inspection of the chambers.
3. Replace the access covers, insulation and top rear
panels.
7. Reaction Chamber
1. Lift and slide the charge tube toward the front of the
outdoor furnace to remove; then inspect the mixing
channel to see the area is not plugged.
2. Install the charge tube.
3. Using a hoe and small shovel, remove all of the
ash and deposits from the Reaction Chamber being
careful not to damage the temperature sensor (see
Fig. 61).
CAUTION
Take care not to damage the temperature sensor
when removing ash.
4. Install the refactory removed earlier. Close the
Reaction Chamber door and install the wing nut;
then close the rear access door.
