7.3.18 Heat Exchanger Inspection and Cleaning
- With the heat exchanger door in place and the burner tube removed
or with the door entirely removed, use a torch to examine the
inside of the heat exchanger.
Inspection
with door
in place
- The heat exchanger should be bright and free from deposits or major
patches of discolouration.
- If necessary deposits can be removed (see section 7.3.15 for door removal)
with a nylon brush. Loose deposits can either be vacuumed out or water
used to flush the deposits into the condense drain.
- For stubborn deposits apply white vinegar to the coils, using a hand sprayer
and leave for 3 minutes. Remove deposits using a nylon brush and rinse
with plenty of clean water (repeat if necessary).
- Inspect condition of door seals and replace if there is any sign of wear or
damage.
Do not use chemical treatments to clean out deposits from the heat exchanger. Use only
clean water or white vinegar as instructed above.
When using water to flush through the heat exchanger, ensure that water exposure to
the insulation material at the end of the heat exchanger is minimised to prevent
damage to this insulation.
