There is an inspection glass on the air box on the fan
side. Check the air box for dirt using a lamp. If the air
box is dirty, it must be dismantled and blown clean.
If the air box is dirty, the following components must

15.4.5 Cleaning the heat exchanger
Release the retaining nuts from heat exchanger cover
plate, remove plate, be careful not to damage the gas-
ket, store safely.
Heat exchanger can be washed with clean water, if
badly contaminated, clean with a small stiff bristle "bot-
tle type" brush or use the special cleaning tool (supplied
optional). Care should be taken when using water in the
confined space of the boiler casing to avoid contaminat-
ing the electrical controls. Compressed air can also be
used but care should be taken to ensure disturbed dust
etc does not contaminate the rest of boiler and controls.
Replace the heat exchanger front plate after the clean-
ing and tighten the retaining nuts.
