MAINTENANCE
It is essential that the heater is correctly maintained and kept in top condition at all times.
IMPORTANT
Before carrying out any adjustment or maintenance, ensure the heater is
switched OFF, disconnected from the mains and gas supply’s, and has been
given adequate time to cool down.
All models are similar, in that access to the working parts, is gained by removing
the rear panel, which is secured by 4 screws, (3 in the case of the Little Devil),
around its’ edge. Once removed, the panel complete with all components may
be lifted clear.
Monthly (When in constant use)
Ensure the electrode is clean, and the gap is no more than 5mm (see fig 4).
Check the condition of the gas hose, if there are any signs of deterioration, it
should be renewed, using only a CLARKE original spare part.
Ensure that all connections are clean and firm.
When necessary, clean the fan and inside of the heater thoroughly.
