MAINTENANCE
(ref. Parts List)
IMPORTANT
Before carrying out any adjustment or maintenance, ensure the heater is
switched OFF, disconnected from the mains supply, and has been given
adequate time to cool down, unless otherwise stated.
It is essential that the heater is correctly maintained and kept in top condition at all
times.
Those items requiring regular maintenance comprise,
1. Intake Air Filter (Item 2)
2. Output Air Filter (Item 5)
3. Fan (Item 20)
4. Fuel Nozzle (Item 26)
5. Ignition Electrodes (Item 23)
6. Fuel Filter (Integral part of item 27)
The Intake and Output Air Filters, are accessible by removing the Grille (by
removing the single hex socket centre screw), whereas accessibility to the
remaining items requires the removal of the top cover (by removing the six screws
at the centre joint).
Monthly
Intake Air Filter
Pull off the Intake Air Filter, which lies directly behind the Grille, and wash in a light
detergent. Thoroughly dry before re-installing.
In dusty environments it may be necessary to carry out this procedure weekly.
Never allow the filter to get blocked..
Ignition Electrodes
Having removed the heaters’
top cover, remove the single
screw retaining the electrode
holder. Withdraw the holder,
clean and adjust the gap
between the electrodes, to
4mm.
When re-installing the electrode holder, there must be a gap of 9mm between the
electrodes and the nozzle (see fig. 4). If this adjustment needs to be re-set, it is
preferable to remove the burner head complete, by removing the securing
screws around its’ edge, taking care not to damage the photocell. The electrodes
may then be adjusted to their correct clearance before replacing the Burner
Head.
