regular servicing carried out by competent

5.0 Servicing
Warning
Servicing must be carried out on a regular
basis, the maximum interval between
services being 1 year. It is a requirement that
only suitably qualified and competent
persons are allowed to undertake servicing.
Before any maintenance or servicing work is
carried out the heater must be shut down
and allowed to cool, and have the gas and
electric supplies to it turned off at the gas
cock and isolator respectively.
Caution
Certain component parts are factory sealed
and are designed so as to be tamper proof.
Usually such items do not require servicing,
and therefore should not be tampered with.
Failure to comply with this can invalidate any
warranty, and can also lead to premature
failure.
The following parts fall within this category:
room thermostat, time clock, frost thermostat,
sequential controller, and fan and motor.
Additionally, the fan and limit stat has been
factory set, and must not be re-set without
formal consent from the manufacturer.
Reference should be made to the separate
information covering the operational details
of the burner and timer.
Only approved spare/replacement parts
can be fitted, failure to comply with this
can compromise the safe and efficient
running of the heater, and can also
invalidate any warranty claim.

5.2 Servicing Procedure - Major
Component Parts
Flue
A visual inspection should be carried out to
ensure that the flue remains adequately
supported, both internally as well as
externally, and that the various joints are
effectively sealed.
Inspection covers, where fitted, should be
removed and the flue checked to see
whether cleaning is required If inspection
covers are not fitted the flue gas exit duct
and flue spigot will provide not only an
indication of the cleanliness of the flue, but
will also enable access for cleaning. The
presence of the flue terminal should be
checked. If a condensate trap and drain
facility is fitted this should be checked to
ensure that it continues to function correctly,
and the drainage of condensates is not
impaired.
Main Fan Motor
Remove access panel, dust and other
foreign matter should be cleaned by blowing
over with compressed air and through the
use of a soft bristle brush and cloth. Solvent
