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 Benson Environmental Ltd.
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.
