These appliances should be serviced annually by a competent person to ensure safe and efficient
operation. In exceptionally dusty or polluted conditions more frequentservicing may be required.
The manufacturer offers a maintenance service. Details available on request.
Isolate gas and electricity supplies before commencing any work.
Tools Required
The following tools and equipment are
advisable to complete the tasks laid out in this
manual.
Suitable alternative tools may
be used.
Burner assembly
The major components of the burner assembly
can be accessed by removing the two retaining
nuts located on the door so that door can easily
be opened (see figure 29 & 30 on page 17).
In case of insufficient space to reach the
components, remove the cover at the bottom.
Before removing the 4 retaining nuts at the
bottom of the cover, make sure that electrical
contacts of both lamps and switch are
disconnected. We refer to figures 31 & 32 on
page 18. Section ‘Parts Replacment’ explains how
to remove the major components.
Manifold / injectors
Remove the manifold complete with injectors
as described in section ‘Parts Replacement’. The
manifold/injectors should be examined for signs
of debris and cleaned if necessary by blowing
compressed air in the reverse direction to flow.
Individual injectors can be replaced if necessary.
6,2,2 Burners
Access to the burners is achieved by first
detaching and slipping aside the panel of the
control unit (see page 16). The burners can now
be examined and cleaned using a soft brush, or
by blowing compressed air in the reverse direction
to flow. Individual burners can be replaced if
necessary by removing the clamping plate (see
page 19). The complete burner rack can also be
removed following the instructions described in
section 19.
Spark electrode
Remove the spark electrode as described in
section 8 and examine. If it is in good order check
the electrode gap, this should be 3.18mm ±
0.5mm. Adjust the gap if necessary by carefully
bending the earth rod, then re-checking the
measurement.
Flame probe
Remove the flame probe as described in section 8
and examine for signs of erosion.
The probe should be cleaned if necessary
using a fine grade emery paper.
