11 CLEANING AND MAINTENANCE
This unit must be inspected and maintained by a qualified,
recognised and registered person at least once a year. As
a minimum, the inspection and maintenance must ensure
the unit works correctly and safely. It is advisable that the
unit be cleaned of dust and dirt regularly during the heating
season, and especially when the unit has not been used for
an extended period of time. This can be done with a soft
brush and vacuum cleaner, or a damp cloth and non-abrasive
detergent if necessary. Do not use aggressive or corrosive
substances to clean the unit.
The concentric flue system must be cleaned every 2 years.
Also check:
1 The seal of the gas combustion products and combustion
air supply circuit.
2 The seal of the pressure hatches at the top and bottom
of the fireplace, control of the gasket.
3 The operation of the pressure hatches; that they can open
and close freely.
4 Correct operation of the gas control block and ignition of
the burner.
5 The seal of the explosion hatch must be checked and/or
be replaced after it has been activated.
6 Clean the convection space once a year.
Service and repair
If this unit needs to be inspected and/or repaired, you can
completely remove the burner with base.
Removing the burner base and technical equipment.
Disassemble the glass pane with frame and possibly the
cover frame.
By loosening the cover frame, a little more space will be created.
Take the ceramic blocks out of the unit and then the grate.
Standing this up straight is easiest. The burner and burner
support on the left is then visible. There is a Parker screw here.
Partly loosen it, and then slide the burner to the left. The glow
material can therefore remain on the burner. We see the base
upon which the technical equipment is located.
There are Parker screws on the outer edge. These must be
unscrewed; the base plate can then be removed. Left side up
first, and then remove the entire thing with a slight twist up to
the left. The base is now loose. There is also a gas hose on the
technical equipment. Disconnect this hose, the base can then
be completely removed with the technical equipment. Replace
in reverse order.
Measuring nipples
If the plan is only to disassemble the burner, a square plate
under the gas pipe can be seen. Remove the four Parker
screws and release the plate. Look through the hole and you
can see a small, silver-coloured plate. This plate can be turned
counter clockwise. The measuring nipples are now visible.
The left nipple is for the supply pressure, and the right nipple
is the burner pressure. You can now insert a hose through the
convection chamber towards the measuring nipples and use a
set of combination pliers to slide the hose onto the measuring
nipple. The detached plate can then be replaced with the burner.
Turn the fireplace on to check the gas pressure. Then put
everything back in reverse order. The burner pressure can
only be adjusted if the fireplace is not yet installed. Remove
the front panel; this makes installation easier.
If the burner pressure is to be adjusted after installation,
this can be done by removing the burner and the base.
