Burner with face insulation removed
6. The burner mesh can be cleaned by either
placing it under clean running water or
by immersing it in a container full of clean
water. The burner should be allowed to dry
naturally or be blown dry using compressed
air (drying air should not exceed 1.5 bar).
7. Replace the burner gasket if necessary.
8. Refit in reverse order.
9. Follow start up and commissioning
procedure.
Burner chamber / tube insulation
check and replacement
1. The insulation material is a mixture
containing Refractory Ceramic Fibres (RCF)
/ Alumino-Silicate Wools (ASW). Do not
handle until all safety instructions have
been read.
2. Wear appropriate PPE such as gloves,
protective clothing, eye protection,
and respiratory protection. Follow all
local regulations and industrial hygiene
standards.
3. Handle insulation with care to minimise
airborne dust.
4. Dispose of waste in accordance with local
regulations, such as a landfill licensed for
this purpose.
5. Unless wetted, such waste may be dusty
and should be properly sealed in containers
for disposal.
6. The Material Safety Data Sheet is available
from the appliance manufacturer.
7. With the burner removed the integrity
of the combustion chamber and tube
insulation can be verified. It is normal for
small superficial cracks to be present in the
surface of the insulation.
8. Remove any debris from inside the burner
chamber. A vacuum with a minimum of M
Class dust extraction rating can be used.
Do not use compressed air.
9. Check the integrity of the insulation. Use
a torch to inspect the insulation sleeves
fitted into each tube. Broken tube inserts
or the presence of deep cracks or warping
indicate that the insulation needs to be
replaced.
10. To remove the chamber insulation the
burner probes must first be removed. See
cleaning and replacement of burner probes
for procedure.
11. With the burner probes removed the
insulation block can be pulled out from the
chamber. This will reveal two additional
thin strips of insulation material. The first
is located at the front of the chamber
where the tubes are secured. The second
is located on the lower right side of the
chamber where the probes are normally
located. It is recommended that both of
these thin insulation strips are replaced
whenever the cast insulation block is
removed. Ensure the lower right insulation
strip has the preformed holes lined up with
the probe holes in the side of the chamber.
