The condensate trap must
always be filled to the edge
with water, before replacing
to the unit.
Install the new insulation:
- Put two dots of glue silicone, temperature-resistant (Loctite 5366 or
Ottoseal S17), according to the location indicated.
- Make sure that the burner is in proper condition, remove any possible
insulation residues on the burner.
- Put a plastic protection skirt around the burner to protect the insulation
from the burner.
- Engage the insulation carefully and place it in contact with the two dots of
silicone glue.
- Remove the plastic protection skirt.
- Check the condition of the electrode, if necessary, replace it.
- Reinstall electrodes.
- Mount the burner door correctly back onto the heat exchanger, taking in
account the correct torque values, see chapter 19.2.1.
Fan
When the fan blades are polluted and dirty, carefully clean the blades with a soft brush. Notice: do not use too
much force on the blades or else the fan might be out of balance and run irregularly, causing noises and fan
failures. Check the fan also for any water damages. In doubt always replace the fan of the boiler.
Condensate Trap
Disassemble the condensate trap and clean every part of it. Check the condensate trap connection of the heat
exchanger for any blocking or pollution and clean it (if necessary). Check the functioning of the condensate trap
by pouring clean tap water in the boiler combustion chamber (when burner door is removed). This water will exit
the heat exchanger by the condensate trap. Notice: don’t wet the rear wall insulation.
When mounting the bottom part of the condensate trap, before commissioning the boiler
and/or after maintenance, the condensate trap must
ALWAYS
be completely filled with
water.
This is a safety measure: the water in the condensate trap keeps the flue gases
from leaking out of the heat exchanger via the condensate drain.
Heat exchanger and boiler combustion chamber
After the removal of the complete burner unit check if there is any debris and dirt in the heat exchanger. The coils
of the heat exchanger can be cleaned by using a
non-metallic
brush. After this the dirt and dust can be removed
with a vacuum cleaner and by flushing the boiler combustion chamber with water. Never expose the refractory
insulation in the back of the combustion chamber to water or get it wet. Don’t forget afterwards to clean the
condensate trap once again.
