18 INSPECTION, MAINTENANCE AND SERVICE
General
For a good, safe and long-lasting operation of the boiler and to maintain warranty it is mandatory to carry out
inspection, maintenance and service on the boiler at least once a year.
Maintenance and inspection of the boiler must be carried out in the following situations:
•
When a number of similar error codes and/or lockouts appear.
•
At least once every 12 months to ensure safe and efficient operation.
Damage caused by lack of maintenance will not be covered under warranty.
Service intervals
The normal service frequency for the boiler is once a year. Every year the boiler must be cleaned and checked,
according to the maintenance procedures. If there is doubt whether the boiler is operating with the correct water
and/or combustion air quality, it is advised that a first check is executed already after six months. This check serves
to determine the frequency of the future services. The maximum interval between two services is one year.
Safety instructions Crystalline Silica
Refractory Insulation
The refractory insulation of the heat exchanger (located on the rear wall inside the heat exchanger and burner
door) must be inspected. If this insulation disk shows any signs of (water) damage or degradation it must be
exchanged. Also check if there are any indications in the burner room of a high condensate level (caused by a
blocked condensate trap) that might have wetted the rear wall insulation. When this has happened, the rear wall
insulation must also be replaced.
Only use the insulation disk that is supplied by the boiler manufacturer.
The same procedure must be applied to the insulation and gaskets fitted on the burner door.
Personal Protective Equipment Required - Read the following warnings and handling instructions carefully
before commencing any service work in the combustion chamber. The insulating material on the inside of the
burner plate and the rear combustion chamber wall contain
Refractory Ceramic Fibers and must never be handled
without personal protective equipment. When disturbed as a result of servicing, these substances become airborne
and, if inhaled, may be hazardous to your health.
