WARNING
20 INSPECTION, MAINTENANCE AND SERVICE.
General
For a good, safe and long-time operation of the water heater and to maintain warranty it is mandatory to carry out
inspection, maintenance and service on the water heater at least once a year.
Inspection, maintenance and service of the water heater should also be carried out on the next occasion
•
When a number of similar error codes and/or lockouts appear.
•
At least every twelve months maintenance must be done to ensure safe and efficient operation.
Damage caused by the lack of maintenance will not be covered under warranty
Service intervals
The normal service frequency for the water heater is once a year. Every year the water heater should be cleaned
and checked, according to the maintenance procedures. If there is doubt whether the water heater is operating
with the correct water and/or combustion air quality, it is advised that a first check is already executed 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 should 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 should also be replaced. Only use the insulation disk that is supplied by the boiler manufacturer.
The same procedure must be applied on the insulation and gaskets fitted on the burner door.
Refractory Ceramic Fibers (RFC)
Personal Protective Equipment Required - Read the following warnings and handling instructions carefully be-
fore 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 should 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.
Potential Carcinogen - Use of Refractory Ceramic Fibers in high temperature applications (above 1805 °F) can
result in the formation of Crystalline Silica (cristobalite), a respirable silica dust. Repeated airborne exposure to
crystalline silica dust may result in chronic lung infections, acute respiratory illness, or death. Crystalline silica is
listed as a (potential) occupational carcinogen by the following regulatory organizations:
International Agency for
Research on Cancer (IARC), Canadian Centre for Occupational Health and Safety (CCOHS), Occupational Safety
and Health Administration (OSHA), and National Institute for Occupational Safety and Health (NIOSH). Failure to
comply with handling instructions in the table in § 19.2
may result in serious injury or death.
Crystalline Silica - Certain components in the combustion chamber may contain this potential carcinogen. Read
warnings and handling instructions pertaining to Refractory Ceramic Fibers before commencing service work in
the combustion chamber. Take all necessary precautions and use recommended personal protective equipment
as required see the table in § 19.2 Installation and service must be performed by a qualified installer, service
agency or the gas supplier who must read and follow the Installation, Operation, and Service Manual before per-
forming any work on this water heater. Improper installation, adjustment, alteration, service or maintenance can
cause property damage, serious injury (exposure to hazardous materials) or death.
Label all wires prior to disconnection when servicing controls. Wiring errors can cause im-
proper and dangerous operation. “Verify proper operation after operation servicing.”
INSPECTION, MAINTENANCE AND SERVICE MUST BE EXECUTED FOR A SAFE AND
EFFICIENT OPERATION OF THE WATER HEATER.
