Part 12 - Annual maintenance and inspection
Warning
This appliance must be inspected:
At the beginning of every heating season, and at least every 12 months, by a Qualified
Technician. When the appliance generates a series of similar faults.
Annual Inspection Checklist
Ask the user if there are any problems with the CH appliance or any other remarks. The remarks
or complaints of the customer about the operation of the CH boiler may indicate hidden defects
and problems.
Check the water pressure of the system. It must be between 1 and 1.5 bar (14.5 and 22 Psi). Bring the
pressure of the installation between 1 and 1.5 bar (14.5 and 22 Psi), find any leaks in the installation
and have this repaired by a registered installer or service centre if necessary.
Remove the housing from the appliance and check all pipes and connections for traces of water and/or
water leakage. Any leaks must be repaired. Check the top side of the housing and/or the top side of the
appliance for water leakage or traces of water from the air supply pipe or the vent. Find the cause
when water is leaking from the air supply pipe. This may be found in the roof surface.
Open the condensate trap and remove any dirt present. Flush if the condensed water coming from the
condensate trap is heavily contaminated. If the burner has already been removed, let water flow into
the heat exchanger through a filling hose. This will reach the condensate trap.
Let the appliance burn at maximum power and measure the load and the CO2 percentage. If
necessary, adjust the gas setting for the maximum load at the gas valve.
Let the appliance burn at minimum power and measure the load and the CO2 percentage. If
necessary, adjust the gas setting for the minimum load at the gas valve.
Listen to the sound of the CH pump and the fan. If the CH pump or fan makes noise, it is
recommended to replace the part preventatively.
In case of a too small tap water quantity (Cxxx types), check the water quantity limiter for dirt. If it
is clean, descale or replace the heat exchanger for the tap water.
Check if the supply to the CH installation does not get warm when heating the tap water. If the
temperature of the supply water increases while tapping, this means that the 3-way valve on the
inside has been contaminated and needs cleaning or replacement.
