Boiler inspection and maintenance

15.1

Why is regular maintenance important?

Heating systems require regular maintenance for the following reasons:
• to maintain high efficiency operation and to operate the heating
system economically (low fuel consumption),
• to sustain safe operation,
• to maintain combustion at an environmentally responsible level.
• to ensure trouble-free operation and long life.
All maintenance work must be carried out by a qualified boiler
technician. When replacing components use only parts approved by
Buderus. Maintenance is required once a year. Record the results of the
inspection in the protocol on page 25.
Spare parts can be ordered from the spare parts catalog.
15.2 Testing the flue system, including combustion air, air
inlets and Ventilation openings
Check the venting system, including the combustion air, inlet and outlet
openings. All faults must be repaired immediately. Make sure that the
combustion air feed and the inlets and outlets are not blocked at any
point.
15.3

Inspection of the boiler and burner

▶ Visually check the boiler and burner for external dirt.
▶ If dirt is found, clean boiler and burner.
15.4

Preparing boiler for cleaning

▶ Take the boiler out of operation ( chapter 14).
WARNING: Risk to life from electric shock.
▶ Before opening a unit: disconnect electrical power
and lock to prevent accidental reactivation.
▶ Open and remove front door of boiler ( figure 19, page 15).
WARNING: Risk to life from explosion of flammable
gases.
▶ Never work on gas lines unless you are licensed for
this type of work
▶ Turn gas valve ON/OFF knob clockwise to OFF position. Do not use
force.
WARNING: Risk to life from explosion of flammable
gases.
▶ Wait five (5) minutes until all gas residues have
dissipated. Check whether there is any smell of gas,
including at floor level. If there is a gas odor, shut of
main gas valve immediately. Turn off power to the
heating system and call your customer service
technician or gas company.
