Table 2 Requirements of heating system water
2.5
The correct fuel
To ensure it operates properly, the heating system requires fuel of the
correct type and grade.
NOTICE: Risk of system damage from use of incorrect
fuel.
▶ Only use the fuel specified. The correct fuel is entered
in Tab. 3 by the heating contractor.
Consult your system installer if you intend on changing
the fuel for your system.
NOTICE: Risk due to oil leaks
▶ When using oil as the fuel, national regulations hold
the operator responsible for immediately calling a
specialist contractor to remedy oil leaks the moment
they are discovered.
2.6
Combustion Air Quality
▶ Keep the supply of combustion air free of corrosive substances (e.g.
halogenated hydrocarbons that contain chlorine or fluorine
compounds).
This will help prevent corrosion.
▶ Never use or store chlorinated cleaning agents or halogenated
hydrocarbons (as contained in spray cans, solvents or cleaning
agents, paints and adhesives, for example) in the boiler room.
▶ Keep the combustion air supply free of dust.
▶ If building work is taking place in the installation room and creating a
lot of dust, shut the boiler down.
▶ A burner contaminated during building work must be cleaned before
commissioning.
