Inspection and maintenance
The operator is responsible for safety and environmental
compliance of the heating system.
Sign a maintenance and inspection contract with a trained and
certified contractor, covering an annual inspection and demand-
dependent maintenance. This guarantees high efficiency and
environmentally sound combustion.
Explosive and easily combustible materials
Never use or store easily combustible materials (paper, thinners,
paints, etc.) near the appliance.
Combustion air / room air
To prevent corrosion, keep the supply of combustion air /
room air free of corrosive substances (e.g. halogenated
hydrocarbons that contain chlorine or fluorine compounds).
Overheating of the appliance
Should overheating occur or the gas supply fail to shut off, do not
turn off or disconnect the electrical supply to the pump. Instead,
shut off the gas supply at a location outside of the appliance.
In case of water damage
Do not use this boiler if any part has been under water.
Immediately call a trained and certified service technician to
inspect the boiler and to replace any part of the control system
and any gas control which has been under water.
