Safety information
2.3 Risk of suffocation/poisoning
Devices with insufficient combustion air supply or flue gas
removal may cause flue gas to leak into the installation

life-threatening poisoning.
- Switch OFF the appliance if you smell flue gas
- Open windows and doors
- Notify an approved contractor
2.4 Risk from water-polluting materials
Oil condensing boilers include oil-bearing parts. This is a
risk to health from drinking water contaminated with oil.
- L ock the oil supply to oil-bearing parts before starting
any work.
- P erform a seal inspection on oil-bearing parts after work
has finished
2.5 Risk of scalding

allow the appliance to cool to below 40 °C, shut off all
valves and, if necessary, drain the appliance.
2.6 Risk of burns
Boiler components may be extremely hot.
Hot components can cause burns.
Before working on the opened up appliance, allow it to cool
below 40 °C or wear suitable gloves.
2.7 Danger from pressurised water
Boilers are subject to high water pressure.
Water pressure can cause severe injuries.
Before working on parts which are in contact with water,
allow the appliance to cool to below 40 °C, shut off all
valves and, if necessary, drain the appliance.
Note: S ensors can be in contact with water and therefore
