appliances installed at a later date, e.g. kitchen exhaust fans, clothes dryers, and air conditioning units with vent to the outside.
B Never operate the appliance if the supply of combustion air is
insufficient.
Guideline to symbols and safety instructions | 9
Danger of explosion of flammable gases.
B Only employ a trained and certified contractor to carry out
work on the gas train.
Risk of scalding
B If running at DHW temperatures above 104 °F (40 °C) ask a
trained and certified heating contractor to install a tempering valve to prevent scalding.
B When the thermal disinfection function is enabled, DHW
temperatures above 140 °F (60 °C) can occur.
Risk of damage due to operator error
Operator errors can result in personal injury and damage to property.
B Ensure that children never operate this appliance unsupervised
or play with it.
B Ensure that only people who know to operate this appliance
correctly have access to it.

10 | Guideline to symbols and safety instructions
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 demand­dependent 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.
