later date, e.g. kitchen exhaust fans, clothes dryers, and air conditioning units
with vent to the outside.
▶ Never operate the appliance if the supply of combustion air is insufficient.
Danger of explosion of flammable gases.
▶ Only employ a trained and certified contractor to carry out work on the gas train.
Risk of scalding
▶ 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.
▶ 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.
▶ Ensure that children never operate this appliance unsupervised or play with it.

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).
