Product Description

Danger of electric shock when the boiler is open.
Before opening the boiler:
▶ Disconnect the heating system from the electrical power supply via
the ON/OFF switch or the appropriate building fuse. It is not
sufficient just to switch off the controller. Power to the controller
must be disconnected.
▶ Take measures to ensure that the heating system cannot be
accidentally reactivated.
▶ Electrical work may be carried out only by qualified and certified
electricians.
Danger due to short-circuits
To prevent short circuits:
▶ only genuine Buderus wiring replacement parts.
▶ Do not attempt to operate an appliance if any part of it has been
under water.
▶ Replace any appliance that has been under water.
Risk of system damage due to contaminated combustion air supply
▶ Keep the combustion air free of corrosive substances, e.g.
halogenated hydrocarbons from painting operations or beauty
salons.
▶ Keep combustion air free from dust and lint (e. g. from nearby
laundry or agricultural operations).
▶ If clean room air is not available, fresh outdoor combustion air must
be provided.
Risk of system damage in the event of improper operation
▶ Use the boiler only for its intended purpose.
▶ Operate the boiler only if it has been installed and maintained per the
instructions provided in the Installation Manual.
▶ Do not attempt to operate an appliance if any part of it is not in
working order or is damaged.
▶ Use only original spare parts. The use of parts not supplied by the
manufacturer may cause damage to the boiler, other property and
personal injury. Also, boiler damage caused by the use of
unauthorized parts is not covered by the warranty.
▶ With sealed combustion appliances: do not cover or reduce the size
of air inlet and ventilation openings in doors, windows and walls.
▶ If draft-proof windows are installed, ensure an adequate supply of
combustion air.
Notice regarding regulations and legal requirements
▶ The installation must comply with all applicable national, state, and
local codes, rules, and regulations.
▶ The operator is responsible for the operational safety and regulatory
compliance of the heating system.
▶ In the Commonwealth of Massachusetts, the appliance must be
installed by a licensed plumber or gas fitter.
Instructing the owner/operator
▶ The installer must instruct the owner and operator on the
functionality of the components and the proper operation of the
boiler and the heating system.
▶ Upon completion of the installation, these instructions should be
handed to the owner and operator of the appliance.
▶ Inform the owner/operator that they must never carry out any
modifications or repairs.
