Safety considerations

If you smell gas
▶ Turn off the gas cock ( page 40).
▶ Open windows and doors
▶ Do not operate electrical switches , including telephones, plugs or
doorbells.
▶ Extinguish all open flames. Do not smoke. Do not use lighters.
▶ Warn all occupants of the building, but do not ring doorbells.
▶ If you can actually hear gas escaping, leave the building immediately.
Prevent others from entering and notify the police and fire
department from outside the building.
▶ From outside the building, call gas supply company and licensed
heating contractor.
If you smell flue gas
▶ Switch off the boiler ( page 40).
▶ Open windows and doors
▶ Inform an authorized heating contractor.
Danger of poisoning. Insufficient ventilation may cause dangerous
flue gas leaks.
▶ Never close off or reduce the size of air intake and outlet openings.
▶ Never operate the boiler unless faults are rectified immediately.
▶ Inform the system user in writing of the problem and associated risk.

Danger of explosion of flammable gases.
▶ Any work on components that carry gas or oil may be carried out only
by a certified heating contractor.
Dangers posed by explosive and easily combustible materials
▶ Never use or store easily flammable materials (paper, curtains,
clothing, thinners, paints etc.) near the boiler.
▶ Maintain a clearance of 16 inches from the boiler.
Combustion air
▶ Keep the combustion air free of corrosive substances (e. g.
halogenated hydrocarbons that contain chlorine or fluorine
compounds). In that way, corrosion will be prevented.
Danger of escaping flue gases
▶ Make sure that the vent pipes and gaskets are not damaged.
▶ Use high temperature silicon as sealing compound.
▶ The boiler must not be fitted with a barometric damper or a thermally
controlled vent damper downstream of the flue connector.
▶ Connect only one boiler to each venting system or chimney.
▶ Connection of another boiler may cause serious injury or death.
▶ The flue system pipes must not feed into another air extraction duct.
▶ Do not route the flue system piping through or inside another air
extraction duct, for example where there is a masonry or
prefabricated chimney flue.
Danger of electric shock when the boiler is open.
▶ Before opening the boiler: Disconnect the heating system from the
electrical power supply by means of the emergency shutoff switch or
the appropriate circuit breaker on the main electrical panel.
▶ It is not sufficient just to switch off the controller.
▶ Take measures to ensure that the heating system cannot be
accidentally reactivated.
Danger due to short-circuits
To prevent short-circuits, use:
▶ only genuine Buderus wiring replacement parts.
