Safety instructions

If you smell gas
▶ Turn off the gas cock ( page 40).
▶ Open doors and windows.
▶ Do not operate any electrical switches or equipment such as
telephones, power plugs and 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 your gas supply utility and approved
contractor.
If you smell flue gas
▶ Switch "off" the boiler ( page 40).
▶ Open doors and windows.
▶ 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.
▶ The boiler must not be operated until the obstruction has been
removed.
▶ Inform the system user in writing of the problem and associated
danger.
Danger of explosion of flammable gases.
▶ Any work on components that carry gas or oil may only be carried out
by a certified heating contractor.
Dangers posed by explosive and easily combustible materials
▶ Do not use or store easily-combustible materials (paper, lace
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). This will help prevent corrosion.
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 flue flap downstream of the flue socket.
▶ Connect only one boiler to each flue system or chimney flue.
▶ 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 from electric current when the boiler is open
▶ Before opening the boiler: Disconnect the heating system from the
electrical power supply by means of the emergency stop switch or the
relevant circuit breaker on the main fuse board.
▶ It is not sufficient just to switch off the control unit.
▶ Take measures to ensure that the heating system cannot be switched
on again unintentionally.
