Safety instructions

Observe these instructions for your safety.

The burner and control must be correctly installed and adjusted to 
ensure safe and economical operation of the gas boiler.

Read this installation and maintenance manual carefully and note the 
details on the boiler nameplate before placing the boiler in operation.

Risk of fatal injury from explosion of flammable gases

If you smell gas there is a danger of explosion.
▶ Never work on gas lines unless you are licensed for this type of work.
▶ Make sure that a qualified company installs the boiler, connects gas 

and ventplaces the boiler in operation, connects the electrical power, 
and maintains and repairs the boiler. 

▶ No open flame! No smoking! Do not use lighters
▶ Prevent spark formation.  Do not operate electrical switches, 

including telephones, plugs or door bells.

C

lose main gas valve.

▶ Open doors and windows.
▶ Warn other occupants of the building, but do not use door bells.

C

all gas company from outside the building.

▶ If gas can be heard escaping, leave the building immediately, prevent 

other people from entering, notify police and fire departments from 
outside the building.

Risk to life from electrical shock.

▶ Disconnect the power supply to the boiler heating system before 

conducting any work on it, e.g. turn off the heating system emergency 
switch outside the boiler room.

▶ It is not sufficient just to turn off the control.
▶ Do not carry out electrical work unless you are qualified for this type 

of work.

▶ Before disconnect electrical power completely and pad lock to 

prevent accidental reconnection.

▶ Observe the local installation regulations.

Risk of fatal injury from flue gas poisoning

Insufficient ventilation or combustion air availability may cause 
dangerous flue gas leaks or formation.
▶ Make sure that inlets and outlets are not reduced in size or closed.
▶ If faults are not corrected immediately, the boiler must not be 

operated until all faults have been corrected.

▶ Inform the system operator and/or owner of the fault and the danger 

in writing.Elektroanschluss nur durch eine Elektrofachkraft ausführen 
lassen.

When working on the flue gas venting equipment or vent damper leakage 
of flue gases may endanger the lives of people.

C

arefully observe proper operation of the vent damper. Do not start 

up the boiler unless the vent damper is operating properly.

▶ Use only original parts when replacing parts.
▶ When replacing the vent damper, install the new one in the specified 

position.

Risk to life by poisoning by spillage of flue gases

▶ If the blocked vent switch trips frequently the fault must be corrected 

and proper operation of the blocked vent switch test must be 
conducted.

Risk to life by poisoning by leakage of flue gases

▶ Make sure that the boiler is not equipped with a thermally controlled 

flue gas vent damper after the open draft hood.

Risk of fatal injury from neglecting your own safety in case of 
emergency, such as with a fire

▶ Never put yourself at risk. Your own safety must always take priority.

Fire danger due to flammable materials or liquids

▶ Make sure that there are no flammable materials or liquids in the 

immediate vicinity of the boiler.

▶ Maintain a minimum distance of 15 inches from the boiler.

Installation and maintenance

▶ Observe all current standards and guidelines applicable to the 

installation and operation of the boiler heating system as applicable in 
your state or local jurisdiction.

C

lean and service the boiler system once a year. 

C

heck that the 

complete heating system operates correctly.

▶ Immediately correct all faults to prevent system damage.
▶ Only use original Buderus spare parts. Losses caused by the use of 

parts not supplied by Buderus are excluded from the Buderus 
warranty.

Warnings in this document are identified by a warning 
triangle printed against a grey background.
Keywords at the start of a warning indicate the type and 
seriousness of the ensuing risk if measures to prevent
