For your safety

1 For your safety

GB142 condensing gas boilers are designed and

built according to the latest technological advances

and safety requirements.

The design is specifically focused on ease of use.

To ensure the safe, economical and environmen-

tally friendly use of the heating system we urge you

to read and observe the User's Instructions.

1.1 Designated use

The GB142 was designed for heating water for a

central heating system and for generating domestic

hot water. The boiler can be fitted with a modulating

outdoor reset control AM10 (scope of delivery),

a room controller RC35 (optional) or an On/Off

thermostat (accessory).

For your safety

INOTICE

Indicates special instructions on installation,

operation or maintenance that are important

but not related to personal injury or property

damage.

1.2 Safety instructions

Make sure to observe these safety instructions.

Failure to do so can result in property damage,

personal injury or loss of life.

– Installation, gas and flue connection,

commissioning, electrical connection and

maintenance activities must only be carried out

by a trained service provider.

– Certain work, e.g. on gas lines, may require a

professional license. Only carry out such work if

you are licensed to do so.

– Only use the boiler for its intended purpose and

only when it is in working order.

– Have a trained service provider check, clean

and service the heating system once a year.

Buderus recommends a contract for annual

service and maintenance.

– The condensate collection and disposal system

must be periodically cleaned by a trained

service technician.

– Have your trained service provider give you

detailed instructions about the operation of the

heating system.

– Carefully read these user's instructions.

– Immediately have all defects to the heating

system repaired.

– Ensure that air intake and outlet openings are

open and free from obstructions at all times.

– Do not store any flammable material or liquids in

the immediate vicinity of the boiler.

http://www.buderus.net 7

For your safety

– Never use chlorinated detergents or

halogenated hydrocarbons (e.g. in spraycans,

solvents and detergents, paints, adhesives) in

the room where the boiler is installed.

– When Calcium Chloride is present in concrete

floors (when poured in winter) it is necessary to

seal the floor with a suitable paint.

– Do not allow too much dust to collect on the

device.

– Do not use the boiler if any part has been under

water. Immediately call a trained service

technician to inspect the boiler and to replace

any part of the control system and any gas

control which has been under water.

– Should overheating occur or the gas supply fail

to shut off, do not turn off or disconnect the

electrical supply to the pump. Instead, shut off

the gas supply at a location external to the

boiler.

– The venting system must be inspected annually.

Replace any parts which show deterioration

from corrosion or any other sources.

– This boiler does not have a pilot. It has an

ignition device which automatically lights the

burner.

– Check for smell of gas around the boiler area.

Be sure to smell next to the floor because

propane gas is heavier than air and will settle on

the floor.

– Use only your hand to turn the gas control knob

(fig. 3 on page 15). Never use tools. If the knob

will not turn by hand, don't try to repair it, call a

trained service technician. Force or attempted

repair may result in a fire or an explosion.
