Maintenance

Safety instructions

The following symbols are used in conjunction with these

important instructions concerning personal safety as well

as operational reliability.

„Safety instructions“ are instructions with

which you must comply exactly, to prevent

injury and material losses.

Danger through ‚live‘ electrical components.

Please note: Switch OFF the ON/OFF switch

before removing the casing.

Never touch electrical components or contacts

when the ON/OFF switch is in the ON position.

This brings a risk of electrocution, which may

result in injury or death.

The main supply terminals are ‚live‘ even when

the ON/OFF switch is in the OFF position.

This indicates technical instructions which you

must observe to prevent material losses and

boiler malfunctions.

Danger from electric power

Fig.: Ignition transformer, high voltage ignition electrode,

combustion chamber

Danger through ‚live‘ electrical components; danger through

hot components

General notes

Maintenance work must only be carried out by a

qualified heating contractor.

Regular maintenance and the exclusive use of ori-

ginal Wolf spare parts are necessary preconditions

for trouble-free operation and a long service life.

We therefore recommend you arrange a mainte-

nance contract with a local heating contractor.

Risk of electrical shock, risk of poisoning and explosion from

escaping gas

Fig.: Gas connection: Escaping gas may cause poisoning or

the risk of explosion
