should be informed about the situation. Combustible objects should be
moved away from the chimney.
Warning from experts:
Do not attempt to put out the fire with water while
waiting. The temperatures in a chimney fire can reach up to 1300 °C. The
extinguishing water will immediately turn to steam. A 10 litre bucket of
water results in 17 m
3
of steam. The enormous pressure that results can
break the chimney apart.
Once the chimney fire has burnt itself out, the chimney must be examined
by a specialist for cracks or leakages and, if required, repaired accordingly.
6.4 MAINTENANCE
The door seal must be checked on a regular basis. If necessary, this seal is
to be replaced (due to wear, breakage etc.).
The firebox lining must be checked at regular intervals. It consists of natural
products that are subject to expansion and contraction during every heating
process. Cracks can occur as a result. As long as the firebox lining retains
its position in the fireplace and doesn’t break, it remains fully functional.
A yearly service of the stove carried out by a specialist is indispensible to
ensure fault-free functionality (where possible, before the heating season)!
The fireplace may not be modified!
Only original replacement parts that have been approved by the manufac-
turer may be used! Please contact your specialist dealer should you require
any parts!
6.4.1. MAINTENANCE OF THE WATER HEAT
EXCHANGER IN THE ambiente a4 H

O
Carrying out maintenance on the ambiente a4 H
2
O is essential. The ambiente
a4 H
2
O can only achieve its full effectiveness when it is regularly and prop-
erly maintained. A technical heating inspection of all safety devices (thermal
discharge safety device, etc.) is required
each year
before the heating
season. This inspection may only be carried out by a specialist company.
We recommend that you agree a
service contract
with your specialist
company. This ensures that the
yearly safety inspections
will be reliably
carried out
before
the heating season. All yearly safety inspections are to
be documented!
6.4.2 BLEEDING AIR OUT OF THE WATER HEAT

The bleeding process is carried out in the area of the heating connections
in the lower compartment. The bleeding vent is opened using the bleeding
key. A suitable collection container or a large cloth should be kept ready
to collect any escaping water. A small hose can also be attached to the
bleeding vent. Once the vent has been opened, water will initially escape
from the bleed hose and then air will follow after a few seconds. After the
air has escaped through the vent, it should be kept fully open for a further
five seconds.
The system should be bled:
• Before and during the first use of the stove.
• Daily for the following weeks until no more air escapes.
• When noises (air bubbles) can be heard in the heat exchanger.
• When the pressure of the home water provision is adjusted.
