Installation; Placement; Working Of Combustion Air - Kalfire W60/51Fl Installation And Instructions Manual

5 Installation

WARNING always use adequate personal protective
equipment (gloves, safety goggles and work clothing)
during installation and maintenance of the fireplace.

5.1 Placement

installation is prohibited in the following situations:
•
in stairwells, with the exception of buildings with no more
than two residences;
•
in entrances that are accessible to everyone;
•
in spaces where highly flammable or explosive substances
or mixtures are processed, stored or manufactured;
•
in rooms or homes that are vented by air conditioning or air
heating by fans, with the exception of the following cases
where the risk-free functioning of the Kalfire is guaranteed:
- The installation only circulates air within the room;
- The installation has reliable safety provisions, so that
excess pressure is automatically created in the room with
the installed fireplace;
- The combustion air flow from the fireplace and the volume
flows of ventilation installations in the room and in the
rooms connected via venting airways create negative
pressure that remains below 0.04 mbar.
- Careful! This situation must also be safeguarded if easily
accessible control equipment used for the ventilating
installation is moved or removed.
- fresh air is supplied via the air supply system to operate
the flue gas discharge system (e.g. through an open
window or a fresh air supply).

5.1.1 Working of combustion air

when the door is closed, the fire extracts the combustion air
directly from the connection at the rear (a) or bottom (a').
This combustion air is guided into the combustion
chamber via de secondary air regulation (b) and the primary
thermostat (C), where it is used as primary or secondary
combustion air.
Primary combustion air (P)
The thermostat automatically regulates this airflow.
with a cold fireplace, the thermostat ensures that the air
enters the combustion chamber via the lower spoiler. as the
fireplace warms up, the air flow will gradually decrease. after
approximately 50 minutes, the fireplace will be so hot that this
airflow stops. The primary air regulation is 100% automatic and
cannot be influenced.
Secondary combustion air (S)
You control this airflow manually by moving the secondary air
regulation. This air, which is warmed up via risers to the left and
right of the combustion chamber, is guided to the combustion
chamber via the upper spoiler.
16
CAREFUL! never entirely close the secondary air
regulation. without airflow from the secondary air control,
the fire can suffocate, causing the fireplace's glass pane to
become soiled more quickly.
when the door is open, the air requirement of the fireplace
changes. a large volume of air will be sucked in through the large
opening at the front. This air will be taken from the room where
the fireplace is located.
when the door is open, the built-in fresh air valve ensures that the
passage of the air to the combustion chamber is closed from the
rear or bottom connection (see figures 14 - 16). instead, the air is
diverted to the convection casing, after which it flows heated into
the room.
The air can then be used for the combustion process.
