Flue Connection - Kalfire W60/51Fl Installation And Instructions Manual

Use of openings
if you do not want to use grills, openings at the top and base of
the surround (chimney breast) are also sufficient. for throughput
openings, see Table 2. These openings serve the same function as
the gratings and supply and extract the convection air. we advise
you to place tubes or hoses onto the outlet openings. This makes
the convection system (just a little) more powerful and the heat is
guided more easily to the openings.
WARNING if you do not use the recommended convection
set, the Kalfire may be damaged by overheating and
the room may experience strong discolouration. There
is always a risk of discolouration, but this risk can be
considerably reduced, by correctly ventilating the room.
DANGER! Mount the grills at a distance of at least 30 cm
from the ceiling or wall. ensure there are no flammable
materials closer than 30 cm next to and 50 cm above the
gratings.

5.4 Flue connection

Calculate the flue duct using the calculation values of the
chimney calculation. a chimney calculation is made for the
roof pass-through and the wall pass-through. The chimney
calculation is suitable for the Kalfire w. Kalfire cannot guarantee
the proper functioning of the fireplace if your configuration does
not comply with the chimney calculation.
CAREFUL! Many elbows and/or horizontally-mounted
components of the flue duct can create substantial
resistance.
Connecting the fireplace to the existing chimney. The operational
height of the flue must be at least 4.5 metres (draught 12 pa),
calculated from the point where the flue duct is installed on the
fireplace.
WARNING Take local legislation and environmental factors
into account.
