6.6 Optimal heat output
once you have the fireplace lit and it is at a comfortable
temperature, observe the following instructions for optimal heat
output (this will achieve comparable performance and emission
values as obtained during the inspections of the Kalfire w):
•
ensure a glowing bed is created (see section 6.5).
•
use logs of wood of approximately the same size. The
amount differs per fireplace model, see the table below.
rule of thumb: 1 kg of wood provides about 4 kw of energy.
The fireplace is suitable for discontinuous use. This is achieved by
burning according to Table 7.

6.6.1 Topping up with wood
as soon as the fireplace is at a comfortable temperature
(see section 6.5), you can replenish the wood in the fireplace.
To achieve optimal heat output:
•
top up the fire with new wood as soon as the flames
have disappeared and the logs are beginning to glow
(no smoke development).
•
open the door slowly to prevent smoke escaping into
the room because of the sudden draught.
•
do not add more than 2 to 3 logs (for maximum weight,
see Table 6).
place the logs as follows:
Kalfire W45/48F
place the two logs into a v-shape. The Kalfire w45/48f can be
used both as an open or a closed fireplace.
remove both baffle plates before using the fireplace with the door
open, to enable correct exhaust of the flue gas.
