Tips
•
Use enough wood to ignite the Kalfire:
- Kalfire W45/48F ca. 2 kg
- Kalfire W70/33F ca. 3 kg
- Kalfire W60/51F, W85/40F, W65/38C,
W66/48S, W90/47C, W90/47S ca. 4 kg
- Kalfire W71/62F, W100/61F, W105/47F,
W80/52T en W105/47T ca. 6 kg
•
When the fire has been lit, leave the door slightly open (1-2
cm) for a few minutes; the wood will catch fire more easily
and the flue will be quickly warmed-up.
Do not use white spirits, petrol, oil or other liquid fuels.
Be aware that weather conditions (air pressure, temperature,
wind) can influence combustion. Minimize these influences by
adjusting the secondary air supply.
5.6 Optimal heat output
For optimal heat production we advise you to burn wood
according to the instructions below. This will achieve the same
performance and emission values, obtained during inspection of
the appliances.
•
Ensure a glowing bed is created (see section 5.5).
•
Use logs of wood of approximately the same size. The
amount differs per Kalfire W model. See table below.
