The primary air must be open during starting, until the wood is properly started, i.e., all the regulator
is in the (+) position. On the side cover, there is a mark indicating the point from which the primary
air is completely closed and part of the secondary air is open.
After igniting, and for good combustion, the regulator should be between the markings, as you can
see in Figure 30.

The secondary air also has the function of cleaning the glass, creating a sweeping effect through the
passage of preheated air over the entire interior surface of the glass, helping to keep the glass cleaner
for longer.
6.5. Energetic efficiency and performance ratings
* The implementation of solutions promoting greater energy efficiency results in a substantial
reduction in energy needs, which in turn helps reduce our current dependence on fossil fuels and other
non-renewable sources of energy. Energy efficiency therefore encourages significant savings, both
economically and environmentally speaking.
* Solzaima's commitment to developing energy efficient heating units results in products that can
claim to have an efficiency rate equal or above 70%. A 70% efficiency rate means that 70% of the
energy contained in the firewood is used to warm your home or, in other words, you are able to
produce the same amount of energy with much less firewood. A Solzaima unit of 5kW with an
efficiency rate of 75% is expected to consume approximately 1,6 kg (3,5 lbs) of firewood per hour to
heat a 35 m
2
(377 sq ft) room.
* Generally, the efficiency rate of a traditional fireplace is only about 10%, which means it will need to
consume approximately 12 kg (26,5 lbs) of firewood to produce the same 5kW required to warm the
same 35 m
2
(377 sq ft) room.
