USEFUL SUGGESTIONS and LOADING ERRORS TO BE
AVOIDED
- Logs too long do not fall down properly and can cause
obstructions.
- Logs too short cause irregular air passages, with consequent
reduction in output and efficiency.
- In case the quality of the wood causes “obstructions” it could
become necessary to cut the wood logs in two parts, as shown
in fig. 49, in order that the total length “L” is as indicated in the
previous paragraph.
- Always open the upper door slowly in order to avoid blowbacks
and smoke formation.
- During normal boiler operation it is absolutely forbidden to
open the lower combustion door.
4.7 - COMBUSTION AIR ADJUSTMENT
PRIMARY AND SECONDARY AIR ADJUSTMENT
The boiler AIREX has a combustion air intake
fan (POS. 7 fig. 2), a distribution collector of the
combustion air (POS. 1 fig. 27) and regulators of
primary air (POS. fig. 27) and secondary air
(POS. S fig. 27).( N°2 fan for the models AIREX
652S and AIEREX 802S + N°2 collectors
primary and secondary air inlet with its
regulations, see fig.28)
At first start you need to adjust the primary and secondary
air, bearing in mind that the primary air determines the
power of the boiler and therefore the amount of wood that is
burned, and the secondary air completes the combustion.
It is necessary for proper regulation of air according to the
wood used and its actual moisture, observe the flame
through the inspection glass placed on the lower door.
The flame will fill about two-thirds and the lower chamber will
have to lick the bottom cradle quietly, without too much
dragging of ash, and without noise. The flame will have an
orange-pink-white, be not too clear with the center tending to
blue.
To carry the flame in optimum conditions you should then
adjust the primary air by turning the knob (pos. P), it will
operate similarly for the secondary air (pos. S).
Example n.1
Thick, wet wood logs = difficult combustion
S - Very closed (try to get the maximum dimension of the flame,
but not a reddish colour).
P - Reasonably open in order to obtain a sufficient gasification.
Example n. 2
Very inflammable wood logs
S - Completely open.
P - Slightly closed to reduce the gasification, but sufficiently
open to evacuate the ash that can close the combustion head.
