3.15.2 - START-UP
IGNITION
Ensure the checks referred to in point 3.15.1 have
been performed.
Once the air has been adjusted in accordance with
paragraph 3.15.3, close the bottom door and power
the electric control board.
The first ignition of the new boiler could be difficult
due to moist refractory cement casting.
Accordingly, we advise opening the primary air well and lowering
the secondary air.
Open the top loading door and place some dry wood kindling
crosswise on the main stone, above the central slot.
Use highly flammable material, and avoid large and square logs.
Light the wood using thin sheets of paper (newspaper or the like).
Leave the top door ajar and turn on the fan.
Wait a few minutes for the fire to light and produce embers (5 -
10 minutes approximately).
After a few minutes, if looking through the flame sight glass of
the lower door you see that flame inversion is beginning, add
other larger logs.
Close the top door.
T
he wood must have the following length:
a) 50 cm (+ 1 cm, - 4 cm)
for model NOVAIREX 34
b) 50 cm (+ 1 cm, - 4 cm)
for models NOVAIREX 45
c) 70 cm (+ 1 cm, - 4 cm)
for model NOVAIREX 55
These measurements must be strictly observed
.
As even wood feeding is essential for good combustion, it is nec-
essary to ensure the length of the wood logs fed, their shape and
the manner of loading do not prevent regular feeding of the fuel.
The wood logs must be placed lengthwise and horizontally. No
log should be tilted or placed sideways.
Once you have checked flame inversion, it is possible to proceed
with further loading (bear in mind that the primary and secondary
air adjustment indications in the table are approximate).
FURTHER LOADING
Before loading wood once again, consume the previous one as
much as possible.
You can add more wood when the bed of embers in the firewood
compartment has reduced to about 5 cm deep.
Open the top loading door and the internal anti-smoke door
slowly.
It is necessary to use wood logs with the length stated in the
previous paragraph.
Place the new wood logs as described above.

USEFUL TIPS AND WHAT TO AVOID
- Logs which are too long do not fall down properly and can
cause "bridges".
- Logs which are too short cause irregular air ducts, with con-
sequent reduction in output and efficiency.
- If the quality of the wood causes "bridges", it could become
necessary to load logs cut in half so that the total length “L”
is as indicated in the previous paragraph.
To avoid the formation of "bridges", it is unadvisable to place
logs against the side walls of the wood storage compartment.
(see fig. 3).
- 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 chamber door.
