A.-Lighting up for the first time
Once installed in its final position, check that all joints have been sealed to prevent
outside air from entering, which would affect the draw.
Before lining the fireplace with bricks or any other incombustible material, check that it
works correctly.
We recommend a slow fire for 3 to 4 hours when lighting-up for the first time. This will
help stabilise the different components and avoid any possible breakages.
It is advisable, when lighting the fireplace for the first time, to open windows to let any
fumes or odours that may be caused by the combustion of the protective paint solvents or any
other material to escape.
B .- Primary air. Regulation
The provision
combustion process is performed by means
of the primary air valve. (See fig. 4)
To favour lighting-up the fireplace and
to avoid the formation of tar, we recommend
opening the primary air valve completely to
allow the inflow of abundant air for the
combustion process.
This situation must be maintained at
the beginning of each lighting-up process in
order to heat the fireplace and chimney,
which will avoid
condensation and creosote.
It is essential to provide an abundant
load of fuel when lighting. The following
loads will depend on the heat requirement
desired.
Once the fireplace is hot, you may regulate
the provision of air for the combustion
process.
COMMENT:
Due to its air-tightness and heat circulation
of the Built-in Fireplace H-03 during normal
situations, we recommend opening the door
of the fireplace slowly when you have to add
more fuel.
C.- Secondary air. Self-cleaning
The purpose of secondary air for the combustion process is to provide additional air to
burn any un-burnt matter after the primary combustion process due to a lack of oxygen.
This extends the combustion process and improve the performance of the device.
The provision of secondary air is through the top opening in the BUILT-IN FIREPLACE
H-03 and is aimed at the glass pane on the door, creating a layer of air that will prevent soot
from adhering to the said pane. (Self-cleaning) (See Fig.-3)
