CHIMNEY COWL

The chimney draft also depends on the chimney cowl.
The chimney cowl should assure the smoke discharge even during windy days, having into account that it must exceed the top of the roof
(drawing D4.6).
The chimney cowl must comply with the following requirements:
• It must have the same interior section of the chimney.
• It must have a usable exit section that is two times the one of the interior of the chimney.
• It must be constructed so that the rain, snow or any other objet do not enter inside.
• It must be easily accessible in order to do servicing and cleaning tasks.
It the chimney cowl is metallic, due to its own design adapted to the diameter of the pipe, the smoke discharge is assured. There are different
models of metallic chimney cowl, fixed, anti-return, and rotary or extractor.

OUTSIDE AIR INTAKE

For the proper operation of the insert, it is essential that there is air enough for the combustion and re/oxygenation of the environment where it
is installed. In the case of houses built under the requirements of "energy efficiency" with a great degree of air tightness, it is possible that the
air intake is not guaranteed *the fitter must assure compliance with the Technical Building Code. This means that the air must be able to move
for the combustion through some openings connected to the exterior, even when doors and windows are closed. Moreover, it must comply
with the following requirements:
• It must be placed in so that it cannot be obstructed.
• It must be connected to the environment where the equipment is installed and it must be protected by a grate.
• The minimum area of the outlet should not be less than 100 cm2. Check regulations on this issue.
•
When the air flow comes through openings that are connected to the exterior of adjacent environments, it is important to avoid
air intakes in connection with garages, kitchens, toilets, etc.
The Hydronova Plus model has the possibility to choose that the primary air inlet comes from an adjacent environment or even from outside
the house.
In the case of providing air from the outside or from an adjacent environment, you must purchase the optional kit (KIT-AIR3) of external air
intake (hermetic). You simply have to connect this KIT with a 120 mm diameter conduction and the chosen place. Keep in mind that if it is
too long or has too many deviations (elbows), it is far from benefiting the air intake, it causes a large loss of load and therefore can cause
combustion problems.
The procedure for installing the optional external air intake kit is as follows.
D5.1
- Remove the lower metal piece below the door, this piece is hanging on the front of the stove, just move the piece up and remove it.
(see drawing D5.1).
- Position the kit under the combustion chamber. You must centre the kit, and screw it with the 4 screws that you will find in the lower part
of the combustion chamber (see drawings D5.2 and D5.3).
- Break the rear plate on the lower back part of the stove, which is partially perforated, so that it allows you to connect the kit to the
outside or the chosen environment, through a conduction of 120 mm of diameter. (see drawing D5.4).
- Replace the lower metal part under the door to hide the kit.
