Combustion Air - Royal RHBH-153 Directions For Use Manual

It is prohibited to install the stove in bedrooms, small rooms and environments having potentially explosive dusts in the
atmosphere.

3.4 COMBUSTION AIR

!
During use, the stove withdraws a certain quantity of air from the environment
where it is located (except for products in the hermetic series, which can withdraw
air directly from the outside); this air must be reintegrated through an external air
intake (fig. 3 - PA = Air Intake).
If the rear wall of the stove is an external wall, create a hole for suction of the combusti-
on air at a height of approximately 20-30 cm from the ground, respecting the dimensio-
nal indications provided in the product technical sheet at the end of the
manual.
A non-closable permanent aeration grid must be placed external; in areas that are parti-
cularly windy and exposed to weathering, provide rain and wind protection.
Make sure the air intake is positioned so that it is not accidentally obstructed.
If it is impossible to create the external air intake in the rear wall of the stove (non-pe-
rimeter wall) a hole must be created in an external wall of the room where the stove is
positioned.
If it is not possible to create the external air intake in the room, an external hole can be created in an adjacent room provided
it communicates permanently with a transit grille. (fig. 4 - C = Box, G = Grille, S = Shutter)
The UNI 10683 standard prohibits the taking of combustion air from garages, combusti-
ble material warehouses or activities with the risk of fire.
If there are other heating appliances in the room, the combustion air intakes must gua-
rantee the necessary volume of air for correct operation of all the devices.
In the event that one or more extraction fans (suction hoods) are present and functio-
ning in the room where the stove is located, combustion malfunctions due to the lack of
combustion air could occur.
3.5 FLUE GAS EXHAUST PIPE
PRIOR TO INSTALLING THE HEATER AND OR THE FLUE GAS SYSTEM: ALWAYS MAKE SURE TO COMPLY WITH THE LOCAL AND
NATIONAL RULES!
The stove works with the combustion chamber in a vacuum, therefore it is essential to ensure the flue gas exhaust pipe is
properly sealed.
The stove must be connected to its own dedicated flue system, suitable in ensuring the proper dispersion of the combustion
products in the atmosphere.
The components that make up the flue system must be declared suitable for the specific operating conditions and provided
with CE marking.
It is mandatory to create a first vertical section of a minimum 1.5 meters to guarantee correct expulsion of the flue gases.
It is advisable to make a maximum of 3 changes of direction, in addition to that
resulting from the rear connection of the stove to the chimney, using 45-90°
bends or T-fittings (Fig. 5).
Always use a T-fitting with an inspection cap at each horizontal and vertical
variation of the flue gas exhaust pipe.
F
On the first T, at the exit of the flue gas outlet of the stove, it is necessary
to connect a pipe at the bottom in order to evacuate any condensate that
may form in the chimney (Fig. 5a).
The horizontal sections must have a maximum length of 2-3 m with an upward
slope of 3-5% (Fig. 5).
Anchor the pipes with suitable collars to the wall. The flue gas exhaust connecti-
on MUST NOT be connected:
- to a chimney used by other generators (boilers, stoves, fireplaces, etc.);
- to air extraction systems (hoods, vents, etc.) even if "intubated".
It is forbidden to install shut-off and draught valves. The exhaust of the combus-
tion products must be provided on the roof.
