2 .8 Room-sealed connection pipe
C13, C33, C53
The connection pipe must be removable.
By design, the boiler's smoke temperature cannot
exceed 120 °C, therefore, there is no need to add an
evacuation pipe protection thermostat.
The boiler must be connected:
• Either to a horizontal oxidising air intake and combustion
product evacuation mechanism (C13 type).
• Either to a vertical oxidising air intake and combustion
product evacuation mechanism (C33 type).
• Or to separate air intake and smoke evacuation pipes
(C53 type).
Characteristics of the suction elements to be used
(see characteristics table page 7 ).
The use of aluminium connection pipes is prohibited .
2 .8 .1 Concentric horizontal room-sealed pipe
(C13 type)
Regulations
The evacuation pipe must lead directly to the outside
through a wall.
The air intake and burnt gas evacuation opening must
be placed at least 0.40 m away from any opening
windows and 0.60 m away from any ventilation air
intake openings.
If the evacuation leads onto a public or private road, it
must be protected from any external interventions likely
to harm its normal operation.
When the terminal leads out over a horizontal surface
(ground, terrace), a minimum distance of 0.30 m must be
respected between the base of the terminal and this surface.
Recommendations
Respect the max authorised lengths ( figure 20, page 22 ).
- Horizontal sections must be avoided on the evacuation
pipes.
- Respect a minimum slope of 5% downwards and
towards the boiler.
- Make sure that the air intake and smoke exit circuits
are perfectly sealed.
Mounting the room-sealed pipe
Plug the different elements into each other (terminal,
pipe, elbow, etc.). Coat the seal with liquid soap to make
it easier to plug in.
- Adapt the pipe length.
- Use long extensions to limit the number of junction
pieces.
- Refer to the supplier's instructions.
- Determine the boiler's position in relation to the suction
pipe output
- Drill a hole 150 mm in diameter in the wall
- Insert the pipe assembly into the hole in the wall and
connect it to the boiler's adaptor, making sure it is sealed.
- Seal the pipe terminal into the wall using polyurethane
foam to enable it to be removed if necessary.
- Provide a telescopic element to enable the smoke
outlet to be removed during maintenance operations.
