OUTLET AIR
INSTALLING THE OUTLET AIR PIPE
It is important to ensure that the pipe has a minimum diameter of 110 mm all the way from the toilet to the
ventilator cowl. The inside of the pipe must be smooth, preferably of a PP- or CPVC-type. Do not use any flexible ducts or pipes
when installing the Cinderella toilet. The supplied ventilator cowl must always be used.
Specifications and guidelines for installing the Cinderella Comfort Toilet:
•
Maximum length horizontal pipe: 600 mm
•
Maximum length vertical pipe without any bends: 5.5 metres
•
Maximum length vertical pipe with bends: 4.5 metres
•
If you have 2x 30° bends: Total length of angled pipe must not exceed 1.5 metres
•
If you have 2x 45° bends: Total length of angled pipe must not exceed 1 metre
The pipe must be installed vertically above the roof and extend at least 600 mm above the roof surface (fig. 2). If the outlet
air pipe is to be enclosed (e.g. using metal siding), make sure that the end of the pipe extends at least 400 mm above the
enclosure (fig. 7).
IMPORTANT NOTE:
If the pipe perforates the roof surface, ensure that it is in compliance with building regulations.
IMPORTANT NOTE:
Never use a fine mesh net in the ventilation pipe as this might restrict the airflow in the system.
IMPORTANT NOTE:
Each Cinderella Comfort toilet must have its own outlet air pipe.
IMPORTANT NOTE:
The supplied T-piece should always be used. Do not use any 90° bends in addition to the T-piece.
The T-piece must be accessible when installed, so that the drainage pipe can be rinsed, and the outlet
pipe cleaned.
Alternative 1:
When the outlet air pipe is installed through an exterior wall,
the toilet should be placed a minimum of 25 mm from the
wall. If you are placing the air inlet vent on the wall behind the
toilet (optional positioning), please ensure to leave enough
space to allow the vent to be fully opened. This will normally
require the toilet to be placed approx. 140 mm from the
wall. (fig. 4).
Alternative 2:
When the outlet air pipe is installed indoor through the
ceiling, the toilet should be placed a minimum of 230 mm
from the wall, to make room for the T-bend (fig. 5).
