COMPARTMENT INSTALLATION

Due to the low casing temperatures generated by the boiler, no compartment ventilation is
required. However, the cupboard or compartment must not be used for storage.
3.11

CONDENSATE DRAINAGE

Being a condensing boiler, the Qudos 28h and Qudos 28hP are fitted with a condensate
trap at the base of the heat exchanger and flue assembly, with facility to connect to a
drain point underneath the appliance.
The condensate trap is packed loose with the appliance and MUST be fitted
and secured BEFORE firing the appliance
Use only plastic piping and do not reduce below 15 mm internal diameter within the
dwelling. Condensate should preferably be drained into the sanitary waste system or,
alternatively, the rainwater system of the property in most cases. Ensure in all cases that
the disposal of the condensate is in accordance with any local regulations in force.
Termination of the pipe must be either at a branch or stack internal to the house, or
externally at an open gully. Alternatively, discharge into a purpose made condensate
soakaway can be considered. Existing or purpose built drains must use suitable corrosion
resistant material as condensate is mildly acidic.
The connection to the condensate drain of the boiler, and the condensate drain pipework
itself, should be properly sealed to ensure there is no possibility of leakage into the
dwelling.
A minimum slope downwards towards the drain of 1 in 20 is essential. Freezing of the
termination and pipework must be prevented. Any drainage pipes outside the property
must be at least 32 mm inside diameter.
