STRATA1
10.0 condense waste connection (contd)
If any part of the condense waste pipe is to be
run external to the building or is at risk of freezing,
then the pipe must be suitably insulated to protect
from freezing.
If a suitable drain for accepting the condense
waste is not available nearby to, and below the
boiler, (e.g. boiler installed in a basement below
ground level location), then a suitable condense
sump receptacle with a discharge pump should be
installed below the boiler to remove the condense
to a remote drain.
When making the condense waste pipe
connection to the boiler, do not use adhesives, it is
recommended to lightly apply a suitable jointing
tape (PTFE or similar) and use only light pressure to connect fittings to the appliance to avoid damage to
the condense waste outlet assembly.
It is recommended that the condense waste pipework should include a method of disconnection and
cleaning points.
11.0 flue/combustion
air connection - general
The flue connection and combustion air inlet
to the appliance are located on the top of
the appliance see fig 6. These connections are
arranged concentrically with the 80mm flue gas
connection centrally within the 125mm air inlet
connection. There are two options for flueing the
Strata 1 boiler.
i) Conventionally, using flue gas tube only and
air for combustion from the room or
compartment in which the appliance is installed. If
using a conventional flue arrangement then the
room or compartment must be ventilated in
accordance with the requirements of BS 6644 or
BS5440 as appropriate. For guidance on ventilation
see section 16.
ii) Room sealed using concentric 80/125
components or two seperate tubes where air for
combustion is taken from outside of the building.
When using a room sealed flue, where air for
combustion is provided from outside of the building
directly to the appliance, ventilation to a
compartment may still be required - See section 16
for general space cooling.

Important Note
Where the Strata 1 is to be installed in an application where the combustion air
is likely to be contaminated with oxidising agents, such as swimming pool areas,
special industrial processes etc, then the appliance must be room sealed.
