Trianco EuroStar Premier 100/125 Condensing, User, Installation, Commissioning & Servicing Instructions, Page: 19 / 28

INSTALLATION NOTES
(a) Balanced-flue condensing boilers are designed
to operate at low noise levels. During operation,
a plume of condensation will be produced at
certain times from the terminal. When positioning,
these factors should be taken into consideration
to ensure that they do not cause a nuisance to
neighbouring properties. It should also be
positioned to avoid the products of combustion
from entering the building.
(b) Keep the terminal clear of infrared sensing
devices such as these used to control security
lighting.
(c) Positioning of flues under balconies and carports
should be avoided.
(d) As the system operates under positive pressure,
it is essential that all flue joints are sealed correctly.
(e) Only 28 sec. Kerosene Class C2 to BS 2869 is
permitted for use with this appliance.
Note Trianco balanced flue kits have been designed
exclusively for use with Trianco boilers and as such,
compatibility with other makes of boiler cannot be
guaranteed.
Balanced Flue Systems
(optional extra)
The Trianco balanced flue system offers much greater
flexibility for siting, the boiler compared with a
conventional chimney. The only requirement is for a
suitable outside wall to fit the horizontal discharge
terminal or, alternatively, a single storey roof for a vertical
discharge.
In addition to the siting benefit, the performance of
balanced flue boilers is virtually unaffected by high wind
conditions since the wind pressures are applied equally
to both air intake and flue gas discharge, thus creating a
balanced condition.
Whereas some balanced flue boilers rely on case sealing
to achieve a room seal, Trianco boilers have a sealed air
duct system which maintains the room sealed
performance even when the casing door is removed for
burner commissioning or adjustments.
The use of the balanced flue principle also enhances the
overall thermal efficiency of the boiler since the incoming
air extracts waste heat from the flue and returns it as
pre-heated air to the burner where it aids combustion.

Note (1) The terminal should be positioned so as to avoid
products of combustion entering the building.
Note (2) If the terminal is less than 2 metres above the
ground level, balcony or place to which any
person has access, the terminal must be
protected by a guard.
Note (3) The flue must be positioned so that it does not
cause nuisance and permits the dispersal of
combustion products.
