Balanced Flue Kits - Trianco Contractor WM70 HE INTERNAL User, Installation, Commissioning & Servicing Instructions

BALANCED FLUE SYSTEMS
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
surface, through which to fit the terminal.
In addition to the siting benefit, the performance of balanced
flue boilers is virtually unaffected by high wind conditions as
the wind pressures are applied equally to both the air intake
and discharge points, thus creating a balanced condition.
Whereas some balanced flue boilers rely on case sealing to
achieve a room seal, the Contractor WM70 HE has a sealed
air duct system which maintains room sealed performance
even when the casing is removed for burner commissioning
and service.
The use of the balanced flue principle also enhances the
overall thermal efficiency of the boiler, as the incoming air
extracts waste heat from the flue and returns it as pre-
heated air to the burner to aid combustion.
Balanced-flue condensing boilers are designed to operate at
low noise levels.
INSTALLATION NOTES
1. At certain times during operation, a plume of
condensation will be produced from the terminal. When
positioning, this should be taken into consideration to
ensure a nuisance is not caused to neighbouring
properties.
2. The flue terminal should not be positioned where the
products of combustion could enter the building (refer to
fig 20 for guidance).
3. Keep the terminal clear of infra-red sensing devices
such as those used to control security lighting.
4. Positioning of the terminal below a balcony or carport
should be avoided.
5. As the system operates under positive pressure, it is
essential that all flue joints are sealed correctly.
6. Only 28. second kerosene class C2 to BS 2869 has
been tested for use with this appliance.
Note: Trianco balanced flue kits have been designed and
tested exclusively for use with Trianco boilers. As
such, compatibility with other makes of boiler
cannot be guaranteed.
