The
Mynute VHE
is a high-efficiency boiler for open vent
system.
These appliances – by design – incorporate premix
combustion and a radial aluminium heat exchanger.
The
Mynute VHE
range are produced as room sealed,
category II2H3P appliances, suitable for internal wall
mounting applications only. Each appliance is provided
with a fan powered flue outlet with an annular co-axial
combustion air intake that can be rotated – horizontally –
through 360 degrees for various horizontal or vertical
applications. The Mynute VHE can also be used with the
Vokera twin flue system.
These appliances are designed for use with an open-vent
system; consequently they are not intended for use on
sealed or pressurised systems. Please contact the Vokera
technical helpline for advice should you wish to use the
Mynute VHE on a sealed/pressurised system.
This booklet is an integral part of the appliance. It is
therefore necessary to ensure that the booklet is handed
to the person responsible for the property in which the
appliance is located/installed. A replacement copy can
be obtained from Vokera customer services.
