The
Mynute VHE
comprises a range of high-effi ciency
open-vent boilers with outputs ranging from 12 to 20kW.
These appliances – by design – incorporate premix
com-
bustion and a radial aluminium heat exchanger.
NOTE
This booklet relates specifi cally to the Mynute 15VHE only.
The
Mynute 15VHE
are produced as room sealed,
category II2H3P appliances, suitable for internal wall
mounting applications only. Each appliance is provided
with a fan powered fl ue outlet with an annular co-axial
combustion air intake that can be rotated – horizontally
– through 360 degrees for various horizontal or vertical
applications; in addition, there is also a facility to re-
confi gure the fl ue outlet from a top outlet to rear outlet.
The
Mynute VHE
can also be used with the Vokera twin
fl ue 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.
