The
Mynute i
are high-effi ciency system boilers with outputs of
20kW and 30kW. These appliances – by design – incorporate
electronic ignition, circulating pump, expansion vessel, safety
valve, pressure gauge and automatic by-pass.
The
Mynute i
range is produced as room sealed, category
II2H3P appliances, suitable for internal wall mounting applica-
tions 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. The
Mynute
i
can also be
used with the Vokèra twin fl ue system.
The
Mynute i
is approved for use with C13 & C33 type fl ue
applications.
These appliances are designed for use with a sealed system
only; consequently they are not intended for use on open
vented systems.
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 Vokèra
customer services.
