The Syntesi range of appliances is comprised of 3 models
of high-efficiency combination boiler with outputs to
heating & DHW of 24, 28, & 34kW respectively. Each
appliance – by design – incorporates electronic ignition,
circulating pump, expansion vessel, safety valve, pressure
gauge, and automatic by-pass.
The Syntesi range is produced as room sealed, category
II2H3+ appliances, suitable for internal wall mounting
applications only. They are provided with a fan powered
flue outlet with an annular co-axial combustion air intake
INTRODUCTION
that can be rotated – horizontally – through 360 degrees
for various horizontal or vertical applications. The Syntesi
range can also be used with the Vokera twin flue system.
The Syntesi range is approved for use with C12 & C32
type flue applications.
These appliances are designed for use with a sealed
system only; consequently they are not intended for use
on open vented systems.
