The Linea HE range of appliances is comprised of 3
models of high-efficiency combination boiler with in-
puts to heating & DHW of 25 & 30, 30 &35 and 35&35 kW
respectively. Each appliance – by design – incorporates
electronic ignition, circulating pump, expansion vessel,
safety valve, water pressure sensor and automatic by-
pass.
The Linea HE range is produced as room sealed,
category II2H3P 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 that can be rotated – horizontally – through 360
degrees for various horizontal or vertical applications. The
Linea HE range can also be used with the Vokera twin flue
system.
The Linea HE range is approved for use with B23P-B53P-
C13-C23-C33-C43-C53-C63-C83 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 nor are they intended for external
applications.
