SECTION 1
INTRODUCTION
The Vokèra Linea 24 & 28 are combined
central heating and domestic hot water appliances. By design they incorporate full sequence electronic ignition, circulating pump,
expansion vessel, safety valve, temperature
gauge, pressure gauge and 3 port diverter
valve.
They are produced as room sealed appliances suitable for wall mounting applications
only. They are provided with a fan powered
flue outlet with an annular co-axial combustion
air intake which can be rotated through 360
degrees. A vertical & twin flue option is available They are also suitable for S.E. duct installation.
These appliances are designed for use with a
sealed heating system only and are not intended for use on an open vented system.
The provision of stored domestic hot water is
possible by the addition of an indirect cylinder
with 'S' or 'Y' plan controls.
An automatic range-rating facility is incorporated in the boiler for the central heating system in conjunction with the electronic burner
modulation. The domestic hot water (dhw)
service utilises a motorised control combined
with a 3 port diverter valve to give hot water
priority which also benefits from a preheat
function.
