Introduction; Commissioning; Electrical Installation - Saunier Duval ISOFAST F 28 E Installation And Operating Instructions Manual

INTRODUCTION

The ISOFAST F boiler is a wall mounted modulating
combination boiler with electronic ignition providing
central heating and instantaneous hot water. The boiler
is equipped with a 4 litre domestic hot water storage
vessel that ensures maximum hot water temperature
stability during domestic demand.
The boiler is of the I2E+ category for use with Natural
Gas (G20) as distributed in the United Kingdom, or
Butane (G30), Propane (G31) or Towns Gas (G130) with
the appropriate conversion kit.
The boiler has a fan assisted balanced flue which both
discharges the products of combustion to and draws
the combustion air from the outside of the room.
The boiler is suitable for top outlet flue connection only
but, can be fitted with horizontal flue, vertical flue or
twin-pipe flue. Refer to flue catalogue for further de-
tails.
Both the central heating and domestic hot water tem-
perature are user adjustable from the boiler control
panel.
Domestic hot water demand always has priority over
heating demand.
The boiler is designed for use as part of a sealed water
central heating system with fully pumped circulation.
The pump, expansion vessel and associated safety de-
vices are all fitted within the boiler.
The boiler can be installed against either an external wall
or on an adjacent inside wall, that is, the flue system
