INTRODUCTION

The ECOSY 24 E and ECOSY 28 E boilers are wall mounted combination boilers providing central heating and instantaneous hot water.

The ECOSY SB 24 E and ECOSY SB 28 E boilers are wall mounted system boiler providing central heating only.

The ECOSY 24 E and ECOSY SB 24 E boilers are of the II2H3+ category for use with Natural Gas (G20) and Liquide gas (G30 and G31)as distributed in the United Kingdom.

The ECOSY 28 E and ECOSY SB 28 E boilers are of the I2H category for use with Natural Gas (G20) as distributed in the United Kingdom.

The boilers have 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 boilers are 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 details.

On ECOSY 24 E and ECOSY 28 E, both the central heating and domestic hot water temperature are user adjustable from the boiler control panel.

On the ECOSY 24 E and ECOSY 28 E, 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 devices 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 will pass directly to the rear or to either side to the terminal fitted on the outside wall face.

The installation must be carried out by a competent person in accordance with the relevant requirements of The Building Regulations, The Water Byelaws, The Building Standards (Scotland) Regulations and any applicable local regulations.

These instructions should be carefully followed for the safe and economical use of your boiler.

Ancillary equipment

A range of flue accessories are available including vertical flues, twin-pipe flues, bends etc. For further information contact your supplier.

On ECOSY SB 24 E and ECOSY SB 28 E, the central heating temperature is user adjustable from the boiler control panel.
