HIGH EFFICENCY 

CONDENSING SYSTEM INNOVATION AUTOMATIC MODULATING BOILER

FOR CENTRAL HEATING AND DOMESTIC HOT WATER

This new super high effi cient turbo-modulating boiler is designed to meet domestic hot water and central heating requirements 
at super high effi ciency, unheard of only a few years ago.

POSITION

The appliance is extremely versatile as it can be fi tted in almost any room. The appliance is room sealed, there is no contact 

between combustion chamber and living accommodation. This guarantees maximum safety and effi ciency. Indeed, our 
depression/combustion front cover has been designed to fi t, achieving maximum air tight seal using screw down fasteners at 
15 cm. This should not hinder service of the appliance, but does ensure maximum effi ciency and safety - something which we 
at Ravenheat take great pride in.

Each boiler has been designed and manufactured in our modern plant to exacting ISO 9001 discipline, all boilers carry full CE 

marking of approval. Technical sales and commercial service are available throughout the UK. This product is guaranteed by 
Ravenheat Manufacturing, Chartists Way, Morley, LEEDS, LS27 9ET. Telephone No (0113) 252 7007.

BASIC COMPONENTS - (See fi gure 1)

Guarantee is a full 12 months from date of purchase providing the appliance has been fi tted in accordance with these instructions 

and relevant codes of practice.

valve.

Variable head pump suitable for any type of central heating system.

- Burner 

with 

fl ame stabiliser designed to operate under all thermal conditions.

Primary heat exchanger constructed from stainless steel.
