CONDENSING SYSTEM INNOVATION AUTOMATIC MODULATING BOILER

FOR CENTRAL HEATING AND DOMESTIC HOT WATER

This new high effi cient turbo-modulating boiler is designed to meet domestic hot water and central heating requirements at 
super high effi ciency.

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 the 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 
every 15 cm .  This should not hinder service of the appliance, but does ensure maximum effi ciency and safety - something 
which Ravenheat takes great pride in.

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

CE marking of approval. Technical sales and commercial service are available throughout the UK. This product is guaranteed
