IMPORTANT: 

 

These appliances are CE certificated for 
safety and performance. It is therefore 
important that no external control devices e.g. 
flue dampers, economisers etc., are directly 
connected to this appliance unless covered 
by these Installation and Service Instructions 
or as otherwise recommended by  Ravenheat 
in writing. If in doubt please enquire.

 

Any direct connection of a control device 
not approved by Ravenheat could invalidate 
the certification and the normal appliance 
warranty. 

 

It could also infringe the Gas Safety 
regulations and the above regulations.
