Foreword / Our philosophy with regard to 

quality 

 

You have decided to purchase a Spartherm product – we would like to 
thank you for placing your confidence in us. 
 
In a world characterised by excess and mass production, the good name 
of our firm is inextricably linked to the credo of our owner, Gerhard 
Manfred Rokossa: 
“High technical quality combined with modern design and on-site 
customer service carried out to the latter’s full satisfaction, in the 
expectation that the customer will then recommend us to others.”  
 
To you and our partners in specialist dealerships, we offer first-class 
products that stir the emotions, appealing to that sense of security and 
comfort that we all feel. However, to ensure that we succeed in this, we 
recommend that you read the operating manual carefully to quickly 
familiarise yourself with your fireplace insert in all its details. In addition to 
information on how to use it, this manual also contains important 
maintenance and operating instructions for your safety and to ensure your 
fireplace insert retains its value.  
 
It also contains valuable tips and advice to help you. In addition, we show 
you how to use your product in a way that will protect the environment.. 
 
If you have any further questions please contact your dealer. 
 
A beautiful fire at all times. 
Your Spartherm team 
G.M. Rokossa
