IMPORTANT SAFETY NOTES 

 

 

INTRODUCTION 

 

The Aztec Mini Electric Combination and System Boiler is a wall mounted electric central heating boiler 
designed with smaller properties in mind. Access is required to the front of the boiler for servicing. Once the 
boiler is switched on it is fully controlled by an automatic management system which monitors the safety and 
running functions of the boiler. Designed to work on a fully pumped wet system only. The boiler produces hot 

water by passing water over electric heating elements housed in an insulated heat exchanger. 
The boilers incorporate inverter constant temperature technology which automatically adjusts output to 
match demand. 

 

 

 

Read these instructions before installing your boiler. 
  

The heating system must comply with the latest editions of British Standards 5449 and The Building 

Regulations, and Electrical Wiring Regulations BS 7671. 
 

1.

 

Always switch OFF the electrical supply before removing the cover.  

2.

 

If any part of the boiler is modified, then the warranty will be invalidated.  

 

We recommend that you keep these instructions in a place near your appliance for easy reference.
