INSTALLATION OF THE HEAT EXCHANGER
2.1
Installation site
•
Heat exchangers must be installed in accordance with the rules of the art and the standards in effect.
•
The heat exchanger should be installed as close as possible to the boiler in order to minimise heat loss.
If this is not possible, you will need to lag the primary circuit pipes with thermal insulation.
•
For optimum heat exchange, the flows in the primary circuit and secondary circuit must cross within the
exchanger.
•
The heat exchanger must be connected directly to the boiler's hot water production system. It should
under no circumstances be plumbed into an existing network (radiator circuit, residential hot water
supply circuit, etc.).
•
To mount the heat exchanger, use the support plate as a template to mark out the 4 holes that need to
be drilled in the wall.
