INSTALLATION
Essential recommendations for the correct operation of the appliance
•
The boiler must be mounted on a non-flammable surface.
•
Noise may be amplified when the appliance is mounted on a lightweight material
wall. Using rubber dampers may reduce this effect.
•
Make sure the appliance support bracket is level at installation.
Install the appliance using the provided mounting bracket:
Refer to "Wall mounting - dimensions" on page 17 for the installation dimensions.
1. Drill two holes with a depth of 75 mm using a 10 mm drill bit, at the required height and follow-
ing the spacing given below.
2. Fasten the wall mounting bracket using the supplied lag screws.
3. Attach the boiler to the wall mount.
BOILER INSTALLATION - WALL MOUNTING
The heating circuit must be designed so as to ensure a continuous flow in the boiler; this
flow may be obstructed if all the thermostatic valves are closed. In this case, install a bypass.
For additional system configurations, refer to "Configuration and system set-up" on page
35 and to the Installer’s Handbook (or the ACVMax System Control manual, depending
on the boiler build, refer to page 3).
