How to use
Install the radiator on a suitable load-bearing wall using the manufacturer-recommended wall brackets and fixings.

Usage recommendations
For optimal performance, fit thermostatic radiator valves and balance the heating system to ensure even heat distribution. Regularly inspect wall fixings and pipe connections for signs of corrosion or leaks, and purge air from the system seasonally or after maintenance.
