*NOTE: The boiler can be operated with a clearance of 5mm at the right. This is also sufficient for routine maintenance.

However a clearance of 20mm is required if it is necessary to remove the secondary heat exchanger. This should be considered when siting the appliance and in the event of any subsequent alterations in the area of installation
