*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
