Leave one boiler length (x1) of space in front of the
boiler door to extract the turbulators (if fitted) and for
cleaning.
Observe the stated dimensions to ensure straightfor-
ward installation and maintenance.
Observe the clearances with regard to the regulations
applicable at the installation site. Allow for equipment
and accessories.
The installation surface must be level. Level the boiler
horizontally.
