The maximum heat output of this boiler can be adjusted to suit the exact
requirements of the building. The process of adjusting the maximum
heat output is commonly referred to as range rating. The new boiler is set
at the maximum output and should be adjusted when it is installed and
commissioned. In accordance with the standards, the declared space
