= A room sealed appliance designed for connection via ducts to a horizontal
or vertical terminal, which admits fresh air to the burner and discharges
the products of combustion to the outside through orices which, in this
case, are concentric. The fan is upstream of the combustion chamber.

2H3P
= Appliances capable of using gases of Group H and gases of Group P.
* The value is used in the UK Government’s Standard Assessment Procedure (SAP) for energy rating of dwellings. The test data from
which it has been calculated have been certied by a notied body.
