PMS
= Maximum operating pressure of water
C
12
= A room sealed appliance designed for connection via
ducts to a horizontal terminal, which admits fresh air to
the burner and discharges the products of combustion to
the outside through orifices which, in this case, are
concentric. The fan is down stream of the combustion
chamber.
I
2H
= An appliance designed for use on 2nd Family gas,
Group H only.
Note.
Gas consumption is calculated using a calorific value of 38.7
MJ/m
3
(1038 Btu/ft
3
) gross or 34.9 MJ/m
3
(935 Btu/ft
3
) nett. To
obtain the gas consumption at a different calorific value:-
a.
For l/s - divide the gross heat input (kW) by the gross C.V.
of the gas (MJ/m
3
)
b.
For ft
3
/h - divide the gross heat input (Btu/h) by the gross
C.V. of the gas (Btu/ft
3
)
c.
The appliance is preset at the factory to the highest
nominal rating.
*
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 certified by a notified body.
