Key to symbols
GB = United Kingdom IE = Ireland (Countries of destination)
PMS = Maximum operating pressure of water
B
11BS
= An appliance designed for connection to a flue discharging the products
of combustion outside the room, with air for combustion being drawn
directly from the room where the appliance is installed, without a fan
in the combustion products circuit and fitted with a combustion products
discharge safety device.
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
).
*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 BGplc 0087
