Multiple Appliances Installed in the Same Room or Space
Where multiple Strata 1 boilers are installed in the same room or space then
the aggregate of the appliance inputs must be taken to determine (from the
following data) the amount of ventilation required.
Appliance gross heat inputs should be taken as:-
Strata 1/45
= 50.34 kW
Strata 1/60
= 60.20 kW
Strata 1/75
= 81.41 kW
