Scope

This European Standard specifies the requirements and test methods for the safety of non-domestic direct
gas-fired forced convection air heaters having fully automatic control systems, hereafter referred to as
"appliances".
This European Standard applies to appliances of Type A2 and Type A3 with heat input based on the net
calorific value of 300 kW or less fitted with integral burners intended for use other than in residential dwellings.
It also applies to appliances designed for outdoor installation. For indoor appliances provision of the heated air
may be by means of ducting or may be directly into the heated space.
This standard does not apply to:
a) appliances intended for use in residential dwellings;
b) portable or transportable forced convection appliances;
c) appliances fitted with gas boosters;
d) appliances fitted with air/gas ratio controls;
e) appliances which incorporate a main burner having more than one section under a common burner
control, of which one or more sections may be extinguished whilst another section remains in operation.
This European Standard is applicable to appliances which are intended to be type tested.
NOTE Requirements for appliances which are not type tested would need to be subject to further consideration.
