This European Standard specifies the additional requirements and test methods for gas-fired air heaters
which are designed so that water vapour condenses from combustion products. On this subject, it extends
the European Standards EN 778 and EN 1319 for domestic air heaters, and EN 1020 for non-domestic air
heaters.
