17、 oil-fired air heaters using only forced draught oil burners, hereafter referred to as “appliances”. This document applies to stationary and portable appliances. It also applies to appliances intended for outdoor installation. Provision of the heated air may be by means of ducting or may be directly
18、 into the heated space. For the purpose of this document the heat generation is by the combustion of liquid fuel oils as defined in EN 267 (gas oil with a viscosity at the burner inlet of 1,6 mm/s (cSt) up to 6 mm/s (cSt) at 20 C). Alternatively, if the manufacturer requests, the fuel of kerosene ma
19、y be used as defined in EN 304. Kerosene with a viscosity at the burner of 1,3 mm 2 /s (cSt) to 2,9 mm 2 /s (cSt) at 20 C) or other suitable liquid fuel oils may also be used. This document does not apply to: appliances intended for use in a single unit residential dwelling; appliances of the conden
20、sing type; appliances with atmospheric burners without a fan to assist the transportation of combustion air; dual purpose air conditioning appliances (heating and cooling); appliances where the air is heated by an intermediate fluid; appliances fitted with manual or automatic flue dampers; appliance
21、s having multiple heating units with a single flue; appliances fitted with more than one flue outlet. This document 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. 2 Normat
