37、 Scope This standard defines, for the purpose of type examination, the construction, the safety characteristics, the test methods and the marking of mobile and portable non-domestic forced convection direct fired air heaters with a rated heat input not exceeding 180 kW (H s ) and burning third famil
38、y gases, referred to in the body of the text as “appliances”. This standard covers the following type of mobile and portable non-domestic forced convection direct fired air heaters of type A 3(see CR 1749) fitted with an integral burner intended for use in other than residential dwellings: a) low ga
39、s pressure appliances operating at pressures up to and including 50 mbar burning commercial butane and/or commercial propane; b) medium gas pressure appliances operating at pressures above 50 mbar and up to !2 bar“ burning commercial butane and/or commercial propane. It does not apply to appliances
40、which are intended to be fixed or permanently installed, or to appliances which incorporate liquid feed burners. Requirements for appliances given in this standard assume that the supply of gas from the gas cylinder will be governed by a pressure regulator. These appliances are not equipped with an
41、appliance governor. !Text deleted.“ This standard does not cover cylinders for liquefied petroleum gases or their associated regulators. There are no specific thermal efficiency requirements appropriate to these types of appliances as: a) all the heat produced by the combustion process is released i
42、nto the space to be heated; b) the requirements with regard to the combustion performance, which is a safety matter, ensure the effective burning of the fuel gas. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications.
