適用范圍：This British Standard specifies the installation requirements for direct andindirect gas-fired forced convection air heaters for space heating that aredesigned for commercial or industrial applications and to which The GasAppliances (Safety) Regulations 1995 [1] apply.This British Standard applies to the installation and maintenance of appliancesthat are designed to utilize gases of Group H of the 2nd family (e.g. naturalgas), gases of Group P of the 3rd family (e.g. propane) as well as gases ofGroup B of the 3rd family (e.g. butane) when supplied under the conditions ofthe third family pressure couple (see BS EN 437:2003+A1:2009). This British Standard does not specifically cover LPG/air for which additionalrequirements might be necessary.This British Standard applies to the installation of direct gas-fired air heaterswithin the scope of BS EN 525:2009 and to indirect gas-fired forced convectionair heaters within the scope of BS EN 621:2009, BS EN 1020:2009 and, whereappropriate, BS EN 1196:1998. These standards cover air heaters having a netheat input not exceeding 300 kW. This standard also applies to the installationof direct gas-fired air heaters within the scope of BS 5990:2006 and to indirectgas-fired forced convection air heaters within the scope of BS 5991:1998. Thesestandards cover air heaters having a gross heat input greater than 330 kW butnot exceeding 2 MW (1.8 MW net).NOTE 2 For the purposes of this British Standard, installation includes design,inspection and commissioning. It is recognized that each of the tasks can beperformed at the same time by different persons.NOTE 3 The ratio of gross to net heat input is approximately 1.11:1 for Group H(natural gas), 1.09:1 for Group P (propane) and 1.08:1 for Group B (butane).NOTE 4 The ventilation rates in cm2/kW of heat input given in this British Standardare based on the net calorific value.This British Standard also applies to air heaters designed to supply make-up air,door curtain heaters, transportable air heaters and heat exchange modules (i.e.air heaters without a main air movement fan) where such heat exchangemodules are used in environmental non-process applications such as air handlingunits. It also covers installation of heaters in areas where petroleum or otherflammable heavier-than-air vapours can be present (see 5.1.2).It does not include the safety requirements for installation where flammabledusts, toxic gases or flammable lighter-than-air gases might be present insignificant quantities.NOTE 5 In such cases it is important that liaison takes place with the Health andSafety Executive.This British Standard does not apply to the installation of air heaters to whichThe Gas Appliances (Safety) Regulations 1995 apply, or that are designed forthe sole use in domestic premises.
