AS NZS 5263.1.11 pdf download.Gas appliances Part 1.11: Small gas engine driven appliances
1.1.1  Scope
This Standard provides specific requirements and test methods for an appliance for fixed installation comprising a naturally aspirated gas fuelled spark ignition reciprocating internal combustion engine with energy input not exceeding 1000 MJ/h, powering one of the following: (a) Air conditioner. (b) Heat pump. (c) Electricity generator. (d) Gas compressor. For Australia, the fuel gases are natural gas (as described by AS 4564), liquefied petroleum gas (LP Gas), as described by AS 4670 and simulated natural gas (SNG). For New Zealand — (i) The fuel gases are natural gas (as specified in NZS 5442) and general product liquefied petroleum gas (NZLPG) (as specified in NZS 5435). (ii) The thermal efficiency requirements are informative only, except where they relate to safety. Appendix AA provides a figure and table referenced in this Standard that are in addition to those in AS/NZS 5263.0. Test methods are set out in Appendices ZA, ZB and ZC (see Clause 1.4). NOTE  Other statutory or regulatory requirements may be applicable to a product that falls within the scope of this Standard. It is the responsibility of the manufacturer, importer or distributor (as appropriate) to ensure that products comply with such requirements.
1.3  Terms and definitions
For the purposes of this Standard the terms and definitions given in AS/NZS 5263.0 and the following apply. 1.3.201 backfire ignition of an air/gas mixture in the flueway or exhaust system 1.3.202 engine machine that converts thermal energy from combustion of an air/gas mixture into rotary motion 1.3.203 exhaust gases flue gases 1.3.204 exhaust system passage through which exhaust gases are conveyed from an appliance flue connection to an external discharge point 1.3.205 spit back ignition of an air/gas mixture in the engine inlet manifold 1.3.206 start attempt period period from when cranking begins until the control system stops engine cranking if the engine fails to start 1.3.207 start attempt sequence of operations where an engine is cranked, the engine ignition system is turned on and the safety shut off valves are open to supply fuel gas 1.3.208 Type1 appliance appliance which is not a Type2 appliance 1.3.209 Type2 appliance appliance which dilutes exhaust gases with air prior to discharge from the exhaust flueway terminal and is classified as an emissions-controlled product under the Product Emissions Standards Rules
2.14.2  Permanent markings on appliances NOTE 1  Other marking requirements (e.g. wiring diagrams, identification of certification body and certificate number) may be applicable to a product that falls within the scope of this Standard. It is the responsibility of the manufacturer, importer or distributor (as appropriate) to check other marking requirements. Appliances shall be provided with clear and permanent markings readily accessible and easy to read. The markings shall include the information in this clause of AS/NZS 5263.0 and the following: (aa) Engine manufacturer and model. (bb) Operating ambient temperature range. (cc) Where the gas connection is not isolated from vibration a statement that the gas supply to the appliance shall be isolated from vibration. (dd) Prohibited locations for operation. NOTE 2  Prohibited locations may include under structures such as decks, outdoor areas, within 1.5 m of doors and openings into buildings and other areas where restricted ventilation may allow the accumulation of carbon monoxide from the engine exhaust. (ee) Any lifting or moving requirements. (ff) Statement indicating that a low pressure cut off device is fitted and its nominated set point. (gg) For indoor appliances, the marking: “DO NOT USE IN A HABITABLE SPACE”. (hh) For appliances that may be installed indoors, the marking: “IF INSTALLED INDOORS THIS APPLIANCE MAY AFFECT THE AIR SUPPLY OR SAFE FLUEING OF OTHER GAS APPLIANCES INSIDE THE BUILDING” NOTE 3  Air extraction systems may adversely affect the safe operation of combustion systems including those in other rooms potentially resulting in carbon monoxide poisoning.
