Tolley's Basic Science and Practice of Gas Service, Fourth Edition: Gas Service Technology Volume 1

This is the first of three volumes of essential reference for those concerned with the installation and servicing of domestic and industrial gas equipment. This volume explains the basic principles underlying the practical and theoretical aspects of installing and servicing gas appliances and associated equipment, from the basics of combustion, to burners, pressure and flow, transfer of heat, controls, as well as materials and processes, electrical aspects, and metering and measuring devices.

The revised fourth edition is brought fully up to date with current Standards and legislation to reflect recent developments in industry, in line with requirements of the ACS Certificates of Competence and NVQs. The book includes a new section on medium to low pressure regulators for domestic properties. Covering both Natural Gas and Liquefied Petroleum Gas, the many illustrations and worked examples included throughout the text will help the reader to understand the principles under discussion.

Volume 1 of the Gas Service Technology Series will enable the reader to put into practice the safe installation and servicing procedures described in the companion volumes: Domestic Gas Installation Practice (Volume 2), and Industrial and Commercial Gas Installation Practice (Volume 3). Combining a comprehensive reference with practical application in real-world engineering contexts, Volume 1 provides an essential handbook for all aspects of fundamental gas servicing technology, ideal for both students new to the field as well as professionals and none-operational professionals (e.g. Specifiers, Managers, Supervisors) as an ongoing source of reference.


* Comprehensive reference combined with practical application - an essential handbook for gas service technology
* Fully updated in line with the latest changes to Standards, NVQs and ACS Certificates of Competence
* Hundreds of line drawings and photographs maximise accessibility of the text, enabling readers to easily recognise the appliances under discussion

secondary "safety valve" .. this is now incorporated into the gas valve itself on newer appliances. I'm not sure if it even works (although it does make a flapping noise when I shook it) .. but it's easier to just leave it be.

The second edition of Gas Installation Technology will be of interest to all concerned with gas installation work, whether plumbers, heating engineers or dedicated gas fitters. It continues to provide a definitive text for students taking NVQ gas installation and plumbing courses, and a useful reference for operatives renewing their gas competences.
Brought fully up to date to comply with the latest regulations and best practices, it covers domestic, commercial and LPG installations, and provides essential information in a concise, readable, colourful and highly illustrated format. The new edition features enhanced diagrams and photographs to aid understanding. The second edition of Gas Installation Technology continues to be a companion to the author’s highly successful textbook, Plumbing, and together both books offer plumbers, heating engineers and gas fitters, or students of these disciplines, unrivalled coverage of their subject.
Fully revised to cover the latest legislation, best practices and current installation procedures, it covers domestic, commercial and LPG installations
Still the only textbook devoted to domestic gas, commercial gas and LPG installation
Concise and readable, heavily illustrated with colour diagrams and photographs to aid understanding and recall
