Introduction

The highly respected second edition of Gas Installation Technology was completed in 2010, and as with any technical work, revisions are needed in light of new thinking, industry updates, advances and innovations. This third edition builds on the fine foundation of the work completed by Roy Treloar and continues to cover all areas of the gas industry that operatives are likely to encounter.

In addition to being fully updated to current standards, the layout has been revised and includes a number of additions. An appendix has been included along with a comprehensive index and section‐numbered text for ease of referencing. Commercial Catering and Commercial Laundry have been given their own dedicated parts, and there are additional parts focusing on Educational Establishments and the ACS Assessment Process. Full‐colour photographs are now displayed throughout.

The information contained within continues to purposely group together all the various aspects of gas work to include both natural gas and LPG within domestic and commercial installations. This overcomes the problem of repeating topics and allows all relevant information to be contained within one volume. There are variances to this, hence the need to sometimes identify specific installation types and procedures, and this has been done where necessary.

Although many recent industry standards and documents have adopted new style unit symbols in their specification text, we have continued to use the more familiar original notations throughout this book, as shown below and defined in the Appendix:

The book is not designed to be read from cover to cover, and the reader will invariably need to dip into it to retrieve information on a specific problem or interest. A particular topic of interest can be found in one of the following ways:

First, by referring to the contents page which identifies the subject areas of the book.

Second, by referring to the index and choosing a term related to the subject in question.

This book will be beneficial to both new entrants to the gas industry and highly experienced engineers alike. It will prove an invaluable on‐site guide for all gas engineers, and we hope that it will also prove useful during training and in preparation for your ACS assessments.

It should be noted that Building Regulations differ depending on where you are working in the United Kingdom. As it has not been possible to list all regional differences, this publication primarily refers to Building Regulations (England). Therefore, operatives should ensure that they are working to the correct regulations by contacting their Local Authority Building Control.

With the completion of this revised edition, it is our sincere hope and expectation that Gas Installation Technology will continue to be widely used and respected by all sectors of the gas industry.

1The Gas Industry

The Gas Industry

1.1 The gas industry has gone through major changes in the past few decades. Prior to, and during, the early 1960s most gas installation work in the UK was undertaken by British Gas. In 1968, a 22‐storey block of flats in Canning Town, East London, was devastated by a major gas explosion, which persuaded the industry that a body was needed to oversee this kind of work. As a result, in 1970 a voluntary gas body was formed, called the Confederation of Registered Gas Installers (CORGI).

During the early 1970s, plumbers and heating engineers began to take a greater interest in undertaking gas work, thanks to central heating systems becoming a requirement in the average home. In 1972 the first Gas Safety Regulations were introduced, which identified the legal responsibilities to which the installer had to adhere.

With the introduction of the Approved Code of Practice (ACOP) in 1990, gas installers started to take updated training and assessments in gas working practices. By 1991, anyone working in the gas industry for financial gain had to be registered with a Health and Safety Executive (HSE) approved body.

From 1991 through to 2009 CORGI (renamed the Council for Registered Gas Installers) held the register, which all gas engineers needed to be a member of. On 1 April 2009, under an agreement with the HSE, the Gas Safe Register was launched and replaced CORGI as the only gas safety registration body in Great Britain and Northern Ireland. The Gas Safe Register also operates in the Isle of Man, Jersey and Guernsey and works on behalf of the relevant Health and Safety Authorities in those regions.

Since 1991 all gas engineers have needed to be assessed as competent in the aspect of gas work that they wish to undertake; undertaking any work without this assessment would mean that they are in breach of the law and working illegally. The assessment that an individual undertakes is called the Nationally Accredited Certification Scheme for Individual Gas Fitting Operatives (ACS). There are many different assessments, and these are listed in Section 1.5.

Working in the Gas Industry

1.2 Today, if you wish to work in the gas industry, you must belong to a Gas Safe registered company or become registered in your own right. Becoming registered is no easy task, and currently there are really only two options available:

Option 1

Gain a qualification such as a Level 3 Diploma in Gas Engineering or a Level 3 Plumbing and Domestic Heating diploma with a gas pathway.

These qualifications are usually linked to an apprenticeship and are vocational, meaning employment with a Gas Safe registered company is necessary. These qualifications require the completion of in‐centre and work‐based training. This provides the knowledge, skills and experience individuals need to apply for Gas Safe registration after completion of the knowledge and practical assessments associated with the course. In addition, you will also be required to build an ‘on the job’ portfolio of work‐based evidence whilst working under the direct supervision of a registered gas engineer. Only after you have successfully completed your qualification can you apply for Gas Safe registration.

Option 2

Enrol in an industry‐recognised training programme that meets the requirements of IGEM/IG/1 ‘Standards of training in gas work’.

This standard, first published on 1 April 2014 by the Institution of Gas Engineers and Managers (IGEM), provides the agreed scope and structure of training for new entrants to the gas industry and will enable you to gain experience in the areas of gas work that you wish to undertake. The course will be an extended Managed Learning Programme (MLP) and will consist of a minimum number of classroom‐based guided learning hours.

You will also need to complete a minimum number of hours ‘on the job’ training whilst working under the direct supervision of a Gas Safe registered engineer who is willing to sponsor and train you, acting as your mentor. During this period, you will need to complete a portfolio with authenticated evidence of installations that you have completed, demonstrating the relevant knowledge, skills and experience you have gained whilst working under the guidance of the registered installer.

You will then complete a range of theoretical and practical assessments at the training centre to prove your knowledge, skills and understanding of matters relating to gas safety. Upon successful completion of both on and off‐site requirements, you will be issued with a certificate of training.
