By the end of this module, you’ll understand the role of gas meters, their various forms, and safety protocols for handling them.
Lesson 3: Combustion
In this module on combustion, you’ll learn the main constituents of complete and incomplete combustion, requirements for complete combustion, and visual signs of incomplete combustion. Topics include identifying burner flame pictures, ambient levels of CO and CO2, and the combustion process. You’ll explore the properties of gases like natural gas, propane, butane, and hydrogen, understand the importance of gas and air ratios, and recognise the dangers of carbon monoxide. This knowledge ensures safe and efficient combustion in your work.
Lesson 4: Tightness Testing
In this module on tightness testing, you’ll learn its importance in daily gas engineering tasks. By the end, you’ll understand how to correctly select and read pressure gauges, the allowed pressure drops for existing installations, and how to handle different meter types, including ultrasonic, diaphragm, and no-meter situations. You’ll also cover procedures for identifying non-perceptible movement on gauges, dealing with emergency control valves letting by, and handling gas leaks. Proper testing ensures safety and accuracy in gas installations and maintenance.
Lesson 5: Purging
In this module on purging, you’ll learn when and how to purge a gas installation. You’ll understand the purge volume (PV) for installations with E6, U6, and G4 meters connected to pipework up to 28mm, and how to calculate the internal volume (IV) and PV for installations with 35mm pipework. You’ll also cover requirements for installations with internal volumes less than 0.02 cubic meters and those exceeding this volume. Purging is necessary to remove air from new or altered installations, ensuring safe gas operation.
Lesson 6: Gas Rates and Heat Inputs
In this module, we’ll cover gas rates and heat inputs. By the end, you’ll understand the importance of measuring the gas rate of an appliance, where to find the required gas rate information, and how to calculate gas rates using different types of meters. Accurate gas rate measurement ensures efficiency and proper appliance operation. We’ll demonstrate calculating gas rates for Imperial, metric, and smart meters, and how to compare these with appliance data to ensure compliance.
Lesson 7: Ventilation
In this module, we’ll cover the requirements for ventilation, adventitious air supplies, sizing of grills and vents, free area availability, and installation guidelines. You’ll learn about correct and incorrect ventilation types, calculating ventilation for various appliance types, and additional ventilation requirements in different scenarios.

Lesson 8: Chimneys and Flues Part 1
In this module, we cover the basics of chimneys and flues. You will learn about their definitions, relevant regulations, and standards. We’ll discuss the need for chimneys and flues, how they operate, and factors affecting their performance. Key topics include chimney/flue height, cross-sectional area, gas temperature, heat loss, routing, and terminal design. We’ll also touch on the construction of individual chimneys and open flues. Part two will dive deeper into open flue types and construction.
Lesson 9: Chimneys and Flues Part 2
Following on from part one, we’re now delving deeper into open flues. By the end of this module, you should understand the different types of open flues, including their materials and construction. We’ll explore the traditional brick-built chimney, pre-cast concrete blocks, and various flue pipes. Learn about the essential components such as the chimney cap, flue liner, damper, firebox, and hearth, and understand the regulations ensuring their safety and functionality.
Lesson 10: Chimneys and Flues Part 3
In this module, we delve into room-sealed appliances. By the end, you’ll understand the principles of room-sealed and balanced flue appliances, the operation of fandraft appliances, and the various flue systems and terminals for these appliances. We’ll explore the advantages of fandraft systems, the importance of proper flue installation, and the impact of terminal location on performance. Additionally, we discuss the requirements for flueing in voids, including inspection and maintenance considerations.
Lesson 11: Chimneys and Flues Part 4
Today, we continue our series on chimneys and flues with part four, focusing on gas appliance classification and their corresponding flue types. You’ll learn about the European classification system, categorizing appliances as flueless (Type A), open flued (Type B), and room-sealed/balance flue (Type C). We’ll explore subscript numbers that identify appliance designs, fan positions, and configurations for both natural and fan-assisted draft systems, and the specific applications of each type.
Lesson 12: Gas Controls Part 1
In this lesson, you’ll learn about gas controls, including gas control taps for Simplex and Duplex burners, flame supervision devices (bi-metallic, liquid vapor, and thermoelectric thermocouples), atmosphere sensing devices (ASDs or ODSs), pressure regulators, and mechanical and liquid expansion thermostats. We’ll explore their functions, applications, and safety mechanisms, providing a comprehensive understanding of their roles in gas appliances. This module is part one of a two-part series.
Lesson 13: Gas Controls Part 2
In this lesson, you’ll learn about gas controls part two, covering a range of advanced topics including electrical thermostats, solenoid gas valves, multi-functional controls, cooker safety shut-off valves, relay valves, pressure-operated control systems, flame protection systems, zero governors, premix burners with zero governors, air pressure switches, low-pressure cut-off valves, and non-return valves. By the end, you’ll understand the workings, applications, and safety mechanisms of these modern gas control devices.
Lesson 14: Gas Safety Legislation
In this lesson, you’ll learn about gas safety legislation, focusing on the Gas Safety (Installation and Use) Regulations 1998.
