Course Duration - 5 Days

The Gas Appliance Maintenance & Repair course is designed for technicians who want to develop a structured approach to diagnosing, servicing and repairing a wide range of gas appliances and associated control systems.

The programme combines gas-appliance fundamentals with electrical safety, testing methods, component diagnosis and fault-finding techniques. Learners develop an understanding of how gas appliances operate, how faults present themselves, and how to identify the underlying cause of performance, combustion, control or component-related problems.

The course covers appliances used in domestic, commercial and selected industrial environments and places strong emphasis on safe testing, logical diagnosis and correct repair practices.

This programme is suitable for:

• gas technicians and service personnel

• appliance repair technicians

• maintenance technicians

• LPG installers wanting to expand their appliance-repair knowledge

• commercial kitchen maintenance personnel

• facilities and technical staff responsible for gas appliances

• technicians working with electrically controlled gas equipment

• experienced tradespeople wanting to develop structured fault-finding skills

A basic understanding of gas systems and safe technical working practices is beneficial.

The programme develops knowledge and practical understanding in areas including:

• the operating principles of common gas appliances

• differences between domestic, commercial and industrial equipment

• appliance safety, ventilation and combustion requirements

• selecting and safely using diagnostic tools and test equipment

• electrical safety and safe isolation procedures

• using multimeters, manometers, leak-detection equipment and other diagnostic instruments

• reading manufacturer instructions, electrical diagrams and schematics

• understanding appliance operating sequences

• pressure, flow and combustion principles

• identifying and testing gas valves, regulators and ignition systems

• diagnosing thermostats, sensors, pressure switches and safety controls

• testing burners, flame-detection systems and combustion components

• identifying ventilation, flue and air-supply problems

• diagnosing electrical and electronic control faults

• interpreting error codes and manufacturer fault information

• using fault-finding flow charts and structured diagnostic processes

• checking gas, water, air and electrical supplies before condemning components

• identifying irregular burner and flame conditions

• testing and replacing defective components

• documenting faults, repairs and work performed

The course also exposes learners to the operating characteristics of a broad range of appliances, including cooking equipment, water heaters, fireplaces, boilers, commercial catering appliances, heaters and other gas-fired equipment.

The course can be delivered in person or online.

In-person training allows for additional practical demonstrations, use of diagnostic equipment, component testing and instructor-led fault-finding exercises.

Online delivery focuses on technical theory, diagnostic methodology, component operation, electrical and gas testing principles, manufacturer documentation, fault scenarios and structured problem-solving.

Training may include:

• instructor-led presentations

• component demonstrations

• appliance schematics and electrical diagrams

• diagnostic exercises

• fault-finding scenarios

• manufacturer manuals and technical information

• worked examples

• testing procedures

• analysis of common appliance failures

• case studies involving real-world service problems

The emphasis is on teaching technicians to follow a logical diagnostic process rather than replacing components through trial and error.

Learners may be assessed on their understanding of appliance operation, testing procedures, component function and fault-finding methodology.

Assessment may include:

• technical knowledge

• interpretation of appliance operating sequences

• identification of components and their functions

• electrical and gas-testing principles

• analysis of fault scenarios

• diagnosis of likely appliance failures

• interpretation of manufacturer information and technical diagrams

Where practical assessment forms part of the programme, learners may also be required to demonstrate the safe use of diagnostic equipment and appropriate fault-finding procedures.

Successful learners receive the applicable Gas Uni course certification confirming completion of the training and assessment requirements.

The programme can be adapted for businesses, maintenance teams, service companies and technical organisations that need to strengthen their gas-appliance diagnostic and repair capability.

Training can be tailored around:

• particular appliance types

• equipment commonly used by the organisation

• commercial kitchen equipment

• water-heating systems

• heating equipment

• recurring technical problems

• electrical and control-system diagnosis

• staff experience levels

• manufacturer-specific equipment where appropriate

Group training can be delivered online or in person depending on the technical content and practical requirements.
