Aimed squarely at gas installers who are preparing for domestic ACS assessment/re-assessment or who just want to brush up on their knowledge and students studying domestic gas installations, the NEW Training Workbooks provide questions and answers in a similar fashion to what will be encountered under assessment conditions.

The appliance Workbook entitled Domestic Gas-Fired Appliances (CENWAT, HTR1 & CKR1)' – Code: TWB1 – deals with four of the most popular domestic gas-fired appliances; water boilers, water heaters, gas fires & space heaters, and gas cookers.

The Workbook, which partners the core Workbook (Code: TWB0) deals with the fundamental aspects of any domestic gas-fired appliance and uses other CORGIdirect publications as the reference source - this approach means that customer's who are already in possession of our up-to-date manuals will save money by only needing to purchase two training workbooks.

The Workbooks have been authored by a time-served gas installer and current ACS assessor to ensure they meet the needs of our customers' as well as their applicability to the given subject area.

TWB1 uses the following publications as the reference source to the questions posed: • Essential Gas Safety – Domestic (6th Edition) Code: GID1 Note: Current version of Essential Gas Safety – Domestic is the 7th Edition, which was updated after this publication. The 6th Edition remains relevant for those customers already possessing this manual. • The Gas Industry Unsafe Situations Procedure 6th Edition Code: USP1 • Central Heating Wet and Dry (4th Edition) Code: GID7 • Water Heaters (2nd Edition) – Code: GID5 • Gas Fires and Space Heaters (4th Edition) – Code: GID3 • Gas cookers and Ranges – Domestic (3rd Edition) – Code: GID2
