- Installation of Gas Pipe work and Fittings
- Can compression fittings be used in inaccessible locations?
- Pipework installed on a brick and block wall behind a dot and dab plasterboard, how would you protect the void between the plasterboard and brick and block from a potential gas escape?
- What materials can be used when sleeving gas pipework and what should also be considered when choosing the selected material?
- When running pipework within a protected shaft, what materials can be used?
- If the pipework within the protected shaft is boxed in what now should be considered?
- How far away should a gas pipe be positioned from an electricity cable?
- Operative Assessment
- SCENARIO, when carrying out a gas carcass in copper tube that is to be laid in a screeded floor, please explain the installation and testing procedures.
- Read the provided technical drawing showing gas pipe routes and sizes
- Sleeve the gas pipe through the cavity
- Test the pipework before protection is applied
- Carry out tightness test with air
- No permissible drop is allowed
- Record the test results on a test certificate
- Cap all open ends with an appropriate fitting
- SCENARIO, A new plot has already been filled with the electricity on and the gas meter connected but capped off.
- First action is to Walk the job
- Visual checks of the boiler,flue and any other gas appliances
- Check any other Gas points
- Visual check of the gas meter box, sleeving, Earth Bonding etc,
- The gas meter is capped, please describe how you would re connect the meter?
- Describe a let by test
- 7-10mb for 1 min
- If a let by occurs what would be at fault?
- Who would you contact if an ECV was letting by?
- Describe a Tightness test
- 1 min stabilisation at 20 mb, raised back to 20 mb if any drop occurs
- 2 min test at 20 mb
- If a tightness test failed on a new system what would be the permissible drop?
- Describe a purging procedure
- Ventilate the property
- No naked flames, do not operate electrical switches
- Warn others within the property that purging is taking place
- Can we purge a domestic gas installation that exceeds 0.035 of pipework and fittings volume?
- Fire Boiler
- Working pressure
- Does the engineer under stand that the working meter gas pressure should be + or - 2mb of the the set regulator pressure?
- Does the engineer understand that with the system working at maximum rate, that between the meter and each appliance there should be no greater than a 1 mb drop ?
- Explain how to gas rate an appliance
- Run appliance at its maximum, Take 1st meter reading, time for two mins, take second reading, take one from the other multiply by 30 then times 10.72 which will give you the rated KW input of that appliance. This figure should be within + or - 5% of stated manufactures data.
- Flue Gas analysis
- Visual inspection of work,
- Add media
- Standard of work/Faults
