Any 'rate' necessarily includes a time component; otherwise it's not really a rate but an 'amount'.
Every appliance manufacturer's instructions I've seen uses "ft3 / h" or "m3 / h" as the unit of gas rate. This makes sense because the time component (hour) is included in the information. If it...
The fact that they're using units of volume for flow rate (missing the "per hour" bit) would make me mistrust this exam as a whole. It might be OK for practice but I wouldn't fret too much over individual questions.
As for the bathroom question, Technical Bulletin 001, situation 7.5 states that...
Meter installation is not an acceptable route to becoming a fully-qualified gas appliance engineer.
No reputable gas assessment centre (or certification body) would allow a candidate to undertake full CCN1 and appliance assessments if that candidate had only qualifications and experience in gas...
Just fielding other opinions on this new gas safety compliance scheme from Capita:
[sorry - link to installeronline article was not permitted]
I find it confusing to have a second scheme run by the same company that runs the Gas Safe Register. The time and effort could have been put into...
A gas engineer on a recent domestic renewal told me he liked wood burners because 'they don't produce'. When I asked him what he meant it turned out he thought that wood did not produce carbon monoxide when burnt.
There is no written-in-stone requirement to write up pipe sizing calculations. Many engineers use phone apps anyway. However, if you actually did calculations why not include them?
You won't be able to use an app during the assessment.
Domestic natural gas ventilation for a single appliance is pretty straightforward: if manufacturer's information is unavailable there's a simple formula for open flue appliances (which works for all open flue appliances except DFEs) and a...
One tip to remember when you're asked to do a visual inspection in ACS assessments is to really look; not just glance at things. Whether it's gas pipes or flues, look closely and in detail, not just at the front but around and behind. Take your time.
With the pipework task I would suggest...
It's worth remembering that current standards state the 7 kW allowance for non-DFE open flues shouldn't be taken for granted. Newer houses and older houses that have been draughtproofed, double glazed or insulated are more airtight than properties built when adventitious air was first...
You would still need a portfolio of CCN1-relevant work (appliance installation, servicing, breakdowns etc).
You would also need a certain amount of off-job training (classroom, workshop). This does not need to be an NVQ; there are several equivalent foundation-level certificates that will allow...
