could anybody give me some indication on what to expect on my initial ACS assesment. i am due to atttend 2 days of training and 3 days of assesments in 4 weeks time but cant get any info about what happens on it.
Just re-sat my aplliances and CCN1 in January, the training you get should prepare you for the assessments.
I re-sat CCN1, CKR1, HTR1, CEN1, WAT1, WAH1
The assessments will consist of one closed book paper, and the number of open book papers will depend on what appliances you're taking (WAT1 - water heaters, CEN1 central heating boilers <70kw etc etc) the regulations papers aren't too bad but you get sick of going back and forth through the regs looking for answers - you may also find that some of the answers on the regs aren't in the regs - your assessor should point you in the right direction.
The closed book paper is really things that you should know, what pressure to test at (tightness, letby and stabilisation) etc.
You will also undertake practical assessments, I had to install a gas fire, cooker, warm air unit, find faults on pipework, fault finding on appliances, identifying devices, in my case there were 15 on a rig set up in the center - oxy-pilot, flame rectification, governor, isolation valve, safety shut-off (cooker lid) vapour pressure, mechanical and electrical thermostats etc - You then have to match a written statement to the device. Visually inspect and identify faults on appliances and flues (eg open flue with 90 degree bends, dampers in flues, overheat stat linked out, wrong terminal etc) calculate ventilation sizes, identify appliances with signs of spillage (big black marks on case or around flue) etc, just remember they're not trying to catch you out, just make sure you're safe to be let loose on gas.
All questions are multiple choice, and you wont be failed for getting a few wrong, you get a maximum of 3 attempts per paper then you'd be referred to the examining body. Practical tests, they really want the correct answer first time.
They put faults on appliances for you to find, some are real faulted parts and some are man made faults (wirewool in gas hob burner, gives inccorrect flame picture, kinked or cut silicone hose on air presure switch etc) the overheat stat had been linked with abit of wire. To simulate a boiler with a overheat problem/faulty OH stat - where the OH stat has been linked out to stop the boiler going off.
Not meaning to un-nerve you but the initial assessments are the toughest, out of 7 candidates on the initial assessment I sat, only 2 of us passed. Basically if you pass the initial assessment after 5 years they know you're working on gas daily and are abit more understanding (about the stress of assessments) and are not as tough on you, although I have known people fail their re-assessments
i am due to sit ccn1 and cen1 in few weeks should i still study up on cookers and fires etc. even though im only sitting boilers ( cen 1 ) the reason im asking is because i dont no if there is questions on fires cookers etc in the ccn1 question papers...
