Pass Your Gas

 

The thermostat is the device which is responsible for keeping the heat inside any appliance at the temperature you set.  A gas oven uses settings called “Regulo”. There are 9 regulo settings on a gas oven. If you look at a recipe book written for gas appliances it will say something like “ Bake for 30 minutes at regulo 6”             This video will show you how to test that this is working correctly.  This is one of your basic tasks on your assessment and you will be asked to explain how a thermostat works.  

The spillage test is completely separate from the flue flow test .  The spillage test is designed to show the engineer that the combination of  the ventilation,  the appliance, the flue is effective enough to prevent any products of combustion from entering the room in which the appliance is situated.  The test itself is carried out with the appliance in place , turned ON, and uses a smoke match NOT a smoke pellet . It may have to be carried out more than once depending on the other appliances and electrical items in the room.

There’s a lot of confusion surrounding the flue flow test. It’s mainly because people don’t really know why they are carrying it out. It is PRIMARILY a test of the “integrity of the flue”. Integrity in this case means the “structural soundness and suitability” of the flue This means that you must check the flue from the appliance all the way to the terminal for any leaks or breaks and ensure that it will remove ALL of the products of combustion The easiest way to do this is to see if it will handle a specific volume of smoke without spilling the smoke back into the room or letting it leak out of any holes or joints. The quantity of smoke is written down, in law, as 5 metres cubed of smoke. But they don’t allow you to just make that amount of smoke over whatever time you want, if they did that you could spend all day with a small bit of wood letting wisps of smoke go up the flue. No, they say that you have 30 seconds to make the smoke and that the flue must not leak while the smoke is p...

  A GOOD START IS THE MOST IMPORTANT FACTOR IN SUCCESS As you will know, you are not allowed into the assessment area prior to your assessment. As a result, and unless you’re attending your 5 year refresher at the same school that you learned at, this is the first chance you will have had to see the layout of your assessment bay. It can be very disorientating. And this is the time that the assessor is watching you the closest. Remember he (or she) hasn’t seen you before and he will be forming his first impressions of you. This first impression will last throughout your assessment. How you act in the first minute or two is VITALLY important.  I have found that the people who most often fail are those who just start “doing things” straight away. Jumping into tightness tests or flue flows. The assessors can see that they usually lack organisation and skip many fundamentals that the assessors like to see . Remember - this is a SAFETY assessment. The ONE question that the assessor ...
