This is the part that most people watch an engineer carry out, and think "it's not difficult" - and we agree!! Like any job, there are better ways of doing things and then there is the plain idle or poor way. Too often we get invited into service an Aga when someone has done it poorly, and simply doesn't understand how or why it works. 

For this reason we wrote the Service Instructions. 

Learn the correct way and the cash investment will pay for itself within a year!! 

No complicated or specialist tools required, just a little valuable knowledge. Our principle is simple - "Do the job properly - ONCE".
