Boiler Appliance Checks
There are many things a boiler service must cover. The location of the boiler must be one that allows for the correct operation of the appliance. All the fans must be in working order, and the ignition system must correctly initiate the burner. All the seals around the boiler must be verified as intact, and the gas connection point to the boiler should be free from gas leakage. All surrounding pipework and the closing plate must be checked for integrity, and the heat exchanger must be confirmed to be passing on heat to the water. All controls (including the thermostat) must be tested, and all electrics in and leading to the boiler must be verified as being operationally sound. A gas tightness test is also carried out to check for any gas leaks leading to the appliance. However, even if the test is a pass, the smell or detection of gas would mean the leak has to be traced anyway. In addition, the boiler must also be run for a while, to verify if the appliance is stable for extended periods of time.
