Ever wondered what the most common questions we receive are? Well, we’ve asked our customer service teams exactly that. In the first of a two-part series, we provide the answers.
For a gas engineer, no two workdays are ever the same as they carry out lots of complex tasks on a daily basis. So, we asked our customer service teams for the most common questions asked. Graham Collins, Training Support Manager at Baxi Heating explains the answers to these below:
Flue siting is a common concern as incorrect siting can become a nuisance for neighbours. For example, installing the terminal across a neighbouring driveway or placing pluming above the pavement could result in the exiting condensate cloud disturbing nearby residents.
In fact, this type of flue siting falls short of standard practice. As a general rule, BS5440 Part 1 should always be consulted on the minimum clearance for flue terminal siting. When the flue cannot be re-sited, there are plenty of other options available, such as displacement kits and plume detectors, to ensure nuisance pluming does not occur.
Knowing how to diagnose and resolve the problem that cause error codes quickly is vital. This is where online tools can help. For Baxi this comes in the form of the Toolbelt app, whereby installers can simply input the brand, range and boiler type into the app, and the error code and a pop-up will provide an explanation of the fault.
For boilers with a coiled stainless-steel heat exchanger, it is important that the exchanger is de-aerated before carrying out any work. A boiler system’s efficiency will naturally decline over time due to the metallic particles and oxygen in the air circulating through it. These will react and form oxides, such as magnetite or sludge, that can build up and affect system performance.
As a result, it is vital oxygen is removed from the system before carrying out installation work.
To do so, the boiler must be entered into the deaeration function where the pump will run but the boiler will not fire, clearing contaminated air from the system in a process that should take a few minutes. The process is relatively simply and installers can refer to the manufacturer’s guidelines for further information or click here to watch a simple guide on the Baxi 600 model.
