• Sealant: tri-lip 'o' type silicone ring
• Fuel type: Gas

Considerations
Airtherm can offer a fan dilution system to suit many appliances, from modern high efficiency condensing to gas blown and atmospheric boilers, however the principal of diluting the products of combustion is to reduce the CO² content at the discharge to below 1%, CO 50ppm & NOx 5ppm (BS6644 / IGEUP/10) in line with current legislation.

There are many design considerations that must be achieved, for instance, the correct sizing of the fan unit, dilution header, inlet and discharge plenum boxes, the location to adjacent buildings, openable windows, fresh air vent pipes and final discharge height. These can be found from the Clean Air Act memorandum, IGEUP/10 or BS6644, along with other certain provisions with respect to the final discharge height which is calculated based on the total kw input load of the plant.

Good Practice
There are two methods that can be considered when designing the dilution system -
• Air is directly taken from the outside.
• Fresh air is taken from within the plant area.

We offer a design, supply and installation service for flue dilution systems, and can offer a tailored-made package to site conditions and customer requirements.
