Flueboost 800 Inline Chimney Fan (Boilers <234kW)

Flueboost 800 Inline Chimney Fan (Boilers <234kW) It will handle flue gases at up to 300 Deg C and boilers with heat outputs up to 800,000 Btu/h; 235 Kw. (Normally secondary flue temperatures of the average gas appliance working at 75% efficiency are 180 deg with CO2 content of 5%). The motor is a speed controllable unit with class F windings. The bearings are maintenance free sealed ball bearings with adequate lubrication to ensure reliable operation for many years. A plug-in electrical connector is supplied, this is a multi- pin connector fitted with a five core lead, the five cores are colour coded. Brown - permanent live; Blue - permanent neutral; Green & Yellow - earth; Black & White - switch live from thermostat to fan; Black - switch live from fan to boiler. NOTE:- The output supply is 220/240 volt switch live only. The pressure switch has contacts which close with air flow and open in the case of a fan failure. NOTE:- The pressure switch has an interlock installed which ensures failsafe operation. The fan has built in pre purge & post purge periods (time delay). This is to purge the boiler of any gases before and after the boiler filing sequence. All surfaces in contact with the flue gases are corrosion resistant stainless steel.
