Flueboost 350 Inline Chimney Fan (Boilers <102kW)

Flueboost 350 Inline Chimney Fan (Boilers <102kW) It will handle flue gases at up to 300 Deg C and boilers with heat outputs up to 350,000 Btu/h; 102Kw. (Normally secondary flue temperatures of the average gas appliance working at 75% efficiency are 180 Deg C with a 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 event of a fan failure. NOTE:- The pressure switch has an interlock installed which ensures failsafe operation. The fan has a built in variable pre purge & post purge periods (time delay) of approximately 30 seconds to 3 minutes. This is to purge the boiler of any gases before & after the boiler firing sequence. All surfaces in contact with the flue gases are corrosion resistant stainless steel. Volts 220/240 single phase Input/Output. Starting Current 0.9 Amp. Running Current 0.51 Amp.
