The Flueboost 350 Boiler model will control flue gasses up to 300c and boilers with heat outputs up to 350,000 Bth/h; 102Kw/h. Over again this varies due to size and length of flue. Based on normal secondary flue temperatures of the average gas appliance working at 75% efficiency are 180c with a C02 at 5%.
The motor is again variable speed, using a centrifugal rotor with a secondary cooling impeller. This time class F windings, again having maintenance free sealed lubricated ball bearings.
Again this is too ensure reliable operation for the duration.
The pressure switch contacts work in the same way across the Flueboost range.
Closing on air flow
Opening if flue becomes blocked or a fan failure occurs.
Each unit comes complete with: Full installation manual Full operating manual Maintenance can be done swiftly without disturbing the main body as working parts can be removed and replaced with only partial assembly. Leaving the main body of the unit untouched.
A plug in electrical connector is supplied.
It's a multi pin:
Brown permanent live
Blue permanent neutral
Green and yellow earth
White switch is live from thermostat to fan (appearing a a dashed line in manual diagram)
Black switch is live from fan to boiler
The fan has variable pre and post purge periods, approximately, 30 seconds to 3 minutes.
This is to aid purging of gasses within the appliance pre ignition. Gas fire models require no pre or post purge.
All Flueboost models are constructed of high quality stainless steel. With a finish grade of Mill 304
This appliance must have a draught diverter or draught stabiliser fitted within the primary flue section.
