The Flueboost 800 Boiler model will handle flue gases at up to 300°C and boilers with heat outputs up to 800,000 Btu/h; 235Kw/h, dependant on size and length of flue. (Normal secondary flue temperatures of the average gas appliance working at 75% efficiency are 180°C with a CO² at 5%).
The motor is variable speed and has an centrifugal rotor with secondary cooling impeller, Class F windings and maintenance free sealed ball bearings with adequate lubrication to ensure reliable operation for many years.
The pressure switch has contacts which close with airflow and open if flue becomes blocked or fan failure.
Installation and Maintenance
Full instructions on installation and operating come with the unit. If service or repairs are required the working parts can be removed as a sub assembly without disturbing the main case.
A plug-in electrical connector is supplied. This is multi-pin fitted with a five core colour coded lead: Brown-permanent live; Blue-permanent neutral; Green and Yellow-earth; White-switch live from thermostat to fan (dashed line in diagram); Black-switched live from fan to boiler.
The fan has variable pre-purge and post-purge periods of approx 30 sec to 3 minutes. This is to purge the appliance of any gases before ignition and after the boiler shuts down. Gas fire models have no pre or post-purge.
The unit is constructed from mill finish grade 304 stainless steel.
This appliance must have a draught diverter or draught stabiliser fitted within the primary flue section.
