Condensate Drainage

OPTION: Condensate soak away kit including lime stone chippings (Pt.no. RP024)

RECOMMENDATION: Seal condensate pipe work with Rectorseal Tru-blu, a non-setting sealant that doesn’t that doesn’t dry out like glue and remains easy to dismantle, it’s also suitable for oil line connections.

Fuel Supply

IMPORTANT: Tuscan boilers utilise a single pipe suction lift fuel supply system; it’s essential to keep the number of joints between the oil tank and the burner to a minimum, use pipe benders rather than fittings.

Note: One of the advantages of the ELCO and pump configuration we use is that unlike a Riello burner where sometimes a deaerator like a Tigerloop is essential they are absolutey not required with a Tuscan Boiler; they will of course act as a ‘mask’ faults with the fuel supply system, acting as a ‘plaster’, better to resolve the problem; deaerator’s have their own inherent problems.

Regulations

IMPORTANT: Boiler installation must comply with Building Regulations, associated E.N./ British Standards and industry good practice. Installation of a megnetic system filter forms part of this compliance.
