THE ADVANTAGES OF PRIME

EASY TO INSTALL

The ultra-compact dimensions 700x395x279 mm and the weight of just 26 kg reduce installation time. The new Prime has the same distance between centers of the hydraulic connections of the conventional BAXI boilers to be replaced. Front access to the electrical connection also speeds up connection times.

The fixing bracket supplied as standard and the visible hooks facilitate wall mounting.

LOWER ENERGY CONSUMPTION

Thanks to the condensing technology, the high efficiency pump and the series of modulating room thermostats available as an accessory.

The new regulation 7129-3:2015 prescribes the possibility of creating collective flues in positive pressure only for type C condensing appliances.

It is possible to connect to a collective flue in positive pressure only appliances declared suitable by the manufacturer for this application and equipped with a non-return device (clapet), designed to prevent the combustion products from flowing out through appliances connected and temporarily switched off; the smoke non-return valve is an integral part of the appliance.

THE REGULATION 7129-3:2015

Regulation 7129-3:2015 prescribes the possibility of creating collective flues in positive pressure only
for type C condensing appliances.
Only devices declared suitable can be connected to a positive pressure collective flue
by the manufacturer for this application and equipped with a non-return device (clapet), designed to prevent the products from
combustion to flow through appliances connected and momentarily switched off; the smoke non-return valve is part
component of the appliance.

• CLAPET (SMOKE NON-RETURN VALVE)

Included in the duct downstream of the air-gas group fan.

• CONNECTED TO COLLECTIVE PRESSURIZED FLUES

Thanks to the integrated flue non-return valve (clapet), Prime is designed for connection to pressurized collective flues.

SMOKE PIPES Ø50 MM

Possibility of restoring flues with Ø50 mm exhaust hose (up to 40m of exhaust)

FLEXIBILITY IN THE REPLACEMENT

Easy replacement of old standard boilers, thanks to the central flue outlet and the separate adjustable outlet supplied as standard.

The Ø 60/100 coaxial drain is available as an accessory that can be combined with a pipe extension and a 60/100 diameter 90° elbow (360° adjustable).

To facilitate replacement in installations where space is limited (flue gas outlet at the rear of the boiler), the new accessory is available with a lowered coaxial 90° bend.

NEW COMBUSTION GROUP

The Prime combines the performance of the stainless steel exchanger with the advantages of a new generation burner integrated with an innovative cold closing door.

The new cylindrical burner ensures greater thermal and acoustic comfort, and reduced NOx and CO emissions thanks to greater flame stability. The new cold door reduces losses by 75% with surface temperatures below 20°C, guaranteeing significant savings in stand-by and during operation, speeding up maintenance, as there is no need to wait
let it cool down.
