High output stainless steel premix gas fired condensing boilers

Product Features

Ultra high efficiency, fully condensing with ultra low emissions
The heat output is fully variable between 25% to 100%. This ensures the boiler output automatically matches the system demand, with optimum efficiencies of 100% nett being returned. With the use of a 100% Pre-mixed combustion process, flue emissions are kept very low at:
< 53 mg/kWh – NOx (30 ppm DAF)
< 19 mg/kWh – CO (15 ppm DAF)

Direct-on-boiler weather compensation
If required, the boiler can operate to give automatic weather variable flow temperature. This ensures optimum operating efficiencies by varying the flow temperature relative to the external weather conditions.

Comprehensive control panel (optional)
The boiler control panel includes user friendly controls, which manages the entire safety functions of the appliance, simple menu driven programming via a large LCD display, frost and summer standstill protection, and more.

Room sealed flue
As a special order, the Rendamax 3600 boilers covered in this brochure can be supplied to operate as a room sealed appliance, taking air for combustion (connection F1) directly from outside the building. The case of the boiler is under negative pressure giving adding safety.

Stainless Steel Heat Exchanger
The Rendamax 3600 range of boilers utilises a well proven Stainless Steel Heat Exchanger which is connected in sectional form, and has a water cooled Stainless Steel tubular burner.

Optional matched controls for optimum efficiency
A versatile range of matched controls are available to work in conjunction with the boilers and can provide not only room temperature control, but also independent heating and hot water time control with individual day programming.

Safety valve
The Rendamax 3600 range of boilers detailed in this brochure all come supplied with 3 Bar Safety Valve factory fitted as Standard.

The Stainless Steel heat exchanger carries a 5 year guarantee, all other components carry a 12 month guarantee against manufacturing or material defects.
