Quick and simple cascade installation

The innovative, low weight cascade design used with the GB162 series means that it is particularly installation-friendly, saving fitting time and costs.

The cascade boiler connection kit is supplied with all the necessary fittings and accessories all of which can easily be transported to a boiler room.

The installer builds the framework and constructs the pipe system in a few simple steps as shown below. After installation everything fits together perfectly, pipe work is tidy, and the boilers are connected to the main heating system, without the need to install additional hydraulic equipment.

1st step:
The sturdy floor standing cascade framework is bolted together.


2nd step:
Low-loss header, flow, return and gas pipe are fitted.


3rd step:
Individual GB162 boilers are mounted securely on the framework.


4th step:
Pump groups (additional accessory) and valves are connected to boilers and flow and return pipe work attached to the headers.


5th step:
Custom-fit insulation is added to pipework and fitted around each pump group to minimise heat loss.

Cascade features at a glance:

• Assemble freestanding, fixed to the floor
• Boilers hung directly on the frame
• Uses the GB162 pump group
• Complete unit with high quality, custom fit robust insulation
• Integrated gas pipe, flow and return with low loss header
• Up to 8 boilers with one control
• The cascade will modulate from lowest output of smallest boiler in cascade up to total load of all boilers, e.g. 20kW to 800kW for 8 x 100kW boilers and 10kW to 360kW for 8 x 45kW boilers
• Neutral flow conditions due to use of low loss header
• Best use of condensing technology due to low return temperature
