1. General Information
These operating instructions explain the main functions and operation of the pump
when installed and ready for use. The installation must be completed by a qualified
engineer in accordance with BS 7593:2019
2. Application
Boiler-m8 B-Rated circulation pumps are designed for the circulation of water in
heating systems that are installed, commissioned and operated to
BS 7593:2019.
This product is suitable for domestic:
• Underfloor heating systems
• One-pipe systems
• Two-pipe systems
The Boiler-m8 RS25-6J universal central heating pump head has been designed
to be the ideal replacement head for the popular Grundfos UPS 15-50 15-60 pump,
replacing an end-of-life head only rather than having to replace the whole pump body.
This model has a 6 metre head so can easily accommodate the majority of larger
domestic systems, and incorporates a 3 speed selector giving 3m, 5m & 6m options.
The Boiler-m8 Universal Pump Head fits a standard Grundfos UPS pump base,
allowing easy replacement of the pump head without having to remove the base,
perfect for awkward or tight installations.

2.1 Advantages of installing a Boiler-m8 B-Rated Universal
Replacement Pump Head
3. Pump Liquid
Boiler-m8 circulating pumps are designed for heating system liquid treated in
compliance with BS 7593:2019
Using the pump to circulate mineral oils, fibrous fluids with particles, or aggressive/
explosive liquids will invalidate the product warranty and may cause serious injury.
Easy Installation & Quick Commissioning
• Boiler-m8 Universal Pump Head is easy to fit to a UPS base. Take care to
isolate any electrical supply before removing the four bolts holding the
end-of-life head in position, and refit the Boiler-m8 replacement, before
reconnecting the electrical supply and commissioning in compliance with
BS7593:2019.
High Degree of Comfort
• Minimum noise from valves and pipework
