How to install a Boiler Buddy
Boiler Buddy has a transparent body casing so that the build-up of contamination on the core can be observed in
service. It has been designed to be fitted where it can be inspected and removed for cleaning and should be installed
in the central heating return line as close to the boiler as possible.
There are a variety of installations but in general the open-vented system and the sealed system are typical.

Points to consider
When selecting a position to install a Boiler Buddy
■
beware of electrical connections in the vicinity, as these
will be hazardous if they come into contact with water.
Install the Boiler Buddy with both an upstream and
■
downstream servicing valve.
Boiler Buddy is designed for use with standard 1
■
x 22 mm pump servicing valves (on a 15 mm system we
recommend fitting 22 to 15 mm reducing sets instead of
three 22 mm olive in the pump servicing valves).
Boiler Buddy has a face-to-face dimension of 130 mm.
■
If standard pump servicing valves are used, a total
■
space of 250 mm is required for installation.
During installation ensure that all copper or plastic swarf
■
After installation
The Boiler Buddy has no moving parts and needs no
■
adjustment once in service.
The body casing is transparent so that build-up of
■
contamination can be observed.
It is normal for the magnet nearest the inlet of the
■
Boiler Buddy to become full first. Once this is full the
next magnet will clog up followed by the next and so
on. The Boiler Buddy has six magnets, we recommend
cleaning the core when three magnets become full.

is removed from joints and does not enter the water
pipework. If soldered joints are being used to construct
the pipework, ensure solder or flux is wiped away to
avoid corroding plastic parts. Do NOT undertake any
soldering while the Boiler Buddy is in the pipework.
Boiler Buddy MUST be removed before soldering
any joints.
Once installed, secure the tamper-proof tag to avoid
accidental opening. The tag must be replaced after
cleaning the core.
Complete the Boiler Buddy installation sticker and apply
to the boiler.
Run the system and check for leaks.
It is recommended the Boiler Buddy is inspected and
cleaned annually.
Boiler Buddy is designed to last the life of the central
heating system. More frequent cleaning of the core is an
indication that the system has not been treated correctly
with Fernox Protectors, Restorers and cleansers.
