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
11/2" BSP x 22 mm pump servicing valves (on a
15 mm system we recommend fitting 22 to 15
mm reducing sets instead of three 22mm 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 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.
How to service and clean a Boiler Buddy
Before removing the Boiler Buddy, place a container
underneath the pipework to retain any water that
may drip.
1. Isolate the Boiler Buddy from the system, by simply
closing the quarter turn valves on the pump service
connector.
2. Once the Boiler Buddy has been isolated it can be
removed. Undo the two 11/2" BSP union nuts. Once
these have been fully unscrewed the Boiler Buddy can
be pulled out between the two flat faces. The two
fibre washers may stick to the flat surface and tear on
removal of the Boiler Buddy, this is normal.

PRODUCTS
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.
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.
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.
3. Cut off the tamper-proof tag.
4. Open the latch on the body clamp and slide off the
complete clamp over one end of the body.
5. Pull the two halves apart.
