Thank you for choosing BoilermagXT, please follow the instructions carefully to ensure that
this BoilermagXT magnetic filtration system is fitted and maintained correctly.
By completing and returning the guarantee card in the pack you qualify for a 10 year
warranty against manufacturing defects. Failure to follow these instructions will invalidate
the warranty.
BoilermagXT is a magnetic filtration system for heating systems in larger
premises such as industrial, commercial and municipal buildings. For other
applications always consult the manufacturer before installing.
This product contains strong magnets. Care and attention should be taken at all
times during installation and servicing. Do not place the magnetic cores on any
ferrous surfaces or near ferrous objects.
Suitable personal protective equipment should be used during all installation and
servicing.
BoilermagXT must be installed by a qualified person in accordance with all
relevant current regulations.

BoilermagXT is typically installed on the return circuit as close to the boiler as possible.
On larger systems, such as the one shown, smaller BoilermagXT units may be installed
elsewhere to give extra protection for radiators and pipework.
Please also ensure that the BoilermagXT is located in a position which gives adequate
access above to lift out the magnets during servicing and maintenance. Also access is
required to the underneath of the unit to connect a hose or hold a bucket during draining.
Venting Options
The BoilermagXT unit is fitted with a manual vent, however, an additional Automatic Air Vent
has been packaged along with unit separately. The auto-vent will automatically release the
trapped air maintaining heating efficiency.
Please note: If using the Automatic Air Vent, operating pressure is reduced to 10 bar and
maximum temperature to 110˚C respectively.
Please find enclosed the installation instructions for the Automatic Air Vent.
Ensure the heating system is isolated prior to carrying out
installation or maintenance work.

1. Identify a suitable location (see ‘Where to
Install’ p3).
2. Ensure enough clearance to carry out
cleaning as the rods must be lifted out of the
unit to clean. See dimensions in column B in
the table below.
3. Mark and then cut out the correct length of
pipe section to be removed to accommodate
the BoilermagXT unit and isolation valves.
Ensure the cut is level and burr free.
(Isolation valves are not included in the
BoilermagXT pack.)
4. Install appropriate isolation valves to the
pipework and fit the valves to the two PN16
flanges (see below for flange dimensions).
5. Position the BoilermagXT in place then align
and secure the fittings to connect the unit
to the valves.
6. Open the isolation valves and turn on the
heating system
7. Complete the BoilermagXT warranty card and
return to Spear & Jackson.
8. Run the heating system at normal operating
temperature and check installation integrity.

Cleaning and servicing must only be carried out by a qualified person in accordance with
all relevant current regulations.
To maintain optimum efficiency we recommend cleaning annually. However when a
BoilermagXT is fitted to an existing heating system we recommend more regular checks as it
is likely there will be a large build-up of ferrous oxide (black sludge) to clear out.
To service and maintain BoilermagXT follow the instructions below:
Lift out the magnetic cores using the handle on top
of the unit. *Warning see below*. Be careful not to
place the cores on or near ferrous items.
For 8",10" and 12" BMXT units, the weight may exceed safe single person lifting limits.
Please check and if required do as 2 persons or alternatively as a mechanical lift.
Either place a bucket underneath or connect a
hose to the 1¼" drain valve on the underside of
the BoilermagXT. Remove the drain plug and open
the drain valve. Partially open the inlet isolation
valve and allow the contents to drain through
the drain valve.
Isolate the heating system and close the isolation
valves on either side of the BoilermagXT unit.
Remove the black tricone positioned on the lid.

Servicing & Maintenance Instructions
If required open the vent shown on the top of the
unit to release any trapped air*.
When the draining water runs clear turn off the inlet
isolation valve and allow the remaining contents to
drain. Close the drain valve and replace the plug.
