Introduction
These heaters are pri arily intended for installation directly onto a wall at low level. They
ust not be installed in bathroo s or other high hu idity areas. Please contact us on
01245 324900 for details of products suitable for these applications.
The ini u reco ended installation height fro the floor to the underside of the
heater is 100 . The axi u reco ended installation height fro the floor to the
underside of the heater is 500 .
A ini u clearance of 75 is required either side of the heater (except Staccato
odels) to allow for the insertion or re oval of the outer case fixing screws. No side
clearance is required for Staccato odels.
These heaters are designed for use on standard two-pipe pu ped central heating syste s
with a axi u water te perature of 86°C and a axi u pressure of 6 bar (88lbs/in2).
Pipes are 15 or 22 depending on odel and either pipe ay be used as flow or
return.
These heaters are classified as a fixed appliance and electrical connection should be via a
3A-fused spur. The fused spur ust not be directly above the heater but should be
accessible after co pletion of the installation. All heaters ust be earthed.
We reco end the use of full-flow isolating valves. The valves should be accessible after
co pletion of the installation.
To avoid the possibility of vibration these units ust be fitted on a flat even surface.
These heaters are fitted with and controlled by an integral roo ther ostat. This confor s
to Building Regulations Part L (Part J in Scotland). For further details please contact our
Technical Support on 01245 324560.
Please note the guarantee may be invalidated if this product is not installed and used in
accordance with these instructions.
Installation Guide
1. Release the outer casing by re oving the screws on either side of the casing. For
Staccato odels the screws are accessed through the front of the chassis.

3
2. Secure the ounting bracket to the wall
using fixings suitable for the wall type. Ensure
the bracket is level and flat to the wall. If
necessary use packing to co pensate for an
uneven wall surface. Mini u reco ended
installation height is 100 to the underside
of the heater. Maxi u reco ended
installation height is 500 to the underside
of the heater. Hang the heater on the
ounting bracket. Locate all four fixing holes;
two top and two botto on either side of unit.
Mark the wall through the holes and re ove
unit fro bracket. Drill a suitable sized hole
through each ark. Hang the heater onto
the bracket and secure with fixings suitable for
the wall.
Signature & Sovereign Models
It will be necessary to re ove the bleed screw cover-plate
situated at the top left hand side of the unit above the
supply pipe work. This will enable you to access the top
left fixing hole and at a later stage vent the air fro the
unit.
Sentry & Sentinel Models
The ounting bracket does not fit central to the unit. The
ounting bracket should be fixed 20 to the right of the
centre of the unit.
3. Connect the heating syste flow and return
pipes to the heater pipe work. Do not use
soldered fittings to the heater pipe work as the
heat generated could da age internal wiring and
co ponents. We reco end the use of full flow
service valves.
The valves should be accessible after co pletion of the
installation. Check for water leaks. Re ove any
trapped air fro the unit via the built in bleed screw
located on the top of the internal supply pipe work.
Signature & Sovereign Models
Refit the cover plate above the bleed screw

4. Isolate the electrical supply and connect the
heater electric cable to the fused spur (3 a p).
The fused spur ust not be directly above the
heater and ust be accessible after the
installation is co plete.
Commissioning
1. Turn on the electrical supply at the fused spur
2. Turn the ther ostat control to axi u . For Signature & Sovereign odels the heater
controls are behind the access panel on the right hand side of the heater.
3. Set the controls to Air Circulation setting – see User Guide.
4. Turn on the central heating syste
5. Set the controls to Heating – see User Guide.
6. Balance the central heating syste if these heaters are installed on the sa e circuit as
panel radiators
7. If the installation is working correctly re e ber to reset the ther ostat to its nor al
setting
Installation Continued
5. Attach the earth bonding connector to the outer casing and refit the outer casing to
the chassis.
6. Please leave this Installation & User Guide with the user for future reference

Fault Finding
1. Fan does not run on any switch setting.
a. Check the power supply is switched ON.
b. Check fuse in the fused spur.
c. Check the wiring connections at the fused spur.
2. No heat output.
a. Vent any trapped air fro the syste (with the syste turned OFF).
b. Check the central heating is switched ON.
c. Ensure the ther ostat is calling for heat.
d. Balance the central heating syste if installed on the sa e circuit as panel
radiators and increase the circulating pu p speed if required.
e. Increase the boiler water te perature.
In the event of difficulty please contact our technical help-line on 01245 324560. It will be
helpful if you do not disconnect the heater fro the central heating syste .

Your fan-assisted radiator is designed to operate as part of your central heating syste in
the sa e way as a panel radiator. Providing you leave the heat output switch in either the
nor al or boost position it will switch on and off auto atically with your central heating
syste .

How a fan-assisted radiator works
Hot water fro your central heating
syste passes through the heat exchanger
transferring its heat to the alu iniu
fins. Cooler air is drawn in by the fan and
heated as it passes over the heat
exchanger before being expelled gently
back into the roo . This not only gives a
ore even te perature spread but will
heat a roo up in less than half the ti e
of a traditional steel panel radiator.
Fan-assisted radiators include an internal ther ostat that prevents the fan fro operating
until the central heating syste water passing through the heat exchanger reaches 42ºC.
This prevents cooler air being circulated at start up.
Heating - Sentry, Sentinel, Signature/Sovereign 7, 14 & 21 models – see diagram A
Ensure your central heating syste is N. Set the
ther ostat control to the desired te perature. For
reference a setting idway between 3 and 4 is
approxi ately 20°C (68°F). Ensure the fan-only switch is
FF (out). The position of the fan-only s itch may differ
dependant on the model. Set the upper heat-output switch
to I (nor al). Providing the water te perature in the
central heating syste is ore than 42ºC and the
ther ostat is calling for heat the product will switch on. If
you require a faster war up ove the heat output switch
to II (boost). Moving the heat-output switch to will turn off the product.
Air Circulation - Sentry, Sentinel, Signature/Sovereign 7, 14 & 21 models – see diagram A
Ensure you central heating is FF. Set the ther ostat to axi u (7), the heat-output
switch to I or II and push in the fan-only switch. The position of the fan-only s itch may
differ dependant on the model. The product will provide a cooling flow of air.
Heating - Signature 30 & Sovereign 30 – see diagram C
Ensure your central heating syste is N. Set the
ther ostat control to the desired te perature. For
reference a setting idway between 3 and 4 is
approxi ately 20°C (68°F). Ensure the upper fan-only
switch is set to RED. Set the lower heat-output switch to
I (nor al heat output). Providing the water te perature
in the central heating syste is ore than 42ºC and the
ther ostat is calling for heat the heater will switch on. If
you require a faster war up ove the heat output
switch to II (boost). Moving the heat output switch to
will turn off the heater.

Air Circulation - Signature 30 & Sovereign 30 – see diagram C
Ensure you central heating is FF. Set the ther ostat to axi u (7), the heat output
switch to I or II and set the fan-only switch to BLUE. The product will provide a cooling flow
of air.
Heating - Staccato
Ensure your central heating syste is
N. Set the ther ostat control to the
