▶ Align burner combustion head into appliance housing tube flange,
ensure that the burner is level.
▶ Push the burner forward into the flange ensuring that the seal is
properly seated.
▶ Secure with retaining nut.
▶ Tighten retaining nut sufficiently to ensure a good seal.
▶ Connect the burner lead into the control box socket.
▶ Attach air duct [1] and tighten hose clip [2] to secure to the burner

Electrical
Access to 230V connections:
1. Pull the control knob [D] forwards to remove from control panel [C].
2. Release screws [B] and remove cover panel [C] from control box [A].
3. Release screw [E] from cable clamp [F].
▶ Pull inner clamp part [G] outwards.
▶ Feed sufficient power cable [H] through the cable clamp [F] and
secure grip with screw [E].
▶ Separate wires from cable end and strip to 6mm.
230V connections:
4. Connect SWITCHED LIVE wire (Brown or RED) to terminal L.
▶ Connect NEUTRAL wire (Blue or Black) to terminal N.
▶ Connect EARTH wire (Green/Yellow) to the terminal
.
5. Secure the cable to the cable clamp [J].
Route the power cable to the external connection point avoiding any
potentially hot surfaces.
Refit electric control panel cover:
▶ Refit cover panel [C] to control box [A] and secure with screws [B].
▶ Refit control knob [D].
WARNING:
Flue gas leakage
The seal between the burner and the mounting flange
must form a gas tight seal to prevent leakage of
potentially dangerous gas from the combustion
chamber.
▶ Unless the burner is level when pushing the burner
into the flange the O-ring may not seat properly
allowing flue gas to escape!
▶ Always check that the O-ring seal is in good condition
before fitting the burner.
Replace the O-ring seal if defective.

DANGER:
ISOLATE THE 230V ELECTRICITY SUPPLY
▶ Ensure that the electricity supply is safely Isolated
and secured to prevent inadvertent re-connection.
Information on safe isolation can be found in the
Health and Safety Executive guidance HSG85. Using
the test equipment approved to GS38 confirm that
the electricity supply is disconnected.
▶ The mains electrical supply to the appliance and
system wiring centre must be common and through
either a common fused double pole isolator or a
fused three pin plug and unswitched socket.
▶ The isolator shall be sited next to the appliance for
new systems and where practicable, replacement
appliances.
▶ The isolator must have a contact separation of 3mm
minimum between the poles.
▶ Any additional components that are connected to the
appliance with mains electrical supply must not have
a separate supply.
▶ External fuse 5 Amps.
▶ When stripping wires ensure that copper strands do
not fall into the control box.
NOTICE:
Any external device connected to the
appliance must take its power supply from the appliance
only and must NOT have a separate supply.
See the following pages of electrical diagrams for details
of different systems.
