1 INSTALLATION
The dryer is designed for installation using a flexible gas connection with tubing in accordance with B.S. 669.
Ensure that the supply gas sizing is adequate. When installing, position the appliance so that the plug is
accessible. An electric supply cord with moulded-on 13 Amp. plug is
fitted at the back of the dryer. The length is 1.5 m. (5ft.). If there are any other appliances that are relatively high
rated (eg a central heating boiler) fed from the same gas supply branch. It is advisable to perform the verification of inlet pressure with both appliances in operation.
Prior to installation, check that the local distribution conditions, nature of gas and pressure and adjustment of the dryer are compatible.
2 AIR SUPPLY
The tumble dryer shall be installed in a room or internal space having an openable window, or equivalent. The customer must be advised that this must be kept open during use.
Purpose provided ventilation of 100cm

shall also be
provided where the room volume is less than 3.7m
3
/kw of
appliance rated heat input. Additional guidance on the provision of air supply may be
obtained from BS5440 parts 1 and 2 and BS 7624:2004 If the dryer is to be installed in a room or internal space that
already contains one or more fuel burning appliances, the ventilation requirements above, together with any additional requirements of BS5440-2:2000, 5,5 shall be applied.
3 POSITION
The dryer must not be installed in a bedroom, bathroom or shower room.
Great care is required in the location of the dryer in premises where concentrations of flammable vapours may accumulate, e.g. commercial garages and associated workshops.
The dryer can be placed against a wall, other appliances, kitchen furniture and similar surfaces.
4 VENTING
The dryer must be fitted with an exhaust vent hose and the end either hung out of a window or fitted to a wall/ window vent connection.
Note; Do not obstruct or add a mesh to the vent hose outlet during use and ensure that it cannot be blocked or bent sharply which obstruct the air flow.
It is recommended that the interior of the hose be periodically inspected and cleaned if necessary.
PERMANENT VENTING
Accessory wall/window vent kit CL005 is available: See illustration for necessary hole through wall. Dim A =
200mm and Dim B = 100mm for direct alignment. Note Dim B may be increased to 200mm to facilitate easier
drilling if required.
5 POSITION OF DRYER AND CONNECTIONS
The illustration shows the minimum space required by the dryer and the position of the gas wall connector. It is not acceptable to use a forward facing mounting plate because of the space limitation. The sideways facing assembly must be used and this should be fitted so that the flexible hose hangs down from the bayonet connector.
A 13 Amp socket must be provided within a distance of 1.4 m (55 in.) of the cable entry into the dryer. The socket must have an efficient earth connection.
If the dryer is to stand on a surface above the floor or on top of a washing machine (using the Stacking Kit) then the 750 mm dimension is measured above the supporting surface.
If the dryer is installed under a worktop there must be a minimum gap of 15 mm between the top of the dryer and the underside of the worktop to allow for ventilation.
If it is intended to move the dryer regularly for use then the Restraining Kit must be fitted to prevent possible damage to the gas connection.
We also recommend the fitting of a restraining kit to any dryer which is stacked.

6. OPERATIONAL CHECK
6.1 Remove the pressure test point screw from the gas
tee connection at the back of the dryer and connect a gas pressure gauge.
6.2 Check that the dryer timer is in the 'off' position, and
that the heat switch is set to 'high'. Remove anything from inside the drum, check that
the lint filter is fitted, shut the dryer door.
6.3 Turn on the gas, push the electric plug into the socket
and switch on the electricity supply.
6.4 Turn the timer clockwise past the dotted line marking
the cool-down period to a setting of at least 30 mins. Check for ignition. If the gas fails to remain lit then repeatedly turn the timer on and off (or open and close the door) for periods of at least 30 seconds until the air is removed from the system and burning is continuous. Note that gas is not lit when the drum is turning anti-clockwise.
6.5 With the gas burning ensure that the pressure is as
detailed in the Technical Data. Turn off and replace the pressure test point screw. Check for soundness.
6.6 Switch on again and re-start so that the gas is
burning.Disconnect the flexible gas hose and check that the solenoids can be heard to close. After 30 seconds turn on the gas and check that there is no re-ignition. Switch the machine off and on again and check for reignition.
6.7 Check that the operation of the machine does not
cause spillage of products of combustion from any open flued gas appliance in the same room, or from appliances in adjoining rooms, e.g. a gas fire or central heating boiler.
6.8 In the event of an electrical fault after installation of
the appliance, preliminary electrical system checks must be carried out (i.e. earth continuity, polarity and resistance to earth).
6.9 IMPORTANT INFORMATION RE-FUNCTIONING
OF THE FULL SEQUENCE FLAME CONTROL BOX.
THE FULL SEQUENCE FLAME CONTROL BOX ON THIS APPLIANCE REQUIRES A 6 SECOND RE-SET PERIOD FOLLOWING EACH INTERRUPTION OF INPUT VOLTAGE.
6 SECONDS DELAY IS REQUIRED BETWEEN EACH ATTEMPT TO RESTART THE APPLIANCE FOLLOWING SWITCHING IT OFF, OR AFTER OPENING THE DOOR.
7 AIRFLOW
It is most important that airflow to the plinth is not restricted.
8 MAINTENANCE
It is recommended that the appliance is serviced annually by a person competent to service gas fired tumble dryers.
9 STACKING
Instructions for stacking, if required, are supplied with the stacking kit.
PROGRAMME
Clockwise rotation of the control knob closes switch contacts within the timer to: a) energise the drive motor, and b) energise the full sequence flame controller.
The timer switch controlling the drive motor and the timer motor, remains closed until the timer motor mechanism returns the control knob to the '0' position. The timer switch controlling the full sequence flame controller opens 12 minutes earlier to provide a cool-down period.
The full sequence flame controller opens the tandem solenoid gas valves after a delay time of about 8 seconds and operates the pulsing spark ignition. If the flame is not detected by the flame failure electrode within 10 seconds then the valves are closed. The system must then be re­set by switching the machine off and re-starting.
The heat selector switch provides options for either 60°C, or 50°C, exhaust thermostat control. This results in the burner cycling on and off giving Ionger than anticipated drying times. Drying times vary depending on the weight and size of the articles, type of fabric, dampness etc. These thermostats turn off the heating towards the end of the chosen cycle and so avoid waste of energy. The lower temperature thermostat prevents delicate fabrics from getting too hot with possible risk of damage.
An inlet thermostat is fitted in the ducting at the back of the dryer. It may also operate under certain other conditions of restriction of the air-flow, for example, an overloaded drum or blocked lint filter. This thermostat switches off the flame controller. This will result in the burner cycling on and off giving longer than anticipated drying times. Drying times vary depending on the weight and size of the articles, type of fabric, dampness etc.
Should the thermostat fail there is an inlet cut-out connected in circuit with the gas valves. After operation, the cut-out must be re-set to restore heating but a service call may be required to correct the initial fault.
The conditions of failure of the air flow, blow-back, or of gas interruption are detected by the flame failure electrode and the system is shut-down.
Both drum rotation and heater control are switched off when the door is opened and switched on when the door is reclosed.
For programme times see chart on dryer control panel. Note: Do not allow fluff to accumulate around the dryer.
