• H. Central Heating Economy Setting

TO START THE BOILER

If a programmer is fitted refer to separate instructions for the programmer before continuing.

Start the boiler as follows:

1. Check that the electricity supply to the boiler is off.
2. Set the mode knob (B) to ‘BOILER OFF’.
3. Set the Central Heating temperature knob (A) to ‘MAX’.
4. Switch on electricity to the boiler and check that all external controls, e.g. programmer, room thermostat and hot water cylinder thermostat are on.
5. Set the mode knob (B) to ‘BOILER ON’. The boiler will commence ignition sequence, supplying heat to the central heating, if required.
   Note. In normal operation, the boiler status display (C) will show codes:
   00 Standby – no demand for heat.
   Central Heating is being supplied
   FP Boiler frost protection – boiler will fire if temperature is below 5ºC.

During normal operation the burner on indicator (D) will remain illuminated when the burner is lit.
Note : If the boiler fails to light after five attempts the fault code L 2 will be displayed (refer to Fault Code page).

To Turn Off
Set the mode knob (B) to ‘BOILER OFF’.

CONTROL OF WATER TEMPERATURE

The boiler controls the central heating radiator temperature to a maximum of 80oC, adjustable via the central heating temperature knob (A).
Approximate temperatures for central heating

For economy setting ‘ ’ refer to Efficient Heating System Operation.

EFFICIENT HEATING SYSTEM OPERATION

• The boiler is a high efficiency, condensing appliance which will automatically adjust its output to match the demand for heat.
• Therefore gas consumption is reduced as the heat demand is reduced.
• The boiler condenses water from the flue gases when operating most efficiently. To operate your boiler efficiently (using less gas) turn the central heating temperature knob (A) to the ‘ ‘ position or lower. In winter periods it may be necessary to turn the knob towards the ‘MAX’ position to meet heating requirements. This will depend on the house and radiators used.
• Reducing the room thermostat setting by 1ºC can reduce gas consumption by up to 10%.

WEATHER COMPENSATION

When the Weather Compensation option is fitted to the system then the central heating temperature knob (A) becomes a method of controlling room temperature. Turn the knob clockwise to increase room temperature and anti-clockwise to decrease room temperature. Once the desired setting has been achieved, leave the knob in this position and the system will automatically achieve the desired room temperature for all outside weather conditions.

BOILER FROST PROTECTION

• If the system includes a frost thermostat then, during cold weather, the boiler should be turned OFF at the programmer (if fitted) ONLY. The mains supply should be left switched ON, with the boiler thermostat left in the normal running position.
• If no system frost protection is provided and frost is likely during a short absence from home it is recommended to leave the heating controls (if fitted) at a reduced temperature setting.
• For longer periods, the entire system should be drained.

BOILER RESTART
To restart the boiler, when directed in the listed fault codes (see section 8) press the “RESTART” button (F). The boiler will repeat its ignition sequence. If the boiler still fails to start consult a Gas Safe Registered Engineer or an IE Registered Gas Installer (RGII).

MAINS POWER OFF
To remove all power to the boiler the mains power switch must be turned off.

CONDENSATE DRAIN

This appliance is fitted with a siphonic condensate trap system that reduces the risk of the appliance condensate from freezing. However should the condensate pipe to this appliance freeze, please follow these instructions:

• a. If you do not feel competent to carry out the defrosting instructions below please call your local Gas Safe Registered installer for assistance.
• b. If you do feel competent to carry out the following instructions please do so with care when handling hot utensils. Do not attempt to thaw pipework above ground level.

If this appliance develops a blockage in its condensate pipe, its condensate will build up to a point where it will make a gurgling noise prior to locking out an “L 2” fault code. If the appliance is restarted it will make a gurgling noise prior to it locking out on a failed ignition “L 2” code.

To unblock a frozen condensate pipe;

1. Follow the routing of the plastic pipe from its exit point on the appliance, through its route to its termination point. Locate the frozen blockage. It is likely that the pipe is frozen at the most exposed point external to the building or where there is some obstruction to flow. This could be at the open end of the pipe, at a bend or elbow, or where there is a dip in the pipe in which condensate can collect. The location of the blockage should be identified as closely as possible before taking further action.
2. Apply a hot water bottle, microwaveable heat pack or a warm damp cloth to the frozen blockage area. Several applications may have to be made before it fully defrosts. Warm water can also be poured onto the pipe from a watering can or similar. DO NOT use boiling water.
3. Caution when using warm water as this may freeze and cause other localised hazards.
4. Once the blockage is removed and the condensate can flow freely, restart the appliance. (Refer to “To Start the boiler”)
5. If the appliance fails to ignite, call your Gas Safe Registered engineer.

Preventative solutions

• During cold weather, set the central heating temperature knob (A) to maximum, (Must return to original setting once cold spell is over).
• Place the heating on continuous and turn the room thermostat down to 15ºC overnight or when unoccupied. (Return to normal after cold spell).

LOSS OF SYSTEM WATER PRESSURE
The gauge (G) indicates the central heating system pressure. If the pressure is seen to fall below the original installation pressure of 1-2 bar over a period of time then a water leak may be indicated. In this event conduct the re-pressurising procedure as follows:
Re-pressurise via the filling loop to 1 bar (if unsure contact your installer). Turn off the tap on the filling loop and press the “RESTART” button to restart the boiler.
If unable to do so or if the pressure continues to drop after filling a Gas Safe Registered Engineer or in IE a Registered Gas Installer (RGII) should be consulted.
NOTE. THE BOILER WILL NOT OPERATE IF PRESSURE HAS REDUCED TO LESS THAN 0.3 BAR UNDER THIS CONDITION.

GENERAL INFORMATION

BOILER PUMP
The boiler pump will operate briefly as a self-check once every 24 hours, regardless of system demand.

MINIMUM CLEARANCES
Clearance of 165mm (6 1/2”) above, 100mm (4”) below, 2.5mm (1/8”) at the sides and 450mm (17 3/4”) at the front of the boiler casing must be allowed for servicing.

Bottom Clearance

Bottom clearance after installation can be reduced to 5mm This must be obtained with an easily removable panel to provide the 100mm clearance required for servicing.

ESCAPE OF GAS
Should a gas leak or fault be suspected contact the National Gas Emergency Service without delay. Telephone 0800 111 999.

Ensure that;

• All naked flames are extinguished
• Do not operate electrical switches
• Open all windows and doors

CLEANING
For normal cleaning simply dust with a dry cloth. To remove stubborn marks and stains, wipe with a damp cloth and finish off with a dry cloth. DO NOT use abrasive cleaning materials.

MAINTENANCE
The appliance should be serviced at least once a year by a Gas Safe Registered Engineer or in IE a Registered Gas Installer (RGII)

POINTS FOR THE BOILER USER

Note. In line with our current warranty policy we would ask that you check through the following guide to identify any problems external to the boiler prior to requesting a service engineers visit. Should the problem be found to be other than with the appliance we reserve the right to levy a charge for the visit, or for any pre-arranged visit where access is not gained by the engineer.
