1. INTRODUCTION
The Logic + Combi C is a combination boiler providing both central heating and instantaneous domestic hot water. Featuring full sequence automatic ignition and fan assisted combustion.
Due to the high efciency of the boiler, condensate is produced from the ue gases and this is drained to a suitable disposal point
through a plastic waste pipe at the base of the boiler. A condensate
‘plume’ will also be visible at the ue terminal.

OPERATION MODES Winter Conditions -
(Central Heating and Domestic Hot Water
required)
Set the mode knob (C) ‘ ’ (winter).
The boiler will re and supply heat to the radiators.
The domestic hot water preheat will operate with the preheat button set to ‘Preheat On’.
Summer Conditions - (Domestic Hot Water only required) Set the mode knob (C) to ‘
’ (summer).
Set the central heating demand on the external controls to OFF.
The domestic hot water preheat will operate with the preheat button set to ‘Hot Water On’.
Boiler Off
Set the mode knob (C) to ‘BOILER OFF’. The boiler mains power supply must be left on to enable frost protection (see Frost Protection).
PREHEAT - DOMESTIC HOT WATER
The domestic hot water heat exchanger within the boiler can be kept preheated to provide faster delivery of hot water at the tap. This is achieved by pressing the preheat button to “Preheat On”.
The boiler will operate periodically for a few seconds to maintain the domestic hot water heat exchanger in a preheated condition. The average time period between operation is 90 minutes. This may vary considerably due to the surrounding ambient temperature of the boiler. The boiler will operate whenever there is a demand for domestic hot water.
If standard hot water delivery is satisfactory set the preheat to ‘Preheat Off’.
5
CONTROL OF WATER TEMPERATURE
Domestic Hot Water
The domestic hot water temperature is limited by the boiler controls to a maximum temperature of 65
º
C, adjustable via the domestic hot water temperature knob (B). At low DHW draw off rates the maximum temperature may exceed 65ºC.
Approximate temperatures for domestic hot water:
Knob Setting Hot Water Temperature (approx.)
Minimum 40ºC Maximum 65ºC
Due to system variations and seasonal temperature
uctuations domestic hot water ow rates/temperature rise will vary, requiring adjustment at the tap : the lower the ow
rate the higher the temperature, and vice versa.
Central Heating
The boiler controls the central heating radiator temperature to a maximum of 80oC, adjustable via the central heating temperature knob (B).
Approximate temperatures for central heating:
Knob Setting
Central Heating Radiator Temperature (approx.)
Minimum 30ºC Maximum 80ºC
For economy setting ‘
’ refer to Efcient Heating System
Operation.
EFFICIENT HEATING SYSTEM OPERATION
The boiler is a high efciency, 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 ue gases when operating most efciently. To operate your boiler efciently (using less
gas) turn the central heating temperature knob (B) 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 tted to the system
then the central heating temperature knob (B) 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
The boiler is tted with frost protection that operates in all
modes, provided the power supply to the boiler is always turned on. If the water in the boiler falls below 5ºC, the frost protection will activate and run the boiler to avoid freezing. The process does not guarantee that all other parts of the system will be protected.
If a system frost thermostat has been installed, the boiler must
be set in winter mode, ‘
’, for the system frost protection
to run.
If no system frost protection is provided and frost is likely during a short absence from home it is recommended to leave
the system heating controls or built in programmer (if tted)
switched on and run 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 messages (see section 9) press “Restart”. The boiler will repeat its ignition sequence. If the boiler still fails to start consult a Gas Safe Registered Engineer or in IE a Registered Gas Installer (RGII).
MAINS POWER OFF
To remove all power to the boiler the mains power switch must be turned off.

3. SYSTEM WATER PRESSURE
The system pressure gauge (G - see page 4) 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 and continue to fall then a water leak may be indicated. In this event re-pressurise the system as shown below. If unable to do so or if the pressure continues to drop a Gas Safe Registered Engineer or in IE a Registered Gas Installer (RGII) should be consulted.
THE BOILER WILL NOT OPERATE IF THE PRESSURE HAS REDUCED TO LESS THAN 0.3 BAR UNDER THIS CONDITION.
To Top up the system :-

4. CONDENSATE DRAIN
This appliance is tted 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 displaying “Ignition Lockout” on the display. If the appliance is restarted it will make a gurgling noise prior to it locking out displaying “Ignition Lockout” on the display..
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 ow. 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 identied 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 ow
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 (B) to “MAX”, (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).
