INTRODUCTION
The Logic System2 S is a system boiler, featuring full sequence automatic spark ignition and fan-assisted combustion. Due to the high efficiency of the boiler, condensate is produced from the flue 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 flue terminal.

To START the boiler
-
Switch on electricity to the boiler and check that all external controls e.g. programmer, room thermostat and cylinder thermostat are all on.
-
If OFF is shown at the bottom of the screen press the Mode button (B) so that ON appears.
-
Turn the Temperature control knob (A) until 80°C is shown. Once the boiler has lit see the following page about where the Temperature control knob should be set.
Note. In normal operation the boiler status display (C) will display messages.- Refer to Section: 1.7
Boiler frost protection – boiler will fire if temperature is below 5°C. During
normal operation, the burner symbol ‘ ’ will remain illuminated when the
burner is lit. If the boiler fails to light after five attempts the following
fault messages will be displayed:
To restart the boiler, press Restart (E). The boiler will repeat the ignition sequence. If the boiler still fails to light consult a Registered Gas Installer.
OPERATION MODES
- Winter/Summer Conditions – (Domestic Hot Water is required, Central Heating may be required) If OFF is shown at the bottom of the screen then press the Mode button (B) so that ON appears. The boiler will fire and supply heat to the hot water cylinder and radiators.
- Boiler Off – (neither Domestic Hot Water or Central Heating required)
If ON is shown at the bottom of the screen then press the Mode button (B) so that OFF appears.
CONTROL OF WATER TEMPERATURE
-
No Outside Sensor Connected
If no outside sensor is connected then the temperature of the water leaving the boiler to go to either the radiators or the hot water cylinder can set be anywhere between 80°C and 30°C by rotating the Temperature Control Knob (A) clockwise or anti-clockwise. -
Outside Sensor Connected
If an outside sensor is connected then the temperature of the water going to the hot water cylinder is factory set to 80°C (but the temperature of the hot water to the tap is set by the thermostat on the hot water cylinder). The nominal central heating room temperature can be set anywhere between 30°C and 10°C by rotating the Temperature control knob (A) clockwise or anti-clockwise (if you are too cold rotate the knob clockwise, if you would like to run your central heating more efficiently rotate the knob anti-clockwise). 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) lower. In
winter periods it may be necessary to turn the knob towards a higher
temperature 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%.
BOILER FROST PROTECTION
The boiler is fitted 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, “(there should not be a
cross through the radiator symbol)”, 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 fitted) switched on and run at a reduced temperature
setting. For longer periods, the entire system should be drained.
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:
- If you do not feel competent to carry out the defrosting instructions below please call your local Gas Safe Registered installer for assistance.
- 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 before locking out, showing an L0d or “LO2” fault code. If the appliance is restarted it will make a gurgling noise prior to locking out, showing an LO2 fault code.
To unblock a frozen condensate pipe;
- 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. The pipe is likely 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.
- 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.
- Caution when using warm water as this may freeze and cause other localised hazards.
- Once the blockage is removed and the condensate can flow freely, restart the appliance. (Refer to “To Start the boiler”)
- 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).
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 above, 100mm below, 2.5mm at the sides and 450mm 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 enable the system pressure gauge
to be visible and 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.
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 while 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 (E) to restart the boiler. If unable to do so or if the pressure continues to drop after filling a Gas Safe Registered Engineer should be consulted.
Note. The boiler will not operate if pressure has reduced to less than 0.3 bar under this condition.
POINTS FOR THE BOILER USER
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 before requesting a service engineer 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.
