ideal HEATING H12 Logic Heat Regular Gas Boiler
INTRODUCTION
The Logic Heat 2 H is a heat only boiler, featuring full sequence automatic
spark ignition and fan assisted combustion. It is designed to provide central
heating and hot water when a separate hot water cylinder is installed.
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.

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. 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 required, Central Heating may be required)
If OFF is shown at the bottom of the screen then press the Mode button 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 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 (B) clockwise or anticlockwise. -
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 (B) 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 (B) 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.
FROZEN 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, showing an L0d or “L2” 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. 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.
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 local ised 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 (B) 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).
