1.1 INTRODUCTION
The Logic Max System2 S IE is a system 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.
Safety
Current Gas Safety (Installation & Use) Regulations or rules in force. The installation must be carried out by a Registered Gas Installer (RGII) and installed in accordance with the current edition of I.S. 813 "Domestic Gas Installations", the current Building Regulations and reference should be made to the current ETCI rules for electrical installation.
It is essential that the instructions in this booklet are strictly followed, for safe and economical operation of the boiler.

OPERATION MODES

Winter Conditions - (Central Heating and Domestic Hot Water required)

If a Boiler symbol is shown on the display then press Mode

until either Ready or On is shown under the Boiler symbol. If

Tap & Radiators symbols are shown then press Mode until

Ready or On is shown under the radiator symbol. [

].

The boiler will fire and supply heat to the radiators.

Summer Conditions - (Domestic Hot Water only required)

If a Boiler symbol is shown on the display then central heating must be disabled at the timer or room thermostat. If Tap and Radiators symbols are shown on the display then press Mode until Ready or On is shown under the Tap and Off is shown under the Radiator. [ ].

Boiler Off

If a Boiler symbol is shown on the display then press Mode until Off is shown under the Boiler symbol. If Tap and Radiator symbols are shown on the display then press Mode until Off is shown underneath the Radiator symbol.

CONTROL OF WATER TEMPERATURE 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 Minimum Maximum

Central Heating Radiator Temperature (approx.) 30ºC 80ºC

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 temperature control knob (B) until
the leaf symbol is shown [ ]. In winter periods it may be necessary to turn the knob towards a higher temperature 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 (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 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.

3

USER

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, with Ready or On [ Ready or On ] shown under either the Boiler or 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 running 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 4) press the "Restart" button. The boiler will repeat its ignition sequence. If the boiler still fails to start consult a Gas Safe Registered Engineer.
MAINS POWER OFF
To remove all power to the boiler the mains power switch must be turned off.

1.3 SYSTEM WATER PRESSURE

2 bar

The system pressure gauge indicates the central heating system pressure. If the pressure is

seen to fall below the original installation pressure over a period of time and continue to fall

1 bar

1.5 UNBLOCKING A 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 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 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 Registered Gas Installer (RGII)

Preventative Solutions

During cold weather, set the central heating temperature knob (B) to "MAX", (Remember to 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).
