1. INTRODUCTION

The Logic + System S 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 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.

TO START THE BOILER

If a programmer is tted refer to separate instructions for the

programmer before continuing.

Start the boiler as follows:

Check that the electricity supply to boiler is off.

2. Set the mode knob (B) to ‘BOILER OFF’.

3. Set the Central Heating temperature knob (A) to ‘MAX’.

Switch on electricity to the boiler and check that all external

4. 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 being supplied

FP Boiler frost protection

- boiler will re 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 ve 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:

’ refer to Efcient Heating System

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 (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 tted 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 tted) 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 tted) 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.

3. 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.

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 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.

Once the blockage is removed and the condensate can ow

4. 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).

5. GENERAL INFORMATION

BOILER PUMP

The boiler pump will operate briey 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 ames 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 nish 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).

4. 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 lling loop to 1 bar (if unsure contact your installer). Turn off the tap on the lling loop and press the

“RESTART” button to restart the boiler.

If unable to do so or if the pressure continues to drop after lling

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.
