1. intRodUCtion

The logic Combi eS 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 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.

In your own interest, and that of safety, it is the law that this boiler must be installed by a Gas Safe Registered Engineer, in accordance with the above regulations.

In IE, the installation must be carried out by a Registered Gas Installer

If a programmer is fitted refer to separate instructions for the programmer before continuing.

Start the boiler as follows:

1. Check that the electricity supply to boiler is off.

2. Set the mode knob (D) to ‘off’.

3. Set the Domestic Hot Water temperature knob (B) and Central

Heating temperature knob (C) to ‘max’.

4. Ensure that all hot water taps are turned off.

5. Switch on electricity to the boiler and check that all external controls, e.g. programmer and room thermostat, are on.

6. Set the mode knob (D) to ‘ ’ (winter).

The boiler will commence ignition sequence, supplying heat to the central heating, if required.

note.

In normal operation the boiler status display (E) will show codes:

Standby - no demand for heat.

Boiler frost protection - boiler will fire if temperature is below 5ºC.

During normal operation the burner on indicator (F) will remain illuminated when the burner is lit.

Note: If the boiler fails to light after five attempts the fault code

will be displayed (refer to Fault Code page).

ContRol of WAteR teMPeRAtURe

domestic Hot Water

The domestic hot water temperature is limited by the boiler controls to a maximum temperature of 64 º C, adjustable via the domestic hot water temperature knob (B).

Approximate temperatures for domestic hot water:

Knob Setting

Minimum

Hot Water Temperature (approx.)

40ºC (104ºF)

Maximum 64ºC (147ºF)

Due to system variations and seasonal temperature fluctuations domestic hot water flow rates/temperature rise will vary, requiring adjustment at the tap : the lower the flow rate the higher the temperature, and vice versa.

Central Heating

The boiler controls the central heating radiator temperature to a maximum of 80 o

C, adjustable via the central heating temperature knob (C).

Approximate temperatures for central heating:

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 (C) 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 fitted to the system then the central heating temperature knob (C) 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.

3. SySteM WAteR PReSSURe

The system pressure gauge (G - see page 3) 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.

To Top up the system :-

1. Ensure both A & b handles (blue) are in closed position (as shown below)

2. Remove the plug and cap and retain.

3.

Connect the filling loop to the Domestic Hot Water (DHW) inlet and tighten. Also ensure that the other end of filling loop is hand tight.

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, ‘ ’, 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.

To restart the boiler, when directed in the listed fault codes (see section 8), turn the mode knob (D) to ‘restart’ position and

Gas Safe Registered Engineer or in IE a Registered Gas Installer

(RGII).

4. 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 an “L2” fault code. If the appliance is restarted it will make a gurgling noise prior to it locking out on a failed ignition “L2” 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 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 Light 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

(C) 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).

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.
