The Logic Max Heat2 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.
Current Gas Safety (Installation & Use) Regulations or rules in force.
It is the law that this appliance installation and any work carried out on the appliance is carried out by a Gas Safe Registered engineer in accordance with the above Regulations.
It is essential that the instructions in this booklet are strictly followed, for safe and economical operation of the boiler.
This appliance must be earthed.
Supply: 230 V ~ 50 Hz. The fusing should be 3A.
Legend
Start the boiler as follows:
Once the boiler has lit see the following page about where the Temperature Control knob should be set..
In normal operation the boiler status display (D) will display messages.
Boiler frost protection - boiler will fire if temperature is below 5ºC.
During normal operation the burner on symbol (C) 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.
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 and tap 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.
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 | Central Heating Radiator Temperature (approx.) |
Minimum | 30ºC |
Maximum | 80ºC |
For economy setting [ ] refer to 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 Temperature Knob clockwise until an 80°C target is shown 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%.
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.
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 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.
To restart the boiler, when directed in the listed fault messages press the "Restart" button. The boiler will repeat its ignition sequence. If the boiler still fails to start consult a Gas Safe Registered Engineer.
To remove all power to the boiler the mains power switch must be turned off.

BOILER RESTART PROCEDURE - To restart boiler press the restart button
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 prior to requesting a service engineers 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.
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 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;
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).
Clearance of 165 mm (6 1/2") above, 100 mm (4") below, 2.5 mm (91/8") at the sides and 450 mm (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 5 mm
When the boiler has been installed for more than 1 year the following message will appear on screen:
Press "Restart" to clear this message.
Should a gas leak or fault be suspected contact the
National Gas Emergency Service without delay.
Telephone 0800 111 999.
Ensure that;
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 frequency of servicing will depend upon the installation condition and usage but should be carried out at least annually by a Gas Safe Registered Engineer.
The display scrolls through a maximum of 3 messages under any operational condition, as shown above
Note. The temperatures shown below are for illustration purposes only. The measured temperatures will be shown on the boiler.
