TECHNICAL INFORMATION

1. GENERAL INFORMATION

MTS (GB) Limited support the initiative.Your installer will give you, and show you how to use, a Log Book which will give you impor tant information about your boiler, and heating system. Please have this Log Book to hand whenever you contact a service engineer or us.

All CORGI Registered Installers carry a CORGI ID card, and have a registration number. Both should be recorded in your boiler Logbook. You can check your installer is CORGI registered by calling CORGI direct on :- (01256) 372300.

This is a combined appliance for the production of Central Heating (C .H.) and Domestic Hot Water (D.H.W.). This appliance must be used only for the purpose for which it is designed. The manufacturer declines all liability f or damage caused by improper or negligent use. Do not allow children or inexperienced persons to use the appliance without supervision. If you smell gas in the room, do not turn on light switches, use the telephone or any other object which might cause sparks. Open doors and windows immediately to ventilate the room. Shut the gas mains tap (on the gas meter) or the valve of the gas cylinder and call your Gas Supplier immediately. If you are going away for a long period of time, remember to shut the mains gas tap or the gas cylinder valve.

Before any intervention within the boiler it is first necessary to isolate the electrical power supply by turning the external switch to “OFF”.

CAUTION!! Installation, start-up, adjustments and maintenance must be performed by a competent

person only in accordance with the current Gas Safety (Installation & Use) Regulations and the instructions provided. Improper installation may cause damage or injury to individuals, animals and personal property, for which the manufacturer will not be held liable. To ensure efficient and safe operation it is recommended that the boiler is serviced annually by a competent person. If it is known or suspected that a fault exists on the appliance, it must not be used until the fault has been corrected by a competent person.

Helpful Suggestions

To get the most out of your boiler, we have provided you with some useful advice on proper use and maintenance:

- Periodically check the system pressure using the pressure gauge “E” and make sure that the pressure is between 1.0 and 1.5 bar (the blue part

of the gauge) when the system is off and

cool.If the pressure is below the minimum recommended value, the pressure must be brought into the acceptable range.Consult your installer for checking and refilling the system. If the pressure level drops on a frequent basis, it is likely that there is a water leak in the system. If this is the case, your installer must inspect the system.

- The outer panels of the boiler's case must only be cleaned with a damp cloth, do not use abrasive cleaners.The Control panel can be wiped with either a damp or dry cloth. Spray polishes must not be used on the control panel surface or knobs .Care must be taken in preventing any liquid entering the appliance.

- If the water is exceptionally hard, install a water softener so that the efficiency of the boiler remains the same over time, as this will consume less gas.

- To improve comfort levels and take full advantage of the heat produced by the boiler, it is necessary that an external thermostat and an outdoor sensor be installed.

- When the boiler is not in use for prolonged periods shut it down by turning the knob “A” to the off position and close the gas and water isolation valves.

MPORTANT

!) This will disable the anti-frost device - if the period of disuse is very cold it will also

be necessary to drain the heating system of water. If you wish to leave the anti-frost de vice activ e, it is necessary to leave the boiler on:this will not safeguard from possible "blocks" which may impair this function.

- It is good practice to clean and service the appliance and Central Heating System every year. Call a CORGI registered gas installer.
