INTRODUCTION

This instruction serves mainly for the user of this storage tank. It contains basic technical

information and steps necessary for putting the boiler into operation, for its smooth

attendance and basic rules of maintenance. Some chapters and information written in this

instruction are also meant as an informative guide for specialised organisations which will

carry out assembly of the appliance at user's.

WARNING!

To ensure the operation of the appliance without failures and because of own safety, it is

necessary to study this manual thoroughly and follow the steps and instructions included. The

part of the manual is also a record on putting the appliance to operation that will be made by

an authorised company. The list of authorised service organisations and the letter of

guarantee is a part of this manual. If the record is not filled properly, it can be a reason for not

acknowledging the reclamation.

All this manual together with the letter of guarantee and record on putting to operation must

be therefore kept carefully.

GENERAL TECHNICAL DESCRIPTION

The appliance works as a gas storage heater of water with waste gas exhaust to the flue. It

operates on natural gas. The appliance consists of a steel tank with a ceramic layer, outside

cover with thermal insulation of high quality, combined gas fitting, gas burner and

accessories.

PRINCIPLE OF WORKING

When putting the heater into operation, the ignition flame is burned with the help of a

piezoelectric lighter that burns the flame of the main burner. Heat arising from gas burning is

transferred through the bottom of the steel tank and smoke tube in the storage tank. After

reaching the temperature set by a thermostat (40-72), position 4: (about 55°C), the main

burner goes off automatically and only the ignition flame stays burning which is working non-

stop. The output of ignition burner is very low (about 100 W) and heat arising from burning is

used for further keeping the water temperature in the storage tank. Possible loses are

therefore minimalized.

The storage tank is equipped by a waste-gas thermostat that serves against back passage of

waste gas. When there is a failure in the waste gas exhaust, the operation of the heater is

stopped and gas supply into gas fitting is broken. Cutting out the sensor from the thermal fuse

circuit is inadmissible.

Polyurethane insulation keeps the reached water temperature with high effectivity (decrease

of water temperature is about 0.8 1°C/h). When the temperature in the storage tank decreases

in 5-6°C or when higher amount of hot water is taken off and cold water flows after, the

regulation thermostat enables reignition of the main burner and water is heated to the

temperature adjusted by a regulation button of gas fitting.

A combined safety valve (0,6 MPa) with a non-return flap valve that is activated for pressure

higher than 0,6 MPa is a part of the appliance. The valve opens when the pressure in hot water

distribution overcomes the critical value. After pressure decreasing the valve will close

automatically.
