Introduction This product will be marketed in the following European Union member states: GB - HU - ES Directive 97/23/CE The boilers and hot water tanks are designed and manufactured in accordance with the sound engineering practice, as requested in article 3.3 of the directive 97/23/EC; it is certified by compliance with the directives 90/396/EC, 92/42/EC, 73/23 EC and 89/336/EC.
Description 1 Introduction Gas 360 S boilers are made of cast iron: - with atmospheric gas burners - with electronic ignition via the ignition burner for hot water central heating - with a useful output of between 54 and 117 kW The figure given after Gas 360 S indicates the number of sections which make up the boiler. Gas 360 S boilers are delivered with a K control panel. They can be fitted with an optional RC4 and RC5 control unit (master-slave control unit options).

Operation 1 Furnace operation equipped with safety box S4565 BF 1161 Operating principle The ignition and burner surveillance sequences are ensured by the safety box. Behaviour in normal conditions If needed, the boiler thermostat TCH1 closes the contact. The ignition transformer TA integrated into the safety control box and the ignition burner valve VBA (supply to the ignition burner) are switched on.

Adapting to another gas Valid for switching from natural gas H/E to propane and vice versa. 1 Changing the burner nozzles - Remove the nozzles with a 12 mm spanner and fit the new nozzles with their new seals. First tighten the nozzles by hand and carefully lock them using a spanner. Carry out a leak tightness check. 2 Changing the ignition burner injector Unscrew the connecting nut (14 spanner), Fit the new nozzle . Pull the gas supply pipe towards yourself.
3 Setting the nozzle pressure Pressure socket The pressure must be set by a qualified professional. The boiler must be commissioned after having checked the points covered in this chapter: Final checks before commissioning. - Connect the manometer to the left or right pressure outlet on the manifold. - Turn the boiler on. Set the boiler thermostats to maximum. - Unscrew the protection cap on each valve.
4 Setting the start up pressure 1/4 turn Natural gas Propane or If necessary, the start-up pressure can be set on the right valve (1st stage) using a flat screwdriver. To modify this setting, it necessary first to remove the protection using a screwdriver (1/4 turn). In the factory, it is set to maximum..

2 Final checks before commissioning first start-up is to be performed by your installation The engineer. Check the following points before starting the heater: Hydraulic circuit: `Check that the installation and boiler are adequately filled with water and correctly irrigated and bled. `Check that the hydraulic connections are leak tight. Gas circuit: `Check the adjustment of the gas line: - Connect a manometer to the pressure socket located on the manifold.
Maintenance 1 Checking and cleaning the main components 1.1 Cleaning heater body The extent of clogging on the heating body must be checked once a year. If it is necessary to sweep the boiler, remove the burner drawer to prevent deposits and soot blocking the orifices in the gas trains.
1.2 Cleaning main burner and ignition burner The main burner and the ignition burner injector with its filter must be regularly cleaned to ensure good performance. We recommend doing this at least once a year.
Incidents and solutions Symptoms Probable causes Solution The heater does not start - The heater thermostat is and the safety box is not requiring heat - Create a demand by moving the heater thermostat or the setting level affected (red alarm - Setting (option) is not requiring (option). indicator off) heat. - The safety thermostat has been - Solve the cause of overheating and reset the safety thermostat. triggered after overheating.
Symptoms Noisy heater Probable causes Solution - Poor purge - Purge correctly - Body has scale - Descale the heating circuit - Unsuitable injectors (Whistling) - Check injectors Heater too hot or too cold - 3 position switch on position ! - Check the position of the 3 position switch for requirements - Wrong setting for the heater - Set the heater thermostat if the heater has SV-matic setting or an ambient thermostat thermostat Flame returns - Injectors too large - Pressure too weak - Check pres
