3 Technical description
3.1 General description
Boilers in the GAS 360 S range have the following characteristics:
- Cast iron floor-standing gas boiler.
- Connecting to a chimney.
- Atmospheric burner (2 stages).
- Heating body in cast iron with overlapping studs making it possible
to obtain extremely high efficiency. Also, the baffling in the smoke
circuits limits the natural chimney effect and gives high
performance yields.
- Efficient insulation of the entire boiler unit for very low losses to the
ambient air.
The figure given after Remeha Gas 360 S indicates the number
of sections which make up the boiler.
For example: Remeha Gas 360 S/8: 8 section boilers

3.4 Operating principle
S4565 BF 1161 safety box The ignition and burner surveillance sequences are ensured by the
safety box.
Normal operating cycle
If heating is required, the boiler thermostat TCH 1 closes the contact.
The ignition transformer TA integrated into the safety control box and
the safety flap on the gas valve (supplying the ignition burner) are
switched on.
Gas from the ignition burner is ignited by the ignition electrode and
within the time interval ts; a minimum current of 0.9 µA appears on
the ionization sensor SF and the gas valve regulation flap (supplying
the principal burner) opens.
If, moreover, TCH2 is required, the 2nd stage valve VP2 opens.
Operating cycle on safety (start up without flame signal)
- If the flame is not detected before the end of the safety time ts, the
safety control box goes into safety lockout and the safety lockout
warning light comes on.
To restart the heater, press the reset button on the safety box.
- If there is a loss of flame in normal operation, the box automatically
repeats the start up sequence.
- If a flame is present before start-up, the safety control box remains
on standby.

Resetting
The box is reset after going into safety by pressing the reset button.
If the reset button does not work, wait at least 15 seconds before
trying a second time.
After activating the reset button, the warning light goes out and the
safety control box restarts after a waiting time of around 1 minute.
The box may be on safety on its first start up: press the reset
button to release it.
If the reset button is pressed in normal operation, the gas valves
close and the box starts a new ignition sequence.

4.3.2 Ventilation
Caution:
In order to avoid damage to the boiler, it is necessary to prevent the
contamination of combustion air by chlorine and/or fluoride
compounds, which are particularly corrosive. These compounds are
present, for example, in aerosol sprays, paints, solvents, cleaning
products, washing products, detergents, glues, snow clearing salts,
etc. Therefore:
- Do not pull in air evacuated from premises using such products:
hairdressing salons, dry cleaners, industrial premises (solvents),
premises containing refrigeration systems (risk of refrigerant
leakage), etc.
- Do not stock such products close to the boilers.
If the boiler and/or peripheral equipment are corroded by such
chloride or fluoride compounds, the contractual guarantee
cannot be applied.
The combustive air must reach the burner from the
front.
The location of air inlets in relation to the high ventilation openings
shall ensure that the air is renewed in the entire volume of the boiler
room.
Please refer to the prevailing regulations in your country.
