6.  REGULATION AND SAFETY EQUIPEMENT

6.1  General

The Remeha Gas 350 is supplied with electronic control 
and safety equipment with ionisation fl ame detection.

6.2  Instrument panel

The Remeha Gas 350 is supplied with an instrument 
panel that is fi tted in the front of the boiler. The standard 
instrument panel can be extended with the fi tting of 
the following options: hour run meters, water pressure 
switch, down draught thermostat, no volt contacts and/or 

rematic

®

 control.

All connections are pre-wired and fi tted with plugs. The 
capillaries from the control panel should be fi tted in the 
pocket of the boiler, which is fi tted in the fl ow connection 
of the boiler.

6.3.2  Specifi cation

1  Pilot gas valve
1  Pilot burner with ionisation probe
  and ignition probe.

6.3.3  Control panel behind front panel

1  Control box Satronic
1  Ignition transformer 16 kV.

6.4  Functions

6.4.1  Flame protection

Flame protection by means of ionisation fl ame detection.

6.4.2  Down draught thermostat

Optional the boiler can be fi tted with a down draught 
thermostat. When there is down draught of the fl ue gases 
this thermostat will switch off the boiler. 
Fixed setpoint is 70°C.

6.4.3  Thermostats

Control thermostat On/Off 35°-95°C.
Control thermostat High/Low 35°-95°C.
High-Limit thermostat locks out at 110°C.
