190 mv DC
CHECKING THERMOPILE FOR PROPER VOLTAGE
Place the leads of the multimeter on the TP/TH and TP
terminals on the valve as shown.
With the switch in the “ON” position, the readings should
be approximately 190mV DC (this an average reading) or
greater for proper Thermopile operation.
The main burners may not come ON if the readings are
less than 145mV DC.
If a thermostat has been installed. Place the
ON/OFF/THERMO switch in the THERMO position; place
the leads of the multimeter on the TP/TH and TH terminals
on the valve or on the connections at the thermostat.
MV reading should be higher than 190 mV DC for proper
valve operation.
THESE READINGS SHOULD BE CONSTANT WITH NO
FLUCTUATION.
When using a S.I.T EUROSIT 630 SERIES gas valve, place
one lead from the multimeter on the thermocouple lead and
the other lead into the adapter located on the back of the
valve, there are two blue wire a inserted into this adapter.
2 to 6mv DC
THERMOCOUPLE
CHECKING
THERMOCOUPLE FOR
PROPER VOLTAGE
Place one lead from the
multimeter on the
thermocouple lead, and the
other lead from the
multimeter on the back of
the valve where the blue
wire is soldered to the valve.
These readings should be
between 8 and 16mV DC.
If these readings are 2 to 6
mV DC, the Thermocouple
should be replaced
