First off, unvented heaters make people into Darwin award nominees (They
kill people).

Can anyone give me some info on ODS pilots?
I need to know what the normal range of voltage the ODS puts out.
Normal thermocouples will hold a magnet in at about 20mv.
Can't get the one I checked to go higher than 10-15mv
Thanks

The t-couple on a ODS equipped heater is a standard one. The difference is
the orifice that leads to the actual pilot. The orifice actually is a
specific size that a certain amount of oxygen goes through to keep the pilot
burning. If the oxygen content drops too low, the pilot 'impinges' on the
t-couple less, effectively killing the power generation.
