We are looking at a house, and the wall heater pilot looks strange to me. There are 2 flames, not one. One above, one below. Is this a leak in the pilot gas line? Or something else?
The thermostat is not working so we can't fire up the heater. When I try to light the pilot it stays lit, but 2 flames.
A pilot leak in the wrong place might even be the reason the unit is not working.
Many pilot heads divide the flame between the thermocoupler/flame sensor (safety device)
and the main burners they need to ignite. Wall heaters pilots can even have a spiral flame around an interior power pile which puts the flame on different heights and positions.
