A lot of the glowbar ignition systems for propane ranges use a heater wound on a dissimilar metal bar to open the gas valve, this heater is in series with the glowbar so if the glowbar burns out the valve won't open, and while the heater is warming up in the valve the glowbar has time to get hot before the gas flows. This means that while the oven is burning the glowbar remains hot and probably draws a couple of hundred watts continuously, quite a load for an re system, not much on the grid.Very difficult to convert to standing pilot, the parts (new thermostat, pilot assy., and oven safety)would cost as much as a standing pilot range.
