I don't believe your on cycle needs to gas. It should just add enough air to replace the oxygen depleated air (wood gas) surrounding the fuel. A small amount of air should maintain some sort of combustion in the coals. The way I run my EKO the cycle timer isn't needed because I "batch burn" one hot fire per day but the cycle timer still cycles on during the one idle period I get when the storage tank is near maximum temperature. I'm usually not far from the boiler at this time in the burn and I've witnessed the cycle. I don't know what it's set for and have forgotten how to set it but it only runs about 6 seconds. That doesn't mean yours should be that short because of the positive draft closure on the Wood Gun. It will take more time to purge the oxygen depleted gas from the chamber.
