i recently purchased a used envirofire ef2 and had help from family hooking it up. for the most part its been running awesome, but occassionally goes out when its set to half on the feed dial. now that ive been looking at it more closely and i downloaded a manual for it i realize it doesnt have many features that are shown in the manual. theres no igniter tube or an existing spot for one, no slider/damper rod and no heat exhanger tube cleaning rod. there are no spots for either of the rods that i can see. all this stove has is the green light, auger dial, blower dial and the manual/auto switch. is any of this a problem? is there another way I'm supposed to control the airflow to the stove? any info is appreciated!
