Just wondering if anyone has ordered this? I just got mine the other day and they measure 6" wide. I don't know if they sent ones for the E140 or if they are for my E100. I thought they would fit right down on the ledge of the main refractory like the original ceramic nozzles do. So I'm not sure if I should lay them on top of the main refractory and fire it up or wait till Monday to call Alternate Heating. Any info is really appreciated because it's really cold up here and she wants me to get it started ASAP Lol.
