I think my igniter is shot and read a few posts about igniters from Grainger being much cheaper. I believe I found the replacement for mine but I have one question about the length. On the side of the one that came with the stove it says 300W 120V and it measures 3/8 diameter , my question is the length, mine is 4" to the bottom of the collar but then there is a about an inch after the collar stop that the leads come out of. Graingers is 4" from tip to leads, they don't seem to have a collar stop and the next step up would be a 5". Here are the links from Grainger, anyone ordered one in the past and know the correct one to order? Thanks. http://www.grainger.com/Grainger/VULCAN-Thunderbolt-Cartridge-Heater-2E911?Pid=search http://www.grainger.com/Grainger/TE...m_sp=IO-_-IDP-_-BTM_BTB05209020&cm_vc=IDPBBZ2 I did notice that the 4" Vulcan states under applications that it is designed for concentrated heat in a limited space for close fit insertion and is rated to 1600 deg. F but the 5" one doesn't mention anything like that.
