The Yoder Smokers YS Series Ceramic Pellet Grill Igniter sits inside metal housing which directs the heat towards the pellets in the burn grate. This creates heat with no direct igniter contact meaning your igniter will last much longer and stand up to heavier use. Existing Yoder Smoker pellet grill users can upgrade to this igniter style with the instructions included in the packaging. This kit includes the ceramic igniter piece and the housing (does not include burn grate).
