We have a new Monogram dual fuel (converted to LP). It works great except the two dual flame burners click about 6-8 times when started after having sat for a few hours or overnight. When they do start, they have a large flare up. Subsequent starts are normal … 1-2 clicks then a normal flame start up. Service tells me that this is normal (?). Has anyone experienced this with a dual flame burner running on LP?
