I just installed a new ignitor in my Enviro Mini and it is working very well. My question is this, after I installed the new ignitor I kept the side cover off of the stove to watch the ignitor heat up and noticed that even after the stove has started the ignitor continues to glow hot. Is the ignitor supposed to stay on the whole time the stove is running? Seems like it should shut off after some sort of time goes by.
