I guess there could be any number of reasons why the dealer is doing things the way he is, but as I said, I have no choice.if you have the 13 fin igniter they were known for wearing out prematurely, hopefully the new 15 fin igniter will last a lot longer for you. The only reasons i can think of that the dealer doesn't want to test your igniter and send it back is one they don't know how to test them (which would be bad but not beyond belief for some dealers) and second they don't want to have to pay for the shipping. I dont know for a fact but i believe dealer pays return shipping on warranty items, i know my office guy saves up a bunch of warranty items before sending them back as one large lump. although i could be wrong on the shipping. 75% of items returned for warranty to HHT (Harman,quad,heatilator,etc) are STILL GOOD. so now they are offering trainings to dealers to try to get better techs that don't just throw parts at the stove. so the whole not getting paid for warranty is not true at all. One day they will implement warranty where you don't get paid unless justified but it hasn't happened yet.
As far as the running the stove without the igniter that should not hurt a thing, i would put the bracket back in so as to close off the holes in the front of the pot for the screws that hold the igniter bracket, but other than that you can run the stove with out the igniter itself in the bracket and not hurt anything.
Thanks for the info on running without an igniter in place. That is exactly what I'll do. What I was going to do before this aforementioned scenario came about was just get the replacement igniter and put it in at the end of the heating season when I do my off season cleaning. I can still do that, but now having to take it out to send to them, I will be doing everything twice.
