If it was me I would try loading the pot 1/2 full or so and light it with a mapp-propane torch from the start and see what it does from there. If it has enough heat to start maybe then you could raise the heat-feed level to keep it going OK. If you had to open the door and drop in more pellets to get it hot I would do that.
It doesn't mean you can't replace the board later but it might get you going for now.
