Where can I find a good schematic or diagram of the parts within a Heil furnace? Also, when purchasing parts, do they come with installation directions? I always want to try the initial install myself rather than paying for service calls first.

Most furnaces have a legand glued to a door that tell what the parts are, most, now,, parts don`t come with installation instructions,, if you go to replacing parts hoping to sooner or later replace the right part,, could get very expensive,, would probably save you money to call a technician
