I have a Willaims wall mounted gas furnace model number 3003612. I would like to remove it. I have looked at the installation instructions and still can't seem to reverse engineer and remove the furnace.I have removed the screws holding the furnace body to the wall but it won't budge. I also tried removing the screws that hold the vent cap to the exterior wall and the vent cap won't come off either.Am I missing some attachment around the vent tubing? Is there possibly some corrosion around the vent tubing that's making it difficult to remove the furnace? I don't want to pull too hard on it in case there's screws I haven't removed. via /r/DIY https://ift.tt/2tNbnkK
