Here is a link to the tech manual lwith minimum clearances for your unit -


https://www.manualslib.com/manual/198...


My suggestion - when you talk about removing the slide I presume you mean the slide-up front cover panel. Are you sure you are trying to remove it correctly - could not find a detailed diagram on that unit, but usually the panel has folded-in sides that guide along a vertical folded-out seam on each side of the unit, and the top and the bottom have an extended seam that fits down into a recess - so to remove the panel you lift it up an inch or more or as hjigh as needed to clear the top and bottom tabs fron the slots or recesses they sit in, then pull out to the front. Normally you need 1/2 - 1" front clearance to pull the panel free after lifting it up.


It may well be that shutting the unit down, maybe disconnecting gas line if rigid but at least shutting off the shutoff valve at pipe, maybe (or maybe not) disconnecting the flue and / or ducting (just disconnecting, not necessarily removing them) might provide enough slack to allow you to slide the unit the necessary inch or few to provide clearance. Might or might not be bolted down to whatever it is sitting on.


Another possible solution, being careful about not hitting wires or such inside - pry one edge of the panel lip out flat with the panel, so the panel can then be shoved sideways to clear. Would have to lift up enough to clear the top and bottom lips first, though.


Look at what the pillar is supporting - might be fairly easy to put in two temporary posts (one on each side) to support the beam or joist it is carrying - though if that is feasible I would just permanently install them so the offending post can just go away. Or depending on how the post is installed relative to the furnace, might be feasible to pattern-nail on secondary support boards on 3 sides and then (if this is not removing support under the beam) cut away an inch or so of the post on the side towards the furnace. Would want an experienced carpenter to do that.


Have an HVAC guy come out and relocate the furnace a foot or so away - whichever way fits OK and can be done without nasty flue or duct modifications - just modify them with duct or flue adapter pieces as necessary to move the unit over a bit. IF the flue and/or duting has a universal joint bend in it might not even take any adapter - just move it a bit and twist the bend piece to fit at a different angle - or put in a universal joint adapter to allow you to connect up slightly off alignment with the flue or duct, or to realign them further up the flue or ducting as necessary.


=======


If what you meant is you got the panel off but cannot remove the flower housing and fan/motor, then sounds to me like relocating the furnace or permanently replacing the post/column with a pair (if feasible considering what it is holding up) set off to the sides enough to provide good clearance would be the solution.


One thing I definitely would NOT do is cut into the side of the furnace to access it - that sort of modification, even if neatly covered over with a metal coverplate, would likely invoke a dirty comment from home inspector come resale time, possibly resulting in the buyer demanding replacement of the unit. Ditto to the possibility of future HVAC techs refusing to work on it because of the modification.
