I was wondering if any of you in the HVAC field could give me some
advice? Is it possible to 'box' in a hw tank and a high effic.
furnace? What I guess I am asking is how much clearance is needed? I
have a small wood shop that shares space with these heaters and I am
curious if I can put up a wall to keep the dust to the units at a
minimum. I could vent the enclosure also if required...
Can anyone help??
If we are needing to quote codes, etc.... I am in Ontario...
Thanks for the reccomendation. As far as I know, the high. effic.
furnace I have vents outdoors through a pvc stack. I suppose I should
get an HVAC guy in to give me the real skinny on this one.
The vent you're describing is the exhaust vent. An equal volume of air
must be allowed to come into the house ("make up air") from somewhere or
the furnace won't function properly.

I think that the other pcv pipe allows 'make up air' to be pulled from
outside. There are 2 pvc pipes coming off the furnace and all of the
parts on the unit itself appear sealed (with the exception of a small
removable strip of metal to house the 25x16x1 filter media.
I could be wrong... it has happened many times before... lol
Your manuals for the appliances will state the clearances to
combustibles for each unit. Be concerned about makeup air unless your
furnace is a condensing unit with pvc 2" pipe bringing in combustion
air. Makeup air vent area is based on the btu of your appliances. Howe
Thanks kindly for the great info... I had not idea that the enclosure
restraints would be based on btus. My furnace does have the pvc stack
as you mentioned. My real concern I guess would be the hw heater as
it's a conventional design and is ng powered.
