Vent question for a wall mounted heater ?

I'm look to install a 25,000 BTU (gas) wall mounted heater in my house just like this one:

Monterey 25,000 BTU/Hr Top-Vent Gravity Wall Furnace Natural Gas with Wall or Cabinet-Mounted Thermostat-2509622A - The Home Depot

According to the manual, the heater should be vented through the attic and out through of the roof.

My question is, does the vent line have to be a straight shot from the top of the heater to my roof or can i install a duct that bends and connects to an existing, unused vent on my roof?

If it's the latter, then it would save me a lot of hassle of having to cut into my room and install a new vent.

Thanks!

If I am looking at the correct model of heater,it can only be vented out the back of the unit.
I could be wrong.

It is top vented. If memory serves me you must have at least two feet of vent pipe off the furnace before any offset can be made. Of course you must refer to mfg instructions

I believe this is the installation manual for the furnace you are talking about:
http://www.homedepot.com/catalog/pdf...0ce79da302.pdf

See page 14 for venting. mbk3's memory is correct. No offsets within the first 2 feet of vent.

Thanks guys, that's the page I was looking for. Looks like I have to wait 2ft above the header and make sure the offset is no greater tha 45 degrees from straight up.

I don't think that qualifies, I believe it must be type "B" all the way
