Are you using it for a liner, going up an existing flue or chimmney? Or going straight out the wall?
 
If is is going up a masonry chimney yes, as long as it is properly rated flexible pipe. Most pellet stove pipe manufacturers sell a flexible pipe and stipulate that it is meant for masonry chimneys only.

If by 'hose' you mean 'rubber' hose - this is not a good idea. The effluent from pellet stoves are much to0 hot to vent through any sort of plastic or rubber material.

In Dutches County (NY) pellet stoves have to be vented through a double walled UL listed pipe or, if vented through a large existing chimney, they must still be run in a single walled stainless pipe (a vent kit with 4" flexable stainless pipe). I was never able to figure out what 'large' chimney meant - but after some effort I was told it is a fireplace chimney - as in fire place insert.

What I know as 'flexi vent' is really PVC clothes dryer exhaust pipe. That stuff will definately catch fire!

what i mean is a 3in metal hose from the back of a pellet stove to the direct vent kit. dont want to put a hole through the wall for one stove then change stoves n have to put anouther hole in the wall because they have different exauhst hights.
 
Cameran:
That one I can't answer. I think I'd better leave it to the professionals.

You could check with your town's building inspector. I know some towns have different requirements than others.

Using the flex hose isn't a good idea(and against local code AFAIK) since it doesn't have any insulating properties and could be a fire hazard. If it isn't in a mansonary chimney all other applications require L-vent because of fire protection.

When worried about height difference between stoves. Its best to do an up and out install. You could also do straight up through the roof too! This way if the next stove is a little shorter or taller you can use an adjustable section of pipe to get around it. Straight outs you will have to choose a similar height on the replacement stove's outlet location. Another is to build a hearth pad to set the stove on. You can adjust the hearth's height for the next stove.

Now if we could only get the stove manu. to standardize the outlet location there would be no worries.
 
While the flexible vent isn't allowed in this case, I believe there is a piece of adjustable hard pellet vent that can be. Now to find it.

You also need to understand that it isn't just the height that varies. So if you desire to have a pipe centered on the stoves, you'll likely run into that as an issue as well.

Simpson and Selkert have a 12" adjustable piece. Likely the others do as well.

everyone I know that makes PL pipe makes them there adjustable/telescoping pieces. If you (the OP) is concerned about not having any flexibility to change the stove out later then put in a small rise on the inside and use an adjustable in the process. that way you will already be prepared for the future.
 
Go up and out the roof then all you would have to fix would be a small piece of roof and a little bit of drywall which is much easier to fix than siding.
