Is there a way to direct air flow of my heat exchanger?

[Gargravarr]

I have a Lopi Leyden pellet stove that is sits at an angle on my hearth. This does a great job heating the center of the room, but the sides do not benefit well from the heat out put...

Are there any inserts I can buy that might direct 2 or 3 of the exchanger tubes on each side to direct the air flow off to the sides of the stove? (does this make sense?)

Thanks
