Can the 3 inch wall thimble air intake kit be used with an exhaust that vents straight out (see the attached example), or does it have to have a vertical pipe on the exterior side? How far from the exhaust does the intake have to be? I currently have a pipe that is vertical, but we moved the location of our stove to the front of my house and do not want a vertical chimney, if possible.

Answer:This product can indeed be used with a completely horizontal pipe application. However, please keep in mind this product is intended for 3 inch PelletVent Pro, which actually has an O.D. of 3 5/8 inches. The air intake should be at least 12 inches from the termination, unless the manufacturer of the stove specifies that it can be closer.
