In a vertical installation where the vent pipe is visible in the room, if stove has it's appliance take-off located on the left or right side of the stove and you want to have the venting "centered" up the back of the stove, a clean-out tee may be used at a 45° angle off the back of the stove with a 45° elbow on top. The angled clean-out tee will off-set the installation left or right and the elbow will bring the venting back to center.
Off-set venting components such as elbows and clean-out tees have rotating sleeves at the bottom of each component so that venting can be locked together and spun to meet up with the next section of venting.
When adapting Pellet Vent Pro vent pipe into a flexible liner (masonry adapted installation), if you install a clean-out tee horizontally (instead of a 90° elbow), the clean-out cap can be removed to gain access to the liner for sweeping out the liner. This is much easier than taking the vent apart to clean or having to go up on the roof.
Every installation starts with an appliance adapter attached to the stove. From an aesthetic point of view, if you are doing a vertical install behind the stove, the install will look better if the venting can be as close to the stove as possible. Also, sometimes installations are "tight" with clearances and hearth pad restrictions. To help with these issues, Pellet Vent Pro offers venting components with adapters built-in. This keeps the venting close to the stove so the whole install can sit well on the center of the hearth and not have to reside out on the front edge. Component adapters include: 3PVP-X4AD (3" adapter to 4" increaser), 3PVP-TADX4 (3" clean-out tee with 3" adapter), 3PVP-T3AD (4" clean-out tee with 3" adapter)
When installing a wall thimble (3PVP-WT or 4PVP-WT), it's a good idea to have a length of vent pipe through the thimble before you fasten the thimble to the walls.
