Assembly Instructions For
3" Simpson Pellet Vent PRO Horizontal Kit, #3PVP-KHA
The pellet venting we sell is Dura-Vent Pellet Vent Pro. Pellet Vent Pro is a twist-lock pellet vent that has an integrated silicon seal within the vent. Simpson Dura-Vent, the pellet venting available in home stores like Home Depot and Lowe's (and we do not sell) is a lower grade pellet venting without the integrated silicon seal. THESE VENTING TYPES ARE MADE BY THE SAME MANUFACTURER BUT THEY CANNOT BE USED TOGETHER AND ARE NOT COMPATIBLE.
General Installation Instructions:
- Place your stove where it is going to be. If your stove requires a hearth pad, make sure the stove is on it.
- Attach your appliance adapter to the stove using the included RTV sealant and at least 1 screw to the collar.
- If you are going up inside the house, attach your clean out T and then build your venting upwards, attach your 90° Elbow and then mark the center point. Mark the center point where the venting meets the wall.
- Using a drill bit that is longer than the depth of the wall, drill your center hole in the wall to the outside.
- The black side of the thimble is the inner section and the galvanized is the exterior section. Using the black half of the thimble, trace it's annular tube at the center point where your hole is. This will be the line for removing the section of the wall. Do the same on the exterior of the wall with the galvanized half of the thimble.
- Attach both halves the the thimble together through the wall.
- Slide your straight length of pipe through the wall thimbles and attach it to the appliance adapter.
- If you are creating your vertical rise on the exterior, just start attaching your venting to find the wall pass-through point, this is where you will cut your hole for the wall thimble. You will attach your clean out T to the venting outside.
- Secure your wall thimble to the wall with screws. Always use exterior rated screws for the outside connection to avoid rust marks from developing.
- Attach your horizontal cap to the end of the venting.
