The pellet stove gets all the attention on the quote, but the venting is where budgets drift. A stove that costs a few thousand dollars can need anything from a few hundred dollars of pipe to well over a thousand, depending on where the vent leaves the house.
This guide prices the four most common pellet vent installs using real parts from our Ventis PelletVent range, explains what pushes the cost up, and covers what to expect on labor. If you are still working out which type of pipe you need, start with our guide to which venting your stove actually needs.
The short answer
- Straight out the wall: about $480 in parts
- Out the wall with a vertical rise outside: about $870 in parts
- Up through the ceiling and roof, 3-inch: about $970 in parts
- Up through the ceiling and roof, 4-inch: about $1,120 in parts
- Labor: a few hundred dollars for a simple wall exit, more for a roof or chimney job
All parts prices below are our current prices for Ventis PelletVent as of October 2026, in the galvanized finish. Every install is different, so treat these as worked examples, not quotes. Your stove's installation manual has the final say on what the run must include.
Install 1: straight out the wall (about $477)
This is the shortest and cheapest pellet vent run there is. The vent leaves the back of the stove, passes straight through an exterior wall and ends in a cap a short distance outside. It only works where your stove's manual allows a horizontal termination with no vertical rise, and where the cap can meet the required clearances from windows, doors, decks and the ground.
- Stove adaptor tee with clean-out cap (VP-SAT03): $186
- 12-inch pipe section (VP-0312): $69
- Wall pass-thru (VP-WPT03): $126
- Horizontal rain cap (VP-HC03): $96
Total: $477. The tee at the stove outlet matters more than it looks. Fly ash collects at the bottom of the run, and the clean-out cap is how you get it out each season.
Install 2: out the wall with a vertical rise (about $868)
Most pellet stove manufacturers recommend some vertical pipe after the vent leaves the stove. If the power cuts out mid-burn, the combustion blower stops, and a vertical section lets the remaining smoke rise and draft naturally instead of drifting back into the room. A common way to get that rise is to exit through the wall, turn upward with a tee on the outside of the house, and run a few feet of pipe up the exterior wall.
- Stove adaptor tee with cap (VP-SAT03): $186
- 12-inch pipe through the wall (VP-0312): $69
- Wall pass-thru (VP-WPT03): $126
- Outside tee with clean-out cap (VP-T03): $184
- 36-inch pipe for the rise (VP-0336): $121
- Wall support bracket (VP-WS03): $52
- Vertical rain cap (VP-VC03): $130
Total: $868. Taller rises need extra pipe and additional wall straps, which is the only real variable here.
Install 3: up through the ceiling and roof, 3-inch (about $971)
A vertical run inside the house keeps the vent warm, drafts well and leaves nothing on the outside wall. It costs more because it needs more pipe and has to pass through a ceiling and a roof. This example assumes a single-story home with about 11 feet of pipe from the stove to above the roofline.
- Stove adaptor (VP-SA03): $54
- Tee with clean-out cap (VP-T03): $184
- 2 x 48-inch pipe (VP-0348): $294
- 36-inch pipe (VP-0336): $121
- Ceiling firestop (VP-FS03): $101
- Roof flashing, 0/12 to 6/12 pitch (VP-F0306): $58
- Storm collar (VP-SC03): $29
- Vertical rain cap (VP-VC03): $130
Total: $971. A steeper roof needs the 6/12 to 12/12 flashing instead. If the pipe runs through an insulated attic, add an attic insulation shield, and a long section above the roof may need a roof brace.
Install 4: through the ceiling and roof, 4-inch (about $1,116)
Longer runs, extra elbows and higher altitudes can push you past the length your stove allows on 3-inch pipe. When that happens, the manual will call for 4-inch. Most pellet stoves still have a 3-inch outlet, so the run starts with a 4-inch to 3-inch adaptor tee. This example covers about 11 feet of pipe through a ceiling and roof.
- 4-inch to 3-inch stove adaptor tee (VP-SAT43): $212
- 2 x 48-inch pipe (VP-0448): $320
- 36-inch pipe (VP-0436): $149
- Ceiling firestop (VP-FS04): $127
- Attic insulation shield (VP-AIS04): $100
- Roof flashing (VP-F0406): $61
- Storm collar (VP-SC04): $32
- Vertical rain cap (VP-VC04): $115
Total: $1,116. Stepping up to 4-inch adds roughly 15 to 20 percent to the parts cost of a vertical run. That is far cheaper than living with an undersized vent that soots up and trips the stove's safety shutdowns.
What pushes the cost up
- Elbows. Each 90-degree elbow costs $134 in 3-inch and adds several feet to your equivalent vent length. Routing around an obstacle with two or three of them can cost more than the straight pipe, and may push you to 4-inch.
- Black finish. Painted black pipe looks better in a living room, but it costs more. A 36-inch length is $135 in black against $121 galvanized. Many installs use black for the visible section indoors and galvanized everywhere else.
- Fresh air intake. Tight modern homes and mobile homes often need outside combustion air. A fresh air intake kit is $132, or a combined wall pass-thru with fresh air intake handles both in one wall opening.
- Second stories. Every extra floor adds pipe, a firestop and labor.
- Existing chimneys. Venting a pellet insert up a masonry chimney needs a masonry adaptor ($165) plus a liner running the full height of the flue, and the chimney should be inspected first. It is often the most expensive route, even though the chimney already exists.
What labor costs
Installer pricing varies a lot by region, but the pattern is consistent. A straight through-the-wall job is the cheapest to have fitted, often a few hundred dollars and under half a day's work. Roof penetrations cost more because they involve cutting and flashing the roof, working in the attic and spending longer on site. Chimney relines and second-story runs sit at the top of the range.
When you compare quotes, check whether the price includes the venting parts, the floor protection pad, the permit and the first start-up. Some quotes are labor-only, and others bundle everything.
The simplest installs are within reach of a capable DIYer. Anything that goes through a roof or into an existing chimney is worth paying a professional for, and many areas require a permit and inspection either way.
How to keep the cost down
- Plan the shortest route your stove's manual allows, with as few elbows as possible
- Place the stove near an exterior wall if a wall exit is an option
- Use black pipe only where it will be seen
- Buy the whole run in one order so every part comes from the same Ventis system
- Have the run checked against the manual before anything is cut
REMEMBER
Your local authority having jurisdiction may enforce building codes that differ from the manufacturer's instructions. Confirm the requirements in your area, follow your stove's installation manual for clearances and termination locations, and use a qualified installer for any work you are not comfortable doing yourself.
If you send us your stove model and a sketch or photos of where the vent needs to go, we will put together the parts list and check it against the manual before you order. Browse the full range of pellet vent pipe and components.
