Step 1: Preparation – Floor & Wall Protection

Choosing Floor Protection

• Check your stove’s manufacturer instructions.
• Most stoves require Type 2 thermal protection if placed on combustible flooring.
• Ensure 16” clearance in front and 8” on each side (per UL 1482 standards).
• Use a hearth pad or stove board for adequate protection.

Wall Protection

• Follow clearance instructions from the stove manufacturer.
• If needed, install non-combustible hearth pad wall protection with 1” spacers for ventilation.
• This can reduce required clearance by up to 66%.

---

Step 2: Cutting the Ceiling & Roof Holes

• Use a plumb bob or laser level to align the stovepipe’s center point.
• Cut the ceiling hole according to your chimney pipe’s size specifications.
• Continue this cut through all floors until reaching the roof.

---

Step 3: Insulation & Chimney Support

• Remove insulation around the chimney path.
• Install a ceiling support box to support the weight of the chimney.
• For multi-story homes, install firestop joist shields at each level.
• If passing through an attic, use an attic insulation shield or build a chase.

---

Step 4: Installing Roof Flashing

• Cut a hole in the roof, making it oval-shaped for pitched roofs.
• Remove nails from under shingles to slide the flashing underneath.
• Apply high-temp silicone under the flashing for waterproofing.

---

Step 5: Assembling the Chimney

 

• Start assembling from the ceiling support box upwards.
• Use Class A insulated chimney pipe with screws to secure sections.
• Ensure the chimney extends at least 3 feet above the roof and 2 feet above any structure within 10 feet.
• Use wall standoffs every 8 feet for stability.
• If the chimney extends over 5 feet, install a roof brace kit.

---

Step 6: Installing the Stove Pipe

• Use single-wall or double-wall pipe, depending on clearance needs.
• Single-wall pipe needs 18” clearance, while double-wall needs 6”.
• Ensure the male end of each pipe points downward.
• Use telescoping pipes for easier installation.

---

Step 7: Installing a Damper

• If your stove lacks built-in draft control, install a stovepipe damper.
• This regulates airflow, maximizing burn efficiency.
• Drill holes in the stovepipe to insert and secure the damper.

---

Step 8: Testing Your Stove

• Light 3–4 small fires to cure the firebricks and paint.
• Ensure smoke is properly vented without rolling into the room.
• If smoke enters the room, check clearances and pipe connections.

Key Considerations Before Installing

Choosing the Right Stove

• EPA-rated stoves maximize heating efficiency.
• Choose the stove size based on your room size, not home size.
• Osburn wood stoves offer secondary air burn technology for efficiency.

Building Codes & Regulations

• Always follow local and national codes.
• Chimney pipe should be UL 103 HT listed.
• Maintain proper stove and chimney clearance.

Should You Hire a Professional?

4. What’s the difference between single-wall and double-wall stove pipe?

Single-wall pipe requires 18” clearance, while double-wall pipe needs only 6” clearance.

 

5. How do I prevent smoke from entering my home?

Ensure your chimney is properly installed, follows clearance guidelines, and is drafting correctly.

 

6. How often should I clean my chimney?

At least once per year, or more frequently if you burn wood daily.

 

7. Can I vent a wood stove horizontally?

No, a wood stove must be vented vertically to allow proper draft.

 

8. Is a damper necessary?

Newer EPA-certified stoves have built-in dampers, but older models may require a manual stovepipe damper.
