This guide walks you through every step, the parts you need, and the safety codes that apply.
Are Wood Stoves Allowed in Mobile Homes and Trailers?
Yes, but strict rules apply. The U.S. Department of Housing and Urban Development (HUD) sets the baseline under 24 CFR Part 3280. Most states follow these federal standards, and NFPA 211 (Standard for Chimneys, Fireplaces, Vents, and Solid Fuel-Burning Appliances) applies as the main installation reference. Always check with your local code authority or fire marshal before you start.
HUD requires the following for any wood stove in a manufactured or mobile home:
- The stove must carry a UL 1482 listing or HUD label confirming it is approved for mobile home use.
- The stove must be permanently bolted to the floor to prevent movement during transit or vibrations.
- You must supply outside combustion air directly to the firebox - room air is not allowed.
- You must use a Class A insulated chimney system for any wall, ceiling, or roof penetration.
- A spark arrestor or chimney cap is required on top of the chimney.

|---|---|---|
| Mobile-home-approved wood stove | Heat source | Must carry UL 1482 or HUD label |

| Class A chimney pipe | Passes through ceiling, attic, roof, or wall | UL 103 HT listed, 2 inch clearance |
| Ceiling support box or wall thimble | Transition from stove pipe to Class A | Maintains required clearances |
| Roof flashing and storm collar | Weatherproofs the roof penetration | Must match roof pitch |
| Chimney cap with spark arrestor | Keeps rain out, stops sparks | Required by HUD |
| Fresh air intake kit | Supplies outside combustion air to stove | Mandatory per HUD |
| Non-combustible hearth pad | Protects the floor under and around stove | Min 18" front, 8" sides |
| Heat shield | Reduces wall clearance if stove is near a wall | Per stove manufacturer specs |

Step-by-Step: How to Install a Wood Stove in a Mobile Home
1. Choose a Certified Stove
The stove must be listed as "Approved for Use in Mobile Homes or Manufactured Housing." Look for the UL 1482 mark or HUD compliance label on the data plate. Using an uncertified stove in a mobile home is a code violation and a serious fire risk.
2. Plan the Layout
- Keep the stove at least 36 inches from any combustible surface unless a heat shield reduces that clearance (check your stove's manual for reduced clearance distances).
- Use a hearth pad that extends at least 18 inches in front and 8 inches on each side of the stove.
- Plan a straight chimney run whenever possible - either vertically through the roof or horizontally through an exterior wall and then up. Fewer bends mean better draft and easier cleaning.
For help planning the best route, see our guide on installing a chimney through the attic or running a chimney along an outside wall.
3. Install the Fresh Air Intake
Connect the outside air kit directly to the stove's combustion air inlet, usually via a duct through the floor or exterior wall. This supplies the fire with outdoor air instead of pulling heated air from the room. HUD makes this mandatory for manufactured housing because mobile homes are built much tighter than site-built houses, and pulling room air can cause negative pressure, backdrafting, and carbon monoxide buildup.
4. Install the Stove Pipe and Chimney System
Use double-wall stove pipe inside the room to connect the stove to the chimney entry point. Double-wall stove pipe requires 6 inches of clearance to combustibles. Stove pipe stays inside the room only - it never passes through a wall, ceiling, or floor.
At the ceiling or wall penetration, transition to Class A insulated chimney pipe. Class A pipe is UL 103 HT listed, rated to 2,100 degrees F, and requires only 2 inches of clearance to combustibles. This is the only pipe type allowed to pass through structural elements.
For a roof exit: Cut the ceiling opening to match the ceiling support box dimensions. Install the support box, then stack Class A chimney sections vertically through the attic and roof. Add roof flashing, storm collar, and a chimney cap with spark arrestor on top. The chimney must extend at least 3 feet above the roof penetration point and 2 feet higher than any part of the roof within 10 feet (the 3-2-10 rule per NFPA 211).
For a wall exit: Install a wall thimble kit to pass through the exterior wall, then run Class A chimney pipe vertically up the outside of the mobile home. Use wall support brackets every 5 to 6 feet to secure the pipe. The chimney must still meet the 3-2-10 height rule.
5. Anchor the Stove to the Floor
Use lag bolts or manufacturer-supplied brackets to fasten the stove securely to the subfloor. This prevents the stove from shifting during travel (if the home is moved) or from vibrations. HUD requires permanent floor attachment for all solid-fuel appliances in manufactured housing.
6. Final Safety Checks
- Install a carbon monoxide (CO) alarm and a smoke detector in the same room as the stove.
- Place a Class A fire extinguisher nearby and easily accessible.
- Light small break-in fires first to cure the stove paint and check every joint for smoke leaks.
- Verify all clearances one more time before regular use.
Mobile Home vs. Site-Built Home: Key Differences
| Factor | Mobile Home / Trailer | Site-Built Home |
|---|---|---|
| Governing code | HUD (24 CFR 3280) + NFPA 211 | IRC / local building code + NFPA 211 |
| Stove certification | UL 1482 or HUD label required | EPA certified (any UL listed stove) |
| Outside combustion air | Mandatory | Often recommended, not always required |
| Floor anchoring | Required (bolted to subfloor) | Not typically required |
| Chimney type | Class A only (UL 103 HT) | Class A or masonry chimney |
| Spark arrestor | Required by HUD | Required in some jurisdictions |
Ongoing Maintenance and Safety Tips
- Burn only seasoned hardwood with moisture content below 20%. Wet wood creates more creosote and increases chimney fire risk.
- Never burn garbage, treated lumber, or painted wood - these release toxic fumes and corrosive chemicals that damage your chimney liner.
- Inspect your chimney system at least once a year. For mobile homes, the tighter construction makes regular inspection even more important. See our guide on how to clean your chimney.
- Clean the chimney pipe and stove pipe whenever you see 1/8 inch or more of creosote buildup.
- Test your CO alarm monthly and replace batteries at least once a year.

Frequently Asked Questions
Can I use a regular wood stove in a mobile home?
No. Federal HUD regulations require a stove that carries a UL 1482 listing or HUD compliance label specifically for use in mobile homes and manufactured housing. A standard EPA-certified wood stove does not meet this requirement, even if it is safe in a site-built home.
Do I need a permit to install a wood stove in a mobile home?
In most areas, yes. Contact your local building department or fire marshal before you begin. Some jurisdictions require a permit, an inspection, or both. Your homeowner's insurance company may also need to be notified.
Why is outside combustion air required in a mobile home?
Mobile homes and trailers are built much tighter than traditional houses. Without a dedicated outside air supply, the stove pulls air from inside the home, creating negative pressure. This can cause backdrafting, where exhaust gases (including carbon monoxide) get pulled back into the living space instead of going up the chimney.
Can I install a chimney liner instead of Class A pipe in a mobile home?
No. Chimney liners are designed to reline existing masonry chimneys. Mobile homes do not have masonry chimneys, so you need a Class A insulated chimney pipe system that is UL 103 HT listed with 2 inches of clearance to combustibles.
How tall does the chimney need to be on a mobile home?
Per NFPA 211 and the 3-2-10 rule: the chimney must extend at least 3 feet above the point where it exits the roof and at least 2 feet higher than anything within 10 feet (roof ridge, nearby structures, trees). Read more in our guide on required chimney height above the roof.
