Osburn 950 Wood Stove

The Osburn 950 Wood Stove is an EPA 2020 certified wood stove for 250 to 1,200 sq ft. It burns up to 5 hours on a load and takes a 6-inch chimney.

Who it's for

Right buyer. Owners of small homes, cabins, sunrooms, additions, finished basements, studio cottages, or one-room living spaces where wood-burning installation is permitted, roughly 250–900 sq ft, with reasonable insulation and access to seasoned hardwood at 15–20% moisture content.

The Osburn 950 shares the same SBI small-stove performance platform as the Enerzone Solution 1.4: same firebox volume, same heat output, same efficiency, same emissions, same 17-inch north-south log capacity.

How it performs

The 45,000 BTU/hr maximum is a peak rating, transient, achieved on dry cordwood at high loading density and short reload intervals. The figure that matters for daily life is the sustained output across a full burn cycle, which lands in the 12,000–27,000 BTU/hr band per the CSA B415.1-10 stack-loss method.

Good to know

• Same platform as the Enerzone Solution 1.4.
• Small firebox, short burns.
• The 1,200 sq ft figure is aspirational. The most consistent owner regret across small wood stoves is buying for the high end of the manufacturer's heating range.

Where it can go

The Osburn 950 is approved for installation in residential homes, cabins, sunrooms, alcoves (with double-wall pipe connector), and mobile or manufactured homes (with the required fresh-air intake kit and insulated intake pipe). It is not approved for installation in factory-built (prefab) metal fireplaces or in any outdoor or unconditioned space.

Clearances to combustibles

Floor protection

For the Osburn 950, the manual specifies no R-factor required for floor protection — only a continuous, non-combustible material. Approved materials include steel of at least 0.015" thickness, ceramic tiles sealed together with grout (over a continuous non-combustible sheet beneath), cement board, brick, or any other approved or listed material suited for floor protection. Tile alone is not sufficient — a continuous non-combustible sheet beneath the tile is required.

Floor protection dimensions per the manual: in Canada, 18 inches forward of the door opening and 8 inches each side; in the USA, 16 inches forward of the door opening and 8 inches each side. No floor protection is required if the stove is installed on a non-combustible floor (concrete slab, for example).

Clearances

United States figures, in inches. The rating plate on the appliance overrides any published number; the installer confirms on site.

Details

Warranty

A one-time replacement limit applies to all parts with lifetime coverage. Warranty is void if the unit is used to burn anything other than seasoned cordwood, or if it is not operated according to the owner's manual. Damage caused by misuse, improper installation, lack of maintenance, overfiring, downdrafts, venting problems, or under-estimated heating area is not covered. Improper installation by anyone other than an authorized qualified technician voids the warranty.

Warranty claims are made through your Osburn dealer and remain subject to SBI/Osburn inspection, approval, and the current written warranty. Kaminos is the retailer for this stove and supports buyers through purchase; final warranty approval rests with SBI as the manufacturer. SBI's parts network is well-stocked — replacement bricks, baffle, secondary tubes, glass, gaskets, and optional blower are openly available at fair prices through multiple parts vendors.

Osburn may require photos or returned parts to support a claim; repair work covered by warranty requires prior manufacturer approval.

Coverage details can change by component and warranty revision; the current Osburn warranty controls.

Other options

What arrives

• Osburn 950 wood stove with welded carbon-steel firebox and cast-iron glazed door
• Decorative side panels
• Stainless-steel heat shield over the C-Cast firestop
• Top heat deflector that redirects heat toward the front of the stove
• High-density refractory firebrick lining
• C-Cast baffle and stainless-steel secondary-air tube assembly
• Owner's manual and product documentation

Sold separately

• Code-compliant 6-inch chimney system — listed factory-built chimney for new installations, or an approved masonry chimney/liner configuration where permitted by code and verified by the installer/AHJ; required venting components are sold separately
• Single-wall or double-wall pipe connector between the stove and chimney — double-wall is required for alcove and mobile-home installations and reduces clearance requirements
• Hearth pad or floor protection sized to manual specifications, with continuous non-combustible sheet beneath any tile
• Optional 100 CFM blower with thermodisc heat sensor (SBI AC02023) — adds forced-air circulation to improve heat distribution; without it, heat moves by radiation and natural convection only
• Optional 5-inch fresh-air intake kit (SBI AC01421) — required for mobile-home installations and for code or mechanical-ventilation requirements
• 5-inch insulated flex pipe for fresh-air intake (SBI AC02090 or equivalent ULC S110 / UL 181 class 0 or class 1 insulated HVAC pipe) — required for mobile-home installations
• Optional 5-inch fresh-air intake register with airtight damper (SBI AC01349) — useful where local code, airtight-home design, or owner preference calls for a closable outside-air damper; do not close while the stove is in use
• Optional rigid fire screen (SBI AC01420) — not permitted for open-door use in the United States or in Canadian provinces/jurisdictions with particulate-emission limits; never permitted for use in a mobile home; never leave the stove unattended when used with a fire screen
• Optional heat shield AC02762 for further clearance reductions to 2 1/2" on rear, side, and corner measurements (subject to the door-handle 6" side-wall exception)

• Stove-top or flue thermometer — strongly recommended; not optional in practice
• Installation by an authorized qualified technician (WETT, NFI, or CSIA certified) — required for warranty coverage and often required by code, permit, or insurance

Installation

Chimney requirements from the specification sheet

The Osburn 950 performs best on a 6-inch chimney flue system. New factory-built chimney systems must comply with UL 103 HT (USA) or ULC S629 (Canada) and be suitable for solid fuel. The stove may also be connected to a code-compliant masonry chimney, provided the chimney has either a clay liner or a suitably listed stainless-steel liner and the application is verified by a qualified installer. Per the manual, minimum chimney height is 12 feet. The chimney must extend at least 3 feet above the highest point of contact with the roof and at least 2 feet above any roof line or obstacle within 10 feet horizontally, subject to local code and installer verification.

For mobile-home installations, single-wall pipe is strictly forbidden — only double-wall pipe is permitted, and a fresh-air intake kit with insulated intake pipe is required. The fresh-air intake pipe (HVAC type) must meet ULC S110 or UL 181 class 0 or class 1.

Outside air

An optional fresh-air intake kit is available for code jurisdictions requiring outside combustion air, for tight new-construction homes with mechanical ventilation, and is required for mobile-home installations. Use the AC01421 5-inch fresh-air intake kit for this stove. Mobile-home installations also require insulated 5-inch flex pipe such as AC02090 or equivalent ULC S110 / UL 181 class 0 or class 1 insulated HVAC pipe. The AC01349 airtight fresh-air intake register is an optional closable damper accessory for installations where local code, airtight-home design, or owner preference calls for one; do not close it while the stove is in use. A smoke detector and carbon monoxide detector are required in the room where the stove is installed.

Codes and approvals

Code compliance for any specific installation is determined by the local Authority Having Jurisdiction. Manufacturer listings cover what the stove is approved for; the AHJ approves what is permitted at your address. A WETT (Canada), NFI, or CSIA (USA) certified installer is strongly recommended and frequently required by code, permit, or insurance. Confirm local requirements before purchasing — particularly in EPA non-attainment counties and in HOA jurisdictions where new wood-burning installs may be restricted.

Planning the install

• Check with your building department and insurer: wood appliances need a permit in most places and an inspection after installation.
• The chimney is the other half of the system. It is sold separately and quoted from your installer's plan.
• Clearances and floor protection come from the manual and depend on the pipe and shields you choose. Send us your plan and we will check it.
• Burn seasoned wood below 20 percent moisture. Wet wood is the cause of most complaints about any wood stove.
• Special-order goods ship by freight.
