Osburn 2000 Wood Stove

The Osburn 2000 Wood Stove is an EPA 2020 certified wood stove for 500 to 2,100 sq ft. It burns up to 8 hours on a load and takes a 6-inch chimney.

Who it's for

Right buyer. Owners of medium-to-larger homes, well-insulated open-plan two-story spaces, or one stove serving as primary winter heat across 1,200–1,800 sq ft of conditioned space, with reasonable insulation and access to seasoned hardwood at 15–20% moisture content.

Buyers stepping up from the Osburn 1700 medium-stove platform who want a meaningful firebox jump, longer 20-inch logs, and longer burn cycles.

How it performs

The 75,000 BTU/hr maximum is a peak rating, transient, achieved on dry cordwood at high loading density and short reload intervals.

Good to know

• Same platform as the Enerzone Solution 2.3.
• Medium-large firebox, medium-long burn time. A 2.4 ft³ non-cat stove gives you meaningful primary-heat capability across 1,200–1,800 sq ft, with realistic 6–7 hour burn cycles.
• The 2,100 sq ft figure is aspirational. The most consistent owner regret across medium-large stoves is buying for the high end of the manufacturer's heating range.

Where it can go

The Osburn 2000 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 2000, 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. In Canada, the manual also requires ember protection extending at least 18 inches in front of any door and 8 inches on other sides per CSA B365. 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 blower components 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.

What arrives

• Osburn 2000 wood stove (OB02015) with welded carbon-steel firebox and arched cast-iron glazed door

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 thermodisc heat sensor — automatic on/off control for the included blower based on stove temperature
• Optional ash lip glass panel — visible glass strip at the door opening

• 5-inch insulated flex pipe for fresh-air intake (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 — 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

Installation

Chimney requirements from the specification sheet

The Osburn 2000 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. Minimum chimney height must follow the current manual, certification label, installer verification, and local code. 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. Mobile-home installations also require insulated 5-inch flex pipe (ULC S110 / UL 181 class 0 or class 1 insulated HVAC pipe). 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.

California Proposition 65

This product can expose you to chemicals including carbon monoxide, which is known to the State of California to cause cancer, birth defects or other reproductive harm. For more information go to www.P65warnings.ca.gov.

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.
