Chinook Wood Stove for Homes and Shops

The Chinook Wood Stove by Flame Innovation is a heavy-duty, high-efficiency wood stove designed to provide dependable heat for homes, garages, workshops, and shops.

Built in Post Falls, Idaho, the Chinook combines American-made construction with a large brick-lined firebox, strong heating performance, catalytic and secondary combustion, and patented airflow technology.

With heating capacity for spaces up to approximately 2,400 square feet, an EPA-tested maximum heat output of 36,400 BTU per hour, and an estimated maximum output of up to 80,000 BTU per hour, the Chinook is built for serious heating—not lightweight recreational use.

Its patented Variable Choked Venturi technology helps regulate combustion air as chimney draft changes. This gives the Chinook an additional level of automatic airflow control while preserving the straightforward operation and dependable construction expected from a traditional wood stove.

A Serious Wood Stove for Homes and Shops

The Chinook is designed for permanent heating applications where reliability, output, efficiency, and durability matter.

Unlike smaller stoves intended primarily for tents, sheds, tiny homes, or occasional recreational use, the Chinook has the firebox capacity and heavy-duty construction needed for larger residential and working spaces.

The Chinook is well suited for:

• Primary or supplemental home heating
• Garages
• Workshops
• Detached shops
• Rural properties
• Manufactured and mobile homes when properly installed
• Buildings that need dependable backup heat
• Areas where winter power outages are common

Its 2.17-cubic-foot firebox accommodates properly split firewood up to 18 inches long, allowing homeowners and shop owners to use standard-length firewood without constantly cutting unusually short pieces.

Why the Chinook Is an Excellent Wood Stove for Home Heating

A home-heating stove needs to provide more than occasional warmth. It must be capable of producing steady heat, operating efficiently, and withstanding repeated use throughout the heating season.

The Chinook is built to meet those demands.

Heating Capacity for Larger Spaces

The Chinook can heat spaces up to approximately 2,400 square feet under suitable conditions.

Actual heating capacity will depend on:

• Outdoor temperature
• Home insulation
• Ceiling height
• Floor plan
• Air leakage
• Chimney configuration
• Firewood species
• Firewood moisture content
• Amount of wood loaded

The Chinook’s broad heat-output range allows it to provide lower, sustained heat during mild conditions and significantly greater output when colder weather demands it.

Dependable Heat During Power Outages

The Chinook does not require electricity to operate its combustion system.

This allows it to continue producing heat during power outages when furnaces, heat pumps, and other electrically dependent heating systems may not function.

An optional fan is available to improve room-air circulation, but the stove itself can continue operating without it.

Large Fire-Viewing Window

The Chinook features a large neo-ceramic glass window measuring approximately 16⅜ inches wide by 11¼ inches tall.

The viewing window provides a clear view of the fire while allowing radiant heat to enter the living space. It also gives the Chinook a more refined residential appearance without sacrificing its rugged construction.

Outside Combustion-Air Connection

A 4-inch outside-air connection allows combustion air to be supplied from outside the building.

Outside combustion air can be especially valuable in tightly sealed homes or buildings affected by exhaust fans and other appliances that may influence indoor air pressure.

Why the Chinook Is Built for Garages, Workshops, and Shops

Garages and shops can be more difficult to heat than residential rooms. They often have higher ceilings, concrete floors, large overhead doors, open floor plans, and greater heat loss.

The Chinook is built for these demanding heating environments.

Heavy-Duty Construction

At approximately 480 pounds, the Chinook is a substantial heating appliance.

Its heavy-gauge steel body, fully brick-lined firebox, stainless steel secondary burn tubes, catalytic combustion system, and protected baffle assembly are designed for long-term use.

This rugged construction makes the Chinook an excellent choice for shops and working spaces where durability is just as important as heat output.

Strong Heat Output

The Chinook has an EPA-tested maximum heat output of 36,400 BTU per hour.

Under higher real-world fuel-loading conditions, the stove has an estimated maximum output of up to approximately 80,000 BTU per hour.

The estimated output will vary depending on:

• Type of wood
• Wood density
• Log size
• Firewood moisture content
• Amount of wood loaded
• Chimney draft
• Burn setting
• Installation conditions

For comparisons with other certified wood stoves, the EPA-tested output of 36,400 BTU per hour should be used. The estimated 80,000 BTU maximum represents the stove’s potential under higher real-world fuel loads and is not an EPA-certified rating.

Optional Heat-Circulation Fan

An optional 165 CFM double squirrel-cage fan can help distribute heated air throughout larger rooms and open workspaces.

The fan can reduce the temperature difference between the area immediately surrounding the stove and more distant sections of the building.

The fan is optional and does not control the stove’s combustion system.

Large Firebox for Practical Home and Shop Heating

The Chinook features a fully brick-lined 2.17-cubic-foot firebox that measures approximately 16 inches wide by 21 inches deep.

It accommodates properly split logs up to 18 inches long, making it practical for homeowners and shop owners who use standard cordwood.

The refractory firebrick helps retain heat inside the firebox and protects the steel body from direct exposure to the highest combustion temperatures.

A larger firebox also provides greater flexibility in fuel loading and heat output. The amount, size, type, and moisture content of the wood can all affect the amount of heat produced.

High-Efficiency Catalytic and Secondary Combustion

The Chinook uses both secondary and catalytic combustion to extract more usable heat from the wood and reduce particulate emissions.

Its combustion system includes:

• Five stainless steel secondary burn tubes
• A catalytic combustor
• A stainless steel catalyst protector
• A high-temperature baffle board
• KAO wool insulation
• A fully brick-lined firebox
• Controlled primary and secondary combustion air

The secondary burn tubes introduce heated air above the fire, helping ignite smoke and combustible wood gases that might otherwise escape through the chimney.

The catalytic combustor supports additional combustion and helps reduce particulate emissions while recovering more heat from the fuel.

EPA-Certified Performance

The Chinook provides strong heating performance while meeting modern emissions requirements.

Tested Performance

• EPA-tested maximum heat output: 36,400 BTU per hour
• Estimated maximum real-world output: Up to approximately 80,000 BTU per hour
• Heating capacity: Up to approximately 2,400 square feet
• EPA-certified particulate emissions: 1.29 grams per hour
• Overall efficiency: 79.4% HHV
• Overall efficiency: 84.9% LHV
• Firebox capacity: 2.17 cubic feet
• Maximum recommended log length: 18 inches

Actual performance depends on the installation, chimney, building, operating conditions, and firewood being used.

What Sets the Chinook Apart From Traditional Wood Stoves?

The Chinook provides the size, construction, and heating capacity customers expect from a serious home or shop wood stove.

What sets it apart is its patented Variable Choked Venturi airflow system.

Traditional wood stoves rely largely on the operator to adjust combustion air as the fire, stove temperature, chimney temperature, and outdoor conditions change.

Chimney draft does not remain constant. It becomes stronger as the chimney heats and can change with outdoor temperature, wind, chimney height, and the stage of the burn.

The Chinook’s VCV technology responds mechanically to those changing draft conditions.

Some advanced wood stoves use electronic sensors, control boards, motors, and powered dampers to make combustion-air adjustments. The Chinook performs a similar airflow-management function through mechanical engineering.

VCV technology is not the reason the Chinook is a home and shop stove. Its heating capacity, firebox, durability, and construction establish that. VCV technology is the added feature that helps the Chinook manage combustion more effectively than a conventional manually controlled stove.

Primary VCV Control During Low-to-Medium Burns

The Primary VCV operates during low-to-medium burn settings.

As chimney draft pressure changes, the Primary VCV helps regulate the primary air supplied directly to the wood.

When chimney draft becomes stronger, the valve reduces primary airflow to help prevent an overly aggressive fire from consuming the wood too quickly.

As chimney draft decreases, the valve allows additional primary air to help sustain combustion.

This helps the stove respond to changing chimney conditions without requiring the operator to continually compensate with repeated manual adjustments.

Full High-Burn Operation

During a full high burn, the manual primary air control overrides the Primary VCV.

This allows the greater airflow required for maximum combustion and heat output.

The Primary VCV therefore helps regulate combustion during low-to-medium burns without restricting the stove when full high-burn performance is needed.

Secondary VCV Controlled by Chimney Draft Pressure

The Secondary VCV is controlled entirely by chimney draft pressure.

It automatically regulates the air supplied to the stove’s five stainless steel secondary burn tubes.

As chimney draft changes, the Secondary VCV adjusts the secondary airflow to better match the stove’s combustion conditions.

This supports the combustion of smoke and unburned wood gases above the fire without requiring electronic sensors, electric motors, or operator adjustment.

The Secondary VCV continues responding to chimney draft pressure during low, medium, and high-burn operation.

How the Chinook Operates at Different Burn Settings

Low Burn

During a low burn, the Primary VCV helps regulate primary combustion air based on chimney draft. The Secondary VCV independently controls secondary airflow through chimney draft pressure.

Medium Burn

During a medium burn, the Primary VCV continues helping manage primary airflow while the Secondary VCV automatically controls air supplied to the secondary combustion tubes.

Full High Burn

During a full high burn, the manual primary air control overrides the Primary VCV to provide increased primary airflow.

The Secondary VCV continues operating automatically based on chimney draft pressure.

This design gives the operator control over the desired heat setting while allowing the stove to respond mechanically to changing chimney conditions.
