Customer Questions
What size wood insert is right for my home?
Choosing the right size wood insert depends on both your heating needs and the dimensions of your existing fireplace. Be sure to measure your fireplace’s width, height, and depth, then compare those to the minimum fireplace dimensions listed on each product page to ensure a proper fit. Generally, small inserts heat up to 1,500 sq. ft., medium inserts cover up to 2,500 sq. ft., and large inserts can heat areas larger than 2,500 sq. ft., though actual performance varies based on factors like firewood type, room layout, ceiling height, and insulation.
Do I need a chimney liner for my wood stove or fireplace insert?
A stainless steel chimney liner kit is always recommended when installing a wood-burning fireplace insert or freestanding stove in a masonry chimney. The liner ensures a consistent and safe flow of exhaust gases, improving the draft and overall efficiency of your appliance while protecting your chimney from heat and corrosion. Using a chimney liner helps maintain safety and enhances stove performance.
Do any wood inserts qualify for a federal tax credit?
Yes, wood-burning inserts that meet government efficiency standards and qualify for the 30% federal tax credit are clearly marked at the top of each product description on HVACDirect.com. You can also view all qualifying models in one place at https://hvacdirect.com/stoves/tax-credit-stoves.html to find the best option for your home.
What is a faceplate or surround for a fireplace insert?
A faceplate, surround, or trim kit is used with fireplace inserts to cover and close the gap between the insert and the fireplace opening. It helps create a clean, finished look while ensuring a proper fit, and should be sized slightly larger than your fireplace’s width and height. Various sizes are available to match common fireplace openings for a seamless installation.
Do I need a blower for my fireplace insert?
A blower is a great addition to a fireplace insert that helps boost heat output and improves efficiency by circulating warm air more effectively throughout your room. While most inserts can operate without a blower, adding one is beneficial if you want faster, more even heating. If extra heat isn’t necessary, your insert will still work well without a blower.
Can an Osburn Matrix 1900 Wood Burning Fireplace Insert with Blower be installed in a wood framed cavity? I am looking to replace a gas fireplace that uses a 6" gas vent pipe.
    The Osburn 1900 Matrix Insert must be installed into an existing fireplace opening with a masonry chimney. It cannot be installed into a wood framed space. Please give us a call if we can help further. Thanks!    
When you mention in the answer regarding the "wood framed space." How can we check if it's a wood framed space? The exterior face of the fireplace is brick, but the walls around it are drywall.
    The Osburn 1900 Wood Insert must be installed into an existing masonry wood burning fireplace constructed of brick and mortar. It cannot be installed into a factory built metal fireplace. It cannot be installed in a wood framed space constructed in new builds and remodels to house a factory built metal fireplace. Please give us a call if we can clarify further and have pictures available if possible. Thanks!
