Product Details:

The Ventis HEI170 Wood Burning Fireplace Insert is a great option to update any old and inefficient fireplace. The large glass door allows you to fully enjoy the beauty of the fire while cozying up next to it in the cold winter months. The HEI170 is a medium size insert that is capable of heating up to 1,800 square feet while producing up to 65,000 BTUs. The 1.9 cubic ft firebox can hold up to an 18" log. The clean burning non-catalytic insert is EPA approved with a low 1.26 g/h emissions rating.

The Ventis HEI170 firebox is fully lined with firebrick which can have up to an 8 hour burn time on one load of wood. Choose between a 29" x 44" regular or the 34" x 50" large faceplate to give the seal around the fireplace opening and insert a finished look. The clean and modern design will fit with any decor and be the focal point of the room. The Ventis HEI170 comes standard with a 144 CFM blower to help push the warmth across the room.

    Required Accessory:


    The Faceplate is the component that flashes around the fireplace insert and covers the fireplace. The Faceplate for the HEI170 insert is available in two sizes: 29" x 44" and 34" x 50". The size you choose should be based on the opening of your existing fireplace. Choose the 29" x 44" Faceplate size if the opening of your fireplace is less than 29" x 44". If your fireplace opening is greater than 29" x 44", you will want to select the 34" x 50" Faceplate size.

    Optional Accessory:

    Rigid Firescreen

    The Rigid Fire Screen allows you to burn wood in the fireplace insert with the door open just like an old-time fireplace. Hear the crackle of the wood, watch the flames dance around in the firebox and relax around the wood insert on a cold winter's night. The Rigid Fire Screen is easy to install and easy to remove when you are ready to load more wood. The fireplace insert should not be burning with the door open without the firescreen.

    Optional Chimney Liner Kit

    Rock-Flex 316Ti stainless steel chimney liner kits are UL listed and the perfect choice to install for your new wood burning insert. Each kit includes the 316Ti Flexible Chimney Liner, Vertical Appliance Connector, 13 x 13 in. Premium Top Plate, and Round Rain Cap.
