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.

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.
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.
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.

Hands down the best experience we’ve had with a company doing work on our home. We found them through an internet search, looking for quotes for a complete chimney overhaul. From the first phone call to the day, they completed the work, everyone we talked to was professional, knowledgeable, and friendly! Yup, they were all nice people! We noticed a small issue after they were finished. Within 24 hours, the owner had been out to look at it and a technician was sent out to correct the problem. And they were, again, nice, and completely understanding about it. We couldn’t be happier with the result. We highly recommend ACS to everyone!
We had to have a rebuild done on our chimney. They were very professional and worked hard. What a wonderful job they did! They took away all the old bricks and cleaned them up after they were done. Our chimney looks fantastic. The pricing was very affordable. Thank you, Affordable Chimney!
Brandon, the Affordable Chimney Sweeps technician, inspected my chimney and found a dangerous problem that had been missed by another company’s inspector. As a result, I contracted to have Affordable replace the chimney liners and do other repairs to both the fireplace and heating exhaust systems. Their quoted price was 20% lower than the others. The estimated time for the work was 2.5 days. They came in on time and worked hard without breaks until the rain started late in the afternoon. They came back the next day and surprisingly finished in a couple of hours. They worked hard, they were courteous, and they answered all my questions. They cleaned up carefully. They earned their 5 stars.
