Custom Venting Kits

Let Us Help You Configure Your Chimney!

Need help with your installation? Every chimney configuration is different and depends upon your application and the design of your home.

For a quote on your custom venting kit, kindly email your interior/exterior digital photos to vanessa (at) unforgettablefirellc (dot) com along with applicable measurements and your name and phone number so that we can call you in case we have any questions. Your digital photos will help us determine what venting components are required for a safe and beautiful installation in your living space and they will enable us to coach you {or your installer} through each step by phone.

Remember that the relationship between any wood stove and its flue may be compared to the relationship between the heart and lungs in the human body. In other words, if a person’s lungs do not function properly, then neither will the person’s heart function properly. In a similar manner, the function of any wood stoves is directly related to the function of its chimney, as a chimney serves as its wood stove’s lungs.

While all UL-Listed brands of pellet pipe must be manufactured to the same basic standards, we specifically recommend the use of insulated all-fuel pellet pipe, which is custom-manufactured for our gasifier wood stoves. Because our patented gasification technology causes the combustion to be more complete and results in lower flue temperatures than chimneys used with traditional wood stoves, the insulated pellet pipe will help to keep the interior flue temperature sufficiently warm for the chimney to function properly even under the most challenging of winter conditions.

Additional Requirements For Residential Installations

For residential installations, you must always follow your local and county regulations designed for your safety. This typically means a Class-A pass-through from the ceiling through the attic and roof, which can add an additional $250.00 to $500.00 to your venting costs. See our Kimberly™ and Katydid™ Owner’s Manuals for complete installation instructions and diagrams.
