How long will my Isokern last?

Can my Isokern Fireplace be made to have a taller opening?

Yes, but there are limitations to doing this such as ceiling height, surrounding environment and indoor air quality.

Can an Isokern fireplace system sit on a wood floor?

The Vent-Free Series and B-Vent IBV Series units can sit on a wood floor. However, most wood-burning Isokern fireplaces cannot. The exception to this is the Standard Series and Magnum Series when the Fire-Lite application is applied. Please consult your local sales representative or dealer for proper fireplace selection and placement.

Vented gas logs can be used in the IBV, Standard, Magnum Series. These gas logs range from 50,000 BTU to 100,000 BTU maximum. The Vent-Free Series specifies the use of AGA listed “vent-free” log sets. The “vent-free” log sets are 40,000 BTU maximum.

Do Isokern fireplaces come with a glass front?

No. All Isokern fireplaces are designed as open front units. If glass doors are required by local code or desired, the fireplace must be burned with the glass doors in the fully open position.

Can I vent an Isokern directly out the back of the box?

No. Isokern vented units are specifically designed to vent vertically.

How much does an Isokern fireplace or chimney system cost?

Due to the fact that each Isokern system is unique there is no one set price for every region of the country. Prices may vary due to project scope, specifications and site.

Can stucco, brick or stone be directly applied to an Isokern fireplace or chimney system?
