THE CHASKA 34
Transform that cold, drafty fireplace with a clean efficient Chaska 34 gas insert from Kozy
Heat. The Chaska gas inserts are completely air tight and are the perfect solution to your
existing wood fireplace. The Chaska gas inserts offer a large viewing area with our most
realistic flame and log pattern yet. With three versions to choose from, the Chaska 34 insert
is available with a traditional log set, contemporary looking rock, or glass media models.
The standard light kit (log and rock model) and standard accent lighting on the glass bead
model will not only let you operate the fireplace without heat, but add that extra touch of
realism that will soon make you forget that you are not burning wood anymore!

Venting
Dual 3” Aluminum Flex Pipe
A gas insert will help in eliminating the heat loss and cold down
drafts that you have likely experienced from your existing fireplace
and chimney. As the first company to introduce direct-vent
technology to gas inserts, Kozy Heat inserts and fireplaces use 100%
outside air for combustion. Our inserts and dual 3” aluminum flex
venting structure create a sealed system and eliminates the potential
of bringing smoke or fumes into the home. When compared to gas
logs or “ventless” inserts, this is the safest and most efficient choice
that you can make for your family.
