    FAQ

    Is the Chaska 335S available for propane? Yes. Choose Propane (LP) above. Some models come factory-converted; others ship with the LP orifices and need the valve step motor, which is included in the LP price.

    Does the price include the front and venting? No. Chaska 34 Screen Front, Chaska 34 Insert Shroud must be added (choose them above Add to Cart). Venting and termination parts depend on your home, so we quote them after a quick conversation.

    Can you help me size and plan the install? Yes. Call or visit one of our North Carolina showrooms and we'll go over sizing, venting runs and finishes with you.

    Where is it made? Kozy Heat Fireplaces builds its fireplaces in Lakefield, Minnesota.
