Just have your installer add it into an existing masonry fireplace and reap the benefits of the low-maintenance and cost-effective heat.

Simple Operation

One of the features that makes the Chaska 25 fireplace insert so popular is the easy to operate remote. All the functions you need to control your insert are easily accessible with the touch-control remote. Quickly adjust the fan speed and the flame size to get the level of warmth you want.

Small Size with High Performance

Small and efficient, the Chaska 25 operates up to 25,500 BTU/hr for LP and 26,000 BTU/hr with natural gas. It is Canada P-4 approved and has an efficiency of about 79% for both LG and natural gas. You won’t need another source of heat to keep your cozy room warm and ready to enjoy.

Natural Look

The natural look of the logs is achieved with a hand painted and patented hand-crafted design. It gives the appearance of a fine wood fire with the exception of the mess and smoke involved with a true wood fire. The ceramic glass provides safety while the safety screen front adds safety and a traditional look.

Designed to offer great value, the Chaska 25 will provide reliable zone heating that’s efficient and will help keep your fuel bills low.
