ONE FIREPLACE, TWO LOOKS.

As part of the growing Opel family, the Keystone is the result of fine craftsmanship, inspired by versatility and built on more than 30 years’ of proven performance with high efficiency wood–burning fireplaces.

The Keystone name comes from the interchangeable keystone facing that is offered either as a semi-clean look or as a full faceplate, adding modern sophistication and design choices to any mid-sized space.

THE RSF COMFORT ADVANTAGE

Comfort is our specialty. We customize heat distribution from a wood fireplace throughout the home, including the basement. When the household temperature is tailored for a family at minimal cost and maximum efficiency, we call that the RSF Comfort Advantage.

Note: the central heating option is not available for the Pearl 3600, the Focus 3600 or Focus ST.

Available Options

This adapter will attach to the liner with 3 stainless steel rivets (provided) and to the EXCEL chimney with 3 screws (provided).
