RSF Opel Plus Keystone Wood Fireplace

Opel Plus Keystone

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.

Low Emissions – High Performance

  • Semi-clean face option (requires two gravity vents for heat output)
  • Full Keystone facing for maximum impact
  • EPA Certified to comply with 2020 particulate emission standards at 0.7 g/hr. (with the 635cfm Central Heating Blower option)
  • Large 3.6 cubic feet firebox allowing overnight burns.
  • BTU Output range 10,000 to 70,000
  • Heating capacity up to 3000 ft2



Opel+ Keystone Louver (Top) The Top Louver for the Opel+ Keystone is a required option when the top louver is not blocked on the fireplace.
Gravity Vent Kit The gravity vent kit uses natural convection to distribute the heat generated by the fireplace to the same floor and/or floors above the fireplace.
Gravity Vent Kit – Rectangular The gravity vent kit uses natural convection to distribute the heat generated by the fireplace to the same floor and/or floors above the fireplace.
Internal Blower The internal blower kit will increase the circulation of heated air in the room where the fireplace is installed.
Central Heat Blower Kit The central heat blower kit enables the distribution of heat generated by the fireplace throughout many rooms and different floors using either dedicated ducts or the house central heating ducts.
Central Heating Tee This Tee allows you to have two Gravity Vents (FO-V2) on your fireplace and still be able to install the Central Heat option (FO-FDHB6-1).
