RSF Woodburning Fireplaces
When the Keystone Louver is installed, no gravity vents are required. Hot air circulation will flow out of the
Keystone Louver. Gravity vents remain optional, but are not mandatory in this configuration.
Gravity vent Options
Gravity vent kits allow hot air to be ducted from the fireplace to a room above or on the same level as the fireplace.
OPEL+ KEYSTONE installations without the Keystone Top Louver require two gravity vents for heat circulation.
Each gravity vent kit includes 5’ of insulated flexible ducting, a fireplace adapter, an outlet grill adapter, and a
decorative outlet grill.
Additional 5’ lenghts of insulated flexible ducting can be ordered with the part code FO-DUCT5. Nevertheless,
gravity vents have a maximum length of 15’.

Heating Options
For increased air circulation and marginally more heat output, you can add the Circulating Internal Blower (FO-
FDHB5-N) to your Louvered OPEL+ KEYSTONE.
For constant heat, day and night, you will be surprised by what the Thermostat Option (FO-FDHC4) can do for you.
This option provides you with the necessary parts to automatically control the draft control via a wall thermostat. It
will keep your room temperature as even as though you were heating with oil, gas or electricity, except you will find
wood heat more comfortable.
To maximize the distribution of the heat generated by your OPEL+ KEYSTONE fireplace throughout many rooms
and different floors, consider the Central Heat Option. With our Central Heat Blower (FO-FDHB6-1), you can use
ducts to circulate the fireplace heat to one or many rooms. The Central Heat Control (FO-FDHC6) will enable
automatic control of the Central Heat Blower via a wall thermostat and thermal switch. The Zone Heat Control (FO-
FDHCZ1) along with Zone Damper Kits (FO-FDHCZ2) will provide the same features as the Central Heat Control
but for more than one heating zone. If you wish to install the Central Heat Blower on a Clean Face OPEL+
KEYSTONE, you will need the Central Heat T (FO-T) that will enable you to connect the central heat duct along
with the left gravity vent on the fireplace.
For a simpler way to circulate a moderate amount of warm air from the fireplace to another room, we offer the Heat
Dump Kit (FO-HD) which uses a smaller fan than the Central Heat Blower. It is most often used to provide
supplemental heating to a basement room when the fireplace is on the main floor but it can also be used to send
the warm air upstairs.
General Options
To simplify the installation of thin non-combustible materials such as ceramic tile or sliced brick, we have designed
a very versatile rock retainer kit (FO-KK). It is not designed or required for full brick or stone. Thin materials can
also be installed directly on the face of the OPEL+ KEYSTONE using high temperature silicone as glue, without a
rock retainer kit.
To remove accumulated ashes from the firebox, simply shovel them in to a metal container. Nevertheless, you may
find the optional Ash Pan Kit (FO-AP) very convenient. You remove the plug from the firebox and sweep the ashes
into a hole to the ash pan. When the ash pan is full, simply remove the ash pan by the bottom louver and dispose
of the ashes properly.
NOTE
: Many options require wiring and/or electricity for their installation. If there is any chance that any of these
options will be installed in the future then suitable wiring should be run during framing. Otherwise, it will be difficult
to install these options later. You can refer to page 31 for a list of options that require electricity.
