RESTRICTOR INSTALLATION:
The ENVIRO CARA has been designed for use with an add-in restrictor. The restrictor is designed to
maintain ame appearance when installing this unit with vertical chimneys as well as installations with
longer horizontal vent applications. It does this by controlling the amount of air moving through the vent
pipe.
1. Choose the appropriate restrictor for the installation (see INITIAL INSTALLATION - VENT CONFIGURATIONS AND
RESTRICTOR SETTINGS). To avoid injury, install the restrictor when the fireplace is cool or use welder’s
gloves or oven mitts.
2. Remove the glass door (see MAINTENANCE AND SERVICE - GLASS DOOR REMOVAL) and the rebox bafe (seE
MAINTENANCE AND SERVICE - FIREBOX BAFFLE REMOVAL).
3. Remove two (2) ” hex head screws for the restrictor, place restrictor in the ue collar (see Figure
30) and fasten in place with the two (2) ” hex head screws.
4. Re-install the rebox bafe and the door.
5. Wait for the unit to warm up to operating temperature to ensure a proper and clean burning unit.

1. Set the appliance in the desired location. Check to determine
if wall studs or roof rafters are in the way when the venting
system is attached. If this is the case, you may want to adjust
the location of the appliance.

connections. Assemble the desired combination of black pipe
and elbows to the appliance adapter with pipe seams oriented
towards the wall or oor, as much out of view as possible.

pipe (non-ared end). Place a bead of high temperature
silicone on the male edge of the outer pipe. Push the pipe
sections completely together, then twist-lock one section
clockwise approximately turn, until the two sections are
