OPEL PLUS C Owner's Manual 18 RSF Woodburning Fireplaces
CEILING CLEARANCE
Ceiling clearance is the distance from the base of the fireplace to the ceiling. If you vent the fireplace enclosure,
you can then have a lower ceiling clearance as specified in Table 1 (C) for a vented enclosure.
For a vented enclosure, you MUST install regular venting 3"x10" grilles or larger into holes cut within 1' of both the
floor and the ceiling, to allow room air to circulate through the fireplace enclosure and reduce heat buildup. These
venting grilles may be placed vertically or horizontally.
Under no circumstances should the distance between the ceiling firestop and the base fireplace be less than the
dimension specified in Table 1 (C).
SECURING THE FIREPLACE IN PLACE
The fireplace MUST be attached to the floor.
Using the four small brackets that were securing the fireplace to the crate, attach the casing or base of the fireplace
to the floor. Position the brackets all around the fireplace in the same fashion as they were on the crate. If possible,
try to have at least one of the brackets screwed into the floor joist with 2" wood screws.
FRAMING
The enclosure walls can be framed with any suitable materials (2x4 or 2x6 studs, plywood, gypsum board, etc.).
Because of the high heat output potential of the OPEL, combustible materials must NOT go closer to the fireplace
than the standoffs, top, back and sides.
❖
WARNING: COMBUSTIBLE FRAMING IS NOT PERMITTED IN THE SPACE DIRECTLY ABOVE THE
FIREPLACE. THE ONLY EXCEPTION IS FOR FRAMING USED TO SUPPORT THE FACING MATERIAL AND
MANTEL. THE AREA ABOVE THE FIREPLACE MUST BE FREE OF COMBUSTIBLES FOR AT LEAST THE
HEIGHT PROVIDED IN TABLE 1 (C).
OUTSIDE AIR DUCT
After the fireplace is correctly positioned, connect the
outside air inlet to the outside (see Figure 10).
Use an insulated aluminium flexible duct rated at over
200° F. The duct should not exceed 12' vertical rise
above the base of the unit.
The air inlet should always be at least 5’ lower than
the chimney rain cap and must never terminate in
attic spaces.
A 4" diameter duct can be used if the total duct run is
less than 25'. For longer runs, use 5" diameter duct.
Both 4" and 5" connecting sleeves are provided with
the fireplace.
1. Find a convenient location for the combustion air
duct and outside air inlet. The outside air inlet can
be above or below floor level.
2. Make a 4 ¼" (5 ¼" if using a 5" diameter duct) hole
in the outside wall of the house. Push the outside
air inlet in from the outside. Seal the joint between the air inlet and the outside wall with an appropriate sealant.
3. Place the insulated flexible duct over the round sleeve on the outside air inlet. At both ends, carefully pull back
the insulation and plastic cover, exposing the flexible duct. Then at each end, attach the duct with metal screws
to the air inlet and to the fireplace connecting sleeve. Carefully push the insulation and cover back over the
duct. Tape the plastic cover in place with 2" aluminium duct tape.
You can make a cold air trap by looping the outside air duct as shown in Figure 8 and Figure 9.
