INSTALLATION

Framing Dimensions
The dimensions given below are minimum framing distances necessary
to maintain safe clearances between the Ravelle™ 30 gas fireplace and
combustible materials.
u
If the unit is to be vented horizontally with a 90º elbow right off the
top of the fireplace and directly through an exterior wall, then a hole
9-1/4" x 10-3/4" (235 mm x 273 mm) square with a center line 34"
(864 mm) above the base of the fireplace will accommodate the wall
thimble and direct vent pipe.
v
T he gas line should be routed to the left side of the unit. The access
hole in the fireplace for the gas line is 6-1/4" (159 mm) back from
the front edge and 2-1/8" (54 mm) up from the base of the unit. If
the gas line enters the unit from the right side, the piping will need to
be disconnected to remove the fan.
If a wall-mounted on/off switch or thermostat is to be used, these
wires should be routed to the left front of the unit for access to the
fireplace. The wire should be fed through the gas line hole, along the
gas line, to the valve.
w
The electrical power supply wiring should be routed to the right rear
of the unit.
Note: The fireplace may be placed directly on wood or non-combustible
flooring, but not on vinyl floor covering or carpet.
Framing Suggestions:
The framing header above the front of the
fireplace should be as narrow front to back as allowable to give maximum
clearance to the direct vent pipe (i.e. don't use a 6" (152 mm) thick header
when a 4" (102 mm) thick one is allowed). A 6" (152 mm) header may
need to be notched to accommodate vertical vent pipe. If the fireplace is
going to be horizontally vented directly out the back, do not place a stud
in line with the wall thimble. If a hearth extension greater then 1" (25mm)
thick is going to be used, the fireplace and the header must be raised
accordingly. See Hearth Extension Considerations for further details.
Insulation:
The exterior walls adjacent to the fireplace should be
insulated like the rest of the house, but insulation should not be placed
around the fireplace or vent pipe.
Corner Installations:
The dimensions below are minimum and show
the stand-offs on the rear corners of the fireplace up against the corner
walls.
