Framing Dimensions
The dimensions given on this page are minimum framing distances neces-
sary to maintain safe clearances between the Ravelle™ 42 gas fireplace
and combustible materials.
uIf 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
10-3/4” (273 mm) square with a center line 42-1/4” (1073 mm)
above the base of the fireplace will accommodate the wall thimble
and direct vent pipe.
vThe gas line should be routed to the left side of the unit. The access
hole in the fireplace for the gas line is 6-7/8” (175 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.
wThe 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).

Figure 3
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 than 1” (25 mm) thick is going to be used, the fire-
place 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 on this page are minimum and
show the stand-offs on the rear corners of the fireplace up against the
corner walls.
