VENT OPENING PREPARATION

Important:
This appliance is supplied with a vent unit requiring the
center of the vent hole to be 47
appliance if installed with a pedestal base or 46" above the
bottom of the appliance if installed with legs. This height
must not be reduced by cutting the vertical portion of the
elbow duct. For higher vent openings, one or two optional
vent extension kits #905VEK must be used - See venting
graph figure 1 for the allowable range of heights and
number of extensions required. Before cutting the vent
opening in the wall, make sure that the installed distance
to the bottom of the appliance is known. Once the vent
opening in the wall is cut it will not be possible to alter the
position of the appliance without re-cutting the wall.
