MD44-DV Direct Vent Vented Fireplace
Installing The Fireplace Shell
The fireplace may be installed in any location that maintains proper
clearances to air conditioning ducts, electrical wiring and plumbing.
Safety, as well as efficiency of operation, must be considered when
selecting the fireplace location. Try to select a location that does not
interfere with room traffic, has adequate ventilation, and offers an
accessible pathway for Direct Vent installation. Refer to page 4 -
Vent
Installation for more information.
The fireplace dimensions are shown below:

** See Vent Termination Section
for framing of termination opening.
When installing a shelf over the top of the fireplace, the following
guidelines must be adhered to: For Rear Vent models (MD44DR),
the minimum clearance from the top of the fireplace to a shelf is 10".
For Top Vent models (MD44DT), the normal minimum clearance is
44".
However, if the horizontal vent run is 12" or less, then the top
clearance is reduced to 15 1/2". ( Minimum 1" clearance must still be
maintained around the vent pipes.)
See Figure 4.

Figure 4. Framing for shelves over the fireplace.
Unprotected combustible walls which are perpendicular to the
fireplace opening, must not project beyond the shaded area shown in
Figure 19b.
For protection against freezing temperatures, it is recommended that
outer walls of the chase be insulated with a vapour barrier. This will
reduce the possibility of a cold-air convection current on the fireplace.
WARNING:
When this appliance is installed directly on carpeting, tile or any
combustible material other than wood flooring, it must be installed
on a metal or wood panel extending the full width and depth of
the appliance.
