M38ODV-ST Direct 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 & Combustion Air Kit installation.
The fireplace dimensions are shown below:

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.
Frame the fireplace cavity according to Figure 2a.
Slide the fireplace into the cavity.
Tack four studs (40" length) in place as shown in Figure 2b. Secure
the fireplace in position by nailing into these cleats.
Framing Above the Fireplace
When installing a shelf or any other combustible construction over the
top of the fireplace, you must use an Offset Box (Part No DVST-CNT).
The Offset Box provides a top clearance of 16" to combustible
materials. The minumum shelf height is 49", when measuring from the
hearth to the underside of the shelf. See Figures 9 and 10.

(Minimum 1" clearance must still be maintained around the vent pipes,
except on horizontal venting sections where the top of the pipe must
