Installation; Installing The Fireplace Shell - Montigo H38DF Installation Operation & Maintenance

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:

Clearances
These clearances apply to all dimensions except the framed opening,
where the clearance to combustibles is 0". The H38DF clearances to
combustible materials are:
Top - Rear Vent*
Top - Top Vent
Back
Sides
Floor
Mantle**
* Clearance from the top of the fireplace to a combustible
ceiling within the fireplace enclosure.
** Refer to page 11.
Unprotected combustible walls which are perpendicular to the fireplace
opening, must not project beyond the shaded area shown in Figure 23.
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.
