Section 2: Framing The Fireplace; Clearances - Montigo H34VO Installation & Maintenance Manual

H-Series VO Outdoor Gas Fireplace
Section 2: Framing
Choosing The Fireplace Location
The H-Series VO may be installed in an outdoor setting such as a
patio or balcony. Choose a location that maintains proper clearance to
combustibles as noted in the clearances chart.
Note: The H-Serie VO may not be recessed into the exterior wall.
Figure 2. Choosing the fireplace location.
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.

Installation
warning:
When covering the upper metal portion of the fireplace with a non-
combustible material Please Note: The decorative facing materials
may be subject to temperatures in excess of 250° F. This should be
considered when selecting facing materials.
Please be aware; temperatures over the mantel will rise above normal
room temperature and walls above fireplace may be hot to touch.
We recommend careful consideration be given to the effects of elevated
mantel temperatures which may be in excess of product design, for
example: candles, plastic or pictures.
When installing a shelf over the top of the fireplace, the minimum
clearance from the top of the fireplace to a shelf is 9".
When raising the hearth, the minimum clearance from the top of the
M"
fireplace to a combustible ceiling is 36".

If the Optional drain pan is not used during construction; (as shown
in Figure 2a above) ensure any water build-up can escape to the
exterior of the finished enclosure.
Water penetration can occur, and accumulate in the base of the
fireplace, and if not taken into consideration can cause deterioration
of materials, and may cause premature failure of the structure.
