H42DF-O Outdoor Gas Fireplace
Installing The Fireplace Shell
The fireplace may be installed in any location that maintains proper clear-
ances 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.

Clearances
These clearances apply to all dimensions except the framed opening,
where the clearance to combustibles is 0". The H42DF-O clearance to
unprotected combustible walls which are perpendicular to the fireplace
opening, must not project beyond the shaded area shown in Fig. 24.
For protection against freezing temperatures, it is recommended that
outer walls of the chase be insulated with a vapor barrier. This will reduce
the possibility of a cold-air convection current on the fireplace.
