HORIZONTAL VENT HEAT SHIELD INSTALLATION

The horizontal vent heat shield must be installed when using a 45-degree elbow to horizontally position the vent system.
IMPORTANT
EXCEPTION: Corner installations
1.
Loosen, but do not remove center three screws at back of fireplace as shown.
2. Bend horizontal vent heat shield at perforation to a 45° angle. Slide (3) slots on
horizontal vent heat shield under loosened screws. Re-tighten screws.

WALL ENCLOSURE ROUGH OPENING

Framing dimensions should allow for wall covering thickness and fireplace facing materials. If using a hearth, ad just rough
opening size as necessary to maintain at least minimum clearance requirements.
IMPORTANT
Non-combustible facing material may be applied over (but not directly to) fireplace face. This will prevent facing material from
falling off due to heat expansion. Do not obstruct the flow of ventilation air.
