Venting selections are optional for ordering. GA-72 needs LHAD or GA-566; use only compatible heat-management combinations.

A qualified installer must follow the model-specific venting charts, framing diagrams, combustible clearances and finishing instructions in the installation manual and applicable codes. Appliance dimensions are not rough-opening dimensions. Framing and finishing must not extend inside the finishing flange. Do not mix rigid and flexible venting or vent components from different manufacturers. Maintain the approved combustion-air and exhaust paths. Install the safety barrier and correctly seal the glass door before use. Position approved logs and media exactly as instructed; blocked burner ports can produce unsafe flame patterns. Optional heat management does not eliminate its documented installation requirements.
