Product overview

The Napoleon BLX46NTE is a 46-inch Ascent Linear Premium natural gas fireplace with electronic ignition and a single-sided, built-in contemporary firebox. Select model-specific decorative media and finishing accessories to complete the installation. The image shows a configured fireplace; decorative logs and interior finishes shown are sold separately.

Build Configuration and Venting

This exact model is natural gas with electronic ignition. Choose one compatible log set. Optional glass and enhancement media are offered alongside that verified log-set configuration; a glass-only build is not offered pending manufacturer clarification. The ProFlame II remote, eFIRE controller, blower, adjustable finishing flange and premium safety barrier are included. Use an approved 4-inch exhaust / 7-inch intake top-vent system. Venting Options provides route alternatives; select a complete installation-specific system, including appropriate terminations, lengths, supports and firestops, according to the exact manual. Venting selections are optional for ordering. GA-72 needs LHAD or GA-566; use only compatible heat-management combinations.

Installation and safety notes

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.
