Pre-installation Preparation

Heat & Glo direct vent gas fireplaces are designed to operate with all combustion air siphoned from outside of the building and all exhaust gases expelled to the outside.

The information contained in this Installers Guide, unless noted otherwise, applies to all models and gas control systems.

Gas fireplace diagrams, including the dimensions, are shown in this section.

This gas fireplace and its components are tested and safe when installed in accordance with this Installers Guide. Report to your dealer any parts damaged in shipment, particularly the condition of the glass. Do not install any unit with damaged, incomplete, or substitute parts.

The vent system components and trim doors are shipped in separate packages. The gas logs are packaged separately and must be field installed.

Read all of the instructions before starting the installation. Follow these instructions carefully during the installation to ensure maximum safety and benefit. Failure to follow these instructions will void the owner’s warranty and may present a fire hazard.

This model MUST use SL-Series Direct Vent Components and Termination Kits (as indicated in this guide) for exhausting flue gases AND model AK-CFX Air Kit for combustion air. NOTE: 4-inch insulated ducting is required. See venting section for details.
