Introducing the Heat & Glo Gas Fireplaces

Heat & Glo direct vent gas fireplaces are designed to oper- ate 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.

Pre-install Preparation

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 may be 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.

The Heat & Glo Warranty will be voided by, and Heat & Glo disclaims any responsibility for, the following actions:

•Installation of any damaged fireplace or vent system component.

•Modification of the fireplace or direct vent system.

•Installation other than as instructed by Heat & Glo.

•Improper positioning of the gas logs or the glass door.

•Installation and/or use of any component part not manu- factured and approved by Heat & Glo, not withstanding any independent testing laboratory or other party approval of such component part or accessory.

ANY SUCH ACTION MAY POSSIBLY CAUSE A FIRE HAZARD.

When planning a fireplace installation, it’s necessary to determine:

•Where the unit is to be installed.

•The vent system configuration to be used.

•Gas supply piping.

•Electrical wiring.

•Framing and finishing details.

•Whether optional accessories—devices such as a fan, wall switch, or remote control—are desired.

If the fireplace is to be installed on carpeting or tile, or on any combustible material other than wood flooring, the fireplace should be installed on a metal or wood panel that extends the full width and depth of the fireplace.
