Getting Started

A. Design and Installation Considerations
WARNING! Risk of Fire or Explosion! Read all instruc-
tions before starting the installation.
Heat & Glo direct vent gas appliances are designed to
operate with all combustion air siphoned from outside of
the building and all exhaust gases expelled to the outside.

Installation MUST comply with local, regional, state and
national codes and regulations. Consult insurance carrier,
local building inspector, fi re offi cials or authorities having
jurisdiction over restrictions, installation inspection and
permits.
Before installing, determine the following:
• Where the appliance is to be installed.
• The vent system confi guration to be used. If Passive
Heat will be installed, consider location of discharge
opening in relation to venting and other construction
materials.
• Gas supply piping requirements.
• Provisions for optional heat management system.
• Electrical wiring requirements.
• Framing and fi nishing details.
• Whether optional accessories—devices such as a fan,
wall switch, or remote control—are desired.
