Getting Started
A. Design and Installation Considerations
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.
No additional outside air source is required.
The Twilight-II-B has been carefully engineered to pro-
vide a unique fi replace experience. Since it is different
than any other product on the market, care must be taken
when installing this appliance so that our customer does
not experience undesirable performance or conditions.
1. Install the appliance according to this Owner's Guide
paying particular attention to fl ashing and sealing in-
structions.
2. In the cold northern climates pay attention to expo-
sures and prevailing wind conditions when locating the
appliance, the same as you would for locating exterior
windows and doors.
The Twilight-II-B has the thermal characteristics of a high
quality window system. Temperatures near the appliance will
be cooler than what is realized with a fully insulated wall.
Operation of the appliance will eliminate any cool drafts
and will provide the room with a comfortable ambiance.
CAUTION
Check building codes prior to installation.
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult insurance carrier, local building, fi re offi cials or
authorities having jurisdiction about restrictions, installation
inspection, and permits.
When planning an appliance installation, it's necessary to
determine the following information before installing:
• Where the appliance is to be installed. See Section 3.
• Gas supply piping. See Section 6.
• Electrical wiring. See Section 7.
• Framing and fi nishing details. See Sections 3 and 8.
• Whether optional accessories—devices such as a fan, wall
switch, or remote control—are desired. See Section 9.
WARNING
Keep appliance dry.
• Mold or rust may cause odors.
• Water may damage controls.
