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 provide 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 exposures 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. T emperatures 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.
B. Tools and Supplies Needed
Before beginning the installation be sure that the following
tools and building supplies are available.
Reciprocating saw Framing material
Pliers Hi temp caulking material
Hammer Gloves
Phillips screwdriver Framing square
Flat blade screwdriver Electric drill and bits (1/4 in.)
Plumb line Safety glasses
Manometer Voltmeter
Tape measure Level
Non-corrosive leak check solution
1/2 - 3/4 inch length, #6 or #8 Self-drilling screws
One 1/4 inch female connection (for optional fan)
C. Inspect Appliance and Components
WARNING
Inspect appliance and components for damage.
Damaged parts may impair safe operation.
• Do NOT install damaged components.
• Do NOT install incomplete components.
• Do NOT install substitute components.
Report damaged parts to dealer.
