Getting Started
A. Design and Installation Considerations
Hearth & Home Technologies direct vent gas appliances
are designed to operate with all combustion air siphoned
from outside of the building and all exhaust gases ex-
pelled to the outside. No additional outside air source is
required.
Installation MUST comply with local, regional, state and
national codes and regulations. Consult insurance carrier,
local building inspector,
fi
re of
fi
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 con
fi
guration to be used.
• Gas supply piping requirements.
• Electrical wiring requirements.
• Framing and
fi
nishing details.
• Whether optional accessories—devices such as a fan,
wall switch, or remote control—are desired.
D. Inspect Appliance and Components
• Carefully remove the appliance and components from
the packaging.
• The vent system components and decorative fronts may
be shipped in separate packages.
• If packaged separately, the log set and appliance grate
must be installed.
• Report to your dealer any parts damaged in shipment,
particularly the condition of the glass.
•
Read all of the instructions before starting the instal-
lation. Follow these instructions carefully during the
installation to ensure maximum safety and bene
