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, fire officials 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 configuration to be used.
• Gas supply piping.
• Electrical wiring requirements.
• Framing and finishing details.
• Whether optional accessories—devices such as a wall
switch or remote control—are desired.
Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. For
assistance or additional information, consult a qualified
service technician, service agency or your dealer.
