Installing The Ductwork And The Registers; Fully Ducted System (T-1); Exhaust Ducted System (T-2) - Broan B110H65RT Manual De Uso Y Instalación

2.2 I D
NSTALLING THE UCTWORK AND THE REGISTERS
Never install a stale air exhaust register in a room where there is a combustion device, such as a furnace, gas water
heater, fi replace or any appliance or equipment that can generate gaseous contaminants, or pollutants. The negative
pressure this could create in the room may impair proper evacuation of the gas or pollutants, which may have severe health
consequences.
2.2.1 F D S (T-1)
ULLY UCTED YSTEM
S :
TALE AIR EXHAUST DUCTWORK
• Install registers in areas where contaminants and humidity are
produced: kitchen, bathrooms, laundry room, etc.
• Install registers on an interior wall, 6 to 12 inches away from the
ceiling OR in the ceiling.
• Install the kitchen register at least 4 feet away from the range.
• Bathroom fans and range hoods can be used to better exhaust stale
air.
• Homes with more than one level require at least one exhaust register
at the highest level.
F
RESH AIR DISTRIBUTION DUCTWORK
• Install registers in bedrooms, dining room, living room and
basement.
• Install registers in the ceiling OR high on the walls with the airfl ow
directed towards the ceiling.
• If a register must be installed in the fl oor, direct the airfl ow up the
wall.
NOTE: For this type of confi guration, the T-1 option must be selected on the LCD screen when auto-balancing the unit.
2.2.2 E D S
XHAUST UCTED YSTEM
Duct connection to the central forced-air system can be regulated by some codes and standards. It is your responsibility
to consider and comply with your local requirements to avoid any non-compliance.
S :
TALE AIR EXHAUST DUCTWORK
Same as for Fully Ducted System, described on point 2.2.1.
F :
RESH AIR DISTRIBUTION
• Connect the fresh air distribution duct of the unit to the central forced-
air system return duct at least 10 feet away from the central forced-air
system (A+B)*.
* This 10-ft. distance applies only in areas where the outside temperature
falls below the freezing point (32°F).
NOTE: The central forced-air system blower operation can be synchronized
with the unit (see Section 3.3). It is recommended, but not essential that the
central forced-air system blower runs when the unit is in operation.
NOTE: For this type of confi guration, the T-2 option must be selected
on the LCD screen when auto-balancing the unit.
(T-3)
A :
LTERNATE INSTALLATION
Unit should be synchronized with central forced-air system operation
to avoid condensation and mold growth in central forced-air system
distribution ducting if cooling mode of central forced-air system is used.
This confi guration is not recommended with high velocity central
forced-air system. High pressures produced by these systems
could affect unit proper operation and generate errors.
NOTE: For this type of confi guration, the T-3 option must be selected
on the LCD screen when auto-balancing the unit.
