DUCTING SYSTEM
Begin the duct system installation by identifying the path the
duct will take from the fireplace to the inline blower, as well as the
path from the blower to the outlets.
Determine how the duct system will be terminated, (ceiling,
floor or walls) keeping within the minimum outlet restriction
requirements.
NOTICE: This duct system cannot be vented outdoors unless
specified and installed by a HVAC engineer.
NOTICE: This duct system uses both 8" rigid aluminum ducting
and 8" wire reinforced ducting before the inline fan. After the
fan, the duct system uses either 10" wire reinforced ducting or 6"
wire reinforced ducting depending on the installation
NOTICE: All connection joints must be sealed with hose clamps
and maintain a 1 inch minimum overlap.
•
Duct fan blower has to be fully accessible after install for
servicing and maintenance.
•
Failure to follow the ducting installation instructions will
result in the improper operation of the fireplace.
•
All ducting must be rated above 140°F (60°C)
•
All ducting should be fully extended and cut to length
prior to installation.
•
Neglecting to allow back-flow of return air to the fireplace
can result in a risk to personal safety to infants or infirm
persons.
•
Overheated rooms are NOT SAFE for infants.
•
A Clearance of 1 inch must be maintained around any
duct vent.
DUCT VENT INSTALLATION
WARNING
NOTICE:
This duct vent system can be routed in any path as long as it
meets the following requirements:
•
Maximum vertical distance above Fireplace floor = 12ft
•
Maximum 1 ft below the base of the fireplace
•
If duct pipe runs downward it cannot turn back upward.
Pre Inline Blower
•
Maximum effective length to blower = 30ft (effective
length calculations shown in Equation 1).
•
Minimum effective length to blower = 6 ft *
•
Maximum length of wire reinforced duct = 1ft
•
Minimum length of wire reinforced duct = 0.5ft
•
Maximum 2-90° bends or 4-45° bends before inline
blower
Post Inline Blower
•
Maximum effective length of 10" ducting = 20ft (per
length)
•
Minimum effective length of 10" ducting = 4ft * (per
length)
•
Maximum effective length of 6" ducting = 20ft (per
length)
•
Minimum effective length of 6" ducting = 4ft (per
length)
•
Maximum 3-90° bends or 9-45° bends on 10" and 6"
ducting (per length)
•
Maximum effective combined length = 60ft (effective
length calculations shown Equation 2).
* excess fan noise may be present at this distance
