HOT AIR DUCTING INSTALLATION
(OPTIONAL)
Different hot air ducting systems can be installed
with the Cambria™ fireplace:
• Gravity kit
• Forced air kit
The gravity kit is used when the rooms are on
same level or floor as the fireplace or on an upper
level or floor. If the heat to be distributed is on
a lower level or floor or through the central
heat duct of a furnace, then the forced air kit
MUST be used.
Gravity Kit
Double hot air outlet including:
(See Figure 21)
• 2 ea. telescopic lengths, 8” I.D.
• 2 ea. 90º elbows, 8” I.D.
• 2 ea. hot air outlet kits (grill and frames)
• 2 ea. adaptors
See components list on Page 23.
Only the blower available with the fireplace can
be used with the gravity kit.
Grill
Frame
When installing the double outlet system, the hot air outlets can be installed in the same room as
the fireplace, or one or both of the outlets can be installed in adjacent or upper rooms. Installing the
ducts at different elevations will tend to exhaust more heat out of the higher outlet (Figure 22).
The safety rules for hot air ducting gravity kit
installations are the following:
Minimum height* 68” (1727 mm)
Maximum length - See Figure 22
* The height of t
he louver must be measured
from the base of the Cambria fireplace to
the middle point of the louver.
WARNING: Both pipe of the double hot air
outlet must be installed. Any other installa-
tion can cause greater risk of fire and void
the warranty.
