HOT AIR DUCTING INSTALLATION
The WCT6820WS wood burning fireplace is
approved for use with a Gravity kit (hot air
ducting system).
Gravity Kit
The gravity kit is designed for double hot air
outlets and includes: (See
Figure 14).
- Two (2) telescopic lengths 8” I.D.
- Two (2) 90º elbows 8” I.D.
- Two (2) hot air outlet kits
(grill and frames)
- Two (2) adaptors
See
Gravity Kit Accessories Page 21
.
For safe installation, the gravity kit must meet
the following requirements:
Minimum height*
68” (1,727 mm)
Maximum length
See
Figure 14
* The height of the louver must be measured
from the base of the WCT6820WS fireplace to
the middle point of the louver.
The only blower that can be used with the gravity
kit is the one sold with the fireplace.
To extend the double outlet system, it will be
necessary to purchase two adjustable lengths
(H8951).
Figure 15
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 (

FIREPLACE BLOWER
The fireplace comes equipped with a heat acti-
vated blower. It is located in the bottom of the
fireplace, towards the back. It uses 120V and
must be connected to the main electrical circuit
by a qualified electrician. For connection, use the
electrical box supplied with the unit located on
the bottom right corner of the fireplace.
If you wish to adjust the blower speed, the
variable speed control (VRUW) provided must
be installed in line with the wiring. Again, use
a qualified electrician for installation.
If the blower requires servicing,
1- Remove the doors and decorative facade.
2- Remove the screw located below the blower
motor that holds it to the back of fireplace.
3- Pull the blower out of the unit through the
square hole located in the front bottom right
corner.
