HOT AIR DUCTING INSTALLATION

Different hot air ducting systems can be installed 

with the WRT4820WS fireplace:

- Gravity kit

- Forced air kit

Gravity Kit

The gravity kit is designed for double hot air 

outlets and includes: (See

 Figures 20 and 21)

  - 2 telescopic lengths  8” I.D.

  - 2  90º elbows  8” I.D.

  - 2 hot air outlet kits (grill and frames) 

  - 2 adaptors

See 

Gravity Kit Accessories

 on 

Page 24

.

The only blower that can be used with the gravity 

kit is the UZY6.
The gravity kit must be used with the clean face 

kit to allow hot air flow that would normally 

come out of the top louver. To do so, follow 

the steps below:

a)  Install the clean face kit making sure that 

the insulation strip is installed inside.

b) The fireplace façade can be covered with 

non-combustible material 

(Figure 22)

.

For safe installation, the gravity kit must meet 

the following requirements:

Minimum height*  68”  (1,727 mm)

Maximum length 

See

 

Figures 20 and 21

*  The height of the louver must be measured 

from the base of the WRT4820WS fireplace to 

the middle point of the louver.
To extend the double outlet system forward 

of the WRT4820WS fireplace (not flush), it 

will be necessary to purchase two adjustable 

lengths (H8951).  
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 21)
