Installing a Wall Mounted RHS8 Heat shield
The RHS8 Heat shield CANNOT be used when the Termination is WITHIN
(36" Min. horizontal and 46" Min. vertical) from the fireplace, or directly
off the rear of the fireplace, as shown figure 16a. The RHS101 Heat
Shield (Figure 17 and 17a) MUST be used within the noted dimensions.
To install the RHS8, frame an opening in combustible construction,
Figure 16 below. Slide the Heat shield in place over the vent pipe
which attaches to the fireplace. After the fireplace and vent pipe has
been installed, clearances should match the dimensions in Figure 16.
