Installing a Wall Mounted RHS8 Heat shield
The RHS8 Heat shield CANNOT be used when the Termination is WITHIN

off the rear of the fireplace, as shown figure 17a. The RHS101 Heat
Shield (Figure 18c and 18d) MUST be used within the noted dimensions.
To install the RHS8, frame an opening in combustible construction,
Figure 17 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 17a.
