1. Description
You must first verify you have the correct kit for your HHT fireplace. Refer to your installation instructions/owner’s
manual for the correct chimney air kit (CAK) to be used. The CAK4A includes a chimney air box assembly, an out
side air inlet vent hood with stucco flange, two wire ties and a hardware package. See Figure 1.
2. Installation
•
Once the chimney pipe is installed, place the box on top of the fireplace around the chimney pipe and attach the two
halves of the CAK together. See Figures 2 and 3. Installation on a see-through fireplace will require bending the tabs
down to match the angle of the top pan/smoke shield. See Figure 3.
•
Use the pre-punched holes in the tabs as guides and drill 3/32” holes through the fireplace top.
•
Secure the box with the screws provided.
