and the reduction of heat loss.
Chimney Height
The total height of your completed fireplace
system from the surface the fireplace rests on
to the chimney top must not exceed 60' and
must also meet minimum height requirements.
• paneling Refer to the minimum system height chart.

Vertical Installation

Chase Enclosure
A chase is a vertical box-like structure con-
structed to surround the fireplace and chimney.
Refer to Figure 11 for a typical chase configu-
ration. As with all chimney installations, avoid
overhead obstructions such as trees, power
lines, etc. A chase should be constructed and
insulated just like any outside wall. In a cold
climate, we recommend the base of the chase
should also be insulated between the solid
continuous floor beneath the fireplace and the
chase bottom. Chase insulation in a cold cli-
mate installation is not required for safety.
