3.3.8 Outdoor Heater Install with Venting for
Extreme Weather Conditions
In the event that the heater is installed outdoors
and there are concerns over extreme weather
conditions, the heater exhaust can be converted
using Category III vent material as shown in this
section. An approved Category III vent termination
cap needs to be installed vertically. We recommend
using a vent termination cap from Z-flex (part #:
2SVSRCF04). The vent adaptor is also required and
can be ordered as R-Kit R0731100.
