Description/
Application
The dual vent option kit permits power venting of two of the INFRA-REZ heater
models of tubular radiant heaters through only one opening in the roof or side wall of
a building. The concentric design of the vent allows each of the two heaters to be
safely operated totally independent of the other. The two heaters may be controlled
by the same or different thermostats. Heaters vented through the optional dual vent
do not have to match in capacity, length, configuration or model. The adapter box in
the dual vent kit converts the two separate vent pipe runs into the concentric vent
terminal arrangement. The dual vent adapter box is an aluminized sheetmetal box
that attaches indoors, close to the wall or roof opening.
