A radiant tube heater will expand and contract as it heats and cools. Configuration of the vent must
allow for heater expansion.
: Orientation of the vent at 90° to heater will allow for heater expansion and
contraction.
: (See FIG. 6)
◼ Wall Thimble or flashing at wall
that allows movement of the vent
through the opening. Do not seal
the vent to the thimble or flashing
with caulking
OR
◼ Offset vent with two x 90° elbows.
Install minimum 12 inch [305 mm]
length of straight vent between
elbows. Vent can be sealed with
caulking at non-combustible wall.
◼ Other means of slip fit installation
of the vent are acceptable provid-
ing there is adequate allowance
for free expansion and contraction
of the system, and free flow of
vent gases.

For vertical vent only, two heaters can be commonly vented using 4”x 6”x 4” Vent Tee JA- 0514-XX.
Both heaters must be operated using one common thermostat. Common vent is 6 inch [150 mm] di-
ameter.
Category III (horizontal vent) heaters cannot be common vented.
