per foot (63 mm/ 300 mm) toward the vent terminal - radiant tube must be level.

continued ……..

heaters must be controlled by a single common thermostat or “ON/OFF” switch.

Install a minimum 36 inch (91 cm) length of minimum 26 gauge single walled 4” (10 cm) di-
ameter vent pipe on the system, and a minimum 12 inch (30 cm) before any Tee or Elbow.

Any horizontal vent pipe must slope approx. 1/4” per foot away from heater



When the vent pipe passes through a cold or unheated area where the ambient temperature
is likely to produce condensation of the flue gases, the vent pipe will be insulated with a suit-
able material as approved and specified by the insulation manufacturer to withstand tem-
perature up to 460°F (238°C).



The vent system must always be adequately supported to prevent sagging.
