This	chart is intended as a guide only, as heaters may be mounted at various heights and angles. Since straight tube heaters ar	e always hotter at the burner end than
at the exhaust end, always observe the minimum recommended mounting heights shown above. Use ETU series for spot heating. Pleas		e consult your local Space-
Ray	Representative for a detailed analysis of your particular infrared heating requirements.

*When used indirect vented, clearances to ceiling from top of exhaust hood must be 12” on ETS/U (40-75), and 18” on ETS/U (80-250). If optional corner or U-bend reflectors are not used, clearance must be 18”. **Clearance below the heater is 132” for the first 20 ft. of the emitter tube and reduces to 72” 20 ft. downstream from the control box.

Note: Consult factory if reduced clearances are required.
