HIGH ALTITUDE DERATION
This Tubular Unit Heater has been manufactured utilizing 
standard burner orifices and a normal manifold pressure 
setting as per the specifications shown on your unit rating 
plate.

All unit deration must be done through field adjustments by 
a qualified technician. Once the proper adjustments are made 

in the field, attach label #J17-06459 to the unit, and record 
adjusted manifold pressure, altitude of the unit installation 
and the technician’s name and date on the label using a 
permanent marker.

Refer to Installation Instruction section on Adjustments-Gas 
Input Rate for adjusting the manifold pressure.
