If a Model UDAS or UDAP heater is being installed above 2000 ft (610M), the input rate must be derated. This is done by adjusting the valve outlet pressure as explained in the heater installation manual. In addition, if the heater is being installed at an altitude above 6000 ft (1830 M), the pressure switch must be changed. The high altitude pressure switch ordered as Option DJ20, High Altitude Kit, varies by Model, Size, and type of application. Be sure your kit matches your installation. 0RGHO8'$3LQVWDOOHGDVVWDQGDUG3RZHU9HQWHG8QLW+HDWHU 6L]H 3NJ31 High Altitude Switch P/N Negative Pressure OFF Setpoint "w.c. Label color
