CAUTION:  Never  connect  heater  directly  to  the 

Propane supply. This heater requires an external 

regulator (not supplied). Install the external regula-

tor between the heater and Propane/LP supply. 
The installer must supply an external regulator. 

The external regulator will reduce the incoming 

gas pressure to between 11 and 14 inches of 

water. If you do not reduce incoming gas pres-

sure heater regulator damage could occur. Install 

external regulator with the vent pointing down. 

Pointing the vent down protects it from freezing 

rain or sleet.
