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.
