CAUTION: Never connect heater directly

to the Propane supply. This heater requires

an external regulator (not supplied). Install

the external regulator 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 pressure heater regulator

damage could occur. Install external regulator

with the vent pointing down. Pointing the

vent down protects it from freezing rain or

sleet.
