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.
