Unvented Liquid Propane Fired Room Heater
 DANGER
HOT GLASS WILL CAUSE 
BURNS. 
DO NOT TOUCH GLASS 
UNTIL COOLED. 
NEVER ALLOW CHILDREN 
TO TOUCH GLASS. 
A barrier designed to reduce the risk of burns from the 
hot viewing glass is provided with this appliance and shall 
be installed for the protection of children and other at-risk 
individuals.
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.
