Installation Instructions and Owner’s Manual

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.

Improper installation, adjustment, alteration, service or maintenance can cause injury or 
property damage. Refer to this manual for correct installation and operational procedures. For 
assistance or additional information consult a qualified installer, service agency, or gas supplier. 

Read and follow instructions and precautions in User’s Information Manual provided with this 

heater.
