Unvented LP-Gas Vent Free Room Heaters
•
Surface of heater becomes very hot when
running. Keep children and adults away
from hot surfaces to avoid burns or clothing
ignition. Heater will remain hot for a time after
shutdown. Allow heater surfaces to cool before
handling.
• Young children should be carefully supervised
when they are in the same room with heater.
• Make sure grille guard is in place before
running heater. If screen or grille guard is
removed for servicing it must be replaced prior
to operating the heater.
• Keep the appliance area clear and free from
combustible materials, gasoline, and other
flammable vapors and liquids.
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
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.
