Operating Instructions and Owner’s ManualENERCO GROUP, INC. |Indirect Fired Portable Heater
APPLIANCE DESCRIPTION
Mobile space heater with:
• closed combustion chamber and gas exhaust duct (indirect-
fired models)
• open combustion chamber (direct-fired models)
INSTALLATION INSTRUCTIONS
General instructions
• The heater must be operated only by properly trained
personnel. The manufacturer’s instructions must be followed.
• The heater must be installed and operated so that people are
not exposed to dangers deriving from exhaust gases, from the hot
air flow and in such a way that no fire risks exist.
• It is forbidden to install the heater in the surroundings of
flammable materials, combustible products, or in places where
explosion risk exist.
• When the heater is used in a closed room, ensure a minimum
volume of 28,300 ft³ for the HS180ID model and 53,000 ft³ for the
HS300ID model and a continuous natural air circulation through
windows and doors. For a good combustion, provide approximately
47 cfm air flow from outside.
• For the use of the heater the general and special fire safety
regulations in force in all fields of applications must be followed. In
any case the following minimum safety clearances from materials
or objects in the surroundings of the heater must be ensured:
