general recOMMendatiOns
This indirect-fired heater runs on natural gas or L.P.G. and is
fitted with a flue to take the fumes away through the chimney.
Prior to shipping, the heater is configured for either natural gas
or lP, labeled on the gas selector valve for the correct fuel type
and given a complete functional test. To change the type of gas,
follow the detailed instructions indicated in section “CHANGING
TYPe oF GAS”.
Always follow local ordinances and codes when using this
heater:
• Read and follow this owner’s manual before using the
heater.
• Use only in places free of flammable vapors or high dust
content.
• Never use heater in immediate proximity of flammable
materials (the minimum distance must be 6 ft.).
• Make sure fire fighting equipment is readily available.
• Make sure sufficient fresh outside air is provided according
to the heater requirements. Direct combustion heaters
should only be used in well vented areas in order to avoid
carbon monoxide poisoning.
• The heater is installed near a chimney to take away the
fumes (see “Ventilation” on page 5) and connected to an
electrical switchboard.
• When the heater is connected to a flue pipe, the flue pipe
shall terminate in a vertical section at least 3 feet long and
sufficient draft shall be created to assure safe and proper
operation of the heater.
• Never block air inlet (rear) or air outlet (front).
• In case of very low temperatures add kerosene to the
heating oil.
• Make sure heater is always under surveillance and keep
children and animals away from it;
• Before starting the heater always check free rotation of
ventilator fan.
• Indirect fired units only can be connected to air ducts to
distribute warm air, with respect to the max. static pressure
declared (see “TeCHNICAl SPeCIFICATIoN” sheet).
• Unplug heater when not in use.
