IMPORTANT: READ AND UNDERSTAND THIS OPERATIONAL MANUAL

PRIOR TO ASSEMBLING, STARTING UP OR CONDUCTING MAINTENANCE

ON THIS HEATER. USING THE HEATER INCORRECTLY CAN CAUSE

SERIOUS OR FATAL INJURIES. KEEP THIS MANUAL FOR FURTHER

REFERENCE.

1. DESCRIPTION

(Pic. 1) This heater is equipped with a

dedicated burner, a combustion chamber

with ue gas evacuation to the outside

and a high performance hot air handling

fan. The air is heated by thermal energy

produced by combustion transmitted by

means of thermal exchange with the metal

surfaces of the combustion chamber and

ue gas pass.

The path of the ventilated air and ue

gas is separated by metal surfaces

joined by welds and sealing gaskets. The

combustion products are conveyed to an

exhaust duct. This must be connected to a

chimney or ue large enough to evacuate

the ue gas. Combustion air, namely the air

required for combustion, is drawn directly

from the burner, which draws it from the

surrounding environment. Its size and work

conditions must guarantee an appropriate

air exchange.

2. SAFETY INFORMATION

WARNINGS

IMPORTANT: This appliance is not

suitable for use by persons (including

children) with reduced physical,

sensory or mental capacities or who

4. OPERATING PRINCIPLES

A. Combustion chamber, B. Combustion

head, C. Fan, D. Burner, E. Control

equipment, F. Chimney.

(Pic. 2) The burner pump aspires the fuel

from the tank and sends it to the pressurised

nozzle where it is nebulised and mixed

with comburent air in the combustion

chamber. A spark triggers combustion

while the waste fumes are expelled from

the chimney. A series of sensors constantly

checks the correct operation of the heater,

stopping the cycle in the case of a fault.

The fan, located at the rear of the heater,

cools the combustion chamber and the

ue gas pass, transferring the heat from

the latter into the environment.
