INTRODUCTION
2.1
Purpose
The heaters are indirectly fired heaters with
photocell control and connections for a room
thermostat and flue with raincover.
The heaters are tested at sea level and at a
temperature of 68
°
F.
2.2
Working principle
An electric motor drives a fan and fuel pump.
The pump draws the fuel from the tank to a
magnetic valve. The fan blows air into and
around the combustion chamber.
The magnetic valve opens 12 seconds after
switching on the heater and the fuel flows into
the nozzle.
A spark between the electrodes ignites the
atomised fuel and starts a flame. The light
from the flame activates a photocell. After the
safety time the ignition switches off. The
magnetic valve closes when you switch off
the heater, or as a result of a fault, the flame
stops.
The fan runs until a thermostat switches the
fan off: the cooling cycle is complete.

GETTING STARTED
3.1
Remove packaging
1. Remove the packaging from the heater.
2. Attach the handle and the bumper to the
heater (only for ITA 75).
3.2
Installation
1. Make sure that the heater is placed
horizontally.
2. Fill the tank with fuel.
3. Make sure there is sufficient distance
between the wall and the air inlet.
Minimum distance is 4 ft.
4. Make sure that the heated air can flow
without obstruction. Minimum distance
from outlet to an obstacle is 7 ft.
Caution
Use only No. 1 fuel, No. 2 fuel or
Diesel.
Caution
•
Be careful when you fill the tank.
Remove any spilled oil from the
heater and the ground.
•
Gas oil tends to thicken at low
temperatures. This can block the
filters. Add a maximum of 15%
paraffin to the fuel at
temperatures below -20
°
F, or
keep the fuel frost-proof, or use
tank heating (optional).
