Operation

New heaters

New heaters need a cleaning period before they are ready for operation. Turn the ventilation to maximum

position or place the heaters outside in the open air. Fire the heaters for at least two hours on full capacity

to burn-off oily and greasy remnants of the production. Make sure that after two hours all smoke and

smell is disappeared. The smoke and smell can be unhealthy, so keep animals and human beings away

till the heaters and the environment air is clean.

Ignition of the heater

Always ignite a heater on maximum heat input setting. After a pre heating time of 60 seconds the heater

can be adjusted to the desired heat input setting.

Warning: after a heater is extinguished (intentionally or unintentionally) wait always for 3 minutes before

(re)ignition. This is a worldwide safety rule and intended to ventilate unburned gases away and to leave

enough time for the thermocouple device to close.

AP-(1,2,3)-F, -FT versions:

1) Open all gas taps (and turn the thermostat or gas pressure

regulator on maximum).

2) Keep a flame of a BBQ lighter (or long match) in the ignition hole

of the burner tube.

3) Press the knob of the gas safety device and wait for 10-25

seconds after ignition before releasing the knob.

4) The burner will stay on now.

5) Repeat al steps again in case the burner directly extinguishes.

Heat regulation of the heater

AP-(1,2,3)-F version:

The heat input of this heater can only be changed by adjusting the pressure of the gas supply. Check

the gas supply pressure information on the data plate of the heater for the minimum and maximum

values. If only one pressure is mentioned, adjustment is not possible and only continuous operation or

on-off operation is allowed.

AP-(1,2,3)-FT version:

Make sure that the gas supply pressure remains constant at the value

indicated on the data plate. Adjust the heat input by setting the

thermostat knob at the desired value. Note that the temperature on the

ground will be several degrees higher than at the sensor. So, use the

setting on the thermostat knob as a rough guideline and always check

the real temperature on the ground

Extinguishing the heater

AP-(1,2,3)-F, -FT versions:

Close the gas tap or the central gas supply. The burner will extinguish now. The thermocouple safety

valve will close after 60 seconds.

Visual examination of the flame

Check after every ignition (and also during regular barn inspection) if a heater still burns correctly. The

flame shall remain always inside the burner tube. The burner tube shall be equal red/orange in high

firing position and having a blue flame.

A burner does not operate well in case there is a (green)-blue cloud inside the reflector and/or a

(green)blue flame tongue is coming out the exhaust hole in the reflector. Soot deposit on the reflector

and yellow flames are also a sign of bad functioning and are not allowed. Cleaning will solve these

problems in most cases. Note that yellow tipping in low fire is allowed.

In high fire position, the flame makes a soft roaring noise. In case the burner makes a loud roaring noise

and the burner tube does not become equal red/orange, the venturi gauze is damaged and the flame is

burning inside the venturi tube (back firing). The venturi tube becomes very hot now at the beginning of

the venturi. Directly extinguish the burner and replace the damaged venturi tube and gauze by a new

one.
