Advice: Lots of farmers use a second set of dust filters. They replace the dusty ones directly with the

clean ones and clean the filters outside the barn to avoid unneeded disturbance of the animals.

Internal cleaning

The internal part of a heater can be cleaned with compressed air and with a tube brush. If needed do

this every day. First clean the outside of the burner globe. Then the inside of the venturi and burner

tube via the dust filter connection. Repeat this 3 times to be sure that all the dust is removed.

Water

Never wash the heater with water when it is

operating or still hot. Do not clean the heater

with steam or chemicals or high-pressure jets.

The lifetime of the burner globes will go down

in those cases. It is allowed to wash the inside

of the venturi and burner globes with low

pressure (warm)water from a normal hose (so

not pressurized) to remove greasy dust. Be

sure that the burner is completely dry before

using it again. Also make sure that the gas

safety device and injector remains dry all the

time.

High fire

The lifetime of infrared heaters in a dusty environment will be extended in case these heaters are

operated on high fire every 12 to 24 hours for minimal 15 minutes. This burns off dust in the burner that

accumulates during low-fire operation. This is only needed in case heaters operate on lower setting for

a longer period. When a barn computer is used for heating and ventilation, it will be easy to modify the

program to add a 15 minutes high fire operation every day. In case a mechanical thermostat (T) is used

a solution can be to put the sensor for 15 minutes in a bucket with cold water during daily inspection of

the barn.

Consumable parts

Thermocouples (64-68) and the magnet unit (56) inside the gas safety device are the most important

parts that maybe requires replacement during normal operational life. See the Parts List for more

information.

Replacement thermocouple and magnet unit

Remove the thermocouple (64-68) by unscrewing the nut M8 at

the gas safety device.

Unscrew the nut (55) at the gas safety device (51-54).

Remove the broken magnet unit (56) and replace by a new one.

Replace the nut (55) and close carefully (firmly but not excessive)

to avoid gas leakage.

Loosen nut M8x1 (70) one turn, bend the thermocouple straight

again and turn it out of the top plate (8, 9)

Screw nut M8x1 (70) on the new thermocouple and turn

thermocouple (still straight) in the top plate (8, 9) until the depth as indicated in the drawing (Global

5 = 25 mm, Global 10 = 22 mm). Tighten nut M8x1 (70) to secure the thermocouple in place.

Bend the new thermocouple in the identical shape as the old one the and screw the thermocouple

nut M8 in nut (55) of the gas safety device (51-54). Hand-tight first and then an additional 1/6 turn.

Carefully check the gas safety device for gas leakage before taking back into operation.

Conversion instructions

Conversion shall be done by a qualified installer only. To convert a heater from one gas or gas pressure

to another gas or gas pressure, take the following actions.

Consult the technical table on the last page and contact the manufacturer or dealer for the parts

needed. (new injector (31, 32) new venturi (22), new thermostat body (46) or solenoid body (41, 42)

and a new dataplate).

Replace the parts by new ones. Use a proper gas sealant to avoid gas leakage and seal the new

parts.
