MAINTENANCE
Correct and regular use and maintenance of the unit heater allows an efficient operation, a minimum
consumption, as well as a long life.
These interventions must be realised by a qualified person.
THE MAINTENANCE MUST BE DONE WITH THE DEVICE COLD, WITH THE GAS AND
ELECTRICITY SUPPLIES CUT OFF.
The heaters used for poultry houses must be cleaned and maintained more frequently.
It is necessary to clean the device each time a
change
is
made to a
new batch! It is also required to
check the combustion at least twice a year.
Check the proper functioning of all safety devices and check that all screws are correctly tightened.
Heat exchanger, smoke extractor and venturi :
To access to the heat exchanger, dismount the smoke box and the burner. Inspect the stat of the tubes
inside, and if it necessary, clean and sweep it. Make sure to replace all damaged seals during this
operation. Unscrew and open the blowing grille and the upper access door to clean the heat exchanger.
Clean the exhaust fan and the venturi with a soft cloth and/or compressed air.
Gas burner:
Dismantle the burner, check the burner ramp state and the nozzles and clean it.
Check the state of the ionization sensor and ignition electrode, their position in relation the burner ramp and
change them if it is necessary.
Gas filter :
Dismantle the dirty cartridge and clean it with compressed air.
Flue pipe :
Dismantle the pipe, sweep it and check leaks.
Blowing fan:
Before cleaning the device, disconnect the
“
Harting
”
electrical plug of the fan(s) before opening the door. If
it is needed, it is possible to remove completely the door to avoid any water projection when you clean the
heat exchanger or the farm. Clean the fan(s)
with compressed air, never use a high
-
pressure
jet
of
water
.
Body and grilles :
Clean it using a duster.
Outside of the heat exchanger:
The heat exchanger can resist to a high pressure cleaner
and can be cleaned with clean water,
without addictive
.
After cleaning, make sure to dry properly the device
to
avoid stagnant water, that can create an oxidation in
reaction with volatile compounds into the farm.
The grill can be remove to facilitate the access to the
exchanger and clean it. Make sure to do not spray the
exchanger from the front, keep the head of high pressure
jet on the side to allow a good angle to clean the heat
exchanger. The water will flow towards the lower access
door.
Be careful, during the cleaning, do not spray through
the crimping base of the exchanger,
there is a risk of
infiltration into the combustion circuit.
CAUTION:
Do not clean the burner compartment or the fan(s) with high
-
pressure jet
of
water!
Do not get wet the electrical parts, ELECTRICAL HASARD !
Do not spray through the fan(s).
