Maintaining the heater
It is recommended to have the heater checked and serviced by a service technician every
year to guarantee reliable and safe operation. Heaters used in poultry sheds must be serviced
more often and more extensively due to high levels of dust and dirt in these types of spaces.
6.1 General maintenance
The heater must be free of electricity during servicing. Remove the plug from the socket outlet.
Do not use water when cleaning the unit.
Perform the following activities during general maintenance:
•
Open the body access panel and especially clean the body, fan blades, fan motors, vane
switch, maximum thermostat and swirl ring.
•
Grease any parts and bolts that are loosened regularly for maintenance.
•
Check whether the wiring, nuts and bolts are all properly tightened.
•
Open the fuel valve and check whether the heater and the hoses are tight and leak free
and do not contain air.
6.2 Extensive maintenance in a poultry shed
The heater must be free of electricity during servicing. Remove the plug from the socket outlet.
Do not use water when cleaning the heater.
Clean and check heaters used in poultry sheds after every shed clean-out and before spreading
sawdust. To do this, carry out the following actions:
1. Use compressed air to blow the parts clean, especially the inside and outside of the body,
fan blades, fan motor, vane switch.
2. Remove all dust from the motor as the layer of dust acts as insulation, which can cause
the motor to overheat.
3. Use a brush to remove any caked on dust.
4. Clean the burner unit (refer to Cleaning the burner unit).
5. Put the Power back on and let the heater heat for a while so that if any dust particles have
remained behind, they are now burnt.
6. Stop heating and cover the heater once it has fully cooled off.
7. Make sure the heater is free of electricity by removing the plug from the socket outlet.
8. Disinfect the poultry shed and spread the sawdust.
9. Remove the cover from the heater.
To ensure the instructions below are carried out safely, it is recommended having these
carried out exclusively by a service technician.
Perform the following checks after cleaning the heater:
•
Open the fuel valve and check whether the heater and the hoses are tight and leak free and
do not contain air.
•
If the heater has been moved, check whether the hoses are connected properly.
Connections that slip off or that are improperly mounted can create a fire hazard.
•
Check that the wiring is properly secured.
Finally, carry out all the checks that are performed during heater installation (refer to Performing
checks :
1. Measure the pump pressure;
2. Measure combustion values;
3. General heater operation.
Place and close the access panels once you have completed all checks. The heater may now
be used again.
