Inspections and maintenance
Second phase – Cleaning.
- Take out the gaskets and burners.
- Dry clean the burners using compressed air and operating from the
"flame side".
- Visually check the state of the welding on the angulars and burner
mesh.
The burner gaskets must be replaced every time
cleaning operations are carried out.
- Wash the combustion chamber with water being careful not to get
the electrical cables wet.
- During this operation is necessary to make sure that the condensate
exhaust pipe is always unobstructed so that the wash water does not
leak out from the inspection opening.
- Blow the combustion chamber with compressed air to remove any
dirt that is still attached to the studs.
- When the elements have been washed make sure that the condensate
drain trap is unobstructed: clean if necessary.
- Inspect the exhaust evacuation pipe and the flue.
Third phase - Reassembly.
- Once the body and/or burners have been cleaned, put the burners
back in their places.
- Put the
new graphite gaskets in place.
Proceed in the reverse order for reassembly, being
careful to tighten the screws that clamp the mixer
unit/fans to the body, at a torque of 13 Nm.
ATTENTION
IT IS NECESSARY TO CHANGE THE SEALING
GASKETS ON EACH BURNER AT EVERY
MAINTENANCE OPERATION.
- Prior to ignition, make sure the condensate drain trap is full of water.
- Before opening the gas supply valve make sure that the previously
loosened gas fitting is firmly tightened. In order to do so open the
valve and check the seal using soapy water.
- As a burner is being ignited, immediately check the seal between each
single gas valve and relative premixing chamber.
- Perform a combustion analysis and check the parameters.
- Make sure that all of the previously opened gas pressure points are
closed.
