Maintenance procedures [Every 6 Months]
- Check the boiler piping (gas and water)
Visually inspect for leaks around internal water
piping. Also inspect external water piping,
circulators, relief valve and fittings. Immediately
call a qualified service technician to repair any
leaks. Leaks must be fixed by a qualified service
technician immediately.
Failure to comply with this instruction could result in
severe personal injury, death or substantial property
damage.
- Check the operate relief valve
WARNING
Leaks must be fixed by a qualified service technician
immediately. Failure to comply with this instruction
could result in severe personal injury, death or
substantial property damage. This discharge line
must be installed by a qualified heating
installer or a service technician.
Before proceeding the procedures, verify that relief
valve outlet has been piped to a safe place of
discharge, avoiding any possibility of scalding from
hot water. If water flows freely, release the lever
and allow the valve to seat. Watch the end of the
relief valve discharge pipe to ensure that the valve
does not weep after the line has had time to drain.
If the valve weeps, lift the seat again to attempt
to clean the valve seat. If the valve continues to
weep, contact your qualified service technician for
inspecting the valve and system. If water does not
flow from the valve even though you have lifted the
8.1 Annual startup & general maintenance
lever completely, the valve or discharge line may be
blocked. Shut down the Boiler immediately. Call your
qualified service technician to inspect the boiler and
system.
- Check the burner state
You can clean the exterior of burner. However, if you
need to clean the inside of the burner stage, you
should call an expert.
