- Check the pressure 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, 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 lever completely, the valve
or discharge line may be blocked. Shut down the
Combination boiler immediately. Call your qualified
service technician to inspect the combination 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 a qualified service technician.
