8.1 Annual Startup & General Maintenance (continued)
- Check the air vent
If the air vent valve seems to work freely without
leaking, replace cap “A” by twisting all the way on.
Loosen cap “A” one turn to allow vent to operate.
If vent does not operate correctly, replace the vent.
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
Before proceeding this startup procedure, verify
that the 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.
- 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.
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.
A
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 Boiler
immediately. Call your qualified service technician to
inspect the boiler and system.
8.2 Flushing the Boiler

authorized technician or licensed professional. Keep
in mind that improper maintenance can void your
warranty.
1. Disconnect electric power to the boiler.
2. Close the shutoff valves on both hot water outlet
and cold water inlet lines. (V1 & V2)
3. Connect one hose “D1” to the valve “V3” and
place the free end in the bucket. Connect one
