6-Month Maintenance
Check water and gas piping
1.
Remove the boiler front jacket panel and perform a
gas leak inspection per steps 1 through 6 of the
Operating Instructions on page 7. If gas odor or
leak is detected, immediately shut down the unit
following procedures on page 7. Call a qualified
service technician.
2.
Visually inspect for leaks around the internal boiler
water connections and around the heat exchanger.
Visually inspect the external system piping, circula-
tors,
and
system
components
and
fittings.
Immediately call a qualified service technician to
repair any leaks.
Have leaks fixed at once by a qualified service tech-
nician. Failure to comply could result in severe per-
sonal injury, death or substantial property damage.
Operate Pressure Relief Valve
1.
Before proceeding, verify that the relief valve
outlet has been piped to a safe place of dis-
charge, avoiding any possibility of scalding from
hot water.
To avoid water damage or scalding due to valve
operation, a discharge line must be connected to the
relief valve outlet and directed to a safe place of dis-
posal. This discharge line must be installed by a
qualified service technician or heating / plumbing
installer in accordance with the PRESTIGE installa-
tion manual. The discharge line must be terminated
so as to eliminate possibility of severe burns or
property damage should the valve discharges.
WARNING
WARNING
2.
Read the temperature display and pressure
gauge to ensure the system is pressurized. Lift
the relief valve top lever slightly, allowing water to
relieve through the valve and discharge piping.
3.
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 lever again to
attempt to clean the valve seat. If the valve
does not properly seat and continues to weep
afterwards, contact a qualified service techni-
cian to inspect the valve and system.
4.
If the water does not flow from the valve when
you lift the lever completely, the valve or dis-
charge line may be blocked. Immediately shut
the unit down per the instructions on page 7.
Call a qualified service technician to inspect the
valve and system.
