CHAPTER 3 - MAINTENANCE PROCEDURES
3.4. 6-Month Maintenance
3.4.1 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 9. If gas odor or a
leak is detected, immediately shut down the unit
following procedures on page 9. Call a qualied ser-
vice 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 ttings. Immedi-
ately call a qualied service technician to repair any
leaks.
Have leaks fixed at once by a qualified service
technician. Failure to comply can result in
substantial property damage, serious injury,
or death.
3.4.2 Operate Pressure Relief Valve
1. Before proceeding, verify that the relief valve outlet
has been piped to a safe place, avoiding any possi-
bility of scalding from hot water.
To avoid water damage or scalding, a dis-
charge line must be connected to the relief
valve outlet and directed to a safe place of
disposal. This discharge line must be in-
stalled by a qualified service technician in
accordance with the PRESTIGE installation
manual. The discharge line must be termi-
nated so as to eliminate possibility of severe
burns or property damage should the valve
discharge. Failure to comply can result in
substantial property damage, serious injury,
or death.
2. Read the pressure gauge to ensure the system is
pressurized. Lift the relief valve top lever slightly,
allowing water to relieve through the valve and dis-
charge piping.

3. If water ows freely, release the lever and allow the
valve to seat. Watch the end of the relief valve dis-
charge 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 clean the valve seat. If
the valve does not properly seat and continues to
weep afterwards, contact a qualied service techni-
cian to inspect the valve.
4. If water does not ow from the valve when you lift
the lever completely, the valve or discharge line
may be blocked. Immediately shut the unit down
per the instructions on page 9. Call a qualied ser-
vice technician to inspect the valve and discharge
line.
3.4.3 Check Carbon Monoxide Detectors
Verify that at least two (2) carbon monoxide detectors
are installed and operating properly. One must be in-
stalled in the mechanical room where the PRESTIGE is
located and another installed in the living area outside
the bedroom(s).
Contact a qualied service technician if carbon mon-
oxide detectors are not installed or operating properly.
