Maintenance Procedures
6-Month Maintenance
Check Water and Gas Piping
1. Remove the appliance front jacket panel and per-
form 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
appliance following procedures on page 7. Call a
qualified service technician.
2. Visually inspect for leaks around the internal appli-
ance water connections and around the heat
exchanger. Visually inspect the external system pip-
ing, circulators, 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 CHALLENGER
installation manual. The discharge line must be ter-
minated so as to eliminate possibility of severe
burns or property damage should the valve dis-
charge.
WARNING
WARNING
2. Read the temperature 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 appliance down per the instructions on page
7. Call a qualified service technician to inspect
the valve and system.
