Failure to adhere to the guidelines on this page can result in

Boiler service and maintenance —
• To avoid electric shock, disconnect electrical supply before
performing maintenance.
• To avoid severe burns, allow boiler to cool before performing
maintenance.
• You must maintain the boiler as outlined in the manual and have the
boiler started up and serviced at least annually by a qualified
service technician to ensure boiler/system reliability.
Boiler operation —
• Do not block flow of combustion or ventilation air to boiler. This boiler
is equipped with a control which will automatically shut down the boiler
should air or vent be blocked. If vent or air blockage is easily accessible
and removable, remove it. The boiler should attempt to restart within an
hour. If blockage is not obvious or cannot be removed, have the boiler
and system checked by a qualified service technician.
• Should overheating occur or gas supply fail to shut off , do not
turn off or disconnect electrical supply to pump. Instead, shut off the
gas supply at a location external to the appliance .
• Do not use this boiler if any part has been under water .
Immediately call a qualified service technician to inspect the boiler and to
replace any part of the control system and any gas control, which has
been under water.
Boiler water —
• DO NOT use petroleum-based cleaning or sealing compounds in
boiler system. Water seal deterioration will occur, causing leakage between
sections and damage to heating system components. This can result in
substantial property damage.
• DO NOT use " homemade cures " or " boiler patent medicines ".
Serious damage to boiler, personnel and/or property may result.
• Continual fresh makeup water will reduce boiler life . Mineral
build-up in sections reduces heat transfer, overheats cast iron, and causes
section failure. Addition of oxygen and other gases can cause internal
corrosion. Leaks in boiler or piping must be repaired at once to prevent
makeup water.
• Do not add cold water to hot boiler . Thermal shock can cause
sections to crack.
