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.
Boiler operation –
• Do not block flow of combustion or ventilation air to
the 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. 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 the
circulator. 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.
The possible damage to a flooded appliance can be
extensive and present numerous safety hazards. Any
appliance that has been under water must be replaced.
Boiler water –
• Thoroughly flush the system (without boiler
connected) to remove sediment. The high-efficiency
heat exchanger can be damaged by build-up or
corrosion due to sediment.
• Do not use petroleum-based cleaning or sealing
compounds in the boiler system. Gaskets and seals in
the system may be damaged. This can result in
substantial property damage.
• Do not use “homemade cures” or “boiler patent
medicines”. Serious damage to the boiler, personnel,
