ƽ CAUTION
ƽ CAUTION
Do not use “homemade cures” or “boiler
patent medicines”. Serious damage to the
boiler, personnel, and/or property may
result.
• Do not block fl ow of combustion or ventilation air to
the boiler.
• Should overheating occur or gas supply fail to shut off,
do not turn off or disconnect electrical supply to
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 fl ooded appliance can be
extensive and present numerous safety hazards. Any
appliance that has been under water must be replaced.
Boiler water –
• Thoroughly fl ush the system (without boiler connected)
to remove sediment. The high-effi ciency heat exchanger
can be damaged by build-up or corrosion due to sediment.
• Continual fresh make-up water will reduce boiler life.
Mineral buildup in the heat exchanger reduces heat
transfer, overheats the stainless steel heat exchanger,
and causes failure. Addition of oxygen carried in by
makeup water can cause internal corrosion in system
components. Leaks in boiler or piping must be repaired
at once to prevent makeup water.
Freeze protection fl uids –
• NEVER use automotive antifreeze. Use only inhibited
propylene glycol solutions, which are specifi cally
formulated for hydronic systems. Ethylene glycol is
toxic and can attack gaskets and seals used in hydronic
systems.
