Please read before proceeding
Hazard Definitions
The following defined terms are used throughout these Instructions to bring attention to the presence of hazards
of various risk levels, or to important information concerning the life of the product.
When servicing boiler —
•
To avoid electric shock, disconnect electrical supply before performing maintenance.
•
To avoid severe burns, allow boiler to cool before performing maintenance.
•
The boiler contains fiberglass materials. Use care when handling these materials per instructions on page
11 of this manual.
Boiler operation —
•
Do not block flow of ventilation air to boiler. Will cause components to overheat.
•
Should overheating occur, do not disconnect electrical supply to circulator. Instead, shut off the electrical
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 that has been under water.
Boiler water —
•
Do not use petroleum-based cleaning or sealing compounds in boiler system. 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 buildup in section 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.
Glycol — potential fire hazard —
All glycol is flammable when exposed to high temperatures. If glycol is allowed to accumulate in or around
the boiler or any other potential ignition source, a fire can develop. In order to prevent potential severe
personal injury, death or substantial property damage from fire and/or structural damage:
•
Never store glycol of any kind near the boiler or any potential ignition source.
•
Monitor and inspect the system and boiler regularly for leakage. Repair any leaks immediately to prevent
possible accumulation of glycol.
•
Never use automotive antifreeze or ethylene glycol in the system. Using these glycols can lead to hazardous
leakage of glycol in the boiler system.
