Hazard definitions
The following defined terms are used throughout this manual to bring attention to the presence of hazards of various
risk levels or to important information concerning the life of the product.
Indicates presence of hazards that will cause severe personal injury, death or substantial property
damage.
Indicates presence of hazards that can cause severe personal injury, death or substantial property
damage.
Indicates presence of hazards that will or can cause minor personal injury or property damage.
Indicates special instructions on installation, operation or maintenance that are important but not

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 accumula-
tion 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.
