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 concern- ing the life of the product.

Indicates presence of hazards that will cause severe personal injury, death or substantial property damage if ignored.

Indicates presence of hazards that can cause severe personal injury, death or substantial property damage if ignored.

Indicates presence of hazards that will or can cause minor personal injury, death or substantial property damage if ignored.

Indicates special instructions on installation, operation or maintenance that are important but not related to personal injury.

Read before proceeding:

Read all instructions before installing. Failure to follow all instructions in proper order can cause severe personal injury, death or substantial property damage.

Do not use petroleum-based cleaning or sealing components in boiler system. Severe damage to system components can result, causing sub- stantial property damage.

Propane boilers only — Your propane supplier mixes an odorant with the propane to make its presence detectable. In some instances, the odorant can fade and the gas may no longer have an odor.

■Propane gas can accumulate at floor level. Smell near the floor for the gas odorant or any unusual odor. If you suspect a leak, do not attempt to light the burner.

■Use caution when attempting to light a propane burner (or pilot burner). This should be done by a qualified service technician, particularly if flame outages (or pilot outages) are common.

■Periodically check the odorant level of your gas.

■Inspect boiler and system at least yearly to make sure all gas piping is leak-tight.

■Consult your propane supplier regarding installation of a gas leak detector. There are some products on the market intended for this purpose. Your supplier may be able to suggest an appropriate device.
