WARNING
Failure to properly pipe boiler may result in improper operation and damage to boiler or structure.
Install boiler so that the gas ignition system components are protected from water (dripping, spraying,
rain, etc.) during appliance operation and service (circulator replacement, etc.).
Oxygen contamination of boiler water will cause corrosion of iron and steel boiler components, and can
lead to boiler failure. Burnham Commercial’s Standard Warranty does not cover problems caused by
oxygen contamination of boiler water or scale (lime) build-up caused by frequent addition of water.
Do not ll boiler with softened water to prevent chloride contamination.
