DIRECTIONS FOR USE
Hot Water Boiler Systems: Mix Boiler Solder with hot water and
pour into hot boiler water. Can be poured directly into boiler. Never
pour Boiler Solder into a cold boiler.
Note: Not for use in domestic water systems.
Steam Heating Systems: After some pressure has been obtained,
turn off heat and allow pressure to drop down sufficiently so that the
safety valve can be removed without burning hands. Mix Boiler
Solder with hot water and pour into boiler or pour product directly
into system. Replace safety valve and allow boiler to make steam,
building up pressure as high as the safety limits permit. If the leak is
severe, lower boiler water below the leak before adding Boiler
Solder. Then refill boiler and make steam.
Boiler Liquid and Boiler Solder can be used in the same system
but the combined dosage should not exceed recommended
amounts.
Larger holes or cracks in areas not exposed to flames can first be
filled with Hercules Pro poxy
