Be aware that if not cared for properly, a 20 gal Storage Water Heater, can explode with enough
energy to rocket through a three story building, scald all those within, and cause structural collapse and fire.
A room containing a Water Heater should stay properly ventilated.
Deadly Carbon Monoxide will be produced if the Burner does not have adequate air circulation in order to prevent
incomplete fuel combustion.
Drain water from your tank two to four times a year. When water is heated, calcium carbonate settles to the
bottom of the tank. This sediment reduces the efficiency of your water heater, as well as its storage capacity and
eventually its lifespan.
A Storage Water Heater should be installed on a solid floor or on a structure designed to safely support a
Water Heater completely filled with water. Clearance measurements must comply with all jurisdictional requirements.
