MOUNTING
The water heater should be mounted to the floor following applicable architectural and local code requirements or accepted standards for the specific site and model purchased. In areas prone to seismic activity, it is recommended that the water heater be mounted to the floor according to recommended procedures for the site. In some geographic areas, additional strapping or braces may be required, consult local codes for specific requirements. Proper mounting will help to make the water heater less susceptible to seismic damage.
