SECTION V: WATER CONNECTIONS WARNING Failure to install and maintain a new, listed pressure relief valve will release the manufacturer from any claim, which might result from excessive temperature and pressures. Keep clear of the pressure relief valve discharge line outlet. The discharge may be hot enough to cause scald injury. - Page 12 Special controls are available from your Laars supplier for operating more than one water heater together. These controls stage the operation of the water heaters for the flow rates and control the amount of flow through each water heater.

SECTION IX: MAINTENANCE WARNING Always turn off the electrical power supply, the manual gas valve, and the manual water control valve whenever servicing this appliance. KEEP THE APPLIANCE AREA CLEAR AND FREE FROM COMBUSTIBLE MATERIALS, GASOLINE, AND OTHER FLAMMABLE VAPORS AND LIQUIDS! Do not block the air inlet openings on the front panel or flue exhaust vent. - Page 36 WARNING Before manually operating the valve, make sure that a drain line has been attached to the valve to direct the discharge to an open drain. Failure to take this precaution could mean contact with extremely hot water passing out the valve during this checking operation. FLUSHING PROCEDURE FOR LIME SCALE REMOVAL FROM HEAT EXCHANGER The amount of calcium carbonate (lime) released from water is in direct proportion to water temperature and usage.
