Page 14 INSTALLATION CONSIDERATIONS LOCATING THE WATER HEATER Also, the water heater must be located and/or protected so it is not subject to physical damage by a moving vehicle. Carefully choose a location for the new water heater. The placement is a very important consideration for the safety of the occupants in the building and for the most economical use of the water heater.
Page 15 • Do not apply insulation to the top of the water heater, as this will interfere with safe operation of the blower assembly. • Do not cover the control system LCD on top of the water heater. • Do not cover the outer door, thermostat or temperature & pressure relief valve.
Page 16 FRESH AIR OPENINGS FOR CONFINED SPACES UNCONFINED SPACE The following instructions shall be used to calculate the size, number and placement of openings providing fresh air for combustion, An Unconfined Space is one whose volume IS NOT LESS THAN ventilation and dilution in confined spaces.
