location where gas and water can accumulate.
• Do not have the vent terminal pointing toward any operating window, door, or
opening into a building
• Do not install the water heater next to any source of airborne debris, such as a
clothes dryer and a vent that can cause debris to be trapped inside the combustion
chamber, unless the system is direct-vented

to safety issues. If you install the water heater in an attic:
• Make sure the water heater will have enough combustion air and proper
ventilation

responsible for any water damage that may occur If you install a drain pan under the
water heater, ensure that it will not restrict the combustion air flow
