Flueing Guidelines - Rinnai INFINITY N56kWi Installation Manual

Flueing guidelines

Combustion air provided to the system should not be taken from any area that may produce a
negative pressure (i.e exhaust fans, powered ventilation fans etc.). Room combustion air requires
compliant louvres in a plant room door or wall, refer AS/NZS 5601.1:2013 for more information.
For appliance and user safety NEVER use Rinnai flue components with other manufacturer's water
heaters.
