Abstract
An air flow modulating device comprising a flapper, a mount and a conduit. The conduit may be T-shaped and may be attached to an intake conduit of a sealed combustion condensing appliance, or other appliance having an air intake conduit, through a first portion of T-shaped conduit. The mount may be connected to a second portion of T-shaped conduit and the flapper may rotate between an open position and a closed position about an axle of the mount. The device operates to allow for a sealed combustion condensing appliance to immediately intake interior air when an exterior air source is obstructed, limited or reduced, or in response to changes in air pressure due to uncontrollable natural forces.
Claims20
An air flow modulating device for a sealed combustion condensing appliance, said device comprising:
- a first air flow intake path configured to communicate with an air source exterior to a structure containing the sealed combustion condensing appliance;
- a second air flow intake path configured to communicate with an air source interior to the structure containing the sealed combustion condensing appliance and further in communication with said first air flow intake path at a position prior to combustion within the sealed combustion condensing appliance;
- and
- a valve in communication with said second flow path, said valve adjusts from a first position corresponding to a first pressure level within said first air flow intake path to a second position corresponding to a second pressure level within said first air flow intake path.
An air flow modulating device for a sealed combustion condensing appliance of the type having a non-metal air intake conduit, said device comprising:
- a first plastic conduit portion defining a first combustion air flow intake path configured to communicate with an air source exterior to a structure containing the sealed combustion condensing appliance;
- a second plastic conduit portion defining a second combustion air flow intake path configured to communicate with an air source interior to the structure containing the sealed combustion condensing appliance and further in communication with said first combustion air flow intake path;
- and
- a valve in communication with said second flow path, said valve configured to automatically open from a first closed position corresponding to a first pressure level within said first combustion air flow intake path to a second open position corresponding to a second pressure level within said first air flow intake path.
An air flow modulating device for a sealed combustion condensing appliance of the type having a non-metal air intake conduit in communication with an intake air source exterior to a structure containing the sealed combustion condensing appliance and an exhaust conduit in communication with an exterior of the structure for release of exhaust from the appliance, said device comprising:
- a first air flow intake path configured to communicate with the air intake source exterior to the structure containing the sealed combustion condensing appliance;
- a second air flow intake path configured to communicate with an air source interior to the structure containing the sealed combustion condensing appliance and further configured to communicate with said first air flow intake path at a position prior to entry of air from said second air flow intake path into a combustion area of the appliance;
- and
- a valve in communication with said second flow path, said valve adjusts from a first position corresponding to a first pressure level within said first air flow intake path to a second position corresponding to a second pressure level within said first air flow intake path.
