1. A pre-mix burner system comprising:
- a manifold having an air input, a fuel input and a mixture output; and
a housing enclosing the manifold; and
wherein;
the housing has one or more air input slots, an input opening for the fuel input to the manifold, and an output opening for the mixture output of the manifold;
a path for a flow of air goes through the one or more input slots proximate to an output portion of the manifold, over an external surface of the manifold from the output portion of the manifold to the air input at an input portion of the manifold; and
the flow of air following the path is for changing a temperature of the manifold and/or the air of the flow to the air input of the manifold.

Abstract
A system having a pre-mix burner manifold in a housing that may permit air to be drawn through slots in the housing to flow over an external surface of the manifold. The flow of air may maintain a temperature of the manifold lower than a temperature that the manifold might have without the flow. The manifold may be attached to a burner and heat exchanger.

10. An approach for affecting a temperature of a manifold, comprising:
-
drawing a first air through one or more openings of a housing into the housing and over a surface of a pre-mix burner manifold; further drawing the first air through an input of the manifold and into the manifold; drawing fuel into the manifold for obtaining an air and fuel mixture; and drawing the air and fuel mixture through the manifold and one or more inshot holes to a burner; and wherein the first air drawn over the surface of the manifold is for changing the temperature of the manifold and/or the air and fuel mixture. - View Dependent Claims (11, 12, 13, 14, 15)

16. A premix burner manifold comprising:
-
a manifold having an input port and one or more output ports; a fuel connection at the input port; an air input at the input port; a housing, having one or more input slots, enclosing the manifold having the input port and output ports; and wherein; air can be drawn through the one or more slots into the housing, over the manifold, through the input port, and through the manifold and the one or more output ports; and the fuel connection permits fuel to be provided into the manifold to form a mixture with the air drawn through the manifold. - View Dependent Claims (17, 18, 19, 20)
