Abstract: A water heater including a water container; a combustion chamber containing a main burner and a pilot burner positioned to heat water in the water container and having a side wall; a main burner fuel supply line adapted to connect between a fuel control valve and a main burner; a pilot fuel supply line adapted to connect between the fuel control valve and a pilot burner; a heat sensor line connected to a heat sensor and adapted to connect to the fuel control valve and positioned to sense heat from the pilot burner; an igniter line connected to an igniter positioned proximate the pilot burner and connected to an igniter initiator; and a removable plate sealed to the combustion chamber through which the main burner fuel supply line, the pilot fuel supply line, the heat sensor line and the igniter line pass in a sealed condition.

Abstract: A power burner type gas-fired water heater has a fuel supply manifold which is mounted within a sealed plenum box and supplied with gas from a valve externally mounted on the plenum box and coupled to the manifold via a flex hose disposed within the plenum box and removably connected to the gas valve. By simply removing an access wall portion of the plenum box, uncoupling the flex hose from the gas valve and disconnecting the manifold from associated support structure within the plenum box, the manifold may be removed from the plenum box for replacement of the fuel supply orifices carried by the manifold. This facilitates the field modification of the water heater's input rate and/or fuel type.
Abstract: A water heater including a water tank, a combustion chamber beneath the tank, a gas burner in the combustion chamber, an air plenum upstream of the combustion chamber, a flame arrestor located such that air in the air plenum passes through the flame arrestor to reach the combustion chamber, and a flue extending upwardly from the combustion chamber and through the water tank.

Abstract: A water heater baffle having an inlet and an outlet for the passage of water therethrough, the baffle being arranged to force the water entering the baffle through a labyrinth before exiting the baffle in a direction substantially 90° to its general flow of entry into the baffle.
Abstract: A water heater including a water container; a combustion chamber located adjacent the container, the combustion chamber having a floor portion with an opening; a conduit extending upwardly from and being substantially sealed to the opening; a burner located inside the combustion chamber; and a flame trap positioned across the conduit, the flame trap permitting ingress of air and/or extraneous gases into the combustion chamber and prevent egress of flames from the structure.
Abstract: A register for use in conjunction with kraft recovery boilers or bark-fired boilers utilizes a pair of shaped damper foils to reduce turbulence and induce laminar flow of air from an associated windbox through a port in the boiler. The foils are mounted for constant minimal separation from an exit nozzle to reduce transitional discontinuities which induce turbulence. A curved plenum is also provided to reduce internal turbulence within the plenum.
