## Abstract

A furnace is disclosed. The furnace may include an enclosure having a vertical support column formed by a heat exchanger compartment panel and a blower compartment panel. The furnace may include a window assembly having venting openings hidden by a viewing window. The furnace may also include a rail to support a removable heat exchanger system. The furnace may further include a wire retaining fin assembly to retain a wire. A heat exchanger header design including features to retain a sealant is also disclosed.

## Claims

### Claim 1

A furnace, comprising
a burner system;
a heat exchanger system; and
a blower system,
wherein the heat exchanger system includes:
a heat exchanger;
a heat exchanger support, attached to a header of the heat exchanger; and
a first rail, located on a first side wall of the heat exchanger system; and
a second rail, located on a second side wall of the heat exchanger system;
wherein the heat exchanger support includes a notch configured to engage the rail,
the first side wall is opposite the second side wall, and
the heat exchanger support is configured to be slidable along the first and second rails.

### Claim 2 (depends on 1)

The furnace of claim 1, wherein at least one of the first rail and the second rail includes one or more flanges, and at least one of the one or more flanges is connected to the first side wall or the second side wall.

### Claim 3 (depends on 1)

The furnace of claim 1, wherein at least one of the first rail and the second rail is integral with a panel of the first side wall or the second side wall of the heat exchanger system.

### Claim 4 (depends on 2)

The furnace of claim 2, wherein the heat exchanger system further includes a baffle connected to at least one of the one or more flanges, wherein the baffle is configured to direct airflow towards a center of the enclosure of the heat exchanger system.

### Claim 5 (depends on 1)

The furnace of claim 1, wherein the heat exchanger support is slidable along the first and second rails in a horizontal direction.
