Abstract
A blown air heating system has a housing having an upstream air inlet and a downstream air outlet and a forced-air device configured to draw air into the housing via the air inlet and force the air out of the housing via the air outlet, wherein the air follows an airflow path from the air inlet to the air outlet. A gas burner is configured to heat the air as it passes through the housing. A gas valve is configured to provide a fuel gas to the gas burner, and the gas valve is located between the air inlet and the air outlet and in the airflow path. A baffle is in the airflow path, and the baffle is configured to divert the flow of air away from at least part of the gas valve.
Claims20
A blown air heating system comprising:
- a housing having an upstream air inlet and a downstream air outlet;
- a forced-air device configured to draw air into the housing via the air inlet and force the air out of the housing via the air outlet, wherein the air follows an airflow path from the air inlet to the air outlet;
- a gas burner configured to heat the air as it passes through the housing;
- a gas valve configured to provide a fuel gas to the gas burner, wherein the gas valve is located between the air inlet and the air outlet and in the airflow path;
- and
- a baffle in the airflow path, the baffle being configured to divert the flow of air away from at least part of the gas valve.
A blown air heating system comprising:
- a housing having an upstream air inlet and a downstream air outlet, the housing having a longitudinal axis that extends through the air inlet and the air outlet;
- a forced-air device having a plurality of blades and being configured to draw air into the housing via the air inlet and force the air out of the housing via the air outlet, wherein the air follows an airflow path from the air inlet to the air outlet;
- a gas burner configured to heat the air as it passes through the housing;
- a gas valve configured to provide a fuel gas to the gas burner, wherein the gas valve is located within a projection along the longitudinal axis of a circle circumscribing the plurality of blades of the forced-air device;
- and
- a baffle in the airflow path, the baffle being configured to divert the flow of air away from at least part of the gas valve.
A blown air heating system comprising:
- a housing having an upstream air inlet and a downstream air outlet, the housing having a longitudinal axis that extends through the air inlet and the air outlet;
- a forced-air device configured to draw air into the housing via the air inlet and force the air out of the housing via the air outlet, wherein the air follows an airflow path from the air inlet to the air outlet;
- a motor powering the forced-air device, wherein an output shaft of the motor is coaxial with the longitudinal axis of the housing;
- a gas burner aligned along the longitudinal axis of the housing and configured to heat the air as it passes through the housing;
- a gas valve configured to provide a fuel gas to the gas burner, wherein the gas valve is located directly adjacent the motor;
- and
- a baffle in the airflow path, the baffle being configured to divert the flow of air away from at least part of the gas valve.
