Tubular Indoor Duct Furnace

Product Information


The BTD Series duct furnace is the latest addition to the Beacon Morris tubular product line. Designed for use with existing systems for any ducted air application. Beacon Morris indoor tubular duct furnaces are available in 7 sizes (100 – 400 MBH). Beacon Morris products are proudly manufactured in the USA.

Standard energy saving features like the direct spark ignition and power venting reduce standby losses and offer improved seasonal efficiencies. The BTD Series is certified by ETL as providing 82% thermal (combustion) efficiency.


The Beacon Morris tubular heat exchanger has been designed to provide maximum and uniform heat transfer. The low pressure drop associated with this design enables heated air to be evenly distributed to the conditioned space. This curved, non-welded serpentine design experiences less thermally induced stress making it highly durable for significantly longer service life. All standard Beacon Morris tubular heat exchangers are constructed of heavy duty 20-gauge aluminized steel with an optional 409 stainless steel heat exchanger available for applications in mildly corrosive environments.


Beacon Morris BTD units utilize a direct spark pilotless ignition of the burner, providing fast heat delivery. This highly reliable and efficient ignition system incorporates an integrated electronic control board to regulate the system sequence of operation, including an externally mounted LED indicator for simple troubleshooting.


The Beacon Morris BTD Series is ETL certified in accordance with category III venting requirements. This certification allows units to be vented both vertically and horizontally using either single wall or double wall venting materials. This venting flexibility of the BTD duct furnace makes installation easier and more cost effective by allowing the installer to utilize existing venting components. The BTD duct furnace can be field converted to separated combustion using the “Air Inlet Kit” or the “Combustion Air Inlet Kit”. This is recommended for units to be installed in dusty, dirty or mildly corrosive environments or where high humidity or slightly negative pressures exist. All critical components including the burners, direct spark ignition, and controls are fully enclosed within the unit and protected from the elements ensuring clean and efficient combustion.


Designed with the service person in mind, every component of the Beacon Morris BTD Series is easily accessible. Ignition and fan controls are located in one centrally located control panel. The access panel provides control isolation as well as a pleasing exterior appearance.
