LP Gas Furnace /Heater - The Atwood Excalibur Furnaces with electronic ignition are Efficient and Quiet

The RV furnaces - Atwood (Hydro Flame) Excalibur 8500 IV series have all the great features of the Excalibur XT furnaces, but does not include a thermostat. They have been redesigned to be more efficient and quieter with a new burner and blower assembly. The new design has eliminated the obstruction and minimized the turbulence in the blower housing. This decreases overall noise with an increase in airflow.

Ease of Installation

The compact size, low profile, gas heaters are of lightweight construction.  They also offer a vertical installation option that enhances space utilization possibilities. This provides placement flexibility. A flexible adapter kit makes bottom discharge installation easy for both new and replacement applications.

Serviceability of Excalibur LP Gas Furnaces

Due to the unique design features and Exterior Access Door of the 8500IV, all controls and crucial components are easily accessible from outside the vehicle, which eliminates the need to remove the furnace. In addition, there is no carbon build-up maintenance required. (Note: Access door and Thermostat are not included.)

Unique Vent Design

The 8500IV incorporates a unique outside vent design integral with the access door, which eliminates the need for a variety of vent kits. The cutout size required for  Atwood Excalibur is 7 1/2" H x 16 1/2" W.
