Question:
I have a food trailer can I put the propane tankless on demand water heater under The sink cabinet. I can add a Small fan for air flow. Or would It be better to use A tank that vents out?

Hey Deb,
The Furrion RV Tankless Water Heater # FR93FR would need to vent out to the outside of the trailer. The rear of the unit can sit in a cabinet but you would not be able to have it vent inside the trailer. The Excel RV Tankless Water Heater # EX93FR wouldn't have as great of an output but would be able to be installed in a cabinet without having to be vented outside. The # EX93FR requires 3" of clearance on the sides and 8" of clearance above to allow for proper airflow. I would still add a vent or something to keep air flowing through that cabinet to prevent the oxygen sensor in the # EX93FR from shutting itself off.
