Technical Specifications

Frequently Asked Questions

What size RV is the DFMDH35111 35K BTU furnace suitable for?

This 35,000 BTU furnace is designed for larger RVs, typically 35-45 feet in length, including spacious motorhomes, fifth wheels, and travel trailers. It provides sufficient heating capacity for extended cold-weather camping and full-time RV living in winter conditions.

What makes the Soft Start technology beneficial?

Soft Start technology gradually ramps up the blower motor instead of starting at full speed immediately. This reduces startup noise significantly, extends motor life by reducing wear, and draws less initial power from your RV's electrical system—important when running on battery or generator power.

How does the Hall Effect Sensor improve reliability over older ignition systems?

The automotive-grade Hall Effect Sensor provides more accurate flame detection and monitoring compared to traditional thermocouples. It ensures reliable ignition in various conditions, responds faster to flame status changes, and requires less maintenance over the furnace's lifespan.

Does this furnace come with everything needed for installation?

Yes, the DFMDH35111 includes an access door and thermostat. However, you may need additional ducting, mounting hardware, or LP gas fittings depending on your specific RV configuration and whether you're replacing an existing furnace or installing in a new location.
