KINGRVER 35,000 BTU Powerful RV Furnace, HF35-E Heater, LP Gas

The right furnace size depends on your RV’s insulation, layout, and expected outdoor temperatures. Start with your existing furnace’s BTU rating and your RV manufacturer’s recommendations. If you’re considering a different capacity, consult a qualified RV technician before ordering.

Compatibility depends on more than BTU rating. Check the installation dimensions, venting arrangement, duct connections, propane connection, and electrical requirements. For help checking compatibility, contact KINGRVER Support with your current furnace model, a photo of its rating label, and your installation measurements.

The HF35-E uses propane to produce heat and requires 12V DC power to operate the blower, ignition, and controls. Both supplies are required—it cannot heat using electricity alone.

The furnace measures 17.7″ W × 7.8″ H × 20.1″ D. Allow additional space for the required ventilation, ductwork, exhaust routing, and service access specified in the installation manual.

Yes. The HF35-E supports both horizontal and vertical mounting. Follow the installation manual for approved positioning, clearances, ventilation, and connection requirements.

The HF35-E uses 4-inch round duct outlets. Check your RV's existing duct layout and airflow requirements before installation.

No. An insect screen is not included in the package. Any additional vent accessories must be suitable for the furnace and must not restrict required combustion airflow or exhaust flow.

The HF35-E features thermostat-based temperature control. Set your desired temperature using the compatible thermostat and follow the operating instructions for normal heating cycles.

The HF35-E is rated at 50 dB or less under the manufacturer's stated conditions. Actual sound levels may vary depending on the installation, ductwork, and RV interior.

Yes, provided your RV has an adequate propane supply and a suitable 12V DC power source. The furnace still requires electrical power for operation, even when propane is available.

Regularly inspect accessible vents and duct openings for dust, debris, or blockages. Have a qualified RV technician inspect the propane system, exhaust connections, and furnace components as recommended in the user manual.

Check that the thermostat is calling for heat, the 12V DC power supply is available, and the propane supply is turned on. If the furnace still fails to operate, follow the manual's troubleshooting instructions or contact KINGRVER Support. Do not bypass safety controls.

Stop using the furnace immediately. Avoid flames, sparks, and electrical switches. Leave the area, shut off the propane supply if safe, and seek help from a qualified professional or emergency service before operating the furnace again.
