3. Ducting: Connect all necessary air ducts for supply and return air. Ensure ducts are properly sealed to prevent air leaks.
4. Gas Connection: Connect the propane gas line to the furnace. Use appropriate fittings and ensure all connections are leak-tested using a non-corrosive leak detection solution.
5. Electrical Wiring: Connect the 12-volt DC power supply and thermostat wiring according to the wiring diagram provided with the unit. Ensure correct polarity and secure connections.
6. Ventilation: Verify that the exhaust and intake vents are clear and unobstructed to ensure proper combustion and prevent carbon monoxide buildup.

Refer to the detailed installation instructions provided with your specific unit for precise steps and diagrams. Adherence to all local and national codes is mandatory.

5. Operating Instructions

Once the furnace is properly installed and all connections are verified, follow these steps to operate your Suburban SF-30 Dynatrail furnace:

1. Power On: Ensure the 12-volt DC power supply to the furnace is turned on.
2. Gas Supply: Open the main propane gas supply valve to your RV.
3. Thermostat Setting: Set your RV's thermostat to the desired temperature. Ensure the thermostat is set to 'HEAT' mode.
4. Ignition Cycle: The furnace will typically initiate an ignition cycle. You should hear the blower fan start, followed by the igniter attempting to light the burner. This process may take a few moments.
5. Heat Output: Once ignited, the furnace will begin to produce warm air. The blower will continue to run until the thermostat's set temperature is reached.
6. Shut Down: To turn off the furnace, lower the thermostat setting below the ambient temperature or switch the thermostat to 'OFF' mode. For extended storage, turn off the main propane supply and the 12-volt power to the furnace.

If the furnace fails to ignite after several attempts, refer to the Troubleshooting section.

• Annual Inspection: Have the furnace inspected annually by a qualified technician. This includes checking the heat exchanger, burner, ignition system, and gas connections.
• Clean Air Intake/Exhaust: Periodically check and clean the exterior air intake and exhaust vents to ensure they are free from obstructions (e.g., leaves, debris, insect nests).
• Blower Motor: Listen for unusual noises from the blower motor. If present, consult a technician.
• Ductwork: Inspect all ductwork for leaks or damage. Repair as necessary to maintain heating efficiency.
