Installation

Unpack and inspect all components. Ensure proper ventilation and clearances.

Mount furnace: Secure to RV frame using provided brackets and hardware.
Connect gas line: Use approved propane fittings and check for leaks.
Wire electrical: Connect to 12V DC power source with proper fuse protection.
Install thermostat: Mount in living area and connect control wires.
Verify exhaust: Ensure vent pipe is clear and properly routed outside.

WARNING! Gas appliances require professional installation. Ensure all connections are leak-free and secure.

First-Time Setup

Power on furnace; follow startup sequence.

Check gas supply: Ensure propane tank is open and has adequate pressure.
Set thermostat: Adjust to desired temperature setting.
Test ignition: Listen for spark and burner ignition sequence.
Verify airflow: Check that blower operates and heat distributes properly.
Calibration: Allow furnace to complete initial heating cycle.

CAUTION! Keep flammable materials away from furnace and vents during operation.

Connecting to Power Source

12V DC power connection with proper grounding.

Turn off all power sources before connecting.
Connect positive and negative wires to appropriate terminals.
Install inline fuse (5-10 amp) in positive wire.
Verify proper voltage at furnace connections.
Test operation with thermostat control.

Tip: Use marine-grade wire and connectors for durability in RV environment.

Operating the Furnace

Supports automatic heating cycles with safety monitoring.

Startup: Set thermostat above current temperature.
Ignition sequence: Blower starts, spark ignition activates, gas valve opens.
Heating: Burner ignites, heat exchanger warms, blower distributes warm air.
Shutdown: Thermostat satisfied, gas valve closes, blower continues for cool-down.
Mode selection: Choose between auto fan and continuous fan operation.

WARNING! Never operate furnace with blocked vents or restricted airflow.

Maintenance Procedures

Regular maintenance ensures optimal performance and safety.

Monthly: Check and clean air intake and exhaust vents.
Seasonal: Inspect burner assembly and clean if necessary.
Annual: Professional inspection of heat exchanger and gas components.
As needed: Replace air filter and check electrical connections.

Care & Cleaning

Turn off power and gas supply before cleaning. Use soft brush and compressed air for vents.

CAUTION! Do not use water or liquid cleaners on electrical components. Keep vents clear of debris.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Furnace won't start	Power/gas supply	Check 12V power, verify gas valve open, check thermostat setting.
No heat output	Ignition failure	Listen for spark; check gas pressure; clean burner assembly.
Blower runs but no heat	Gas valve/ignition	Verify gas supply; check ignition system; inspect flame sensor.
Furnace cycles on/off frequently	Airflow/overheating	Clean air filter; check vents for obstruction; verify proper clearance.
Error code displayed	System fault	Refer to error code chart in manual; reset power; contact service.

Reset: Turn thermostat off, wait 5 minutes, then restart.
