Introduction
This manual provides essential instructions for the safe and effective use of your Flame King 72-inch Propane Thermo Plastic Hose Assembly. This hose is designed to connect propane-powered appliances to the low-pressure propane system of your RV, travel trailer, or camper. Please read this manual thoroughly before installation and operation to ensure proper function and safety.
Important Safety Guidelines
Propane gas is flammable and can be dangerous if not handled correctly. Always follow these safety precautions:
- Outdoor Use Only: This hose and connected appliances are for outdoor use only. Never use propane appliances indoors or in enclosed spaces.
- Leak Checks: Always perform a leak test with a soapy water solution after any connection is made or changed. Never use an open flame to check for leaks.
- Proper Connections: Ensure all connections are tight and secure. Do not overtighten.
- Inspect Regularly: Before each use, inspect the hose for cuts, abrasions, bulges, kinks, or any signs of damage. Do not use a damaged hose.
- Keep Clear: Keep the hose away from hot surfaces, sharp edges, and moving parts.
- Ventilation: Ensure adequate ventilation when using propane appliances.
- Emergency: In case of a gas leak, immediately shut off the propane supply, ventilate the area, and do not operate any electrical switches or ignition sources.
Product Components
The Flame King 72-inch Propane Hose Assembly consists of a durable thermoplastic hose with two distinct connectors:
- 1/4" Male Quick Disconnect Plug (Model 250): This end connects to the female quick disconnect port on your RV's propane system. It features a protective cap.
- 3/8" Female Flare Swivel: This end connects to the 3/8" male flare fitting on your propane appliance.

Setup Instructions
Follow these steps to properly connect your propane hose assembly:
- Preparation: Ensure the propane supply valve on your RV and the control knob on your appliance are in the OFF position.
- Connect to Appliance: Attach the 3/8" Female Flare Swivel end of the hose to the 3/8" Male Flare fitting on your propane appliance. Hand-tighten first, then use a wrench to secure it firmly. Do not overtighten.
- Connect to RV: Insert the 1/4" Male Quick Disconnect Plug into the female quick disconnect port on your RV's propane system. Push firmly until you hear or feel a click, indicating a secure connection.
- Leak Test: With all connections made, slowly open the propane supply valve on your RV. Apply a soapy water solution (half liquid soap, half water) to all connections. If bubbles appear, a leak is present. Immediately close the propane supply, tighten connections, and re-test. If leaks persist, do not use the hose and seek professional assistance.
Operation
Once the hose is securely connected and leak-tested:
- Open Propane Supply: Slowly open the propane supply valve on your RV.
- Operate Appliance: Follow the specific operating instructions for your propane appliance to light and use it.
- Shut Down: After use, turn off the appliance's control knob first, then close the propane supply valve on your RV.
- Disconnect: To disconnect, ensure the propane supply is off and the appliance is cool. Pull back the collar on the RV's female quick disconnect port and pull out the male plug. Replace the protective cap on the male quick disconnect plug.
Maintenance and Care
Regular inspection and proper care will extend the life of your propane hose assembly:
- Visual Inspection: Before each use, visually inspect the entire length of the hose for any signs of wear, damage, or deterioration. Check for cracks, cuts, bulges, or kinks.
- Connector Inspection: Examine the brass connectors for corrosion, damage, or debris. Ensure the quick disconnect plug's protective cap is used when the hose is not connected to prevent dirt and moisture ingress.
- Cleaning: Clean the hose and connectors with mild soap and water if necessary. Rinse thoroughly and allow to dry completely before storage or use.
- Storage: Store the hose in a cool, dry, and well-ventilated area, away from direct sunlight, extreme temperatures, and corrosive chemicals. Avoid kinking the hose during storage.

Troubleshooting
If you encounter issues with your propane hose assembly, refer to the following common problems and solutions:
- No Gas Flow to Appliance:
- Ensure the RV's propane tank has sufficient fuel.
- Verify the RV's propane supply valve is fully open.
- Check that the quick disconnect plug is fully engaged and locked into the RV's port.
- Inspect the hose for severe kinks or blockages.
- Gas Leak Detected (Bubbles during leak test):
- Immediately shut off the propane supply.
- Tighten all connections (appliance and RV quick connect).
- Re-perform the leak test. If bubbles still appear, the hose or a connection may be faulty. Do not use and replace components as necessary.
- Difficulty Connecting/Disconnecting:
- Ensure fittings are clean and free of dirt or debris.
- Do not force connections. Check for proper alignment.
- For quick disconnect, ensure the collar is fully pulled back before inserting/removing the plug.
