This image shows the complete assembly, including the QCC1 tank connector, the adjustable regulator, and the 4-foot hose with a 3/8-inch flare swivel nut end connector. A warning is overlaid on the image stating it is for high pressure and not suitable for low-pressure appliances.
Key Features:
- Adjustable Pressure: 0-30 PSI output, controlled by a red knob.
- Compatibility: Fits QCC1/Type1 LP gas propane tanks and cylinders.
- Connection: 3/8-inch female flare connection for appliances (note: the 3/8 flare nut is 5/8 inch to accommodate the flare seat).
- Safety: Features excess flow protection that automatically shuts off gas in case of a leak or excessive flow.
- Durability: Constructed with 100% solid brass corrosion-resistant fittings.
- Applications: Suitable for propane burners, turkey fryers, heaters, smokers, and other high-pressure propane appliances. Not suitable for appliances requiring a low-pressure regulator.
2. Safety Information
WARNING: Propane gas is flammable and can cause serious injury or death if not handled properly. Always follow these safety guidelines.
- High Pressure Only: This regulator is designed for high-pressure propane appliances (0-30 PSI). Do not use with appliances that require a low-pressure regulator. Using it with a low-pressure appliance can cause damage or dangerous conditions.
- Leak Detection: Always perform a leak test with soapy water after connecting the regulator to ensure all connections are secure and leak-free.
- Excess Flow Protection: The regulator includes an excess flow protection device. If a significant leak occurs, this device will automatically restrict gas flow. If your appliance seems to be receiving low or no gas, check for leaks and ensure the tank valve is fully open.
- Ventilation: Use propane appliances only in well-ventilated areas to prevent carbon monoxide buildup.
- Storage: Store propane tanks outdoors in a well-ventilated area, away from ignition sources and direct sunlight.
- Connection Check: Before each use, inspect the hose and connections for any signs of damage, cracks, or wear. Replace immediately if damage is found.
- Proposition 65 Warning: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
3. Setup and Installation
Follow these steps to properly connect your DOZYANT propane regulator and hose to your propane tank and appliance.
- Prepare the Propane Tank: Ensure your QCC1/Type1 propane tank is upright and stable. Close the tank valve completely by turning it clockwise.

- Connect to Propane Tank:
- Ensure the regulator's red knob is set to 0 PSI (OFF position) before connecting.
- Align the QCC1/Type1 connector on the regulator with the propane tank valve.
- Thread the black plastic coupling nut onto the tank valve. Turn clockwise until hand-tight. No tools are typically needed for this connection.
- Connect to Appliance:
- Confirm your propane appliance has a female 3/8-inch flare connector. If not, appropriate adapters may be required (not included).
- Thread the 3/8-inch flare swivel nut on the hose end onto your appliance's inlet. Tighten securely with a wrench.

- Perform a Leak Test:
- Mix a solution of soapy water (50% soap, 50% water).
- Open the propane tank valve slowly.
- Apply the soapy solution to all connections (tank to regulator, regulator to hose, hose to appliance).
- If bubbles appear, there is a leak. Close the tank valve immediately, tighten connections, and re-test. Do not use the appliance if leaks persist.
4. Operating Instructions
Once the regulator and hose are securely connected and leak-tested, you can begin operation.
- Open Propane Tank Valve: Slowly open the main valve on your propane tank counter-clockwise until fully open. This allows gas to flow to the regulator.
- Adjust Pressure: The red knob on the regulator controls the output pressure from 0 to 30 PSI.
- Turn the red knob clockwise to increase pressure and gas flow.
- Turn the red knob counter-clockwise to decrease pressure and gas flow, down to 0 PSI (OFF).
Note: This regulator does not have a built-in pressure gauge. Adjust the knob gradually and observe your appliance's performance to achieve the desired flame or heat output.
- Ignite Appliance: Follow your appliance's specific instructions for ignition.
- Shut Down: When finished, first turn the red knob on the regulator counter-clockwise to the OFF (0 PSI) position. Then, close the main valve on the propane tank completely by turning it clockwise.

5. Maintenance
Regular inspection and proper care will ensure the longevity and safe operation of your DOZYANT propane regulator and hose.
- Visual Inspection: Before each use, visually inspect the entire hose for cuts, abrasions, kinks, or any signs of damage. Check the regulator body for cracks or deformation.
- Connection Integrity: Periodically check that all connections remain tight. Re-tighten if necessary, but avoid over-tightening.
- Cleaning: Clean the exterior of the regulator and hose with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: When not in use, disconnect the regulator and hose from both the tank and appliance. Store in a clean, dry, and protected area, away from direct sunlight and extreme temperatures. Avoid kinking the hose during storage.
- Replacement: If any part of the hose or regulator shows signs of damage, wear, or leakage, replace the entire assembly immediately. Do not attempt to repair damaged components.
6. Troubleshooting
If you encounter issues with your DOZYANT propane regulator, refer to the following common problems and solutions.
- Low or No Gas Flow to Appliance:
- Tank Valve Not Fully Open: Ensure the propane tank valve is fully opened. If it's only partially open, the excess flow device may activate, restricting gas flow.
- Excess Flow Device Activated: This safety feature activates if it detects a sudden, large gas flow (e.g., a leak or opening the tank valve too quickly). Close the tank valve, disconnect the regulator, wait a few minutes, then reconnect and slowly open the tank valve. Perform a leak test.
- Regulator Knob Setting: Ensure the red adjustable knob on the regulator is turned clockwise sufficiently to allow gas flow.
- Leaks: Perform a leak test with soapy water at all connections. Even small leaks can reduce pressure.
- Kinked Hose: Check the hose for any kinks or obstructions that might restrict gas flow.
- Empty Tank: Verify that the propane tank contains sufficient fuel.
- Gas Leak Detected (Smell of Gas, Hissing Sound, Bubbles during Leak Test):
- Immediate Action: Immediately close the propane tank valve.
- Tighten Connections: Check and tighten all connections (tank, regulator, appliance).
- Inspect for Damage: Look for any visible damage to the hose or regulator.
- Re-test: After tightening and inspection, perform another leak test. If the leak persists or if any component is damaged, discontinue use and replace the entire assembly.
