- Turn on the gas supply slowly.
- Mix a solution of soapy water (50% soap, 50% water).
- Apply the soapy solution to all connections (hose to supply, hose to appliance).
- Observe for bubbles. The presence of bubbles indicates a gas leak.
- If a leak is detected, immediately turn off the gas supply, tighten the connection, and re-test. If the leak persists, do not use the hose and contact a qualified technician.
5. Operating Instructions
Once the hose is securely installed and leak-tested:
- Ensure the appliance's control knobs are in the OFF position.
- Slowly open the main gas supply valve.
- Follow your appliance's specific instructions for lighting and operation.
- When finished, turn off the gas supply at the source first, then turn off the appliance's control knobs.
- If disconnecting the hose, ensure the gas supply is off and the appliance is cool. To disconnect the quick-connect, pull back the collar on the female receiver and pull the male fitting out. Replace dust caps on fittings.
6. Maintenance
- Regular Inspection: Before each use, visually inspect the entire length of the hose for any signs of wear, damage, cuts, kinks, or excessive bending. Check fittings for corrosion or damage.
- Cleaning: Clean the hose and fittings with a mild soap and water solution. Rinse thoroughly and dry completely before storage or use. Do not use abrasive cleaners or solvents.
- Storage: When not in use, disconnect the hose from both the gas supply and the appliance. Replace the protective dust caps on the quick-connect fittings. Store the hose in a clean, dry, and protected area, away from direct sunlight, extreme temperatures, and corrosive materials. Avoid kinking the hose during storage.
- Replacement: If any damage is found during inspection, or if the hose shows signs of significant wear, replace it immediately with a new, CSA-certified hose.


7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Gas leak detected (bubbles during leak test) | Loose connection, damaged fitting, or damaged hose. | Immediately turn off gas supply. Tighten all connections. Re-test. If leak persists or hose is damaged, replace the hose. Do not use a leaking hose. |
| No gas flow to appliance | Gas supply valve closed, quick-connect not fully engaged, kinked hose, or appliance issue. | Ensure gas supply valve is fully open. Check quick-connect for full engagement. Inspect hose for kinks. Verify appliance is functioning correctly with another gas source if possible. |
| Difficulty connecting/disconnecting quick-connect | Dust/debris in fitting, collar not fully retracted, or damaged fitting. | Ensure fittings are clean. Pull back the collar on the female receiver completely. If fitting is damaged, replace the hose. |
