In this guide: Understand RV propane cylinders, regulators, appliances and safe operation.
Safety first: Never test for leaks with a flame, modify regulators or repair gas piping yourself.

How this RV system works

An RV propane installation commonly includes a certified cylinder or permanently mounted tank, shutoff valve, regulator, distribution piping and individual appliances. Systems and shutoffs differ between travel trailers and motorhomes.

Before you begin

Find the model number and instructions for the exact appliance fitted to your RV. A travel trailer, fifth-wheel and motorhome may have very different controls, ventilation and power supplies. Check campground rules before running generators or fuel-burning equipment.

Step-by-step owner checks

  1. Locate the cylinder or tank shutoff, regulator, appliance controls and propane detector using your owner manuals.
  2. Before travel, check that cylinders are secured, protected from impact and carried in the orientation required by their design.
  3. Inspect visible hoses and regulator covers for cracking, corrosion, rubbing or damage without loosening any fittings.
  4. Follow each appliance manufacturer’s lighting and shutdown instructions; keep exterior combustion vents clear.
  5. If any odour, alarm or damage appears, stop use and contact a qualified propane technician.

Canadian weather and regulations

Canadian propane installations and service are subject to provincial or territorial requirements and applicable adopted codes. Ask your provincial safety authority about qualified service and inspection.

Propane equipment installation, inspection and repair requirements can vary by province and territory. Check with the appropriate local safety authority and use a properly qualified service provider. Winter campsite availability, electrical hookups and fuel access also vary.

Preventive maintenance

Have a qualified professional inspect the system at the interval recommended by the RV and appliance manufacturers.

Record inspection dates, fault codes and any repairs in your RV maintenance log. Keep combustion-air openings, appliance exhausts and detectors unobstructed, and check all relevant alarm expiry dates.

Reliable Canadian and safety references

These are general starting points, not a substitute for your provincial gas-safety authority or manufacturer service documentation.

Propane in Canada

Propane is widely available at fuel stations and dealers, but cylinders must be in date and in good condition to be filled. Qualified technicians should handle installation and repairs.

Standards and service

  • RV gas systems are built to the CSA Z240 series of standards.
  • Propane installations and repairs belong with qualified technicians.
  • Check hoses, regulators and fittings for wear every season.
  • Test for leaks with an approved method, never with a flame.
  • Know where the shut-off valves are.
How often should the system be inspected?

Follow your manufacturer’s schedule and have it checked after any impact or unusual smell.
