What are the hazards

Under certain conditions, the water heaters can generate elevated levels of Carbon Monoxide (CO). In some instances CO may spill into the caravan, motor home or camper trailer. Carbon monoxide is a colourless, odourless gas that can adversely affect the health when inhaled. Carbon monoxide can be lethal in large concentrations.  For more information on carbon monoxide, visit: What is carbon monoxide

What to do

Immediately stop using the appliance. Identify whether your hot water heater is one of the affected models and if the serial number falls within the ranges listed above. Do this by checking the appliance data plates found under the front cover plate of the hot water heater.  Download a copy of the Safety Warning Notice for caravan owners, agents and manufacturers (PDF, 331.2 KB) for further information on how to check appliance models and serial numbers.  If you are unable to do this, your gas-fitter or caravan service agent should be able to assist.

If the water heater model is confirmed to be one of models listed above, then it must NOT be used until rectified by an authorised Suburban agent or dealership. The gas isolation valve to this appliance must be turned off until the appliance and installation has been rectified.

The safety issues only apply while the appliance is operating on gas. If your Suburban water heater can operate from a 12 or 240 volt electrical supply as well as from LP Gas, it is safe to continue operating the appliance from the 12 or 240 volts only.
