Energy Safe Victoria advises owners of caravans, motor homes or camper trailers that there is a potential safety risk while operating these appliances on LP Gas.

What are the hazards?

Under certain conditions, the water heaters can generate elevated levels of carbon monoxide (CO), which, in some instances, 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.

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. This can be done by checking the appliance data plates found under the front cover plate of the hot water heater (see instructions on the following page).

If you are unable to do this, your 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. It is safe to continue operating your Suburban water heater if it can operate from a 12 or 240 volt supply. Further Recall/Safety notices will be provided as to what actions are required to rectify the safety issues.

How to check your appliance’s model and serial number

1. Remove the hot water heater cover plate. Make sure to let it cool first if the appliance has recently been used.
