Winterising
When using the Water Heater in winter, ensure the flue is not blocked by snow or fallen leaves
etc. When not in use the Water Heater must be fully drained. This is particularly important during
the winter months as a precaution against freezing. To drain, switch off the water pump at either
the pump switch or main switch. Open all the hot water taps in the vehicle and operate the drain
valve fitted in the system. The drain valve must be left in the “open” position to ensure all the
water drains out.
