Winterizing
If you will not be using your heater for a long
period of time or if the temperatures will drop
below 5º F (-15º C) with the wind chill factor,
turn off your heater and drain the unit of water.
This will keep your unit from freezing and being
damaged. Follow these instructions carefully:
1. Turn off the power supply to the Flash
Water Heater.
2. Turn off the manual gas control valve
located outside your heater.
3. Turn off the manual water shut off valve
located on the water supply line.
4. Open all hot water taps in the house.
(Bathroom, kitchen, laundry room, etc.).
When the water flow has ceased, close all
hot water taps.
5. Have a bucket or pan to catch the water
from the units drain plugs. Remove the
drain plugs to drain all the water out of the
unit.
6. Wait a few minutes to ensure all water
have drained from unit.
7. At this time please check the water filter
located inside the cold inlet. With a tiny
brush, clean the water filter of any calcium
or debris which may have accumulated
over time and reinsert the filter back into
the cold water inlet.
8.
Securely screw the drain plugs back into
place.
Now when you want to use your heater
again follow these steps:
Make sure all hot water taps are closed and
the drain plugs are securely attached.
1. Purge the water line of debris.
2. Turn on the manual water control valve
located on the water supply line.

flows to the taps. Then close hot water
taps.

5. Turn on the power supply to the MOBIUS
Water Heater.
CAUTION:
The pipe heaters are located on
the MOBIUS Water Heater only. Any hot or
cold water pipes located outside of the unit will
not be protected. Properly protect and insulate
these pipes from freezing.
