Water Heater Bypass System - Holiday Navigator 2003 Owner's Manual

The next portion of the operation is controlled by the direct spark ignition
(DSI) system, as power is applied to the DSI board. The system will do the
following:
1. The board has a timing circuit, which allows 6 to 9 seconds for ignition to
occur.
2. Initially the board supplies current to the gas valve. At the same time, it
produces a high-voltage current supply to the electrode to produce a spark
at the burner.
3. The board will also confirm the presence of a flame.
If the flame is not sensed within six to nine seconds, the module board will
go into lock out. Flame sensing is through the spark wire.
The Thermostat-Limit controls the power to the module board. At 130° F,
the thermostat will open shutting off the burner. If the thermostat fails, the
safety High Temperature limit switch will open, and requires manual resetting.
The bypass valve is located on the back of the water heater.
Turning the valve to BYPASS diverts water away from the
water heater. Place the valve in the BYPASS position when
winterizing. Bypassing the water heater prevents water or
antifreeze from entering the water heater. For normal operation,
turn valve so that handle points to NORMAL FLOW.
