BP-VALVE (By-pass Valve): Enabled/Disabled
By-pass Valve Description
The purpose of the automatic BPVALVE (bypass valve) feature is to by-pass the flow of water from the heater
inlet to the heater outlet when the heater is not firing. There is a minimal amount of water flow through the
heater when the heater is not firing, and a maximum water flow through the heater when the heater is firing.
For more information about Manual By-Pass and Automatic By-Pass valves, see page 12-13.
By-Pass Enabled
When the BYPASS VALVE feature is enabled and there is a call for heat, the by-pass valve closes to allow
water to flow through the heater. It takes 30 seconds for the bypass valve to rotate to the closed position. This allows
the valve to complete rotation so there is sufficient water flow and pressure to prevent the water pressure switch from
trigging an error. When the call for heat ends, the water flow continues through the heat exchanger for a cool down
period of one minute. After the cool down period, the by-pass valve will rotate so that water no longer flows through
the heater.
By-Pass Disabled
When the BYPASS VALVE feature is disabled, there is no automatic switching of the by-pass valve when the heater
starts a heating cycle. The valve stays in the position and water always flows through the heater.
