Water Heater Sensors (Inlet – Outlet – Flue - Outdoor) - Sensors
provide highly accurate temperature monitoring to assure accurate
system control. These sensor inputs can be monitored through the
water heater control system and display.
Pressure Gauge – Allows the user to monitor system pressure.
System Safeties – The water heater is provided with many safety
features to ensure reliable and safe operation. Each safety is
connected to the water heater control. The water heater will alert the
user if an unsafe condition occurs and needs to be addressed. The
following are provided safeties: Flue Pressure Switch (monitors ue
pressure), Burner High Limit (monitors burner plate temperature),
High Limit Water Switch (monitors water heater water temperature),
Low Water Sensor (monitors water level in the heat exchanger),
optic ame sensor (monitors ame quality), Flue Sensor (monitors
ue temperature), Condensate Pressure Switch (monitors pressure to
ensure condensation does not back up into water heater).
Manual Air Vent – Each water heater is equipped with an air vent to
discharge air from the system during start–up.
Intake and Exhaust Adapters – The water heater is equipped with
adapters to ease connection to the vent system. The adapters are
provided with clamps and seals to secure eld supplied piping, and
test ports to ease monitoring of the combustion system. Each water
heater is supplied with a 6 inch piece of CPVC that must be connected
into the exhaust vent adapter.
Gas Connection – The water heater is equipped with a ¾” gas
connection to connect the incoming gas supply.
