Installation & Service Manual
The Copper-fin - How it works...
1.Control panel cover
The control panel cover provides access to the thermostat, ignition module, and transformer.
2.Drain port (not shown)
Location from which the heat exchanger can be drained.
3.Flue outlet
The flue outlet allows the connection of the vent pipe to the unit.
4.Gas connection pipe
The gas pipe connection on this appliance should be connected to the incoming gas supply for the purpose of delivering gas to the appliance.
15.Water inlet
The water inlet is a 2" pipe connection that receives water from the system and delivers it to the heat exchanger.
16.Water outlet
The water outlet is a 2" pipe connection that supplies water to the system .
17.Burner (not shown)
The burner is a cylindrical stainless steel tube used to regulate burner flame.
5.Gas valve
The gas valve allows the proper amount of gas to pass into the burner for combustion.
6.Heat exchanger
The heat exchanger allows system water to flow through specially designed tubes for maximum heat transfer. The glass lined headers and copper finned tubing are encased in a jacket that contains the combustion process.
7.High limit sensor
Device that monitors the outlet water temperature to ensure safe operation. If the temperature exceeds its setting , it will break the control circuit, shutting the appliance down.
8.Ignition module (F9 and M9 models only)
The ignition module responds to a call for heat signal to provide burner operation .
18.Pilot (not shown)
( F9 and M9 models only)
The pilot is a spark ignition device is used to light a pilot flame which in turn is used to light the main burners.
( F1 models only)
The pilot uses a standing flame to light the main burner.
19.Sight Glass (not shown)
The sight glass provides a view of the burner surface, burner flame, and the pilot flame.
20.Temperature and pressure gauge (CB models only)
The temperature and pressure gauge monitors the outlet temperature of the boiler as well as the system water pressure.
21.Pump (shipped with CW models only)
The pump ensures adequate flow to operate the unit.
9. Junction box
The junction box contains the connection points for the line | 22. Pump relay | |
The pump relay energizes the pump on a call for heat. | ||

10.Relief valve
The relief valve is a safety device that ensures the maximum pressure of the appliance is not exceeded. Water heaters are supplied with a temperature and pressure relief valve.
23.Temperature sensor
This sensor monitors inlet water temperature. If selected as the controlling sensor, the appliance will maintain the setpoint at this sensor.
11.Terminal strip
The boiler is equipped with a terminal strip on the left side of the control panel to allow easy connection to contact points on the unit.
12.Thermostat
The thermostat monitors the water temperature via a temperature sensor and will initiate a call for heat when the water temperature drops below the setpoint plus the differential on the thermostat.
13.Temperature gauge (CW models only)
The temperature gauge monitors the inlet temperature of the water heater as well as the outlet temperature.
14.Transformer
The transformer reduces 120 VAC supply voltage to 24 VAC for the control circuit.
