Pressure gauge - to indicate the system pressure to be 

maintained.

6.7 Central Heating System

Boiler is designed for use in a sealed central heating system. 

Design the system to operate with flow temperatures of up to 

176°F (80° C), take pump head, expansion tank size, mean 

radiator temperature, etc. into account. 

Boiler is supplied with the following components:  Pressure 

relief valve - 30.0 psi (2.1 bar). Boiler internal pressure switch 

will shut boiler off  below 7.5 psi / 0.5 bar and above 43.5 psi 

/3.0 bar.

6.8 Domestic Hot Water Mode

Dunkirk Boiler DCCF-150 and DCBF-125 with indirect 

the pump to circulate the primary water through the DHW 

plate heat exchanger. (DCCF 150 only)

•  Combustion fan will then come on and begin to run at 

ignition speed.

•  Once the fan reaches ignition speed the control board will 

allow power to flow to the spark generator and gas valve 

creating ignition in the combustion chamber. The flame 

sensor will acknowledge the presence of the flame in the 

combustion chamber and send a signal to the control 

board.

•  Temperature sensors will send a signal to the control board 

allowing the control board to increase/ decrease the speed 

of the fan. The combustion fan will in turn modulate the 

gas rate accordingly.

•  When the domestic hot water demand ceases the burner 

will extinguish, unless there is a demand for central 

heating.

6.9 Frost Protection Mode

Frost protection mode is integrated into the appliance when 

electricity is connected to the boiler, regardless if power is "on" 

or "off".
If temperature falls below 41°F / 5° C boiler will fire on its 

minimum setting until flow temperature of 86°F / 30° C is 

reached.

6.10 Pump Protection

Pump will automatically operate for 1 minute in every 24 hours 

to prevent seizing.

•  Priority is given to the domestic hot water supply. 

Demand at tap or shower will override any central heating 

requirement.

• 

Flow of water will operate the DHW flow switch which 

requests the 3 way valve to change position. This will allow 

 WARNING

Burn, Scald Hazard! Water temperature over 125°F 

(51°C) can cause severe burns and scalding. See 

User's Manual before setting water temperature. 

Failure to follow these instructions could result in death 

or serious injury.
