  If you smell gas, immediately close the main gas valve. Do not operate any switches or use any open flames. Ventilate the boiler room and immediately contact your installation engineer or local gas company, as this could indicate a gas leak.

Why is there insufficient or no hot water from my DORCHESTER DR-FC 120 Water Heater?

  There could be several reasons why you're not getting enough hot water. First, ensure the water heater is turned on. Check that the isolator is on, there's power to the isolator, and the controller's ON/OFF switch is in the 'I' position. Also, verify power to the electrical connector block and that the voltage is 230 VAC (-15%, +10%). Another reason may be that the hot water supply is used up, in that case reduce hot water consumption and give the water heater time to heat up. The controller may be in the OFF position, so switch the controller to the ON position. Lastly, the temperature might be set too low, so set the temperature to a higher setting.
