Spill Switch w/ Manual Reset, 240°F for CG, CGA, CGx Boilers Weil McLain spill switch with manual reset, 240°F, for boiler models: CGA CGx CG Combustion gas or flue gas spill switches are usually installed at the edge of the gas fired appliance draft hood. Some appliances may also have a spill switch installed at the gas burner opening itself. What goes wrong with flue gas spillage detection switches Missing flue gas spill switches: we've seen these switches removed from modern water heaters, gas boilers, or gas furnaces when they were originally installed. If you see holes drilled into the edge of a draft hood or other marks indicating that a device has been removed, or if you see the devices themselves lying loose, perhaps on or near the equipment, an expert service technician should examine the heater promptly as it may be unsafe. Improperly-installed flue gas spill switch: if the spillage switch sensing area is in contact with metal surfaces such as the flue or the draft hood, the heat of that metal may cause the switch to malfunction. The flue spillage switch sensor should be mounted so that it monitors the temperature of gases spilling out of the heating appliance such as at the draft hood, vent, or chimney or on some systems near the gas burners. Misplaced flue spillage switches: similarly to the improperly installed spill switches whose temperature sensor should not touch metal surfaces of the heating system, the spill switch needs to be installed in the proper location so that if a chimney blockage or some other operating problem causes combustion gases to spill out of the appliance into the building, the flow of flue gases, while still warm, will pass over the switch sensor. There may be other flue spillage switches which sense carbon monoxide (CO) or other gases directly and without depending on the gas temperature. Older heaters with no flue spill switch: On older heating systems these safety switches may not be installed at all. ....read more

IQ Boiler Control for ES2_B Series 30_B and

December 15th, 2018

Burnham
$196.28
IQ Boiler Control The heart of IQ Control System is the Intelligent Hydronic Control. The control replaces the traditional separate ignition control, primary boiler aquastat, as well as the fan and circulator relays. The control stores two boiler supply temperature setpoints in its memory; one setpoint is for the High Limit Setting and the second is for the Operating Setpoint. When the optional Outdoor Air Reset Card is installed in the IQ Option Panel, the Operating Setpoint temperature is automatically adjusted according to the outdoor temperature. By better matching boiler heat supply to actual home heat demand, room air temperatures are more closely maintained. Also, when there is a domestic hot water (DWH) heat request, the Operating Setpoint temperature is automatically adjusted to a DHW Setpoint to satisfy the DWH heating requirements. When the Outdoor Air Reset Card is not installed the Operating Setpoint equals High Limit Setting. Atmospheric Draft is used on Boiler ES2_B, Series 30_B and, 2012 Series 2 **Image may not depict actual product.** ....read more
