The gas pressure switch is mounted on the casing of the water heater adjacent to the heater's thermostat/gas control valve. It should be mounted close enough so that the supplied 1/4" tubing will reach from the gas pressure switch fitting to the thermostat/gas valve pressure tap port. The two provided screws are self-tapping and drilling. The screws do not require the use of a drill and their 1/2" length assures that the inner tank will not be penetrated

Heats a 2 ½ car garage. Turns unheated space into a workshop, exercise room or laundry room.

Gauge dial: 2" diameter. ASSE 1017 Listed. Lead Plumbing Law Compliance: (0.25% Max. weighted average lead content). Lead Plumbing Law Certified by IAPMO R&T.

Adjustable, anti-scald thermostatic mixing valve. The thermostatic mixer is used in systems producing domestic hot water or in radiant panel heating systems. Its function is to maintain the temperature of the mixed water supplied to the user constant at the set value when there are variations in the supply conditions of the incoming hot and cold water. The valve has been specifically certified to ASSE 1017.

Grundfos UPS15-35SFC is a 1/6HP, 3-Speed Circulator Pump with stainless steel housing, suitable for a wide range of open loop and closed loop applications, including radiant heating, hydronic heating, solar, hot water recirculation, chilled water cooling and many others. 3 speeds of the Grundfos UPS15-35SFC model allow to adjust pump's parameters to match system requirements and achieve optimal performance.

Wet rotor circulation pump, with flanged connection. (Flange perpendicular to shaft). Cast iron body for hot-water heating systems of all kinds, industrial circulation systems, cold-water systems and air-conditioning systems.

These differential pressure controls are for use as operating controls and/or indicating system functions through display lights or panels. They measure the difference in pressure exerted upon its two sensing elements. The controls are available for applications sensing air, oil or liquid. Typical applications are proof of flow across a chiller or water cooled condenser, proof of flow in a heating or cooling coil and lube oil pressure sensing on refrigeration compressors. On a proof of flow application the control measures pressure drop across two different points in either a closed water circulating system or a city water to supply system.

On a proof of flow application in a water chiller system the control activates a light or signal to indicate a loss of water.The control may also be applied as a lube oil pressure sensing control on refrigeration compressors. They may be used in combination with P28 and/or P45 oil pressure cutout controls on two compressor, single motor units to reduce the oil system cost. Special low pressure models are available for variable speed and screw compressor oil pressure applications.

Single and double pole models are available with contacts that open on a pressure differential increase or close on a pressure differential increase. Also available are models with single-pole, double-throw enclosed contacts or with main and separate reverse-acting auxiliary contacts. Controls with lockout feature require manual reset to reclose circuit after lockout. The ?trip-free? reset will not permit restart until reset button is pushed and released. The operation point of the control is readily adjusted by rotating the adjusting disk. The control set points are easily read on a calibrated scale.

Heating appliances are designed to operate with a consistent draft. Chimney configurations, mechanical draft fans and weather can cause draft fluctuations. These fluctuations result in inefficient combustion and more frequent service calls. Draft controls regulate the airflow through a chimney or vent. By diluting the chimney/vent draft with varying amounts of room air they maintain the draft at a heater's flue outlet within a consistent, safe and efficient range. This single acting control is made of galvanized steel for low maintenance and corrosion resistance. It has integral anchor points and self- aligning, self-centering rocker bearings for long lasting service. A cushioned stop minimizes rattle and noise. Adjustment is easily accomplished by moving counter weight on outside tab.

Z-one valves are used to automatically shut-off the flow or redirect hot and chilled water in hydronic heating and air conditioning systems. The motorized two position, on/off/, spring return A1 series actuator has an end mounted push button for quick installation to valve body. The actuator is equipped with or without auxiliary switch and configured Normally closed or Normally Opened with wire or terminal connections.
