All field vent hoods are made of heavy gauge aluminum and can be used with natural gas, LP gas or oil-fired equipment. There are five diameters ranging from 3 to 8 Inch. The concentric pipe, angled outlet deflectors, and spaced plate design allow for better heat dissipation. This type of construction minimizes the effects of heat on the outside wall. The angled hood design reduces the effects of wind on the venting system. The inner and outer pipe are a continuous structure. This allows for easy installation to power venter or vent pipe and also eliminates possible positive pressure leaks in the wall section.

• Can be used in conjunction with PVG and PVO power venters or with forced draft systems
• 7-5/8 x 7-5/8 shield for 0 clearance to combustible
• Designed for standard vent pipe and Class B type double-wall (B-Vent) connection
• Provides proper clearance between flue gas stream and wall combustible

Noisy pipes, valves, and other air-related noises are often accepted as the signs of a functioning system. Excessive pump noise, cavitation, and cascading in terminal units are considered normal. But air in system water can cause corrosion, reduced efficiency, poorly heated or inadequately cooled rooms, accelerated component wear and on-going complaints. There is a device that will keep your system free of air permanently. Less maintenance, quiet operation, fewer costs!. Unlike conventional air eliminators or air scoops, the Spirovent completely eliminates 100% of the free air, 100% of the entrained air, and up to 99.6% of the dissolved air in the system. Consisting of woven copper wire soldered to a copper tube, the patented Spirotube creates a low velocity area in the Spirovent that scrubs the bubbles from the water. The air bubbles rise and collect in the air chamber before they are vented from the system via an integral automatic valve. Air problems become a thing of the past.

• Maintenance free
• No venting required
• Vent head is designed to stay dry, dirt and leak resistant
• 1/2" male thread port for pressure testing or remote venting of unwanted gases
• Quiet operation
• Increased component life
• Reduced oxygen based corrosion and pump cavitation
• The automatic air vent is guaranteed not to leak and can only be closed by the installer for a pressure test
• The air chamber has been designed so that dirt cannot reach the valve
• Large capacity collection chamber reduces the need for frequent draining
• Drain valve for flushing out the dirt
• Brass vent head
• Non-ferrous float
• ViTon seal and o-ring
• Copper coalescing medium

Honeywell V8043B1027 Zone Valve 2-Way Normally Open24 VAC Straight 3/4" OD

Outstanding Performance:
This damper was specifically designed with R8 insulation specification in mind to contribute to energy savings and help the system pass efficiency audits. Best of all, it helps eliminate hot and cold spots, the biggest cause of callbacks. The improved internal design creates a slower return that ensures a quiet operation.
Installation Made Easy
For fast, accurate installation with no callbacks, the TrueZONE Damper has you covered with a range of features that simplify installation in most applications:

Adjustable Range Stops  Easy to understand and set by utilizing a pushin lever. Theyre used to bleed air into the zones which helps lower pressure and reduce noise.

Push-In Terminals  The same easy wiring design used on TrueZONE Panels. No tools needed, has space for two wires.

Taping Flange  Lets you position insulation under it before sealing with foil tape.

Mechanical Position Indicator  Easy viewing through a clear window.

LED Indicator Lights  Red indicates the damper is closed and green indicates open (used in 3-wire applications)
