[. . . ] The definition of a qualified agency is: any individual, firm, corporation or company which either in person or through a representative is engaged in, and is responsible for, the installation and operation of oil appliances, who is experienced in such work, familiar with all the precautions required, and has complied with all the requirements of the authority having jurisdiction. "The Air BootTM models CAS-2B, CAS-2C and CAS-2W are for use only on the designated burner(s) as described in these instructions only when the specific burner includes this Air BootTM when shipped from the burner manufacturer or where the burner instructions specifically reference the models CAS-2B, CAS-2C or CAS-2W Air BootTM as an optional air intake system. " NOTE: This product brings combustion air only to the burner; must have adequate venting air in accordance with NFPA-31. CAS-2B CAS-2C CAS-2W BECKETT-AF/AFG CARLIN-EZ-1/CRD/FRD WAYNE-MSR 2630 Airport Road · Kinston, NC 28504 Phone: 252-522-3031· Fax: 252-522-0214 www. fieldcontrols. com THE PURPOSE OF THE VRV The Vacuum Relief Valve is a safety device to guard against combustion problems associated with directly connecting oil burners to the outside. Typical problems can be caused by blockage of the intake termination, icing up of the duct work and effects of leeward side wind effects on a building. [. . . ] Push the pan in all the way, approximately 5/8" from the air adjustment blades. (See Figure 5) Mount VRV tee assembly or 90° elbow onto the Air BootTM intake. Fasten using three (3) sheet metal screws spaced 120° apart on all joints. Mount the VRV assembly onto the tee and fasten with a screw and nut in collar tabs. To ensure proper operation, check the gate for being level across the pivot points and plumb. If mounting on the side of a building prone to drifting snow, mount 12 inches above the snow line. Mount at least 12 inches from either side of the vent termination and on the same wall if sidewall venting. NOTE: Make sure hood is kept free of debris. Page 3 Figure 4 Figure 5 Figure 6 INLET VENT TERMINATION INSTALLATION 1. Slide the inlet vent pipe through the hole and fasten to the wall with appropriate fasteners. Seal the edges of the mounting plate with a silicone sealant or equivalent. Figure 7 Figure 8 Figure 9 Page 4 DUCT WORK INSTALLATION 1. Duct length distance, a maximum of 30 linear feet of standard duct pipe and two (2) 90° elbows at maximum firing rate. Subtract 7 feet from the maximum linear feet for every 90° elbow added. Longer pipe lengths require the use of a larger pipe between the VRV and the intake hood. It also requires the use of a vent pipe increaser at the VRV and a reducer at the intake hood. (See Table 1) Table 1 Pipe Diameter Maximum Equivalent Pipe Feet (between Air bootTM and duct termination) Elbow* Equivalent Feet Reducer or Increaser Equivalent Feet 4" 5" 6" 44' 60' 90' 7' 9' 11' (4" to 5") 3' (4" to 6") 6' *Note: Subtract the elbow or reducer equivalent feet from the maximum equivalent feet to get maximum linear feet of pipe. 2. Route the duct work from the VRV tee to the inlet vent termination with as minimum a number of elbows as possible. Secure and support the duct work for the design and weight of the material used, to prevent physical damage and separation of joints. For guidelines refer to recognized national building codes or according to any local codes. [. . . ] Flow restrictor pan not installed on Beckett Burners only with inputs to . 75 or less. PROBLEM: Pump coupler failure or noisy right after installation. Supplied coupling was not installed. REPLACEMENT PARTS The following items are available for replacement, if needed. In order to replace these parts, power must be disconnected and the unit must be disassembled. [. . . ]
