Such substitutions would jeopardize the safety and health of inhabitants. The Stainless Steel non-restricted direct vent cap must be furnished by the boiler manufacturer in accordance with AGA/CGA requirements. 47 Outdoor Installation with Add-On Condensing Heat Exchanger Outdoor models are self -venting when installed with the factory-supplied non-restricted direct vent cap and require no additional vent piping. This special vent cap is provided with the boiler in accordance with AGA/CGA requirements. It must be installed directly on the boiler in a horizontal position. Notching of the vent cap mounting flange may be necessary to clear outlet piping on some models. See Section B for correct clearances. Care must be taken when locating the outdoor unit because the flue gases discharged from the vent cap can condense as they leave the cap. Improper location can result in damage to adjacent structures or building finish. For maximum efficiency and safety, the following precautions must be observed: a) Outdoor models must be installed outdoors and must use the non-restricted direct vent cap supplied by the manufacturer. b) Periodically check venting system. The boiler.s venting areas must never be obstructed in any way and minimum clearances must be observed to prevent restriction of combustion and ventilation air. Keep area clear and free of combustible and flammable materials. c) Do not locate adjacent to any window, door walkway, or gravity air intake. The vent should be located four (4) feet horizontally from such areas. d) Install above grade level and above normal snow levels. e) A venting system shall terminate at least 3 feet above any forced air inlet located within 10 feet. f) Adjacent brick or masonry surfaces must be protected with a rust-resistant sheet metal plate. g) Multiple Outdoor Vent installations require a four (4) feet clearance between vent caps. NOTICE: :Condensate can freeze on the vent cap. Frozen condensate on the vent cap can result in a blocked flue condition. The Stainless Steel non-restricted vent cap must be furnished by the boiler manufacturer in accordance with AGA/CGA requirements. The outdoor vent terminal must be installed in a horizontal position to prevent recirculation of flue products. The vent cap must be mounted directly on the vent pipe of the boiler. NOTICE: :In areas of high winds (alleyways, air handlers, etc...), a downward 90° - elbow must be mounted on the combustion air inlet to prevent any air flow fluctuation. 48 SECTION K CONDENSATE DRAIN WARNING: All condensation should be disposed of according to local, county, state, and federal laws. Refer to NFGC, section 7.9, for additional information. The Condensing Heat Exchanger (CHX) can generate up to 1 (one) gallon per hour (GPH) of condensate for every 100,000 BTUH. The maximum condensation rates for different size units are 5 GPH, 7.5 GPH, and 10 GPH for the ADB-500, 750, and 1000, respectively. Figure K-1 CONDENSATE TRAP ALIGNMENT 49 SECTION L CONTROLS WARNING: WARNING: CAUTION: CAUTION: Installation, adjustment and service of boiler controls including timing of various operating functions must be performed by a qualified installer, service agency or the gas supplier. Failure to do so may result in control damage, boiler malfunction, property damage, personal injury, or death. Turn off the power to the boiler before installation, adjustment or service of the Central Point Wiring board or any boiler controls. Failure to do so may result in board damage, boiler malfunction, property damage, personal injury, or death. This appliance has provisions to be connected to more than one (1) supply source. To reduce the risk of electric shock, disconnect all such connections before servicing. Risk of electric shock. More than one (1) disconnect switch may be required to de-energize the equipment before servicing. CENTRAL POINT WIRING (CPW) Central Point Wiring is an advanced control integration technique that provides complete boiler diagnostic capability and greatly simplifies troubleshooting. At the heart of CPW is the Operations Status Center, which is comprised of two different circuit boards: the CPW board and one or more U-2 Diagnostic Boards. THE CPW BOARD The Central Point Wiring (CPW) board serves as the central tie point for connecting all other control components in the boiler. The CPW board provides boiler operating status and fault indication using eight LEDs which function as described in Table L-1 Table L-1 CPW Board LED Indicators Light Color Indication Power Green 24 VDC is applied to the system System Error Red Overload current on the board. Board is disabled. Pump Green Boiler Pump is energized. Pilot Yellow Power applied to the Pilot Gas Valve. (PV signal on.) Main Gas Green Power applied to Main Gas Valve. (MV signal on.)
