As a rule this unit should be installed adjacent to the hot water heater If this is not possible or if the piping layout is complex the total head pressure on the pump should be calculated Duct Connections To accommodate various installations the Clean Air Furnace has knockouts for the return air plenum and ventilation ducts on both sides of the cabinet Special care and attention should be given to determining which knockouts are to be removed Slide Heat Recovery Core out to remove ventilation Knockouts Never install ductwork directly to the cabinet that is smaller than the opening provided Option 1 Ventilation Ports Off Left Side Models 40DHW 60DHW amp 4TONDHW Remove circular metal knockout Remove styrofoam knockout Models 40DHWDF amp 60DHWDF Remove styrofoam knockout Remove styrofoam knockout NOTE Return plenum opening can be on either side of cabinet and is not dependent on which side the ventilation ports are on Option 2 Ventilation Ports Off Right Side Models 40DHW 60DHW amp 4TONDHW Remove circular metal knockout Remove styrofoam knockout AAAA Models 40DHWDF amp 60DHWDF Remove styrofoam knockout Remove styrofoam knockout Horizontal Version Models 40DHW 60DHW amp 4TONDHW Remove circular metal knockout Penetrations from sheet metal screws used to fasten the ductwork to the cabinet of the unit should on

10. Head pressure is measured in feet or water millimeters of water Note Although the water in the combo system is pressurized by the domestic water system the pump is required to create water flow in the heating loop The domestic water system applies the same pressure to the supply and return sides of heating loop 11 Note The vertical height of the heating loop does not impact on the head pressure as the pressure required to push the water up the vertical height is offset by the weight of the water in the vertical drop on the other side of the heating loop Flow Rate Flow rate is the amount of water flowing in the system It is directly related to the head pressure and the resistance to flow Flow rate is measured in gallons per minute liters per minute Pressure Drop PD Pressure drop PD is the reduction in total pressure caused by components added to a piping system such as coils valves and fittings The measurement of pressure drop is the difference in pressure on the inlet side of the component and the outlet side Pressure drop is measured in feet of water millimeters of water When connecting the water lines for heating loop air handler to the domestic water system the pipes should be connected with a tee to the side of a vertical domestic water pipe or the bottom of a horizontal domestic water pipe This is to help prevent air from entering the heating loop The connections should be as near as p

13. the combustion gases can be 1000 F 538 C above the return air temperature These units typically have a temperature rise from 50 F 10 C to 90 F 32 C and therefore delivers air at the diffuser at 120 F 49 C to 160 F 71 With an Integrated Combo System the hot water temperature is approx 130 F 54 C which is 60 F 15 5 C above the return air temperature These units typically have a temperature rise of 35 F 2 C to 40 F 4 C and therefore would deliver air at the diffuser at approximately 105 F 40 5 C to 110 F 43 Design vs Field Conditions The factors discussed above become very important to consumer comfort Even small differences between design parameters and actual field conditions can impact greatly on output capacity Therefore it is important to do a thorough and complete commissioning of the integrated combo system to ensure the design parameters are met Water System Pressures Within the water system of an Integrated Combo system there are three terms that the designer installer must understand These are head pressure water flow rate and pressure drop Head Pressure Head pressure is the pressure created by the circulation pump to push water through the piping system It is this pressure which is used to overcome the resistance to water flow friction caused by the water pipe and fittings It is similar in concept to the external static pressure in an air duct system
14. the open position a full bore ball valve has very little resistance to flow and these valves tend to be both the least expensive and the least susceptible to seizing over time Do not use reduced bore ball valves as they are very restrictive to water flow The balancing valve can be used as a throttling valve It can make small flow changes easily and has lower resistance than a globe valve This valve will be considerable more expensive Globe Valve Gate Valve HH Shut Off Valves There are 3 shut off valves required for an integrated combo system as follows One valve on the cold water side of the water heater upstream of the heating loop connection This valve has the ability to isolate the hot water domestic and space heating from the household cold water supply This valve is required on every water heater whether or not the water heater is used for space heating One valve b on the hot water supply side of the heating loop downstream of its connection to the domestic water One valve c on the return side of the heating loop upstream of its connection to the domestic cold water The two valves in the heating loop allow the heating loop to be isolated for service or repair c Return SHUT OFF VALVES Drain Valve A drain valve is required to allow the heating loop to be drained for service or repair and to remove air from the heating loop when commissioning a system The drain va
