3 Introduction Congratulations on your selection of the LIFEBREA TH Clean Air Furnace (CAF). This is a very advanced unit that combines the outstanding efficiency and economy of the water heater/airhandler concept, plus the tremendous health benefits of year-round fresh air ventilation in every room of your house.
4 Description and Purpose IMPOR T ANT NOTE The purpose of this manual is to act as an installation guide only for the LIFEBREA TH Clean Air Furnace. Manufacturers' instructions for other components, such as the water heater/boiler , must be followed.
Closed/Open Combo S y stem From the aspect of delivery of domestic hot water and space heating, the Open and Closed systems operate the same. A system becomes closed when a backflow prevention valve or check valve is installed in the cold water piping upstream of the water heater .
Call for Space Heating Only Oper ation When the thermostat calls for heat, the circulation pump is activated and hot water is drawn from the top of the water heater through the air handler , and then returned to the water heater .
Manual V alves There are a number of manual valves required for the system to operate properly and safely . These valves are used as shut off valves, drain valves and throttling valves. They can be globe, gate, ball or balancing type valves. The globe valve can be used as a shut off, drain or throttling valve.
Shut Off V alves There are 3 shut off valves required for an integrated combo system as follows: • One valve (a) 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 .
Expansion T anks Expansion tanks are only required for “Closed Systems”. The expansion tank has an air bladder , which will contract to relieve pressure in the system. Pressure is created in the closed system when water is heated in the water heater .
W ater Heat er Thermostat The water heater thermostat is set by the installing contractor to provide the required temperature at the hot water outlet of the water heater . It is important that a warning label be place near the water heater thermostat telling the homeowner not to change the thermostat setting.
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.

The purpose of this manual is to give the contractor guidelines for installing the LIFEBREA TH Clean Air Furnace. All national and local codes relating to this type of equipment must be followed.
Penetrations from sheet metal screws used to fasten the ductwork to the cabinet of the unit should only be placed into the duct flange provided. This is to avoid contact and damage of the heating/air conditioning coils and internal wiring.
Locating Intake W eatherhood The intake weatherhood should be located as follows: • 4 - 6' from ventilation exhaust hood, and upstream of prevailing winds, if possible. • At least 6' from a dryer vent, oil fill pipes, combustion outlets, gas meters, garbage containers or anything else, which may contaminate the air .
Pitot Tube Air F low Balancing It is necessary to have balanced air flows in an HRV . The volume of air brought in from the outside must equal the volume of air exhausted by the unit.
This is an example for determining the airflow in a 6" duct. The Pitot tube reading was 0.025 inches of water . From the chart, this is 640 feet per minute. The 6" duct has a cross sectional area of: = [ 3.14 x (6"÷ 12) 2 ] ÷4 = 0.2 square feet The airflow is then: 640 ft.
27 Dr ain Line The ventilation portion of the Clean Air Furnace has two drain pans for removing condensation, which may occur on the heat recovery core during cold weather .

When using a Dehumidistat or Interface Relay to initiate high speed blower operation on a furnace, certain thermostats will initiate the outdoor cooling condenser when R and G are closed. Use this wiring configuration to stop the Dehumidistat from initializing the condenser unit.
31 Start -Up Procedure In order for any appliance to work properly it must be set up and tested by a knowledgeable technician. The following conditions must be met prior to start-up 1. Ensure that connecting water lines are purged and free of debris. Caution: solder or other debris may cause the furnace pump or check valve to malfunction.
32 Oper ation Heating/Cooling When the room thermostat calls for heat, it activates a circulation pump located inside the Clean Air Furnace. This pump delivers hot water from the water heater , through the furnace coil and back to the water tank.
33 Troubleshooting Lack of heat 1. Check that the room thermostat is set to the desired temperature. 2. Confirm the units have power and the shut-off valves are open. 3. Ensure there is power to the unit and that the pump is working. If the pump is not working properly it may be stuck.
During cooling cycle, hot w ater circulates through the coil If the check valve inside the cabinet is stuck in the open position, hot water may infiltrate the heating coil. This occurs when the hot pipes are not capped-of f during installation or service and foreign debris enters the piping.
