Drain 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.
Piping
The hot water piping between the hot water tank and the Clean Air Furnace should be new copper type, and should not be treated with chemicals, sealant or anything else, that will interfere with the purity of the potable water. Only
Where possible the length of pipe should not exceed 200' total equivalent length. Any piping running through unconditioned space must be insulated to prevent heat loss, and possible freezing of the line.
Stickers indicating direction of flow, (Supply to furnace, and Return to water heater) are labeled on the outside of the cabinet. Do not reverse these lines, as this will cause the unit to malfunction.
For piping conventional water heaters, connections to and from the Clean Air Furnace to the water tank should be made at the point where the pipes leave the tank vertically. A "T" fitting used in each vertical line, with the Clean Air Furnace piping connected to the horizontal side of this fitting, will work best in avoiding air locks in the circulation pump of the furnace.
*Note: Remove shipping block from underneath pump and discard.
