Built On the Job (Not Furnished by Factory) On occasion when a duct furnace is incorporated in an air handling system, it may be desirable to handle a total of more CFM than the duct furnace will pass at a given static pressure drop and temperature rise. Therefore, it is necessary to arrange to bypass the additional CFM required. The size of the bypass duct can be determined by referring to the chart. This permit ...

1. Remove “Side Access Panel”. 2. Insert Vent Sleeve of “Vent Cap Assembly” (Item 1) thru “Top Panel Assembly” (Item 2), and over Vent Collar of “Flue Collector Assembly” (Item 3). 3. Align “Vent Cap Assembly” so it is square to “Top Panel Assembly”. 4. Fasten with “Drill Screw” or “Sheet Metal Screw” (Item 4) by reaching between “Flue Collector Assembly” (Item 3) & “To ...
