Maintain a clearance of 12" from the wall to the vent terminal cap for stability under wind conditions. Products of combustion can cause discoloration of some building finishes and deterioration of masonry materials. Applying a clear silicone sealant that is normally used to protect concrete driveways can protect masonry materials. If discoloration is an esthetic problem, relocate the vent or install a vertical vent.

Mfg No. 164771, Page 11 8. Duct Connections and Ductwork Both inlet air ductwork and supply air discharge ductwork are required unless the heater is equipped with an optional inlet base and/or an optional discharge plenum. IMPORTANT NOTE: If a Model ACU cased cooling coil is part of the installation, it must be installed before attaching discharge ductwork. Installation of a filter cabinet is recommended when a cooling coil is installed. Discharge Duct Connection -The discharge duct connects to the top of the heater or to the outlet of the optional cooling coil cabinet. See Figures 10 and 11. Connect the ductwork plenum to the duct flange as illustrated in Figure 11. 1) The duct connection on the top of the heater has a 90° flange. 2) The duct may either have no flange or a 90° flange. 3) Position ductwork around the outside of the heater flange. 4) If the ductwork has a flange, drill holes vertically through duct flange into the top of the heater and secure with sheetmetal screws. If the ductwork does not have a flange, drill holes horizontally through the ductwork and the heater flange; secure with sheetmetal screws. 3,D ./7!

Corner indicators for the opening are provided on the right side, the left side, and the rear of the heater. (See Dimensions in Figure 1, page 3.) Determine where the inlet air opening(s) should be and cut out using tin snips or aviation shears. CAUTION: Form 405, Page 12 The cut edges of the metal will be sharp. If installing an optional filter or filter/mixing cabinet shipped with the heater, attach the cabinet at the "cutout" opening (See Optional Accessories, Paragraph 18 or 19). Depending on the cabinet and how it is installed, the inlet opening may be horizontal or vertical. Attach the ductwork to the heater or to the inlet cabinet. Figure 12 - Duct Opening for Connecting the Inlet Air Duct to the field-installed Filter or Mixing Cabinet Depending on the heater size and whether the cabinet is on the side or the rear, the inlet opening may be either vertical (on the top of the filter cabinet) or horizontal (on the side of the filter cabinet.) 367. 5E55'+ 3'8?8. 5E855' 3'8885E855'+ 3'4':?485E455'+ 3F4':?44567 Requirements and Suggestions for Connecting and Installing Ducts • Type of Ductwork - The type of duct installation to be used depends in part on the type of construction of the building. • Ductwork Material - Rectangular duct should be constructed of not lighter than No. 26 U.S. gauge galvanized iron or No. 24 B & S gauge aluminum. • Ductwork Structure - All duct sections 24 inches or wider, and over 48 inches in length, should be cross broken on top and bottom and should have standing seams or angle-iron braces. Joints should be S and drive strip, or locked. • Through Masonry Walls - No warm air duct...
