Lennox.com supplies user manuals for all of the company's products. Adobe Acrobat Reader must first be installed using the provided link to view or download the documents.
The website offers two choices for finding a desired user manual. The search option can be used to select the product category to which the item belongs. A second search bar then lists all models found in that department. Another option allows users to directly enter the model number if it is already known. Once the information has been entered, a list of results containing all literature related to that particular product appears.
