       Amendment to Employee Stock Purchase Plan Dated December 15, 2000
       -----------------------------------------------------------------


The Lennox International Inc. Employee Stock Purchase Plan, as amended, is
hereby amended:

1.   The first paragraph of Section 3 of the Plan is amended to read as follows:

          "The Common Stock subject to issuance under the terms of the Plan
          shall be authorized but unissued shares, previously issued shares
          reacquired and held by Lennox or shares purchased on the open market.
          The aggregate number of shares that may be issued under the Plan shall
          not exceed 2,575,000 shares of Common Stock, which include the
          original 825,000 shares and an additional 1,750,000 shares added by
          this amendment. All shares purchased under the Plan, regardless of
          source, shall be counted against the 2,575,000 share limitation."

2.  Section 20 of the Plan is amended to read as follows:

          "This Plan was adopted by the Board on September 11, 1998, and was
          previously amended by the Board on March 12, 1999, to be effective as
          of the Effective Date. The Plan is further amended, effective January
          1, 2001, by action of the Board on December 15, 2000, to increase the
          number of shares authorized to be issued hereunder. Notwithstanding
          the foregoing, the amendment of the Plan is expressly conditioned upon
          the approval by the holders of a majority of outstanding shares of
          Common Stock within 12 months of the date of Board approval of such
          amendment. If the stockholders of the Company should fail so to
          approve this Plan as amended, this Plan shall terminate and cease to
          be of any further force or effect and all purchases of shares of
          Common Stock under the Plan after December 31, 2000, shall be null and
          void."


                                                                     Exhibit 5

Ladies and Gentlemen:

          As set forth in the Registration Statement on Form S-8 (the
"Registration Statement") to be filed by Lennox International Inc., a Delaware
corporation (the "Company"), with the Securities and Exchange Commission under
the Securities Act of 1933, as amended (the "Securities Act"), relating to the
offering of up to 1,750,000 additional shares (the "Shares") of the common
stock, par value $0.01 per share ("Common Stock"), of the Company, pursuant to
the Employee Stock Purchase Plan of Lennox International Inc. (the "Plan"),
certain legal matters in connection with the Shares are being passed upon for
the Company by me.  At the Company's request, this opinion is being furnished to
the Company for filing as Exhibit 5 to the Registration Statement.

          In my capacity as counsel to the Company in the connection referenced
above, I have examined the Company's Restated Certificate of Incorporation and
Amended and Restated Bylaws, each as amended to date, and the Plan, and have
examined the originals, or copies certified or otherwise identified, of
corporate records of the Company, including minute books of the Company,
certificates of public officials and of representatives of the Company, statutes
and other instruments and documents as a basis for the opinions hereinafter
expressed.

          I have assumed that all signatures on all documents examined by me are
genuine, that all documents submitted to me as originals are authentic, that all
documents submitted to me as copies are true and correct copies of the originals
thereof and that all information submitted to me was accurate and complete.

          Based upon my examination as aforesaid, and subject to the
assumptions, qualifications, limitations and exceptions herein set forth, I am
of the opinion that:

          1.   The Company is a corporation duly incorporated and validly
     existing in good standing under the laws of the State of Delaware.


          2.   When issued and sold from time to time in accordance with the
     provisions of the Plan, for consideration calculated pursuant to the terms
     and provisions of the Plan, the Committee of the Board of Directors of the
     Company charged with administering the Plan, the Shares will be duly
     authorized by all necessary corporate action on the part of the Company,
     validly issued, fully paid and nonassessable.

          The opinions set forth above are limited to the General Corporation
Law of the State of Delaware, and no opinion is expressed herein as to matters
governed by the law of any other jurisdiction.

          I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.

                                             Very truly yours,

                                             /s/ Carl E. Edwards, Jr.
                                             --------------------------

                                             Carl E. Edwards, Jr.

                                       2


                                 EXHIBIT 23.1
