Exhibit 10.1

LENNOX INTERNATIONAL INC.

Long-Term Incentive Award Agreement

U.S. Employees – Vice President and Above

THIS AGREEMENT (“Agreement”) is made as of December 10, 2021 (the “Date of Grant”), by and between Lennox International Inc., a Delaware corporation (the “Company”), and __________ (“Participant”).

The Company has adopted the Lennox International Inc. 2019 Equity and Incentive Compensation Plan (as amended and restated from time to time, the “Plan”), the terms of which are incorporated by reference and made a part of this Agreement, for the benefit of eligible employees, Directors, and certain other service providers of the Company and its Subsidiaries (together, “LII”). Capitalized terms used and not otherwise defined in this Agreement have the meanings set forth in the Plan.

Pursuant to the Plan, the Committee, which has responsibility for administering the Plan, has determined that it is in the interest of the Company and its Stockholders to make the awards described in this Agreement in order to increase Participant’s personal interest in the continued success and progress of the Company, to foster and enhance the long-term profitability of the Company for the benefit of its Stockholders by offering the incentive of long-term rewards, and to encourage Participant to remain in the employ of LII.

The Company and Participant therefore agree as follows:

1. Grant of Award. Subject to and upon the terms of this Agreement and the Plan, the Company grants to Participant on the Date of Grant an award of 1,597 service-based Restricted Stock Units (“RSUs” and such award, the “RSU Award”).

2. Restrictions on Transfer. Subject to Section 15 of the Plan, neither the awards evidenced hereby nor any interest therein or in the Common Shares underlying such awards shall be transferable prior to settlement other than by will or pursuant to the laws of descent and distribution.

3. Conditions for Vesting. Subject to Participant’s compliance with the terms of this Agreement, the RSU Award will vest on December 10, 2023 (the “RSU Vesting Date,” and the period from the Date of Grant until the RSU Vesting Date, the “RSU Restriction Period”). If the RSU Vesting Date is not a day on which Common Shares are traded on a U.S. national securities exchange or quoted in an inter-dealer quotation system, then the RSU Vesting Date will be the preceding day on which sales of Common Shares were reported.

(a) Forfeiture. Any RSU Award that does not become vested as described in this Section 3 will be forfeited, including, except as provided in Section 4, if Participant ceases to be continuously employed with LII prior to the end of the RSU Restriction Period.

4. Termination of Employment; Change in Control. Unless otherwise determined by the Committee in its sole discretion, and notwithstanding anything herein to the contrary, the RSU Award will be subject to vesting or cancellation in connection with the events specified below:

(a) If, prior to the end of the RSU Restriction Period, Participant violates

Section 8 of this Agreement or is terminated by LII for Cause (as defined in any applicable employment agreement between LII and Participant or as determined by the Committee in its sole discretion in the absence of any such employment agreement), then, immediately after LII becomes aware of a violation of Section 8 or Participant’s termination, the RSU Award will be cancelled.

(b) If, prior to the end of the RSU Restriction Period, Participant terminates employment with LII voluntarily, then, immediately after Participant’s termination, the RSU Award will be cancelled.

(c) If, prior to the end of the RSU Restriction Period, Participant is terminated by the Company without cause, then the RSU Award will vest fully as of the date of termination.

(d) If, prior to the end of the RSU Restriction Period, Participant dies or incurs a Disability, then Participant, or in the event of Participant’s death, Participant’s beneficiary, will vest in a pro rata amount of the RSU Award based upon the portion of the RSU Restriction Period during which Participant served as an employee of LII, determined as of the date of death or Disability, and the remainder of the RSU Award will be cancelled. For purposes of this Agreement, “Disability” means permanently disabled (completely unable to perform Participant’s duties as defined in the benefit plans of the Company).

(e) If a Change in Control occurs prior to the end of the RSU Restriction Period, Section 12(b) of the Plan shall apply. If a Change in Control occurs after the end of the RSU Restriction Period, Section 12(b) of the Plan shall not apply.

5. RSU Payment Timing.

(a) General. Except as otherwise provided in Section 5(b), vested RSUs will be paid within 30 days following the RSU Vesting Date. Vested RSUs will be paid in the form of one Common Share for each vested RSU.

(b) Other Payment Events. Notwithstanding Section 5(a), to the extent that the RSUs are vested on the dates set forth below, payment with respect to the RSUs will be made as follows:

(i) to the extent the RSUs are vested as a result of Section 4(c) in connection with Participant’s termination without cause, such vested RSUs will be settled by issuing to Participant one Common Share for each such vested RSU within 30 days after the date of termination;

(ii) to the extent the RSUs are vested (and have not previously been settled) as a result of Section 4(d) in connection with Participant’s death or Disability, or as a result of Section 4(e) in connection with a Change in Control, such vested RSUs will be settled by issuing to Participant (or Participant’s beneficiary) one Common Share for each such vested RSU within 60 days after the date of such vesting event; but

(iii) notwithstanding Section 5(b)(i), if Section 409A of the Code applies to the RSU Award and settlement is triggered (A) by Disability and such Disability does not constitute “disability” for purposes of Section 409A(a)(2)(C) of the Code or (B) by a Change in Control and such Change in Control does not constitute a “change in control” for purposes of Section 409A(a)(A)(v) of the Code, then payment of the RSUs will be made within 60 days after the earliest to occur of (w) the RSU Vesting Date, (x) Participant’s death, (y) Participant’s “disability” for purposes of Section 409A(a)(2)(C) of the Code (“409A Disability”), or (z) the occurrence of a Change in Control that constitutes a “change in control” for purposes of Section 409A(a)(2)(A)(v) of the Code (a “409A Change in Control”); and

(iv) in no event shall Participant be permitted to designate the taxable year of payment for the RSUs.

6. Withholding for Taxes. To the extent that the Company is required to withhold federal, state, local or foreign taxes or other amounts in connection with the delivery to Participant of Common Shares or any other payment to Participant or any other payment or vesting event under this Agreement, and the amounts available to the Company for such withholding are insufficient, it shall be a condition to the obligation of the Company to make any such delivery or payment that Participant make arrangements satisfactory to the Company for payment of the balance of such taxes or other amounts required to be withheld. Unless otherwise determined by the Committee, such withholding requirement shall be satisfied by retention by the Company of a portion of the Common Shares to be delivered to Participant. The shares so retained shall be credited against such withholding requirement at the fair market value of such Common Shares on the date the applicable benefit is to be included in Participant’s income. In no event will the fair market value of the Common Shares to be withheld and/or delivered pursuant to this Section 6 to satisfy applicable withholding taxes exceed the minimum amount of taxes required to be withheld.

7. Adjustments. The number of Common Shares subject to each award granted hereunder and the other terms and conditions of the grants evidenced by this Agreement are subject to adjustment as provided in Section 11 of the Plan.

8. Protective Covenants.

(a) Noncompete Obligations. For one year following the effective date of Participant’s termination of employment with LII (the “Termination Date”), Participant will not participate in any way in any activities within the same geographic area where Participant had responsibility to conduct business activity prior to the Termination Date, on behalf of a business that provides products or services that are the same or similar to products or services offered or planned by LII as of the Termination Date.

If Participant violates Section 8(a), Participant must pay LII on demand an amount equal to the sum of the pre-tax gains received from RSU Awards that vested under this Agreement in the one year period prior to the Termination Date, up to a maximum amount of the following multiple of Participant’s annual base salary in effect on the Termination Date: .75 if Participant is a Vice President or 1.5 if Participant is an Executive Vice President.

(b) Non-Solicitation Obligations. For one year following the Termination Date, Participant will not, directly or indirectly: (i) solicit, recruit or hire any person who is an LII employee as of the Termination Date; or (ii) solicit or induce any customer, supplier or distributor as of the Termination Date to cease or reduce doing business with LII, or divert an LII business opportunity.

The existence of this Agreement will not affect the right or power of LII or its Stockholders to accomplish any corporate act.

10. Restrictions Imposed by Law.
