Equipment Eligibility

• Only replacement of existing deteriorated seals or the addition of new seals to an existing building with shipping/receiving dock doors that do not have any type of seal in place are eligible.
• New construction is not eligible for this offer.
• If other mechanisms that combat infiltration at the shipping/receiving door are present, such as air curtains, it is not eligible.
• The space adjacent to the door must be heated during the heating season by natural gas fueled equipment. Two types of seals (compression and shelter) are eligible based on door size. Compression seals (this is a foam pad that is wide and fixed to the door, with a min. of 40 oz vinyl cover) on 8' x 8', 8' x 9' and 8' x 10' doors.
• Shelter type seals (this is a curtain-like seal with a foam frame that compresses against the sides and top of the trailer box, with a min. of 40 oz vinyl cover) on 10' x 10' doors.
• Existing deteriorated are only eligible if the Incentive Application is approved by an Enbridge Gas representative and if the existing seal has a minimum average 2-inch gap based on a 6-point measurement outlined below.
• This measurement must be taken and provided with the application form to be eligible.

If a measurement is not provided with the application, then it is not eligible.

Where:
gap1 , gap2 , gap5 , gap6 = linear gap between the door frame and the deteriorated seals measured at the top and bottom of the side frames in inches
gap3 , gap4 = linear gap between the door frame and the deteriorated seals measured at two corners on the top door frame in inches
Average = average deteriorated seal gap (inches)

• If Average ≥ 2 in = deteriorated seal, eligible
• If Average < 2 in = not deteriorated seal, not eligible

Please note that you are measuring “absence” of the seal that was in place before but that is now torn.
