appropriate screws through the overlapping flanges

using a powered impact gun and taking care not to

strip the screws. Outdoor air handlers will ship with a

seam cap that is to be installed over the section-to-

section seams. Factory-supplied butyl tape must be

applied over the seam prior to seam cap being applied.

See Figure 30.

with number 10 screws. Join outdoor roof panels

together at the seams in the direction perpendicular to

airflow and secure them in place with 5/16-inch x 3/4-

inch bolts and 5/16 lock nuts. Install the roof joint strip

to cover the seam between two outdoor roof panels in

the perpendicular to airflow direction of. Use 3/8-inch

butyl tape to cover the seam between two outdoor roof

panels overhang at the side the unit. Bend joint strip

over roof panel and use two number 10 sheet metal

screws (one in each roof panel) to secure joint strip.

Trim the roof joint strip to insure that it does not

protrude more than 1/16-inch beyond outdoor roof

overhang (see Figure 31).
