DIRECTIONS FOR FIELD ASSEMBLING
AND WEATHERPFOOFING SECTIONS
1. Apply gasket material to the end of the fi rst section
(blower, discharge, heater, ets). (See Fig. 1.)
NOTE: One roof cap is attached to a standing seam
on each section for shipping purposes only. It will
be necessary to remove this PRIOR TO SLIDING
SECTIONS TOGETHER. Failure to do so may dam-
age seams, preventing proper seal.
2. Slide adjoining section against the tacky taped fi rst
section. If bolt holes are provided, bolt the sections
together tightly. If bolt holes are not provided, use
furniture clamps to pull sections TIGHTLY together.
Sections, whether bolted or not, will be held together
and sealed by the standing seams and hugger strips
(Fig. 2), which will be attached later.
3. Once the sections are connected, apply caulking
or silicone sealant along the standing roof seam
(Fig. 3) and side seams where the sections come
together. (Fig.1) It is mandatory to seal the roof and
side seams along the entire outside of the unit, and it
is strongly suggested that the seams also be sealed
along the inside of the unit, if possible.
4. Apply caulking material along the top of both sides of
the standing roof seam (Fig.4). Place roof cap (Fig. 4)
on top of the seam and secure it with two rows of TEK
screws (one down each side), spaced approximately
8-10 inches apart down the entire length of the seam.
5. Apply two strips of tacky tape (one down each side)
to the back side of each hugger strip (Fig. 2). Secure
hugger strip with two rows of TEK screws (one down
each side) spaced approximately 8-10 inches apart
down the entire length of the seam.
6. After hugger strips are installed, caulk around the
edges to complete the seal.
7. Repeat this process for each section as it is attached.
The number of sections varies by application.
