MOUNTING
1. Locate mounting bolts (4) on side of TFP cabinet
for vertical hanging (Fig. 3) and remove.
2. Measure distance between the bolts and mark it
on the floor/header joist where the TFP is to be hung.
3. Fasten hanging straps to floor joists using wide
head nails or screws with washers.
4. Insert hanging bolts through prepunched holes in
straps and lift TFP into position. Tighten and secure bolts.
DUCTING
1. Install (2) 7” port collars (provided) on TFP
cabinet with (8) 8/32” X 3/8” sheet metal screws
provided (Fig. 3).
