CEILING PLATE OPENING
Cut away the ceiling plate between the studs where the
furnace is to be installed. Work from the top in the attic. If there
is no access to the top, remove the wall covering between the
two wall studs all the way to the ceiling. Work through this
opening. Cut out the entire plate so the plate edges will be even
with the inner face of the 2 x 4 studs. Figure 7
INSTALL VENT BASE PLATE (HOLD-DOWN PLATE)
Position base plate on top of header plate and fasten with
screws. Note: Hold down plate is not included.
HEADER PLATE (VENT SUPPORT)
Measure upward 62¼-inches from the top of the floor plate.
Place a mark on each stud at this distance. Figure 5A, 5B. Place
the header plate between the studs with the lower edges even
with marks on the studs. Make sure header plate is level.
Locate rear edge of nailing tabs at back of the header. Nail
header plate to the 2 x 4 studs which will center the vent collar
in the wall. Figure 5A, 5B
INSTALL CEILING PLATE SPACER
Nail the ceiling plate spacers either across or in between the
cut out section of ceiling plate. If nailed between, ends must
be bent at 90 degrees. They must be fastened along each long
edge of the ceiling plate hole to hold the oval vent pipe in the
center of the hole. Ceiling plate spacers preserve structural
strength and position oval vent pipe in the center of the cut out
opening. Ceiling plate spacers are not included. Figure 7
