Install right door by holding it vertically over
the right sidepiece. Position the door so that
the door hinges will fit into the hinge brack-
ets that are welded onto the sidepiece. Line up
the holes in the hinges with the hinge pivot holes
in the brackets. Insert the 5/16" x 1-1/4" hinge
pins and cotter pins. Install the left door in the
same manner.
CAUTION: A safety latch has been provided on
the lower hinge of each door to prevent the
doors from being blown or knocked shut. Disen-
gage the safety latch by lifting the operating arm
while at the same time closing the door. (Close
the left door first.) Care is necessary at this time
as the doors are being operated without the
assistance of the torsion rods.
Check alignment. If bottom edges of doors
do not form a straight line,
move lower end
of unit to right or left to correct. Recheck
frame to insure that it is level and plumb.
Secure with bracing. Open doors. Coat top of
wall with bonding agent. Mix concrete. Pour
capping and close doors to recheck alignment.
Be sure capping is level to prevent water accu-
mulation around base of door frame. After con-
crete hardens remove forms and tighten all
screws. Caulk all around the exterior of the
frame where it meets the masonry. Water-
proof outside of wall at capping joint.
IMPORTANT! An interior door at the bottom of
the steps is required to prevent heat loss and
reduce condensation.
With the Bilco basement door now solidly
anchored, the torsion rods should be in-
stalled. There are four torsion rods. Two
are marked 1 and two others are marked 2 .
These markings can be found on the plastic
components of the rods. Each door panel re-
quires one 1 and one 2 torsion rod.
Before installing rods, apply lubricant to
plastic components per sketch included with
packet containing lubricant vial.
Open both doors so safety latches are engaged.
To install torsion rods on the left door:
Refer to #6B. Insert the hooked end of the 1 rod
into the upper hinge bracket through the hole as
shown in the diagram. Insert the "L" shaped end
of the rod UP into its retainer. Insert the hooked
end of the 2 rod into the lower hinge bracket
and insert the "L" shaped end of the rod DOWN
into its retainer BEING SURE THIS ROD PASSES
UNDER THE 1 ROD. The pressure of one rod
on the other keeps both rods in place.
To install torsion rods on the right door:
Refer to #6C. Insert the hooked end of the 1 rod
into the lower hinge bracket through the hole as
shown in the diagram. Insert the "L" shaped end
of this rod UP into its retainer. Insert the hooked
end of the 2 rod into the upper hinge bracket
and insert the "L" shaped end of the rod DOWN
into its retainer BEING SURE THIS ROD PASSES
UNDER THE 1 ROD. The pressure of one rod
on the other keeps both rods in place.
