Tape
the provided template to the door. The top edge of the
cut-out line should be 1-1/4 inch (or more) above the
dog’s withers (shoulders) for the single flap door
mount, and 2 inches for the double flap wall mount. Be
careful not to unduly reduce the strength of the door by
cutting too close to the bottom of the door. Level the
top edge of the cut-out line as shown in Figure 1.
-
Mark
the hole centers for the four holes and remove the
template.
-
Drill
the four 3/8 inch holes as shown in Figure 2.
-
Draw
the cut-out lines using a straight edge as shown on the
template.
-
Cut
along the line as shown in Figure 3.
-
Install the weather-stripping into the groove on both
frames with the start/end gap at the bottom.
-
If a
single flap door mount, place the pet door trim frame on
the outside of the door and the flap frame on the
inside. If a double flap door mount, place the flap
frame with the tunnel attached on the inside and the
other flap frame outside.
-
Select
the longer set of screws for 1-3/4 inch doors and the
shorter set for 1-3/8 inch doors. Insert these into the
pet door from the inside. For doors with a thickness of
less than 1-3/8 inch, see special instructions.
-
Install the barrel nuts from the outside. Installing the
barrel nuts can be difficult. To assist in holding on to
the barrel nuts, use the plastic screw. Force the
plastic screw into the barrel nut until you hear it
click as shown assembled in Figure 4. It can then be
mated to the frame screw. Start all four screws and
barrel nuts as shown in Figure 5, but do not tighten.
-
Before
tightening down the screws, check that the pet door is
level and adjust as needed.
-
Tighten the screws until the weather-stripping
compresses and the pet door touches the door. Do not
over tighten.
-
Hammer
the hole covers into the frame using the wooden end of a
hammer (or similar non metal tool).
-
Apply
silicone along the inside of the tunnel where it mates
with the flap frames to seal your pet door from the
elements. Failure to seal your pet door can lead to
severe water damage.
