with the vestibule over either door. At points 1 to 12 (Figure 4) on the

inside of the tent fly you will find ⅝" side release buckles. Attach these

points to their mates on the tent body. It is easiest if you start at the

points nearest the

apex and work

down. At points

J and K on the

fly you will find

Velcro

®

attach-

ments. Attach

these to the vesti-

bule pole. At

eight perimeter

points on the fly

are ¾" LadderLoc

fly attachments (Figure 5). These points correspond to the ends of the

poles at points A–H. Working your way around the perimeter of the tent,

hook the grommets at the ends of the adjustment straps over the pole

ends at points A, B, G and H and then tighten the adjustment straps.

Working your way around the tent again, follow the same procedure for

points C, D, E and F. Now stake out the adjustable vestibule loops at

points L and M. Tighten these to the desired tautness.

Ventilation

Proper ventilation is essential for creating a comfortable

living space inside your tent. The vestibule door panel

can be rolled away for maximum ventilation, or guyed out

in an awning-like fashion. Because the rainfly has an

awning over the door, you can often leave the door tied

open in a rain storm, provided the door faces away from

the wind. When the door in the rear of the rainfly is left

fully or partially open, it effectively improves flow-

through ventilation. Additionally, the zippers at the top

of the vestibule and back door can be used to regulate

ventilation. Staking out the center back of the rainfly

(point N) further enhances ventilation by increasing airflow under the fly.

Internal Guy System

Years ago, Sierra Designs was the first to introduce the revolutionary

Internal Guy System. This system remains a very important feature in our

Convertible and 4-Season tents. When installed, this simple system will

greatly increase the strength of your tent with the weight of a few guy

cords. This system is very useful in extreme weather conditions, but is not

necessary under normal conditions.

Installation: All attachments are made inside the tent. All that is need-

ed are 4 pieces of guy cord of 100" lengths or longer, (line tighteners may

be used but are optional). Some of these items have been provided com-

plimentary with your tent.

There are nine webbing

loops sewn to the interior

of the tent body; one in

each corner of the floor at

points A, B, G and H

(Figure 6) and one at each

of the pole intersection

points in the ceiling at

points O, P, Q, R and I.

Start by tying one end of a cord through the webbing loop in the ceiling at

point Q. Secure the other end at point A with a double half-hitch or one of

the complimentary line tighteners (See Figure 7). Repeat this procedure for

lines between points B and O, G and R, H and P. Note: Point I is the

apex of the tent and it is not part of the Internal Guy System. Use point I

as a hang loop. The Internal Guy System will partially obstruct the door-

way. If you want to stow the cord out of the way when entering or

exiting the tent, simply loosen the cord and pass it through the

loop in the ceiling.

Please note that 11 tent stakes and 12 guy cords

were provided with this tent as a courtesy. If

you choose to use more than this when

pitching your tent, additional stakes and

cord may be purchased at the store where

you originally purchased your tent.

First Pitch

In order to familiarize yourself with your new tent, we suggest that you

“test pitch” it before embarking on a wilderness trip.

Select a Site

Look for a level spot that is protected from the wind in order to ensure

sleeping comfort. Clear the area of debris such as sharp stones and sticks

which might abrade or puncture the tent floor. Choose an area that will

drain well when it rains.

Unfurl the Tent and Assemble the Poles

Unfold the tent and lay the floor flat on the ground with the door un-

zipped. Carefully unfold the shock corded pole sections and allow them to

slide together. Do not allow the poles

to snap together: This can lead to seri-

ous pole damage. Make certain that

the insert of each pole section is fully

inserted into the next pole section (Fig-

ure 1). You will have two straight

poles, two arch poles of equal length,

and one shorter arch pole.

Stake Out the Floor

We recommend staking the floor prior to inserting the poles for greater

pitching ease. Although the Tiros AST is a totally freestanding tent, we

suggest that you always stake the floor for greater safety and stability, es-

pecially in high winds. First stake each of the webbing loops at the back

of the tent at points G and H

(Figure 2). Next, move to the

front of the tent, pull the web-

bing loops at points A and B

until the tent floor is squarely

and semi-tautly positioned, and

stake them down. Finally, stake

the sides at points C, D, E and

F, again pulling the tent floor

semi-taut.

Erect the Tent

Insert the tips of one of the poles into the grommets at points A and H,

and the tips of a second pole into the grommets at points B and

G (Figure 2). Pull the two poles up so they in-

tersect at point I and attach the Clip-Loc

™

over the intersection at the apex (do not at-

tach the cord yet). Now, following the seams

along the poles, attach the remaining Swift

Clips

™

. Next, insert a long arched pole at

points C and D, arching the pole around the

back of the tent. Finally, attach all Swift Clips

along this pole’s path. Repeat this process with the remaining long

arch pole between points E and F. Now that all the long poles have been

attached to the tent body, attach the 6 remaining Clip-Locs. Hook the

four Clip-Locs nearest to the doors over the intersection with their open-

ing facing the middle of the tent. Now attach the cord on the Clip-Locs

by wrapping the cord in the direction crossing the open gate of the clip.

Wrap the cord around the pole intersection two to four times, depending

on desired firmness, then slide the cord into the groove on the backside of

the clip to hold it taut (Figure 3).

Fly Sheet

You now have one remaining pole with a bent angle in it. Place the ends

of this pole in the buckets at points S and V or T and U. Drape the fly

over the tent making sure the vestibule is over the end with the vestibule

pole. Please note that the tent body is symmetrical so the fly can go on
