Skytech: ESTOP1-0H Gas Timer
Model: ESTOP1-0H
Description The ESTOP1-0H Gas Timer is an emergency shut-off, mechanical timer, and manual shut-off gas valve
designed to be installed on the inlet side of a gas appliance to enable the user to control the time gas is allowed to ow
to a gas appliance. This is a mechanical timer (no batteries or power required) that has the ability to control gas ow for
1-hour (60 minutes). In addition, both models have an emergency shut-off (red knob) that enables the user to quickly and
easily shut the gas completely OFF, should the need arise.
The ESTOP1-0H Gas Timer body is 4-inches high x 2 ⅞-inches wide x 2 ⅛ -inches deep and can replace a manual
shut-off valve and meet local code requirements as the accessible shut-off valve. It can be use for multiple applications
(indoor or outdoor) from gas re pits, gas grills, gas logs, gas torch lights, etc., anywhere a shut-off valve is a required or a
specied by a manufacturer, code requirement or customer.

Mounting
The ESTOP1-0H Gas Timer has the ability to be mounted from the side of the body, using the four (4) provided holes
(two mounting holes per side) or using the two mounting hole tabs at the top and bottom of the body when facing forward.
Each mounting hole uses 3/16 - 24 machine screws to secure it into position. Note: We recommend using stainless steel
screws for any outdoor applications. See Fig. 1 for details.

Skytech: ESTOP1-0H Gas Timer
Installation
The ESTOP1-0H is designed to be installed in an up-right
position as shown in Fig 3, view "D" or Fig. 4. It has two
(2) inlet and two (2) outlet gas connections. The diagrams
below provide possible ways to plumb the timer (See Fig. 3).
Two (2) ½” NPT plugs are provided with the timer. Plug the
inlet and outlet connections not being used for the
application. Connect gas supply to the inlet with the
arrow pointing into the valve. Connect outlet side to the
gas appliance (See Figs. 2 & 3 for details).
NOTE: Conduct a gas leak test on the ESTOP1-0H Gas
Timer after plumbing is complete.
Operation
TO TURN ON
Step 1: Rotate the clear timer dial past 20 (ESTOP1-0H)
to set the time. Timer will begin “ticking” when the dial is
turned while the countdown time is set.
Step 2: Turn red knob clockwise (about a ¼ turn) until it
pops outward. Gas will now ow to enable you to light the
appliance.
TO TURN OFF: Let timer expire or simply press red knob
inward until it stops. The red knob will lock down with a
“click” and stop gas ow. See Fig. 4 and Fig. 5 on following
page.
CAUTION: Do not force the timer dial to the OFF position
after time is set. This will weaken the spring inside the timer
body and can affect the accuracy of the time. If it is
necessary to shut the timer OFF simply press the red knob
inward to stop operation. The timer will turn itself OFF
when the time expires.
Timer Dial:
Rotate clockwise to
start time. Adjust dial to
desired time frame.
Red Knob: Turn
clockwise and knob
will “pop” up to allow
gas flow.
