L62AA BASO® Safety Shutoff Device
Installation
!
WARNING: Risk of Fire or Explosion.
Do not use the L62AA in Liquefied Petroleum
(LP) gas applications. The L62AA is for use with
natural gas only. Pilot gas is not 100% shut off
and will continue to flow with the loss of pilot
flame. Use of LP gas may cause gas accumulation
and may result in severe personal injury or death.
IMPORTANT: Only qualified personnel
should install or service BASO® Gas Products.
These instructions are a guide for such personnel.
Carefully follow all instructions in this document
and all instructions for the appliance.
!
WARNING: Risk of Explosion or Fire.
Shut off the gas supply at the main manual shutoff
valve before installing or servicing the L62AA.
Failure to shut off the gas supply can result in the
release of gas during installation or servicing,
which can lead to an explosion or fire, and may
result in severe personal injury or death.
!
CAUTION: Risk of Electric Shock.
Disconnect power supply before making electrical
connections to avoid electric shock.
IMPORTANT: Make all gas installations in
accordance with applicable local, national, and
regional regulations.
IMPORTANT: Do not loosen or tighten the
brass hex nut that fastens the brass terminal
bushing to the switch housing. The machined flats
on the terminal bushing must be parallel to the
flats on the switch housing. If not, the switch power
unit may distort and cause the safety switch to fail.
To install the L62AA.
1.
Turn off power to the appliance.
2. Turn off gas at the main manual shutoff valve
adjacent to the appliance.
3. Remove the L62AA cover by loosening the
screws at the side of the device (not the brass
hex nut).
4. Mount the L62AA in any convenient position
using the mounting holes provided. See Figure 1
for mounting hole locations.
5. Push the circuit wires through the conduit
opening on the bottom of the L62AA, strip the
ends of the wires just enough to put the bare
wire under the terminal screws, and attach them
to the two wire terminals (see Figure 1).
6. Replace the cover (do not loosen the brass hex
nut).
7. Attach the thermocouple securely to the pilot
burner, and screw the terminal end to the BASO
power unit terminal on the L62AA (see Figure 1
and Figure 2). Make sure that this connection is
clean. Tighten the thermocouple lead nut finger
tight plus a maximum of 1/8 turn. Do not
overtighten.
!
WARNING: Risk of Explosion or Fire.
Do not attach both wires to one terminal on the
L62AA. Doing so bypasses and eliminates all
safety features provided by the L62AA, can lead to
an explosion or fire, and may result in severe
personal injury or death.
!
WARNING: Risk of Explosion or Fire.
Verify that this device is wired in series electrically
with thermostats and other appliance operating
controls. Wiring the device in parallel with such
controls will defeat the safety features of this
device and may result in severe personal injury or
death.
