Product Overview

2 L61, L62 Series BASO Safety Shutoff Device Product Bulletin
Product Overview
L61
The L61 is an automatic resetting device that opens
the main gas valve electrical circuit if the pilot flame is
extinguished. Lighting or relighting the pilot burner
causes the device to close the main gas valve
electrical circuit, allowing the appliance main burner to
operate.
The L61 receives its energy from a heated
thermocouple. Because the L61 has automatic
resetting, minor pilot flame fluctuations, which may
cause the device to drop out, will not shut down the
appliance permanently. The L61 device will
automatically close and restore service upon
resumption of a normal pilot flame.
L61 models are available with Single-Pole
Double-Throw (SPDT) switching action when an
additional switching function, such as a signal light, is
desired.
L62
The L62 has a manual reset feature, and is available
in models with or without 100% shutoff. The L62 has a
thermo-electric power unit assembly that receives its
energy from a heated thermocouple. If the pilot flame
is extinguished, the main valve circuit is interrupted
and gas flow to the main burner (and pilot in 100%
shutoff models) is stopped. Both L62 models contain
an electric interruption feature that only allows pilot
gas flow during the lighting or resetting cycle. When
lighting the pilot, the main valve electrical circuit is
interrupted until the pilot flame is established and the
reset button is released.

Mounting
L62 safety shutoff devices can be mounted in any
position; however, the L61 must be mounted in the
vertical position only, with the thermocouple
connection down.
Both the L61 and L62 can be mounted in any
convenient location by fastening the unit to a control
panel or to the appliance using the mounting holes on
the back of the case.
