WHEN INSTALLING THIS PRODUCT...
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazardous
condition.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced, flame safe-

CAUTION
1. Turn off gas supply before starting installation.
2. Disconnect power supply before beginning in-
stallation to prevent electrical shock and equip-
ment damage.
MOUNTING
Electric motorized valves of this type should not be
installed in poorly ventilated pits or confined spaces for
control of combustible gas flow. The valve body may be
installed in any position provided the motor shaft is horizon-
tal. Allow sufficient clearance for assembling the motor and
linkage, and for general servicing. See Fig. 2 for installation
dimensions.
PIPING
The valve body may be piped either by screwing directly
to the pipe or by using close nipples and companion flanges.
The pipes must be in exact alignment to avoid distorting the
valve body. Ream and clean pipes carefully, and apply pipe
dope to the male threads only. Leave the first two threads free
of dope.
