INSTALLATION INSTRUCTIONS
WHITE-RODGERS

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE

INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY

AND/OR PROPERTY DAMAGE.

The multi-function gas controls combine into a single
package the functions of 3-position gas cock, main gas
valve, pressure regulator and 100% shut-off automatic
pilot. The pilot gas outlet accepts a 1⁄4” pilot line connec-
tion.
This model features a slow opening main valve that
provides a softer ignition and E.C.O. connections.
To permit replacement of a variety of valve sizes, some
models are furnished with two reducer bushings (two 3⁄4”
to 1⁄2”). Also included is an E.C.O. jumper wire that allows
this valve to be used on an installation without electrical
cut off device.

Operator: Save these instructions for future use!
