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

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
