INSTALLATION INSTRUCTIONS

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.

DESCRIPTION

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.
