FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
The 36C03 and 36C10 series valves are designed
to meet requirements for use on standing con-
tinuous pilot systems. 36C03 combination models
include a pressure regulator, 100% shut-o auto-
matic pilot, and main operator. 36C10 models do
not have a pressure regulator.
