Emerson White Rodgers 36H Series User Manual

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
The 36H series combination gas valve has redundant
and main solenoid valves that control gas ow to the
main burners, a pressure regulator to maintain a con-
stant outlet pressure, and a two position on/o switch
for electrical shuto. The valves are shipped from the
factory set for natural gas non-piloted applications.
See instructions in this document for modications
required if the valve is to be installed on an LP gas
and/or piloted gas application.
