FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
The 36J27 combination gas valve is designed for
direct spark ignition (DSI) and hot surface ignition
(HSI) system applications. This control is equipped
with redundant and main solenoid valves that control
gas flow to the main burners, a pressure regulator
and a two-position on/off switch for regulation
and electrical shut-off of the solenoid valves. Upon
signal from an integrated furnace control, the valve
modulates outlet pressure.
