APPLICATION
The SV9401/SV9402/SV9403, SV9501/SV9502/SV9503,
and SV9601/SV9602 SmartValve™ System Controls
combine gas flow control and electronic intermittent
pilot sequencing functions into a single unit. This
product family offers several different intermittent pilot
sequences for a wide range of applications. See Table 1
for specific sequences available. The Q3450 or Q3480
Intermittent Pilot hardware provides the low voltage
ignition, flame sensor, and pilot burner. This system is
suitable for application in a wide range of gas-fired
appliances including furnaces, rooftop furnaces, boilers,
unit heaters, infrared heaters, space heaters, water
heaters, decorative appliances, and commercial cooking
units. The specific application of the SmartValve System
is the responsibility of the appliance manufacturer. See
Table 2 for gas capacity and thread sizes.
