INSTALLATION INSTRUCTIONS
VR9205R Series 1000
Direct Ignition Gas Control with
Integrated Gas/Air Module
APPLICATION
The VR9205R Direct Ignition Gas Controls with Integrated
Gas/Air Module have been developed for application in
domestic appliances with premix or atmospheric burners
and automatic ignition requiring a redundant gas valve.
They have been optimized for direct ignition applications.
The gas/air module is designed to amplify and modulate
the outlet gas pressure by means of a pneumatic link
between the gas and air flow by using the air pressure
difference. The valve may be used on either Natural gas
or LP gas applications.
• Valve capacities are shown in Table 1.
• For suffix letter designation, see Table 2.
