Model 9850KXTW1 Shear Valve Configuration
The Atlas Ultra-Hi with Twin Inlet Manifold requires a special inlet configuration because of
the limited base to manifold distance. Gasboy recommends the Marrison Bros. 2 inch 636F
shear valve with a union attached at the bottom of the valve, to connect to the service system
piping.
Note: This configuration is for the Atlas Model 9850KXTW1 only. All other Atlas models
should use a standard inlet configuration.
All shear valve anchoring requirements noted in this section apply.
