SHUTOFFS

GAS: Pneumatic Gas Valve. (P/N 21 C/NM220606) Pneumatic gas valve assembly (complete with 8' stainless steel hose) (P/N GSOA/P1 OOA).

For additional gas shutoffs see Addendum No. 71758-3 dated August 2000.

APPLICATIONS AND LIMITATIONS

PNEUMATIC GAS VALVE: The pneumatic gas valve (See Figure 17) has been engineered to be installed in either a horizontal or vertical run of piping without affecting operation of the valve. Orientation of the valve in the vertical position, of course, would have no effect on its operations. Likewise, in the horizontal position, it can be oriented anywhere within a 360�  rotation. The only limiting factors to be concerned with are locating the inlet feed port (See Figure 18) of the pilot line so that installation can be easily accomplished.

The valve should be located as close to the back wall (normally behind the range) as possible to permit the range itself to be positioned as close to the wall as possible. Connect the stainless hose to the piping assembly located in the cabinet above the range hood (See Figure 19).

Should the Guardian system be activated due to fire conditions or by accident, it is suggested, but not required, for the pneumatic valve to be cleaned before returning the system to service. As a minimum, when pushing the reset button, a visual inspection should be conducted. For complete cleaning instructions, see "Gas Valve Cleaning Procedure".

The pneumatic valve pilot consists of an inner Teflon tube 3/16" ID. x 1/4" O.D. with an outer sleeve covering of stainless steel wire mesh which reinforces and strengthens the inner tubing. Swivel fittings are provided on each end of tubing for ease of installation. Crushing or collapsing the inner tubing accidentally is nearly impossible. The maximum allowable radius permitted to be formed in this line without presenting any problem is a 2" radius.
