STEP 10 (Nozzle Attachment)
Attach appliance nozzles and swivel assemblies to the pipe protruding through the underside of the range hood. Loosen the locking nut on the swivel assemblies, aim and align nozzles pointing between burners, then tighten the nuts to lock the nozzles in place. See Figure 13 for aiming the appliance nozzles.
NOTE: All pipe cuts must be reamed and deburred before assembly.
1/4" schedule 40 black iron pipe nipples and/or couplings may be used to extend the vertical position of the pipe assembly when necessary for special installations. However, the maximum overall length (including nipples or couplings) must not exceed the dimensions listed above. For additional piping assemblies see Addendum No. 71758-3 dated August 2000
TARGET AREA FOR INSTALLATION OF FIRE
DETECTION LINKS (TYPICAL TO MOST KITCHEN RANGES)
Center each fire detection link directly over each kitchen range heating element. Should the size and type of your kitchen range prevent centering, you may position a detection link no more than one (1) inch from the edge of a kitchen range element.
Distance from the detection links to the kitchen range top cooking elements shall not exceed 26 �� inches.
FAILURE TO FOLLOW THIS PROCEDURE MAY DELAY ACTIVATION OF THE GUARDIAN AND PREVENT EFFECTIVE EXTINGUISHING.

STEP 11 (Arming System)
To arm your Guardian system, turn the cable tension adjuster until the cable is tensioned and the fire extinguisher handle moves slightly upward (about �� ). The safety pull pin should slide in and out freely. When properly adjusted, the cable tension will be 14-15 lbs. (See Figure 9).
CAUTION: Too much cable tension may rearrange the prepositioned link assembly. Too little cable tension may cause the Guardian to prematurely activate when you remove the safety pull pin.
NOTE: Do not remove the safety pull pin from the valve assembly until installation of the Guardian system is complete, including any optional accessories. To remove the safety pull pin, cut the plastic safety seal and pull the pin out completely.
THE GUARDIAN IS ARMED AFTER REMOVAL OF THE SAFETY PIN.
TARGET AREA FOR APPLANCE NOZZLES
Aim appliance nozzles at the center point between the front and rear kitchen range heating elements. Distance from the appliance nozzles to the range top surface shall not be less than 18 inches or more than 28 inches.
FAILURE TO FOLLOW THESE PROCEDURES MAY RESULT IN INADEQUATE COVERAGE OF EXTINGUISHING AGENT OVER BURNER AREAS.
NOTE: Based on a tire test conducted by Underwriters Laboratories (UL), distance limitations established have proven effective in actuating Guardian Systems in accordance with U.S.A.F. 90 second response requirements for gas and electric kitchen ranges. |
