To operate the valves, unscrew the two knurled screws and remove the service cover. Open or close manual valves as desired. Gas Leak Test After piping and fittings have been installed, check for gas leaks. A simple checking method is to turn on the gas and brush all connections with a soap solution. The appearance of bubbles indicates escaping gas. In this event, the piping connection must be redone until no bubbles occur. Never use a lighted match or open flame to test for gas leaks. Escaping gas could result in fire or explosion resulting in severe injuries and/or property damage. Gas pressure The gas pressure should be measured when all other gas appliances in the kitchen are on high flame. The minimum and maximum incoming line flow pressures should be as follows: Natural: 7-10 in. water column (18-25 mb) Propane: 12-14 in. water column (30-35 mb) INSTALLATION continued During pressure testing note the following: 1. The unit and its individual shut-off valves must be disconnected from the gas supply piping system during any pressure testing of that system when test pressures exceed 1.2 psig (3.45kPa). Turn OFF main gas shut-off valve or main gas supply line. 2. The unit must be isolated from the gas supply piping system by closing its individual manual shut-off valves during any pressure testing of the gas supply piping system at test pressure equal to or less than 1.2 psig (3.45kPa). 3. If incoming pressure is over 14 in. water column (35 mb) a separate regulator must be installed ahead of the manual gas shut-off valve. To prevent damage to the control valve regulator, the first time the gas valve knob is turned to the ON position, it is very important to turn the knob very slowly. NOTE After turning on the gas, the manual shut-off valve must remain open, except during pressure testing as outlined above, or when necessary during service maintenance. Incoming pressure reading can be taken by installing a gas pressure gauge on the front of the unit’s main gas valves test port. This should be done with all gas appliances in operation on the same gas supply line. Should the manifold pressure drop below the desired level, consult your local gas utility service. Gas Hook-up RIGHT A minimum pull of appliance away from wall is acceptable in order to disconnect hook-up. WRONG Maximum pull prior to disconnect will result in kinked ends and reduce hose and connector life. INSTALLATION Utilize elbows when necessary to avoid sharp kinks or excessive bending. For ease of movement, install with a “lazy” loop. Gas appliance must be disconnected prior to continued maximum movement. (Minimum movement is permissible to disconnect gas line. Couplings and hose should be installed in the same plane as shown at left. DO NOT OFFSET COUPLINGS. This results in twisting and undue torsion causing premature failure. Correct way to install metal hose for vertical traverse. Note single, natural loop. Allowing a sharp bend, shown at right, strains and twists the metal hose to a point of early failure at the coupling. Maintain the minimum or larger bending diameter between couplings for the longest life. Couplings too close together, as shown at right, create double bends causing work fatigue failure of fittings. In all installations where self-draining is not necessary, connect metal hose in a vertical loop. DO NOT CONNECT METAL HOSE HORIZONTALLY unless self-draining is necessary. Then use support on lower plane as show at left. Cable Restraint Please refer to the illustration at left when installing cable restraint on all moveable gas appliances Eye-bolt is to be secured to the building using acceptable building practices. Dry wall construction Secure eye-bolt to a framing stud. DO NOT attach to dry wall only. Locate eye-bolt at the same height as the gas service approximately 6 in. (150 mm) to either side of service. Cable restraint must be at least 6 in. (150 mm) shorter than flexible gas line. ...
