Part # 4526671 (10/02/09) Page 7Gas ConnectionNOTE: The gas supply (service) line must be the same size orgreater than the inlet line of the appliance Garland Char-Broilers use a 3/4” NPT inlet Sealant on all pipe joints must beresistive to LP gasThe appliance and its individual shut-off valve must bedisconnected from the gas supply piping system during anypressure testing of that system at test pressures in excess of1/2 psi (3 45 kPa)The appliance must be isolated from the gas supply pipingsystem by closing its individual manual shut-off valve duringany pressure testing of the gas supply piping system at testpressures equal to or less than 1/2 psi (3 45 kPa)Manual Shut-Off ValveThe Manual Shut-Off Valve is supplied by the installer, it mustbe installed in the gas service line ahead of the applianceand regulator in the gas stream and in a position where it canbe reached quickly in the event of an emergencyPressure RegulatorAll heavy-duty, commercial cooking equipment must havea pressure regulator in the incoming service line for safe andefficient operation, since service pressure may fluctuate withlocal demand The manual shut-off valve is normally suppliedby the installer, but pressure regulators are shipped fromGarland with every Char-BroilerRegulators are pre-set at the factory according to thecustomer’s ordering instructions It is important to check andadjust regulator to manifold operating pressure as per ratingplatePrior to connecting the regulator, check the incoming linepressure, as these regulators can withstand a maximumpressure of 1/2 psi (14” WC) If the Line pressure is beyondthis limit, a step-down regulator will be required Double-check the arrow forged onto the bottom of the regulatorbody which shows gas flow directions; it should pointdownstream to the appliance The red air-vent cap is part ofthe regulator and should not be removed unless local codesrequire external ventingRegulators can be adjusted in the field, but it isrecommended that they not be tampered with unless thatpart is known to be out of adjustment or serious pressurefluctuations are found to exist and can be solved no otherway Any adjustments to regulators must be made byqualified service personnel with the proper test equipmentIf a vent line from the gas appliance pressure regulator isused, it should be installed to the outdoors in accordancewith local codesIn North America in the absence of local codes, in accordancewith the National Fuel code, ANSI Z223 1, Natural GasInstallation Code, CAN/CGA-B149 1 or the PropaneInstallation Code, CAN/CGA-B149 2, as applicableWARNING: Failure to install a pressure regulator will void theequipment warranty!Rigid ConnectionsDouble-check any installer-supplied intake pipes visuallyand clear any dirt particles, threading chips, or other foreignmatter before installing in a service line Those particles willclog orifices when gas pressure is appliedFlexible Couplings & ConnectorsIf the unit is to be installed with flexible couplings and/orquick disconnect fittings, for an appliance equipped withstand and casters, the installation shall be made with a heavyduty design-certified commercial flexible connector or atleast 3/4” NPT (with suitable strain relief) in compliance withall local authorities and codesIn North America connection must be in compliance with theStandard for Connectors for Moveable Gas Appliances, ANSIZ21 69/CSA 6 16, Addenda Z21 69B-2006/CSA 6 16B-2006 (orlatest edition), and a quick-disconnect device that complieswith the Standard for Quick Disconnects for Use with GasFuel, ANSI Z21 41/CSA 6 9, Addenda Z21 41A-2005/CSA6 16A-2005 (or latest edition), and adequate means must beprovided to limit the movement of the appliance withoutdepending on the connector and the quick-disconnectdevice or its associated piping to limit the appliancemovement and the location(s) where the restraining meansmay be attached to the appliance shall be specifiedINSTALLATION Continued
