70-1990 latest edition. In Canada, all electrical connections are to be made in accordance with the CAN/CGA B149.1 or .2 installation code and/or local code and the Canadian electrical code, Part 1, CSA C22.1. Before connecting incoming power to the unit, no more than 120 volts should show at each leg to ground. Connecting a high leg to the black lead of the unit will severly damage many electrical components in the unit and void all warranties. Call your local electrician or electric power supply company. NOTE: The unit will not function and the reset signal will stay on with the white wire connected to the live black wire and the black connected to neutral. An electrical schematic is located behind the left side panel of unit. A separate fused disconnect switch, or circuit breaker, must be installed for each unit. GAS SUPPLY-CSG The gas Combi-Steamer is factory available for either natural or propane gas. Check the data plate to determine the proper gas supply requirements. DO NOT attempt to use any gas other than that specified on the data plate. Conversion kits can be installed by your distributor if required. Incorrect gas supply could result in a fire or explosion resulting in severe injuries and/or property damage. To avoid possible serious personal injury, the installation must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1-1988 or latest edition. In Canada, CAN/CGA-B 149.1 Natural Gas Installation Code CAN/CGA-B 149.2 Propane Installation Code. All Henny Penny Combi-Steamers are equipped with two heat exchanger systems. One is responsible for steam production, the second for convection heat. Each individual heat exchanger is heated with a separate burner assembly. 69 CSG GAS SUPPLY-CSG RIGHT MINIMUM PULL of equipment away from wall permissible for accessibility to Quick Disconnect Device WRONG AVOID SHARP BENDS AND KINKS when pulling equipment away from wall. (Maximum pull will kink ends, even if installed properly, and reduce Connector life.) Couplings and hose should be installed in the same plane as shown at left. DO NOT OFFSET COUPLINGS – this causes torsional twisting and undue strain causing premature failure. This is the correct way to install metal hose for vertical travers. Note the single, natural loop. Allowing a sharp bend, as 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 the couplings for longest life. Closing in the diameter at the couplings, as shown at right, creates double bends causing work fatigue failure of the 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 shown at left. CABLE RESTRAINT Please refer to the illustration below when installing cable restraint on all moveable units. I-bolt is to be secured to the building using acceptable building construction practices. DRYWALL CONSTRUCTION Secure I-bolt to a building stud. DO NOT attach to drywall only. Also, locate the I-bolt at the same height as the gas service. Preferred installation is approximately six inches to either side of service. Cable restraint must be at least six inches shorter than flexible gas line. 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 maximum movement. (Minimum movement is permissible for hose disconnection.) 70 Installation – Gas Units (continued) GAS SUPPLY (continued) CSG A steam burner gas valve and dry heat burner gas valve respectively are responsible for the gas supply to the individual burners. The Combi-Steamer models CSG have manual shut-off valves, that can be reached from the front without tools. The manual shut-off valves of these units are located behind the service cover under the operator panel. To operate the valves, unscrew the 2 knurled screws and pull the service cover off. GAS LEAK TEST-CSG After the 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. If bubbles occur, it indicates escaping gas. In this event, the piping connection must be redone. Never use a lighted match or open flame to test for gas leaks. Escaping gas could cause an explosion resulting in severe personal injury and/or property damage. GAS PRESSURE-CS 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: 7-11” water column Propane: 11” water column During pressure testing note the following: 1. The Combi-Steamer and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of th...
