SAFETY PROCEDURES AND PRECAUTIONS Knowledge of proper procedures is essential to the safe operation of electrically and/or gas energized equipment. In accordance with generally accepted product safety labeling guidelines for potential hazards, the following signal words and symbols may be used throughout this manual. DANGER Used to indicate the presence of a hazard that WILL cause severe personal injury, death, or substantial property damage if the warning included with this symbol is ignored.
INSTALLATION SITE INSTALLATION DANGER DANGER IMPROPER INSTALLATION, ALTERATION, ADJUSTMENT, SERVICE, OR MAINTENANCE COULD RESULT IN SEVERE INJURY, DEATH, OR CAUSE PROPERTY DAMAGE. AVERTISSEMENT : UNE INSTALLATION, UN AJUSTEMENT, UNE ALTÉRATION, UN SERVICE OU UN ENTRETIEN NON CONFORME AUX NORMES PEUT CAUSER DES DOMMAGES À LA PROPRIÉTÉ, DES BLESSURES OU LA MORT. READ THE INSTALLATION, OPERATING AND MAINTENANCE INSTRUCTIONS THOROUGHLY BEFORE INSTALLING OR SERVICING THIS EQUIPMENT.
INSTALLATION SITE INSTALLATION POSITIONING ON SITE Lift the oven from the pallet with a fork lift or pallet lift truck positioned at the front of the oven. For damage protection, the use of two wooden boards, placed between the bottom of the oven and the lifting forks, is strongly recommended. To avoid damage, position the lift forks to the left of the condenser and right of the right leg as indicated in the diagram above. Stand the oven in a level position.
INSTALLATION SITE INSTALLATION POSITIONING REQUIREMENTS q In order to ensure proper ventilation, a minimum distance of at least 6-inches (152mm) must be kept from the control panels side (left) of the oven and any adjoining surfaces. NOTE: Additional clearance is needed for service access. A minimum distance of 18-inches is strongly recommended. If adequate service clearance is not provided, it will be necessary to disconnect the gas, water, and drain to move the oven with a fork lift for service access.

INSTALLATION MOBILE EQUIPMENT RESTRAINT The gas Combitherm must use a connector that complies with The Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 CSA 6.16 and addenda Z21.69a-1989. A quick disconnect devise must be installed to comply with The Standard for Quick Disconnect Devices for Use with Gas Fuel, ANSI Z21 CSA 6.9. Adequate means must be provided to limit the movement of this appliance.
INSTALLATION VENTILATION REQUIREMENTS DANGER Installation, air adjustment and/or service work must be in accordance with all local codes and must be performed by a certified service technician qualified to work on gas appliances. 1. A single gas Combitherm oven requires a minimum of 28 CFM make-up air for natural and propane gas. Kitchen ventilation must include a provision for an adequate flow of fresh air for gas combustion and to prevent a negative-pressure condition.
INSTALLATION GAS SUPPLY & INSTALLATION The Alto-Shaam gas Combitherm has been set to operate with either natural gas or propane as indicated on the identification name plate. Make certain the gas supply matches the nameplate information. Should conversion to the opposite fuel be desired, conversion parts must be ordered from the factory. Conversion must be completed by a qualified service person only. Always remember to reflect the conversion on the oven’s nameplate.
INSTALLATION GAS SUPPLY & INSTALLATION DANGER Installation, air adjustment and/or service work must be in accordance with all local codes and must be performed by a certified service technician qualified to work on gas appliances. Remove any tape or compound residue on all external thread connections before proceeding. Use an approved gas pipe sealant at all external threaded connections, Gas piping used on gas connections must avoid sharp bends that may restrict the flow of gas to the appliance.
INSTALLATION GAS SUPPLY & INSTALLATION The minimum size requirement for gas piping or a flexible connector is 3/4 - inch (19mm). For long runs of gas piping, the pipe diameter must conform to the tables in the National Fuel Gas Code, ANSI/NFPA Z223.1. A listed gas shut-off valve must be installed upstream of the appliance to shut off the gas supply during servicing. The shut-off valve should be accessible with the appliance in the normal installation position.
INSTALLATION GAS SUPPLY & INSTALLATION LEAK TESTING If a pressure leak test above 1/ 2 psi is to be performed on the building supply gas piping, the shut-off gas valve and oven inlet gas supply line must be disconnected from the building supply piping before conducting the pressure test. Failure to do so may result in damage to the manual gas valve, gas components in the oven, or both.
INSTALLATION WATER SUPPLY & INSTALLATION WATER QUALITY REQUIREMENTS USE A DRINKING QUALITY, COLD WATER SUPPLY ONLY Water quality is of critical importance when installing steam producing equipment of any kind, particularly high temperature steam producing equipment. Water that is perfectly safe to drink is composed of chemical characteristics that directly affect the metal surfaces of steam producing equipment. These chemical characteristics differ greatly from region to region throughout the U.S.
INSTALLATION WATER SUPPLY & INSTALLATION WATER REQUIREMENTS Flush the water line at the installation site. TWO (2) COLD WATER INLETS - DRINKING QUALITY ONE (1) TREATED WATER INLET: 3/4” NPT* Install water intake filters (provided) [see figure 1] before connecting the oven to the water supply. ONE (1) UNTREATED WATER INLET: 3/4” NPT* LINE PRESSURE: 30 to 90 psi 2.8 to 6.
INSTALLATION WATER VALVE SHUT-OFF VALVE SHOWN IN THE OFF POSITION NOTE: THE SHUT-OFF VALVE MUST BE IN THE OPEN POSITION WHEN THE OVEN IS BEING USED. WATER DRAINAGE The oven must discharge through an indirect waste pipe by means of an air gap. The drain fitting is supplied with a 1-1/2-inch (41mm) NPT thread. A union is required. Install a 1-1/2-inch (41mm) diameter connection, drain line and clamp into place.
COMBITOUCH™ CHECKLIST Use this list as a final check of oven installation conformance. Damage directly attributed to improper set up, installation, or cleaning can invalidate warranty claims. CLEARANCES: Left: 6” (152mm) RECOMMENDED SERVICE ACCESS OF 18” (457mm). 20” (508mm) FROM HEAT PRODUCING EQUIPMENT.
