The plumbing installation should be done by a licensed plumber and must comply with local and national codes. The
water inlet line on the Rethermalizer is located on the front right side of the unit. This line feeds water to the auto fill
valves through the manual shut-off valves also located on the back of the unit. A drain line for each tank is underneath
the unit and can be inserted into a drainage system. The drain lines for each tank are connected together to form a single
common drain line. The drain line also has the overflow line from each tank connected to it. This connection is made
after the drain valve to provide an unobstructed overflow path.
Electrical Connection:
On gas machines - The electrical service used by the Rethermalizer must comply with local codes. If there are no local
codes that apply, refer to the National Electrical Code (NEC) to install the service. In Canada refer to CSA Standard
C22.1 and local codes. Wiring diagrams are provided inside the front panel of the Rethermalizer. The power
requirements for the unit are shown below.

The Gas Rethermalizer has one power cord which supplies power to the unit's controls. The unit must be grounded in
accordance with local code; if there is not a local code, comply with NEC ANSI/NFPA No. 70-Latest Edition. It is
advised that these power cords be plugged into a wall receptacle supplied from the ventilation control. This will ensure
that the Rethermalizer can not be operated unless the ventilator is also on to provide proper ventilation. Disconnect
power to the Rethermalizer before cleaning or servicing.

Ventilation and Fire Safety Systems (Gas machines only):
Your new Rethermalizer must have proper ventilation to function safely and properly. Exhaust gas temperatures can
reach as high as 1200°F. Therefore, it is very important to install a fire safety system. Your ventilation system should be
designed to allow for easy cleaning. Frequent cleaning of the ventilation system and the Rethermalizer will reduce the
chances of fire. Table 1-1 provides a list of reference documents that provide guidance on ventilation and fire safety
systems. This table is not necessarily complete. Additional information can be obtained from the American Gas
Association, 8501 East Pleasant Valley Road, Cleveland, OH 44131.
WARNING
Never stand on the rethermalizer to service or clean the hood. This can be
both damaging to t he machine and hazardous to your health.
