3 Serpentine units offer outputs from 8,030 to 35,900 BTU s ( to kW) and are ideal for hot WATER (only) installations with limited clearances. Header type HORIZONTAL units range from 18,000 to 360,000 ( to kW) and can operate with either hot WATER or STEAM . Both units are furnished Figure 1 SerpentineType Indicates an imminently hazardous situation which, if not avoided, will result in death, serious injury or substantial property damage.

The designs are certified by ETL to and UL1995. Do not alter these units in any way and do not attach any ductwork to the units. If you have any questions after reading this manual, contact the Failure to comply with the general safety information may result in extensive property damage, severe personal injury or death. Do not alter the unit heater in any way or damage to the unit and/or severe personal injury or death may occur! Disconnect all power supplies before installing or servicing the heater. If the power disconnect is out of sight, lock it in the open position and tag it to prevent unexpected application of power.

5 Failure to do so could result in fatal electric shock, or severe personal injury. Insure that all power sources conform to the requirements of the unit heater or damage to the unit will result!Follow installation instructions CAREFULLY to avoid creating unsafe conditions. All external wiring must conform to applicable current local codes, and to the latest edition of the National Electric Code ANSI/NFPA No. 70. In Canada, all external wiring must conform to the Canadian Electric Code, Part 1 CSA Standard All wiring should be done and checked by a qualified electrician using copper wire only. All STEAM and hot WATER connections should be made and leak-tested by a suitably qualified individual, per instructions in this manual. Also follow procedures listed on the unit Equipment Start-Up Sheet located in this certain that the power source conforms to the electrical requirements of the heater.

6 Do not depend upon a thermostat or other switch as sole means of disconnecting power when installing or servicing heater. Always disconnect power at main circuit breaker as described above. Failure to do so could result in fatal electric attention must be given to any grounding information pertaining to this heater. To prevent the risk of electrocution, the heater must be securely and adequately grounded. This should be accomplished by connecting a grounded conductor between the service panel and the heater. To ensure a proper ground, the grounding means must be tested by a qualified SAFETY INFORMATIONDo not insert fingers or foreign objects into the heater or its air moving device. Do not block or tamper with the heater in any manner while in operation or just after it has been turned off, as some parts may be hot enough to cause meet ETL and OSHA requirements, units mounted below 8 feet ( ) from the floor must be equipped with an OSHA fan guard.

7 It is good practice to have a shutoff switch on the electrical power lines controlling the heater. Whenever a unit is serviced, shut power off to the unit . Since these units are installed in most instances higher than 8 feet ( ), proper type of ladders or scaffolding should be used, as set up by OSHA requirements (see Notice on page 2).In industrial plants, professional maintenance crews should service this HORIZONTAL unit heaters are shipped fully assembled and may be used for STEAM or hot WATER applications. Coils are factory tested at 250 psig ( kg).Each unit is packaged individually and marked for proper identification.
