Step 2 - Insert heater body all the way into duct until terminal box covers opening. Step 3 - Secure heater in place with sheet metal screws. Step 2 - Secure heater flanges to duct with sheet metal screws or bolts. Note: When flanges are aligned properly, the entire coil section should be within the air stream. These heaters are suitable for either vertical up or horizontal airflow with airflow in either direction. Observe instructions on UP label when positioning heater (see Page 2, Item 7) Note: If mercury contactors or SCRs are built into the heater, it will operate only in the position indicated by the CAUTION label. In special cases where the heater terminal box is no longer than the heater frame, refer to separate mounting instructions, Bulletin I-139. For efficient and trouble-free operation it is important that air distribution be uniform over all the heating coils in the entire heated section and particularly the area where the coils terminate. No electric duct heater should ever be operated with insufficient airflow or overheating and subsequent damage will result. The minimum velocity required at any point should be determined from the graph below. NOTE: Heating elements may retain a light surface film die to manufacturing processes.Thank you, for helping us keep this platform clean. The editors will have a look at it as soon as possible.

Product Type Infrared Heaters Resource Type Installation Information. The most common type is the electrical duct heaters. They create heat while passing an electric current through resistance (coils). The air passing through absorbs the heat out of the coils and it is then pushed through the ductwork into your rooms. Inline electric duct heaters can be used for space, supplementary, and primary heating applications. They can be programmed to heat the air only in specific times of the day, or after temperatures drop below a pre-setted value. The optimal temperature could be kept by automatically switching the heaters on and off, in compliance with readings from climate control systems. This makes inline electric heaters highly energy efficient. The first switch automatically switches off the heater after the maximum temperature is reached. The second is a manual switch with which the heaters could be turned off in case of malfunction in the automatic system. Simpler models have a set of stages. Every stage uses more energy to generate more heat. Those stages are usually three. Duct heaters are relatively easy to install and replace. Mounting can be done with airflow in either direction using a standard spigot connection to spiral ducting. Electric in-line duct heaters should always be installed with the safety cut outs at the top of the unit. These devices are designed according to dimensions, watts and current, so it is important to have the same model or at least one with the same stats. They are easy to install and maintain. That fact, combined with their energy efficiency, is the reason why those devices find many applications. Regular maintenance is highly important. Whenever you have a heating element, you should check its condition often. At least before every winter season for domestic properties. In order to choose the right one, you might need some professional help.

TOLL FREE 11 DUCT HEATER CONSTRUCTION ALL HEATRIX DUCT HEATERS ARE BUILT TO CONFORM TO U. L. AND N. E. C. REQUIREMENTS AND ARE LISTED FOR ZERO CLEARANCE heating elements open coil Heaters shall be built using Type C Nichrome wire supported in a ceramic steatite floating bushing. The ceramics are then supported by a galvanized steel frame. Standard spacing for element cross supports is 3 inches on center. Element frame assemblies are then mounted into a galvanized steel wrap.INTERNAL WIRING All wiring used shall be U. L. Listed copper105 C stranded wire. OVER CURRENT PROTECTION All heaters shall be fused in accordance with applicable U. L. standards and the national electric code. Circuit fusing is required when a duct heater circuit or circuits exceed 47.9 amps. If the circuit does not exceed 47.9 amps then circuit fusing is not required by code but may be added as a factory installed option. CONTROLS Numerous control options are available for Heatrix Duct Heaters. All options are listed in this catalog. If the pressure in the duct system is less than.07 W. C. we recommend a fan interlocking relay be used in lieu of the pressure switch. B) A fan interlock relay is available in lieu of the standard pressure switch to interlock the heater with the fan circuit.

TOLL FREE 12 FIELD WIRING All heaters will be furnished with line terminals capable of handling 125% of the connected load. Heaters requiring larger than 500 MCM incoming field feed will be subdivided into smaller feeds to meet U. L. requirements. CONTROL PANEL CONSTRUCTION A minimum of 20 gauge galvanized steel is used in construction of all heaters, heavier gauges are used on larger models.

M Models that do not include a door interlock disconnect switch incorporate a spring loaded latching device in the cover assembly. SPECIAL CONSTRUCTION Recessed elements for internally lined ducts. Flanged Mounting. Bottom or top mounting in duct. Outdoor enclosures. Modular heaters. HXOB type for mounting directly to the fan discharge. Remote control boxes. HEATING ELEMENTS Heatrix Heaters use an open coil electric heating element design. Standard elements are made of nickel chromium alloy grade C, which is 60% nickel, 20% chromium and 20% iron. This element has excellent heat resisting properties and is rated up to 1700 degrees fahrenheit. It is essentially iron free and has rating up to 2100 degrees fahrenheit. Elements are held in place by ceramic steatite floating bushings spot welded into a galvanized steel frame with cross supports no more than 4 inches on center. Elements are terminated with zinc plated studs by nuts and bolts interlocked thru ceramics bases. Stainless steel terminals are standard. Unless otherwise specified a watt density of watts per square inch is used in the design of Heatrix Heaters. TOLL FREE 13 OVER TEMPERATURE PROTECTION Both U.L. and N.E.C. require two types of over temperature protection. The primary system is an automatic reset and is designed to de-energize the control circuit of the heater if an air circulation problem arises in the duct system.

The secondary or manual reset is designed to de-energize the heater element at a higher temperature in the event of a failure in the primary system. Manual resets can be put back in operation by pressing the reset button found in the heater terminal box. However, the disc must be at a safe temperature before resetting. Manual resets are wired in the power legs. Primary and secondary over temperature devices should not be bypassed in the field because of cycling or tripping out. These devices are put there for safety reasons. If a heater has a cycling problem the problem should be eliminated. First check installation of heater, air flow, air blockage, and insufficient air. If the problem still persists, call our engineering staff and they will try to resolve any problem you have in the field. TOLL FREE 14 MAGNETIC CONTACTORS Magnetic contactors are standard in al Heatrix Heaters. One, two and three pole contactors are available with control voltages ranging from 24 volts to 277 bolts. 24 volts is standard unless specified differently. All heaters are wired using de-energizing contacts, unless specified. Disconnecting caution must be taken when using de-energizing contactors, One end of each element remains electrically hot unless a safety disconnect serving the heater is off. Mercury CONTACTORS Mercury contactors are normally used when a control system requires frequent cycles or when quiet operation is essential. Mercury contactors are more durable and have longer life expectancy than magnetic contactors. Holding coil voltages range from 24 volts to 277 volts. Since mercury contactors are position sensitive, it is of the utmost importance that installation is done according to labels found in every Heatrix Heater. Installer must install heater in position of arrow on the heater. TOLL FREE 15 AIRFLOW SWITCH Airflow switches provide the best heater protection against element failure. Airflow switches are of the pressure differential diaphragm operating type.
