GENERAL  
READ ALL INSTRUCTIONS BEFORE USE  
IMPORTANT: It is the responsibility of the purchaser of  
the heater to make the ultimate choice of sheath  
material based upon his knowledge of the chemical  
composition of the corrosive solution, character of the  
materials entering the solution, and controls which he  
maintains on the process.  
FIRE/EXPLOSION HAZARD. Ordinary location  
heaters (designated E1) are not intended for use in  
hazardous atmospheres where flammable vapors,  
gases, liquids or other combustible atmospheres are  
present as defined in the National Electrical Code.  
Failure to comply can result in personal injury or  
property damage.  
ELECTRIC SHOCK HAZARD. Disconnect all power  
before installing or servicing heater. Failure to do  
so could result in personal injury or property dam-  
age. Heater must be installed or serviced by a  
qualified person in accordance with the National  
Electrical Code. NFPA 70.  
This design has the versatility of field adjustments of voltage  
kW through various wiring combinations.  
The NWHSRG model is a general purpose water circulation  
heater intended for indoor use. E2 designs have a Moisture  
Resistant/Explosion Resistant enclosure. Designs are up to 40kW  
- DO NOT USE THE NWHSRG MODEL FOR OIL.  
The NWHOSR model is a general-purpose regular and fuel oil  
solution circulation heater intended for use indoors. E2 designs  
have a Moisture Resistant/Explosion Resistant enclosure. Designs  
are up to 10kW - DO NOT USE THE NWHOSR MODEL FOR  
WATER. Ensure the wiring guide for oil is used for the correct  
wiring diagram.  
The system designer is responsible for the safety  
of this equipment and should install adequate  
back-up controls and safety devices with their  
electric heating equipment. Where the conse-  
quences of failure could result in personal injury or  
property damage, back-up controls are essential.  
Both the NWHSRG and NWHOSR use six INCOLOY® sheath  
elements welded to a steel 2.5” screw plug. The vessel is cast iron  
and is surrounded by 1.5” insulation and a sheet metal jacket. For  
water applications, the vessel has a galvanized coating. A J-type  
thermocouple in a thermowell is standard. These versaTHERMTM  
heaters are designed for 150 psig max. at 35°F min. to 300°F max.  
If foreign material is to be carried by the liquid flow, install  
suitable filters in the inlet pipe to the heater.  
Ensure the temperature/pressure is controlled below the vapor  
point of the liquid at all times and is within the temperature/pres-  
sure ratings for this heater.  
Heating elements must be completely immersed in liquid when  
energized.

1. Be sure line voltage matches your intended voltage and does  
not exceed the max voltage on the nameplate.  
2. Electric wiring to heater must be installed in accordance with  
local and National Electrical Codes by a qualified person as  
defined in the NEC.  
Note: Dotted lines indicate “customer furnished.” Complete power/temperature  
control panels or components are available. Contact Chromalox 1-800-443-2640  
for more information and assistance.  
3. Power controllers must be used with this product.  
4. Electrical wiring to heater should be with rigid conduit or flex-  
ible conduit to keep corrosive vapors and liquids out of the  
electrical enclosure. If high humidity is encountered, the con-  
duit should slope down away from the heater.  
5. Refer to appropriate wiring diagram for your model heater  
from the Wiring Guide (on next two pages).  
The specific Wiring Guide provides easy to follow steps to  
determine the appropriate wiring diagram for your heater instal-  
lation. Figure 1 may be referenced as a general diagram of how  
a contactor and temperature control are used in conjunction  
with the specific wiring diagrams.  
6. Use ground fault protection equipment where electrical insula-  
tion failure can cause process problems.  
7. When element wattages are not equal, heaters must not be con-  
nected in series.  
8. If flexible cord is employed, a watertight connector should be  
used for entry of the cord into the electrical enclosure. Outdoor  
applications require liquid-tight conduit and connectors.  
9. If application uses a standard PCN at different voltages and  
kWs from the Wiring Guide, refer to the Customer Wiring  
Guide Supplement if included with these instructions, or con-  
tact Customer Service at (800) 368-2493.

WIRING GUIDE – OIL (NWHOSR)  
Directions:  
Step 1: Select the PCN number below which matches the PCN number on your heater.  
Step 2: Choose your kW, Volts, phase, and number of circuits under your PCN number (you must know the kW and watt density  
(watts/sq. in.) needs for your application).  
Step 3: Note the Wiring diagram # for your selection.  
Step 4: Go to Wiring Diagram sheet. Peel off the diagram that matches the # in step 3. Stick this to the inside of your electrical enclosure.*  
Step 5: Peel off corresponding Volts, circuit-phase, and kW info from the Wiring Diagram sheet and stick to the designated spot on the  
nameplate. (These labels will cover the maximum rating stamped on the nameplate.)**  
Step 6: Wire Heater according to the sticker on the inside of your electrical enclosure (from step 4).

PRE-OPERATION  
1. Follow the instructions for operation of your application.  
Ensure your procedure includes:  
A. Make sure all electrical and piping connections are tight.  
B. Remove all air from the heater and piping.  
OPERATION  
Important: NWHOSR/NWHSRG Circulation Heaters  
If the heater is not properly submerged, the heat-  
ing elements will overheat and could result in a fire  
or damaged equipment.  
®
are equipped with INCOLOY heating elements and  
cast iron heating chambers (galvanized for the  
NWHSRG). It is the responsibility of the purchaser of  
the heater to know the chemical composition of the  
corrosive solution and the character of the materi-  
als entering the solution as well as the corrosive  
effect of the solution upon the heating elements  
and chamber.  
1. Do not heat solutions that are corrosive to the heating element  
sheath or the heating chamber.  
2. Terminal ends of heater must be protected from drippings, con-  
densation, spray or direct spill-over of material. Their presence  
at the terminals may damage heater electrical insulation.  
3. If foreign material is carried by the liquid flow, install suitable  
filters in the inlet pipeline to the heater. Liquid flow to the  
heater should be free of suspended solids.  
Sheath corrosion can result in a ground fault which  
depending upon the solution being heated, can  
cause an explosion or fire.  
4. Do not allow heater to operate when liquid flow is interrupted.  
5. The NWHSRG/NWHOSR is designed as a flow through  
heater. The chamber must be full for safe operation.  
MAINTENANCE  
Note: User is responsible for maintenance schedule based on  
their knowledge of the heated medium and operating conditions.  
3. Periodically check temperature control operation to insure  
accurate and safe process operation.  
ELECTRIC SHOCK HAZARD. Disconnect all power  
before servicing heater. Failure to do so could  
result in personal injury or property damage.  
Heater must be serviced by a qualified person in  
accordance with the National Electrical Code.  
NFPA 70.  
4. Check all electrical connections periodically and retighten con-  
nections which may have loosened in service. Replace wire  
and wire terminals which show signs of oxidation which would  
interfere with establishment of reliable electrical connections.  
5. Correct any excessive leaking. Also refer to the last step in the  
installation section regarding adequate collection/drainage.  
6. Reinstallation steps.  
1. Remove heating element assembly periodically to check heater  
sheath for sealing, corrosion or excessive oxidation. Correct  
operating conditions to minimize sheath deterioration. Refer to  
warnings in operation section.  
A. Reseal thread fittings with adequate seal material for the  
pressure/temperature rating on your heater.  
B. Refer to the pre-operation section.  
2. Drain heater periodically to remove sludge deposit. Deposits  
can act as an insulator and shorten heater life.
