installing heater. Sludge must not touch the corrugated heating
surface of the immersion unit.
6. Check point of tank suction to make sure it is 12” or more off bot-
tom of tank. This will insure a minimum liquid level of 12” and
prevent heater from being uncovered while in operation. The
heater must not be energized unless it is completely submerged.
7. Machine manhole cover per Figure B or install optional terminal
housing manhole adapter to manhole cover or storage tank per
Figure C. All welds must be liquid tight.
DANGER: Hazard of Fire. If adapter is to be welded directly into
tank, remove flammable liquids, and vent all combustible gases or
vapors from storage tank before performing welding operations.
2. Remove any obstructions which may interfere with proper instal-
lation of heater into tank.
3. Clean manhole area to eliminate dirt and water which can be
picked up by heater during its insertion into tank.
4. Time the installation so oil level in tank is half full or less. This
will greatly facilitate insertion and positioning of heater.
5. Check sludge in bottom of tank to ensure it does not interfere with
operation of heater. Standard FXTH heaters are supplied with 4”
sludge legs. Sludge in excess of 3” must be removed before
INSTALLATION OF HEATER ASSEMBLY IN TANK
1. If tank is type with manhole located near end of tank rather than
in center, install a temporary pulling cable at far end of tank
through any available port such as (l) fill pipe, (2) suction port, (3)
auxiliary manhole, etc., and thread the cable through the tank and
out the manhole to be used for installing the heater. The pulling
cable will be used to pull front lifting cable through auxiliary port
and then pulling cable is disconnected. See Figure D.
Figure D
2. Align heater assembly along centerline of tank having rear end
(riser end) of assembly farthest from manhole. Note: On tanks
with manhole near end rather than in center heater assembly
should be placed on side of manhole farthest from end of tank.
See Figure E.
3. Tie the riser(s) with rope or suitable line at a point just below the
union on riser(s). Anchor rope to any convenient nearby anchor-
ing point. Length of rope should be sufficient to allow riser(s) to
be inserted into tank just inside manhole but not below oil level.
CAUTION: If oil gets into riser, it will cause failure of the heat-
ing element.
Figure E
4. Carefully turn heater over, feet upward, taking care it is flexed in
only the one plane. (See Figure F.) Support must be maintained on
riser end of heater to avoid overstressing riser(s) until heater is
lowered into tank.

the above procedure, or in above ground tanks, ask for Factory rec-
ommendations for installation of heater.
(end manhole) or Figure H, Step 4 thru 7 (center manhole). Once
the heater has touched bottom, use pulling wire (front lifting
cable) to pull heater toward far end of tank.
6. Before lowering back end of heater, visually gage the remaining
length of heater to be laid down, to be certain an equal amount of
clearance is allowed at both ends of tank. Back end of heater is
lowered into place using rear lifting cable. CAUTION: NEVER
USE RISERS TO SUPPORT HEATER TUBES.
Step 4
7. Where additional heater assemblies are to be installed in the same
manhole, follow same procedure, being careful not to interfere
with risers or cable on the initial heater.

INSTALLATION OF FXTH TERMINAL HOUSING
A. Position manhole cover adjacent to manhole. Very carefully untie
rope from anchoring point and pass it through (1) manhole gasket,
(2) opening in manhole cover, and (3) terminal housing gasket.
Securely refasten rope to anchoring point. Do not allow riser
end(s) to fall into oil, or permanent damage will result to the
heater. Bolt down manhole cover using a suitable gasket sealant if
required to obtain water-tight seal.
B. Pull riser(s) upward into position next to terminal housing. Wrap
teflon tape on threaded riser connections and fasten into underside
of terminal housing. Unused connections on bottom of housing
will already contain flush plugs. Attach lifting cables to ring on
under side of terminal housing.
C. Bolt terminal housing to manhole cover or manhole cover
adapter, again using suitable gasket cement. If manhole cover is
machined per Figure B, be sure to install copper gasket washers
under bolt heads. Position housing so conduit connections are in
the most convenient position for your particular installation.
Connect all riser leads to terminals, following markers on wires
and terminals referring to wiring diagram Figure J.
D. Install power leads from terminal housing to control center. See
Specifications Table, Page I for amperages to determine wire and
conduit size as determined by the National Electric Code.
E. To install thermostat wells, insert closed end of the well into brass
fitting in bottom of terminal housing. Push well completely to
bottom of tank. A preliminary measurement from manhole level
to tank bottom will aid proper insertion. The well may first hit the
heater. It is then necessary to manipulate the well so that it will
glance off the rounded heater surface and extend to tank bottom.
Mark side of tube at the swage fitting and then pun upward sev-
eral feet to working level. Using a tube cutter, cut the tube at a
point exactly 7” below the mark. Once the tube is cut, be extreme-
ly careful the tube is not allowed to drop through fitting and into
tank. Partially tighten fitting so this cannot happen. Position the
upper end of well 5” off top of tube fitting, then firmly tighten the
fitting. Insert bushing (located in shipping bag inside of terminal
housing) into top of well. This will prevent burrs on tube from
cutting the bulb or capillary of thermostat. Repeat this procedure
until all wells are installed. There can be as many as three wells;
(1) Thermostat, (2) Temperature Indicator, (3) Low Limit Alarm.
F. Install thermostat mounting plate. Make sure thermowells are
aligned with openings in plate and over-temperature leads from
riser are brought through plate. Fasten plate into position.

INSTALLATION OF HEATER ASSEMBLY IN TANK (cont’d.)
G. Carefully unwind and straighten thermostat capillary tube. The
I. If temperature indicator is employed, wire in accordance with
Figure J. Use wire size as recommended for connecting to control
center.
capillary must be reasonably straight. Be absolutely certain the
bulb is seated at bottom of well. Carefully coil any excess capil-
lary and position next to thermostat and away from electrical con-
nections. Repeat same procedure if low limit alarm is provided.
Attach wire for overtemperature sensor to terminals.
J. Install control wiring through 3/4" conduit connection as indicat-
ed on page 1. Leave lid off' terminal housing until operational
check is completed. Install breather tube on the outside of the ter-
minal box as shown on page 1, Make sure top of tube is at least
12" above the drainage water level. CAUTION: All conduit con-
nections to terminal housing must be sealed to prevent entry of
any water, water vapor or condensation into terminal housing.
Breather tube length may be cut to shorten height, or extended for
higher flood levels by using 3/8” compression tube coupling and
3/8” tubing, as desired between formed breather tube and elbow
fitting on side of terminal housing.
NOTE: Over-temperature control is located in the Chromalox
Control Center. If heater is supplied without control center, be
sure to obtain an over-temperature control for a positive thermis-
tor, otherwise heater will be without over-temperature protection.
H. If the low temperature thermostat is being used, connect annunci-
ator leads directly to terminals on this thermostat and provide an
independent power source. The switch rating is; 20 amp @ 115V,
15 amp @ 230V, pilot duty 125VA.

H. If any difficulties are encountered during the installation and
check-out, call your local Chromalox Representative or
Chromalox Product Service.
INSTALLATION OF REMOTE CONTROL CENTER
CAUTION: Hazard of electric shock. Any installation involving
electric must be grounded to earth to eliminate shock hazard.
1. A safe maximum temperature limit on control cabinet compo-
nents is 125°F. Choose a mounting location not in direct sunlight
or exposed to any other source of excessive heat. If the panel must
be mounted in direct sun, a sun shield must be employed.
2. Install proper control and power wiring to control center as per
Figure J. Power lines are to be sized for the particular heater load.
Double check to insure proper grounding procedures have been
followed for heaters and control panel.
3. Available inside control panel are connections A and A1 which
provide for an over-temperature alarm; such as, horn, bell, etc., to
be mounted remotely as required. These terminals are rated at
50VA, 120V.

5. Secure control box door, then place circuit breaker in “on”
position and energize heater with panel switch. Start with
45 second time interval and increase until a definite rise in
temperature on each heater tube can be felt with the bare
hand. NOTE: Adjustable time delay(s) in multi-stage units
have been preset at factory to provide steps for energizing
individual circuits.
6. Observe green light (which indicates “power”) when clos-
ing circuit breaker, first amber light with panel switch "on"

OPTIONAL EQUIPMENT
Temperature Indicators (Suffix “D”)
(FXTH Heater Assembly and Control Center will have
suffix "D" e.g. FXTH-11206D, WCG15-213D)
It is very important the resistor wire be properly soldered after
adjusting.
MOUNTING
NOTE: When Thermocouples with external resistance higher than 10
ohms will be used, a special pyrometer will be required. The use of
other than thermocouple wire for leads or extensions may result in
improper ambient compensation.
Temperature indicators are balanced for accurate reading in a normal
vertical position unless specified otherwise. All pyrometers labeled
"shielded meter" may be used in any type of panel with little or no
effect on calibration. Those labeled "non-magnetic" must be used
only on aluminum, plastic, wood or other non-magnetic panels. They
will read low if mounted in a steel panel. Pyrometers which are
labeled "magnetic" are intended for installation on steel panels. A
steel compensating ring is normally supplied where panel material is
not specified. Discard the ring when mounting on a steel panel. If the
pyrometer is used on a non-magnetic panel, the steel ring must be
used. Be sure the slit in the ring is at the top of the meter barrel and
the ring is pushed as far forward as it will go.
ABBREVIATED TABLE OF THERMOCOUPLE RESISTANCE
The table lists the resistance in ohms per pair-foot for various types
of commonly used thermocouples for a number of different gauges of
wire. By using this table, it is necessary only to measure the length of
the thermocouple, knowing the type and gauge, to determine its
approximate resistance. (Actual measurement of the thermocouple
resistance is preferred to using the table.)
Ohms Per Pair - Foot
THERMOCOUPLE SELECTION AND CALIBRATION
Each pyrometer is marked on the dial with the type of thermocouple
and the total external resistance for which it is calibrated. Use of any
other type of thermocouple or one with a higher resistance than
marked will result in incorrect readings. (Type J thermocouples are
normally used.) All standard pyrometers are calibrated for 10 ohms
external thermocouple resistance and are provided with a 10 ohm cal-
ibrating resistor bobbin. (Non-standard pyrometers are usually cali-
brated for the specific external resistance ordered and no resistor bob-
bin is supplied.) This resistor bobbin must be adjusted so the total
resistance of the thermocouple and the bobbin add up to 10 ohms in
order to maintain calibration accuracy. Therefore, for a 5 foot, 20
gauge, iron-constantan thermocouple, the resistance of the thermo-
couple would be approximately 1.75 ohms and this resistance must be
subtracted from the calibrating bobbin. Each turn of the wire on the
resistor bobbin represents 0.5 ohms and for this example, 3-1/2 turns
would be removed. The total resistance of the thermocouple plus the
resistor bobbin would then add up to 10 ohms. For other values of
thermocouple resistance, simply remove more or less turns to adjust
for the total value of external resistance marked on the pyrometer
dial.

CHROMALOX TYPE TMC 7-DAY TIMER
TMC 7-day Calendar, Electric Dial Timer is used to provide auto-
matic start-up/off-on control of large tank heaters or could be set up
for non-peak operation. Standard features: 7-day calendar dial per-
mits different on/off schedules on different days of week. 2 to 14
replaceable trippers for up to 4 on/off operations per day, up to 28
on/off operations per week. 3 hour minimum on or off time; 21 hour
maximum on or off time. Independent 4-pole design allows SPST,
DPST, SPDT, switching. Manual on/off lever transfers switch opera-
tion without disturbing daily or weekly preset schedule. Heavy duty
synchronous motor suitable for operation between -40°F and +140°F.
Switch slider bar assures positive switching. Heavy duty terminals
accommodate up to AWG No.8 wire.
CAUTION: To set the correct day and time at beginning of initial
start-up, ROTATE THE PROGRAM CLOCK DIAL CLOCKWISE
ONLY. DO NOT ATTEMPT TO TURN POINTER!
Adjusting and Maintenance of Time Switch:
1. Periodically check trippers to insure that they are tightly fastened
to Program Clock dial. CAUTION: TIGHTEN TRIPPERS WITH
FINGERS ONLY!
2. Rotate Program Clock dial CLOCKWISE one hour in Spring to
adjust for daylight saving time (in areas where required). In Fall,
carefully rotate clock dial CLOCKWISE approximately one full
turn to reset at correct day and time for standard time. Check all
trippers to insure they have not moved during rotation.
3. The Program Clock motor is permanently lubricated. Lubrication
of other parts is not required.
OPERATION
“Off” Setting - de-energizes the entire zone control circuit, thus de-
energizing all heating-cooling equipment in the zone. This setting can
be used for extended summer shutdowns, etc.
4. The Program Clock switch contacts are factory set and need no
field adjustment.
“Automatic” Setting - allows the Day-Night Clock Panel to cycle
the control system according to the program clock dial tripper set-
tings.
