INSTALLATION
1. LOCATION: This machine should be
installed by only qualified technicians. The
machine should be set upon a level surface
where it will not be affected by strong winds,
rain, snow, extreme heat, and freezing
temperatures. Install the machine
considering locations for chemical pick-up, fuel
connections, electrical connections, water
hook-up, venting, and maintenance.
All wiring and electrical connections should
comply with the National Electrical Code (NEC)
and with local codes and practices. Use the
chart on the next page for your cord selection
2. ELECTRICAL: Connect machine to an
electrically grounded circuit that is fused or
circuit breaker protected. The circuit must
match that specified in the ELECTRICAL
section under MODEL SPECIFICATION
3. EXTENSION CORD: The use of an extension
cord that has undersize wire compared to the
amp draw of your machine will adversely limit
the starting load carrying abilities of the motor
and machines performance. Use only 3-wire
extension cords that have 3-prong plugs and
3-pole cord connectors that accept the plug
from the product. Use only extension cords
that are intended for outdoor use. These
extension cords are identified by a marking
“Acceptable for use with outdoor appliances;
store indoors while not in use.” Use only
extension cords having an electrical rating not
less than the rating of the product. Do not
use damaged extension cords. Use an
extension cord in good repair free of frays or
cracks in the outer covering. Do not abuse
extension cord and do not yank on any cord to
disconnect. Keep cord away from heat and
sharp edges. Always disconnect the extension
cord from the receptacle before disconnecting
the product from the extension cord.
WARNING: To reduce the risk of
electrocution, keep all connections dry and off
the ground. Do not touch plug with wet hands.
CHART FIGURES ARE BASED ON NOT
MORE THAN 100 FOOT
(Based on Ambient Temperature of 86°F (30°C)).
*Use Amp Draw indicated the same or higher than
your machine output
EXAMPLE: Machine Amp Draw 51, use 55 (2
Conductor). The thermostat type of cord shall be
C, PD, E, EO, EN, S, SO, SRD, SJ, SJO, SV, SVO,
SP.
The thermoset plastic types shall be ET, ETT,
ETLB, ETP, ST, STO, SRDT, SJT, SJTO, SVT,
SVTO, and SPT.
WARNING: CARBON

HAZARD
4. VENTING: This machine emits carbon
monoxide, a deadly gas, and must be vented if
used in an enclosed area. Improper venting
can cause poor combustion, delayed ignition,
down drafts, and the possibility of freezing the
coil. Contact your distributor or local heating
and air conditioning dealer for proper
materials. Local codes must be observed.

water inlet pressure specified in the GENERAL
section of the MODEL SPECIFICATIONS.
6. BARRIER: We recommend a barrier be installed
between the machine and wash area to prevent
moisture from coming in direct contact with
electrical controls, motors and transformers.
This will increase the machine’s life and lessen
electrical problems.
7. WATER CONDITIONS: Local water conditions
affect the coil adversely more than any other
element. In areas where troublesome
conditions may exist with like equipment (such
as water heaters), we recommend the use of a
water softener.
8. FREEZING: This machine must be protected
from freezing according to STORAGE section
of MACHINE MAINTENANCE.
9. COLD WEATHER: As the weather becomes
colder, fuel becomes thicker and may become
so viscous that the fuel will not flow properly.
As viscosity increases, the thicker oil can cause
delayed ignition, poor spray patterns, and
rumbling fires. As moisture will quickly
destroy fuel pumps, make certain that tank
openings are secure and moisture cannot
enter. In cold weather areas, frost build up
will occur in fuel tanks. As the weather warms
it turns to condensate, and the water will be
in the tank. Keep the tank clear of water, as
moisture reaching the fuel pump will cause
rust, and the pump will bind. A full fuel tank
will lessen condensation build up.
10. CHEMICALS: Mix chemicals per the chemical
manufacturers printed directions. Follow all
mixing, handling, application, and disposal
instructions. Wear gloves, boots, goggles, and
protective clothing appropriate for the chemical
being used
VENTING
WARNING: This machine emits carbon
monoxide, and deadly gas, and must be vented
if used in an enclosed area. Improper venting
can cause poor combustion, delayed ignition,
down drafts, and the possibility of freezing the
coil. Contact your distributor or
local heating and air conditioning
dealer for proper materials. Local
codes must be observed.
The information contained herein is offered for
reference only. You must comply with local
codes and investigate through your gas and
other utility companies when installing, as
there may be some special local requirements
you must comply with. Also see ANSI Z223.
1. DRAFT DIVERTERS: (STACKED CLEANERS)
Oil fired machines use a force air burner. The
oil burner can be influenced by “Natural Draft”
even though they have their own fan. A Bell
type draft diverter must be used here also.
THIS MACHINE IS NOT TO BE CONNECTED
TO A TYPE B GAS VENT.
NE PAS RACCORDER CET APPAREIL À UN
TUYAU D’ÉVACUATION DE GAZ DU TYPE B.
A. A draft diverter must be used on all
cleaners that are stacked. This includes
any chimney even if not expelled to the
outside.
B. Use a draft diverter of the inverted funnel
or bell type that meets all codes for
capacity and materials. Mount the draft
diverter directly to the stacking flange on
the machine
C. The draft diverter’s function is to insure
that the barometric pressures are as close
to the same as possible at the air inlet and
outlet to the coil and will not be changed
by either up drafts or down drafts.
D. Installation of a draft diverter WILL NOT
PREVENT THE COIL FROM FREEZING.
In areas where freezing temperatures are
common, some type of down draft
prevention must be used. Check local
08-08-03 Z08-11213CECN-02981 6

codes for acceptable methods for the
prevention of down drafts.
2. VENTING INSTALLATION INFORMATION:
A. Never Reduce the Stack size. The diverter
and stacking should be the same size as
the stack opening on the machine.B.
B. Straight Stacking through the roof
is preferred. Horizontal runs are not
desirable, but if necessary, be sure to pitch
the stack upward at a rate of two inches
per foot. When horizontal stacks are used,
vertical stacking must extend at least two
feet for every foot of horizontal stack.
C. Stack Extension above the roofline should
be sufficient to clear the peak of the roof.
(Refer to ANSI Z223.1 page 100 of
SPECIFICS)
D. A Rain Cap U.L. approved should be
installed on the stack

NOTE: Contact your local dealer for descaling of
your unit.
7. Disconnect the water supply.
8. Disconnect the electrical supply.
9. Reinstall the hose and gun assembly.
10. Remove the pressure gauge.
OIL BURNER CONTROLS
A. NORMAL CYCLE:
Turn cam to the burner position. The burner
should start and continue to run normally. (If
the burner starts, establishing flame, but then
locks out on safety, make "Flame Detector
Check" at this time.
B. SAFETY TIMING:
1. Let the burner run 5 minutes. Then remove one
of Flame Detector leads from "F" terminals.
After a time period corresponding to the safety,
stopping the burner.
2. Turn the cam switch to burner position.
3. Replace Flame Detector Lead removed step 1.
4. Wait 3 minutes. Then operate the manual reset
button on the front of control.
C. HIGH LIMIT AND THERMOSTAT CHECK:
1. Turn the cam switch to burner position.
2. Lower the setting of the high limit control to its
lowest setting. This setting should stop the
burner, unless the steam generator
temperature is below the minimum setting of
the high limit.
3. Return the high limit to it's proper setting.
Burner should restart.
4. With the burner running, turn thermostat to
it's lowest setting. This should stop the burner,
unless actual room temperature is below the
lowest setting of the thermostat. (Note: On
systems supplying domestic hot water, burner
will continue to run if low limit is not satisfied.)
5. Return thermostat to it's proper setting.
D. FLAME DETECTOR CHECK: (This test is not
required if control performs as described in
test A.)
08-08-03 Z08-11213G
ECN-02981 10

If the burner starts but the control locks out
(stopping the burner), check the flame detector
as follows:
1. Connect one end of the wire jumper to one of
the "F' terminals.
2. Turn the cam switch to burner position. As
soon as a flame has been established connect
other end of the wire jumper to the other "F"
terminal. WARNING: The control provides no
safety protection with the jumper installed. DO
NOT leave the burner in this condition except
for making this check. If the control still locks
out with the jumper installed, the control
should be replaced. If the control does not lock
out, however, check the operation of the flame
detector.
4. If safety lockout problem is of an intermittent
nature (only lockouts occasionally), the
following additional check may be made to
insure that the flame detector locations is not
a marginal one:
(a) Disconnect flame detector leads from "F"
terminals.
(B) Attach a jumper wire to one "F" terminal. Start
burner. Then immediately connect jumper wire
to the other "F" terminal. Burner should
continue to run.
(c) With burner running, attach flame detector
leads to an accurate ohmmeter. Reading of
ohm meter should also be acceptable,
Generally, though, the lower the reading, the
better the application, and less likely the
chance of a variation in the burner flame
causing a safety lock-out)
(d) If resistance of flame detector is over 1000
ohms, it may not be able to see the burner
flame properly . Check alignment of the flame
detectorthrough thehole inthe staticdisc. Clean
thishole if it is blocked by foreign matter. Check
for broken "F" wires.
(e) If flame detector alignment is a good but
resistance is still high, readjustment may be
necessary.
(f) WARNING: Be sure to remove wire jumper
after this flame detector check.
CHECKOUT PROCEDURE: Before leaving
installation, a complete operating cycle should
be observed to see that all components are
functioning properly. Limit switch function
should be tested to be sure the machine shuts
down when the limit contacts open.
HI LIMIT TEMPERATURE CONTROL
This control has been specifically designed to stop
heating equipment to prevent a dangerous
condition due to excessive temperatures.
A 240V neon pilot light (suitable for 120 to 240
VAC circuits) is included. It can be wired as
shown below to illuminate if the high limit trips
Switch Action:
It is the non-cycling manual reset
type of control which means
that if it's contacts open due
to the temperature exceeding
it's dial setting, the contacts
open, thereby stopping the heat
input to the machine.
MANUAL RESET BUTTON
Non-Cycling Manual Reset:
After this control has stopped the heat input to
the machine, it cannot be started unless some
authorized person pushes the reset button.
STEAM PRESSURE CONTROLS:
OPEN LOW MODELS: Contacts close high:
open low.
On open low models, range adjusting screw "A"
raises and lowers cut-in point (this also raises
or lowers cutout point by a like amount). Sat
cut-in point first with adjusting screw "B"
changes cutout point only. If control is
equipped with a lockout, contacts must be
reset by hand after opening.
