5. PRE-INSTALLATION SURVEY
The SEM(U) / IT(U) heating system must
have gas piping of the correct diameter,
length, and arrangement to function properly.
Carefully survey area to be heated, and for
best results, whenever possible, place burner
and combustion chamber in coldest area.
For this reason, a layout drawing is necessary.
6. MOUNTING CLEARANCES
This heater must be mounted and positioned
to maintain the minimum clearance to combustible materials as shown in FIGURE 1
(PAGE 6) TABLE 3 (PAGE 6). For recommended heater placement refer to TABLE 2
(below). Heaters should also be located and
installed with respect to building construction
and equipment to provide a minimum clear-
ance of 24 inches from the end of burner
housing for servicing and cleaning of burner,
blower and controls. A minimum horizontal
clearance of 4 ft. from electrical meters, gas
meters, regulators and relief equipment is re-
quired by ANSI Z223.1.& CSA B149.1-00.

8. SUSPENSION SYSTEM
The system configuration and available
support locations must be considered in order
to locate the radiant tubes correctly. Labour
and material can be reduced by locating
(system configuration permitting) directly
under structural members such as joists, steel
or wood beams, etc.
Chain is recommended for hanging the tube
system, connecting the hangers to beam
support as illustrated in FIGURE 3 (below).
To support burner and keep it level, a
separate suspension chain must be attached
to the eye hook at flange end of burner angled
slightly back over burner, FIGURE 4
(below). This will permit normal expansion
and contraction of the tube system. (If rigid
devices such as rods are used in place of
chain, swing joints or other means of
sufficient length must be provided to
compensate for expansion.)

9. BURNER AND TUBE INSTALLATION
With all hangers suspended at the same
height, insert first aluminized tube section,
through 4" hole into first two wire hangers.
Bolt burner to flange on first tube section,
SEE FIGURE 6 (page 9). Subsequent lengths
of tube can then be installed, by joining them
together one inside the other and locking the
joints using the aluminized steel clamp. SEE
FIGURE 7 (page 9). Models SEM(U) / IT(U)
200 & 175 have alumatherm as the first section with a welded Flange, the second section
is aluminized, and subsequent lengths are
steel painted.
Slacken the bolts and slip the coupler over
Page 9
the end of the pipe to be joined, making sure
the swaged end of the tube is fully inserted
into the plain end of the tube before repositioning the coupler. The coupler should
then be centred across the joint before tightening up.
If a turbulator is necessary it will be factory
installed into the tube(s). The tube(s) will be
marked stating where it must be installed in
the system, see TABLE 4 (page 12) for the
models which do require turbulators.
Note: Turbulators are ALWAYS
installed at the vent end of the heater .

10. REFLECTOR INSTALLATION
After burner and tubes have been installed,
slide the focus shield reflectors one at a time
into the wire hangers. As each successive
focus shield reflector is installed on an in-line
installation, the ends of the focus shield
reflectors will overlap to provide continuous
coverage over the entire tube system. The
overlapping joints MUST BE FASTENED
together.
Note that for both horizontal and angle
mounting, the tube must be level. Improper
mounting can result in overheating of
controls and combustible materials. Use only
non-combustible mounting hardware.
Side reflectors can be added to the heaters as
an option. They should be secured directly to
the focus shield reflector using "S" hooks or
chain. Drill three holes into the focus shield
reflector flange along side, matching up with
three holes already in side reflector. Mount
side reflector as close as possible to the focus
shield reflector.

A length of ‘C’ Vent is to be installed on the
swaged end of the last tube before any Elbow
or Vent Cap is fitted. When the heater is installed and indirectly vented, it is required in
Canada that the heater be electrically interlocked to an independent exhaust fan by
means of an Air Proving Switch. The exhaust
fan must be sized to create 3CFM for every
1000 Btu/hr or fraction thereof, of total input
of installed equipment. Consult CSA.B149.100 latest edition for requirements.
DIRECT VENTED APPLICATION
A length of ‘C’ Vent is to be installed on the
swaged end of the last tube before any Elbow
is fitted. All venting must be single wall "C"
vent except that portion of vent passing
through a combustible wall or roof then type
"B" vent may be used as per CSA's interim
requirement. When venting horizontally, the
flue vent system must slope downwards approximately 1/4" per foot toward the vent terminal, starting at the termination of the radiant tube. For horizontal through the wall

venting, the approved 4" or 6" horizontal wall
vent terminal should be used and mounted
18" from the outside wall to the inside edge
of terminal opening. The flue vent terminal
used must be of the approved type supplied
by the manufacturer or by an approved "B"
vent manufacturer. It is the responsibility of
the installer to be familiar with current local
codes or ANSI Z223.1 / CSA.B149.1-00 latest editions for all venting requirements, and
practices.

The heater is designed to operate with single
wall 4” diameter 26 gauge minimum exhaust
vent.
When venting horizontally, the flue vent system should slope downwards approximately
1/4" per foot toward the vent terminal, start-
ing at the termination of the radiant tube.
When vent and combustion air are taken
through the roof, the exhaust vent should always terminate higher than the combustion
air intake, to prevent recycling the products
of combustion back into the heater.
The total maximum allowable combined
length of vent and combustion air duct is 80'
for SEM / IT 200, 175, 155 and 130, and 50'
for SEM / IT 110, 80, 60 and 45. Total maximum allowable combined vent and duct is
reduced by ten feet for every 90o elbow installed in the vent or duct. Should the tube
system be installed with a 90o elbow in the
radiant tube, 10 ft must be deducted from the
length of vent and duct. Should the tube system be installed with a 180o elbow or an SEM
(U) / IT(U) turn box in the radiant tube, 20 ft
must be deducted from the length of vent and
duct. Neither the individual flue vent nor the
combustion air duct is to exceed 50 ft in
length. Exceeding the allowable lengths may
create condensation problems and will void
CSA Design Certification. The horizontal
flue vent shall not terminate less than the following guidelines except where indicated in
brackets:
• One feet above grade level, unless its lo-
cation is adjacent to public walkways,
then it has to be not less than seven feet.
• Must be installed to prevent blockage by
snow and protect building materials from
Page 14
degradation by flue gases.
• Directly below a soffit or over- hang.
• Directly above a gas utility meter or ser-
vice regulator.
• Twelve inches from combustion air inlet
of any heater with input up to 100,000
Btu/hr.
• Three feet from combustion air inlet of
any heater over 100,000 BTU.
• Within six feet of a mechanical air supply
inlet to any building.
• Twelve inches from sides and bottom and
eighteen inches from top when installed
close to the corner of a building.
• All vent pipe with a slip fit connection
must be mechanically secured. A length
of ‘C’ Vent is to be installed on the
swaged end of the last tube before any
Tee is fitted.
• As an Option, two heaters may be vented
through an approved common 4"x4"x6"
Vent Tee, supplied by the manufacturer.
The two heaters must then be controlled
by a single common thermostat or “ON/
OFF” switch.

Where the vent pipe passes through areas
where the ambient temperature is likely to
produce condensation of the flue gases, the
vent pipe shall be insulated with a suitable
material as approved and specified by the insulation manufacturer.

FLUE VENT END
OF TUBE
For Direct and Indirect Venting it is recommended to install a length of ’C’ Vent onto the
end of the last tube before any fittings are installed. The “C” Vent connection should be
slipped onto the tube and positioned approx 6” beyond the swaged portion of the 4” tube
and must be secured with sheet metal screws.
12. COMBUSTION AIR DUCT
Where heater is operated in a negative air
condition or in contaminated air atmosphere
such as woodworking shops, air for combustion must be ducted from outside to intake
flange on blower. The total maximum combined length of vent and combustion air duct
130, and 50' for SEM(U) / IT(U) 110, 80, 60
and 45. Neither the individual flue vent or
combustion air duct is to exceed 50'. The total maximum allowable combined vent /air

Do not install filters on the combustion air
intake.
For ease of installation, this heater has an optional fresh air intake duct hood. It can be
used as an outdoor intake hood to bring combustion air to the heater from outside. If
drawing in fresh air from outside, it is recommended as per common Engineering practice,
that any single wall pipe exposed to cold air
must be insulated to prevent condensation. If
heater is being vented horizontally through
Minimum air intake inlet distances:
the wall and combustion air is ducted in from
outside to the Burner, it is advisable to create
a trap at the Burner. The trap is created by
dropping the pipe below the level of the tube
(much like a plumbing trap using elbows or a
flexible connector) before connecting it to the
fresh air intake on top of the Burner box, Do
not use flexible dryer hose for air inlet duct,
the corrugated sides of this tubing add too
much restriction to the air flow. A good quality industry approved insulated flex is allowed.

heaters with input up to 100,000 Btu’s/hr.
CAUTION:
In installations where chlorinated Hydrocarbons are in use, such as Trichloroethylene or
Chloroethylene Nu it is essential that combustion air be brought in from
non-contaminated areas. Burning the fumes from these gases will create Hydrochloric
acid fumes, which are detrimental to humans, equipment and buildings. Typical sources
of other contaminants are paint removers, paints, refrigerants, solvents, adhesives,
degreasers, lubricants, pesticides, etc.
13. GAS SUPPLY INSTALLATION
It is recommended that a locally approved
flexible connector supplied by the distributor,
be installed between the heater and gas piping. The heater must be isolated from the gas
supply piping system by closing its individual
manual shut off valve (supplied by installer)
during any pressure testing of the gas supply
piping system.
CAUTION:
If a rigid gas pipe connection is made, then compensation for normal gas
supply pipe expansion, and radiant tube expansion must be provided. All
piping must conform to local codes.

KH
DO NOT use pressures greater than 1/2 psig.
to pressure check the heater.
TEST FOR LEAKS: All gas piping and
connections must be tested for leaks after the
installation is completed.
Apply soap suds solution to all connections
and joints and if bubbles appear, leaks have
been detected and must be corrected. DO
NOT USE A MATCH OR OPEN FLAME
OF ANY KIND TO TEST FOR LEAKS.
NEVER OPERATE THE HEATER WITH
LEAKING CONNECTIONS.
The supply system should be checked first
with heater turned "OFF" followed by another
check with heater turned "ON".
IMPORTANT:
The minimum supply-line pressure at the
inlet to the heater regulator must not, in
any instance, be lower than 5.5 inches of
water column pressure for natural gas and
11.0 inches of water column pressure for
propane gas. The supply line gas pressure
must be checked with all the heater (s) operating.
Installation of a gas line (trap) “drip leg"
is required at the inlet connection tee following the pipe drop to the heater. Failure
to provide a “drip leg” could result in condensation and foreign matter passing into
the gas valve. Failure to install a “drip leg”
in the gas line will void the warranty.

14. HEATER EXPANSION
Due to the characteristics of tube heaters, the
installer must allow for 1” expansion for
every 10’ length of tube. In order to address
this characteristic, it is suggested that the
gas line, flue vent, and combustion air
intake (if used) be installed in such a manner,
that normal expansion of the heater will be
accommodated.

15. ELECTRICAL AND THERMOSTAT WIRING
(SEE WIRING DIAGRAMS PAGE 22)
Wiring must be done in accordance with
local codes. The total load of all heaters must
be considered in determining the required
Each individual tube heater requires 120
Volts 60 Hz electrical power sized for
145VA. The heater can be controlled by
a line voltage thermostat or "ON/OFF"
switch.
IMPORTANT:
Do not install the thermostat in the direct
radiant stream.
The voltage at the spark ignition control
is 110V. Note that proper functioning
of the heater will be adversely affected if
the input voltage varies by more than +/10%
contact rating of the controlling thermostat
or switch.
WARNING:
The heater must be electrically grounded
in accordance with the current Electrical
Code.
It is good wiring practice and the installers
responsibility to ensure that correct wiring
polarity is maintained throughout installation.
The Fenwal DSI control is polarity sensitive
and WILL malfunction if the polarities are
reversed. The black wire MUST be wired to
Hot, and the white wire MUST be wired to
Neutral. If the polarity is reversed the module
will not function correctly and will eventually
burn out.
16. HIGH ALTITUDE INSTALLATIONS
Canada: All of the SEM(U) / IT(U ) radiant
tube heaters are approved for altitudes zero
to 4500 feet above sea level and do not require de-rating.
USA: If a heater is to be installed at altitudes above 2000 ft, the input must be reduced by 4% per 1000 ft. If your local utility de-rates the heat content in the gas supply, no modification of the heater is required. If the gas supply is not de-rated, the
orifice must be changed according to the
chart on page 31. Check with your local
utility regarding de-rating of this appliance.

17. SEQUENCE OF OPERATION / FLAME RECOVERY/ SAFETY LOCKOUT
Start up - Heat Mode
When the thermostat is set above the ambient
temperature, 120 VAC is supplied to the L1
terminal. When this occurs the control
will power up and perform a self-check routine and begin a prepurge*, if selected. Following the pre-purge, the gas valve is energized and sparks commence until flame is detected or the Trial For Ignition (TFI) period
expires.
When flame is detected, the spark is shut off
and the gas valve remains energized. The
thermostat and burner flame are constantly
monitored to ensure that the system is functioning properly. When the thermostat is satisfied and the demand for heat ends, the gas
valve is de-energized immediately and the
flame is extinguished.
Flame Failure During TFI Period
Should the burner fail to light or flame is not
detected during the first trial for ignition period, the gas valve is de-energized and the
control starts the inter-purge sequence before
another ignition attempt. After inter-purge,
the control will attempt two additional ignition trials. If these attempts are unsuccessful
the control will go into lockout mode.
Flame Failure of Established Flame
Re -Ignition
If the established flame signal is lost while
the burner is operating, the control responds
and begins sparking within 0.8 seconds. The
spark will be energized for the duration of the
trial-for-ignition period in an attempt to relight the burner. If flame is re-established,
normal operation resumes.
If the Burner does not light after the first attempt, the inter-purge sequence is completed
between attempts to re-light the burner. If the
burner fails to light after the
third try, the control will de-energize the gas
valve and go into lockout mode. See
Lockout Recovery
Lockout Mode (On-Board Safety System)
After single or multiple attempts to light the
burner have failed or flame is not established,
the control automatically enters lockout The
control will not open the gas valve unless
there is intervention by the user. See Lockout
Recovery.
Lockout Recovery
For lockout recovery, reset the thermostat
below ambient temperature or remove the
120 VAC power supply for 5 seconds

18. LIGHTING INSTRUCTIONS
LIGHTING SEQUENCE:
Refer to the lighting instructions on the outside cover of the burner housing. Again, if
the unit goes off on safety, main power to the
unit must be manually interrupted for a 30
second reset period before the heater can be
restarted.
NOTE:
On initial installation, the unit may lock
out on safety owing to the length of time
required to bleed air from the gas piping
system.
19. RECOMMENDED MAINTENANCE
1. Inspect the venting system each heating
season and repair or replace worn parts
as required.
2. Check the inlet air opening and the
blower periodically, cleaning off any lint
or foreign matter, as it is important that
the flow of combustion and ventilation
• Rotate gas valve knob to ON position.
• Set Thermostat to the desired setting.
• Turn Power ON to heater.
• This should start the Blower, sending the
DSI Control into its pre-purge cycle, then
into ignition, and light off.
• If heater fails to light, shut down heater
and wait 5 minutes before relighting it
• To shut down the heater just reverse the
previous steps..
must not be obtructed. In addition we
recommend the entire system be checked
once a year by a qualified service techni
cian.
3. Lubricate Blower motor, by adding sev
eral drops of oil to oil ports located on
the left hand side of the motor.

22. SPARK IGNITION CIRCUIT
The step-up transformer in the ignition control provides spark ignition at 30,000 volts (open
circuit). To check the spark ignition circuit, proceed as follows.
1 Shut off gas supply to the gas control
2 Disconnect the ignition cable at the ignition control stud terminal to isolate the circuit from
the spark igniter or igniter/sensor
3 Prepare a short jumper lead, using heavily insulated wire such as ignition cable
CAUTION
In the next step, DO NOT allow fingers to touch either the stripped
end of the jumper or the stud terminal. This is a very high voltage circuit and
electrical shock can result.
1 Perform this test immediately upon energizing the system before the ignition control goes
into safety lockout and interrupts the spark circuit. Touch one end of the jumper firmly to
the ignition control GND terminal. (DO NOT remove the existing ground lead.) Slowly
move the other end of the jumper wire toward the stud terminal on the ignition control to
establish a spark.
2 Pull the wire away from the stud and note the length of gap at which spark discontinues.
3 A spark length of 1/8 in. (3mm) or more indicates satisfactory voltage output. If no arc can
be established, or the maximum spark is less than 1/8 in. (3mm), and power to the ignition
control input terminals was proved, replace the ignition control.
SPARK IGNITER SET UP
Please use the following diagram for checking
the Igniter gap.
If the gap is incorrect all adjustments should
be made with the GROUND PRONG/PIN
ONLY!
DO NOT BEND THE IGNITER
PRONG!!!!
The black bars located at the lower right corner can be used as a guide for adjustment.
