INSTALLATION INSTRUCTIONS
1. GENERAL
Installation of the STV-JZ Series gas-fired tube
heaters must conform to all Schwank heating installation design procedures including ventilation.
All local, provincial and national code requirements including the current latest edition B149.1
INSTALLATION CODE” in Canada, and ANSI
Z223.1 in the U.S.A. for gas burning appliances
and equipment. The latest edition Electrical Code
PART 1 CSA C22.1 in Canada and ANSI/NFPA
N0 70 in the U.S.A. must also be observed. Due
to ever changing standards and requirements, re-
vision to our equipment and installation procedures may be necessary. In case of discrepancies,
the latest installation manual will take priority.
The STV-JZ heater may be installed for heating of
non-residential indoor spaces. It is beyond the
scope of these instructions to embrace all conditions that will be encountered. All system piping
must be supported in accordance with acceptable
practice, local codes, and applicable standards.
2. INSTALLATION IN COMMERCIAL AIRCRAFT HANGARS
The Low Intensity Heaters are suitable for use in
aircraft hangars when installed in accordance with
the following. NFPA No 409 (latest edition)
A. A minimum clearance of 10 ft above either
the highest fuel storage compartment or the
highest engine enclosure of the highest aircraft which may occupy the hangar. The clearance to the bottom of the heater shall be measured from the upper surface of either the fuel
storage compartment or the engine enclosure,
whichever is higher from the floor.
B. A minimum clearance of 8 ft must be maintained from the bottom of the heater in other
sections of the aircraft hangars, such as offices
and shops, which communicate with areas for
servicing or storage. Refer to sections 8.3 to
8.5 for proper mounting clearances to combustibles.
C. Heaters must be located so as to be protected
from damage by aircraft and other objects,
such as cranes and movable scaffolding.
D. Heaters must be located so as to be accessible
for servicing and adjustment.
2.1 INSTALLATION IN COMMERCIAL GARAGES
The low Intensity Heaters are suitable for use in
commercial garages when installed in accordance
with ANSI/NFPA No. 88B 1985 (latest edition),
which states clearances to combustible construction or material in storage, from heater and vent,
must conform to standard NFPA No. 54 (ANSI
Z223.1 latest edition), in the U.S.A. and the CSA
B149.1-00, and CAN1.2.16-M81 in Canada.
“Overhead heaters shall be installed at least (8)
feet above the floor”. In addition, they shall be
located high enough to maintain the minimum
distance to combustibles, as shown on the heater
rating plate, between the heater and any vehicles
parked below the heater.
3. INSTALLATIONS OTHER THAN SPACE HEATING
Use for process applications will void the C.S.A. certification and may require field inspection and/or
certification.

7. SYSTEMS INCORPORATING 90O ELBOWS AND 180O ELBOWS
The 90o elbows are shipped as a kit with one
coupler, one reflector and one plate hanger, for
1800 elbows you must order 2 x 900 kits.
An optional angle mounting elbow kit is also
available and must be ordered with elbow kits.
The Reflectors must be secured to each of the
plate hangers, See FIG: 6 (PAGE 8).
The STV-JZ Series radiant tube heater can be
installed in configurations as illustrated in FIGURE 2. (below) with a maximum of two 90o elbows per heater. The use of radiant elbows reduces the total maximum vent allowable. See
SECTION 11 (PAGE 15): Re: Flue venting.
IMPORTANT:
On Models 155,130, 110 and 80, a mini- any elbow. And on Models STV-JZ 60 a
mum of 20’ of straight Radiant tube minimum of 10' of straight radiant tube
must be connected to the burner before
must be connected to the burner before
any elbow.

8. SUSPENSION SYSTEM
1) Survey the available structural supports, considering the system configuration and heat requirements of the area to establish the optimum heater location.
a) Locating a heater directly under joists or beams, or installing supplemental steel support
rail or angle iron can substantially reduce labour and materials
b) Consider that the heater will expand in length approximately ½ to 1inch for every 10 ft of
system length – the greater the firing rate, the greater the expansion
2) Tube system hangers must be located: 1) in line; 2) at a common height with the tube system
level; and 3) approximately 116” apart.
a) NOTE: It is important that the tubes in the system are installed in alignment horizontally
(level) and vertically (in line) – this will help prevent tube separation
3) #8 Jack Chain or equivalent is recommended for suspending the heater
a) Connect the chain to the structure using hardware as illustrated in FIGURE 8 or by other
mechanically sound means
b) If rigid devices such as rods are used for suspension, swing joints or other means must be
provided to allow for system expansion (approximately ½ inch to 1inch for every 10 ft of
system length).
4) Two types of hangers are provided to suspend the tube system – see FIGURES 3 & 4
a) Plate hangers support the tubes and reflectors at each end of the tube system
b) Webbed hangers support tubes and reflectors at each tube junction
5) Please NOTE that each hanger has a ‘flat’ side and a ‘cavity’ side – FIGURE 3

9. BURNER AND TUBE INSTALLATION
PRIOR TO PROCEEDING with the tube installation:
Refer to section “8. System Suspension”
IF a 90° or 180° elbow is to be installed in the system, refer NOW to the Elbow Kit installation instructions supplied with the elbow kit
NOTE: If a turbulator is required in the system, it is factory installed inside clearly labelled
tube(s) with instruction as to where the tube(s) must be installed at the vent end of the
system
1) All hangers must be:
a) Suspended at the same height = horizontal alignment of tubes
b) In a straight line = vertical alignment of tubes
c) Spaced 116” apart = correct spacing for reflector attachment
d) Oriented with the “cavity side” facing the burner end of the system (except the last plate
hanger at the vent end = the cavity side faces the vent)
2) Insert the swaged end of the first tube (tube with flange) through the 4” hole in the first
plate hanger – FIGURE 3
a) Ensure the ‘cavity’ side of the hanger faces the burner end of the system
b) Slide a Torctite tube coupler past the swage onto the tube
i) The final position of the coupler will be on the ‘burner-end’ side of the hanger
c) Guide the tube into the second hanger (webbed) – ensure the cavity side of the hanger
faces the burner end of the system
d) Position the first plate hanger 2 inches from the tube flange – this will ensure access to
bolt the burner to the flange
e) Check that the first tube is level
3) Install a focus shield reflector over the first tube - secure with sheet metal screws to the
hanger at each end
4) Install three reflector stabilizers on the bottom of the reflector
a) Equally space stabilizers with one at the reflector center point
b) Firmly bend the end tabs on each stabilizer up over the ‘trough’ at each side of the reflector
5) Slide a Torctite tube coupler past the swage onto the next tube to be installed
6) Insert the swaged end of the tube into the next hanger to support its weight
7) Slide the female end of the second tube over the swage of the first tube
a) Ensure that the swage on the first tube is fully inserted into the second tubeb)
b) Adjust the hanger so that it is located on the second tube, approximately 2” from the end
of the tube – in this location the hanger supports both tubes.
c) Slide the Torctite coupler into position across the center of the joint
d) IMPORTANT: TOURQUE THE COUPLER BOLTS TO 40 FT-LBS
Page 10
GP-MSJV-BX-07A
STV-JZ Manual
RD: MAR 2009
RL: 07A - BA
e) The coupler is now in place on the ‘burner-end’ side of the hanger
8) CHECK THAT THE SECOND TUBE IS LEVEL, ALIGNED HORIZONTALLY AND
VERTICALLY WITH THE FIRST TUBE – MAKE ADJUSTMENT AT SUSPENSION
POINTS AS REQUIRED
9) Install the reflector over the second tube fastening to the hangers at each end
10) Repeat the previous steps assembling one section of tube and reflector at a time until the
system is complete
11) ENSURE THAT THE SYSTEM IS LEVEL AND THAT ALL TUBES ARE ALIGNED
HORIZONTALLY AND VERTICALLY – MAKE ADJUSTMENT AT SUSPENSION
POINTS AS REQUIRED
12) Mount the Burner to the first tube flange using the four nuts and bolts provided
a) TIGHTEN THE BOLTS IN AN OPPOSITE CORNER SEQUENCE AND ENSURE
THAT THE BURNER IS IN HORIZONTAL ALIGNMENT WITH THE TUBE
13) The ‘center of gravity’ of the burner is slightly off-center to the tubes. So, in order to prevent side rotation of the burner:
Install a support chain from the eye hook on the burner to a point approximately 8 to 10
inches away (towards the burner) from the first tube hanger
i) DO NOT fasten the chain from the burner to the first hanger suspension point
ii) The chain will angle back over the burner and allow “straight back” movement of the
burner when the system heats up and expands

A length of ‘C’ Vent is to be installed on the
swaged end of the last tube before any Tee or Elbow 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.B149.1-00 latest edition for requirements.
In the USA when a heater is installed unvented
the system requires consideration of normal infiltration and introduction of outside air by natural
or mechanical means, and/or electrically interlocked to an independent exhaust fan. Consult
your local codes and ANSI Z223.1 latest edition.
for all venting requirements, and practices.
DIRECT VENTED APPLICATION
All venting must be single wall 4” diameter 26
gauge minimum 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" (JA-0528-XX) or 6" (JA-0529-XX) horizontal wall vent terminal or a high-wind termination cap approved by a nationally recognized certification agency can be used and mounted 18"
from the outside wall to the inside edge of terminal opening to alleviate back pressure caused by
turbulent wind conditions (See Fig. 17). This will
also ensure flue gases are directed away from
the structure to protect building materials from
degradation by the exhausted flue gases. It is the
sole 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.
For vertical through the roof venting, use a ‘Bvent’ termination cap as supplied by the manufacturer of the approved ‘B-vent’.

The total maximum allowable combined length of
vent and combustion air duct is 80' for STV-JZ
155 and 130, and 50' for STV-JZ 110, 80 and 60.
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 or with a 180o elbow
in the radiant tube, 10 ft or 20 ft respectively 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 location
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 degradation by flue gases.
Directly below a soffit or over- hang.
Directly above a gas utility meter or service
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.
As an Option, two heaters may be vented through
an approved common 4" X 4" X 6" Vent Tee,
supplied by the distributor. The two heaters must
then be controlled by a single common thermostat
or "ON/OFF" switch.
 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.

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.
FIGURE 14
Check with the manufacturers Technical Support
as to the maximum vent temperature requirements. The vent system must always be adequately supported to prevent sagging.
(See Fig 4 Page 8)
FLUE VENT CONNECTION
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.
PLEASE SEE SECTION 14: HEATER EXPANSION (PAGE 20).
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 is 80' for STV-JZ 155 and
130, and 50' for STV-JZ 110, 80 and 60. Neither
the individual flue vent or combustion air duct is
to exceed 50'. The total maximum allowable
combined vent /air duct is reduced by ten feet for
every 90o vent elbow installed.

RD: MAR 2009
RL: 07A - BA
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
the wall and combustion air is ducted in from out-
side 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.
Minimum air intake inlet distances:
 Three feet above grade
 Twelve inches from flue vent terminal of
heaters with input up to 100,000 Btu’s/hr.
 Three feet from flue vent terminal of any
heaters over 100,000 Btu/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.
SEE SECTION 14: ( PAGE 21) HEATER EXPANSION

GP-MSJV-BX-07A
STV-JZ Manual
RD: MAR 2009
RL: 07A - BA
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
The Btu/hr input and the tube length determine the overall expansion that occurs in a tube
system. A typical infrared tube installation will expand toward both the Burner and the vent
end. In order to address this issue it is suggested that the gas line, flue vent, and combustion
air intake (if used) shall be installed in such a manner that the normal expansion of the
heater will be accommodated.

15. ELECTRICAL AND THERMOSTAT WIRING
(SEE WIRING DIAGRAM PAGE 23)
Wiring must be done in accordance with local
codes. The total load of all heaters must be considered in determining the required contact rating
of the controlling thermostat or switch. Each tube
heater requires 120V, 60 HZ electrical power
sized for 145VA.
The heater can be controlled by the Tru-Temp
Thermostat, a line voltage Thermostat or by an
“ON/OFF" switch. Any heater(s) intended for
24v thermostat control must be ordered with the
24v control options.
IMPORTANT:
Do not install the thermostat or sensors in the direct radiant stream.
The voltage at the spark ignition control is 24V.
Note that proper functioning of the heater will be
adversely affected if the input voltage varies by
more than +/- 10%. Ambient Temperature rating
is minus 40°F to plus 175°F (-40°C to +79°C).
WARNING: The heater must be electrically grounded in accordance with the National Electrical Code. ANSi/NFPA 70 or current Canadian Electrical Code.
16. HIGH ALTITUDE INSTALLATIONS
Canada: All of the STV-JZ 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 derated, the orifice must be changed according to
the chart on page 34. Check with your local utility
regarding de-rating of this appliance.

17. LIGHTING INSTRUCTIONS
Refer to the lighting instructions on the outside
cover of the burner housing. Again, if the unit
locks out 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.
18. RECOMMENDED MAINTENANCE

Inspect the venting system each heating season and repair or replace worn parts as required.

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 air must not be obstructed.

In addition we recommend the entire system
be checked once a year by a qualified service
technician.
THE STV-JZ TUBE HEATER BURNER IS COMPLETELY FACTORY ASSEMBLED AND
TESTED. ANY ALTERATION VOIDS THE CSA CERTIFICATION AND MANUFACTURER’S
WARRANTY. FOR ADDITIONAL INFORMATION, CONTACT YOUR LOCAL DISTRIBUTOR OR MANUFACTURER.
19. SEQUENCE OF OPERATION - HONEYWELL S87J1034
STV-JZ Burner with direct spark ignition, is as follows : options #1 #2
Option #1: (120 volts)
Upon a call for heat by the line volt
age Thermostat or "ON/OFF" switch, the
blower is activated, closing a normally open
contact in the blower pressure switch

Once the flame sensor determines that
there is a flame, the spark igniter is
de-energized.

In the event ignition does not occur, the
safety circuit will function to interrupt gas
flow after approximately 21 seconds and
lock the system out. No further gas will
flow until the power has been manually interrupted for a period of 30 seconds. This
will reset the ignition module and the operating sequence will restart at step #3.

If the blower does not run, the blower
pressure switch (normally open contact)
does not close and power is not supplied to
the ignition control.
Option #2: (24 volts)
Upon a call for heat by the 24 volt Thermostat
or ON/OFF switch, the 24 volt relay will energize, closing the normally open contact to the
blower.

With the blower pressure switch contact
closed, the 30 second pre-purge cycle on
the DSI control is activated. The Spark is
energized and the gas valve opens.

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.
Shut off gas supply to the gas control
Disconnect the ignition cable at the ignition control stud terminal to isolate the circuit from the
Spark Igniter or Igniter / Sensor
 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.
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.
 Pull the wire away from the stud and note the length of gap at which spark discontinues.
 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.
 Turn off the power and reconnect the Ignition Wire to the Ignition Control stud. Disconnect the
Ignition Wire from the Igniter and repeat the steps above by grounding the wire out to the tube
body this time. Turn on the power and pull the wire away from the tube and note the length of gap
at which the spark discontinues. If there is no spark or weak spark replace the Ignition Wire.

SPARK IGNITER SET UP
Please use the following diagram for checking
the Igniter gap.

23. FLAME SENSING CIRCUIT
The output of the flame sensing circuit cannot be checked directly on the S87 body. Check the
flame sensing circuit directly by checking the flame sensing current from the sensor to the S87 as
follows.
1. Connect a meter (dc microammeter scale) in series with the flame signal ground wire as
shown below. Using the Honeywell W136A Test Meter or equivalent. Disconnect the
ground wire from the S87. Connect the red (positive) meter lead to the free end of the ground
wire. Connect the black (negative) meter lead to the quick-connect ground terminal on the S87.
2. Restart the system and read the meter. The flame sensor current must be at least 1.5 uA and steady.
If the reading is less than 1.5uA or unsteady, see LOW OR UNSTEADY FLAME CURRENT
section, below.
If a flame is present at sensor and a reading of zero uA is obtained, check for a secondary
ground connection to the 25V (GND) terminal. If secondary connection exists, temporarily
remove connection and measure flame current.
LOW/ UNSTEADY FLAME CURRENT
If the current to the S87 flame circuit is less
than 1.5 uA or is unsteady, check the burner
flame, flame sensor location and electrical connections as follows.
Electrical Connections and Shorts
Connections at the flame sensor must be clean
and tight. If wiring needs replacement, use
moisture resistant #18 wire rated for continuous duty up to 1050 C [2210 F].
