Premier Models: STS-JZ / IQ: Competitively priced higher radiant efficiency
P40U Series: Factory assembled 40,000 Btuh x 10 ft; Low input rate for Builder or Premier
steel water resistant burner enclosure; aluminized steel tube/reflector system.
STW-JZ2 / IW2 Models have a stainless steel tube/reflector system; stainless steel tube/
reflector is not available in the P40U packaged model.
It is a normal condition that during heat-up and cool-down a tube
heater will expand and contract. Allowances for heater expansion
must be made in the gas connection, venting and combustion air
ducting. Improper installation, alteration, or adjustment can result in
WARNING
Gas Connection
Improper installation, connection, or adjustment can result in property
damage, toxic gases, asphyxiation, injury or death. Use the approved
Type 1 hose gas connector supplied with the heater to connect the
heater to the gas supply. The gas supply must be connected tested in accordance with all local, state, provincial, and national codes (ANSI Z223.1/NFPA 54 in USA; B149.1 in Canada)
and as indicated in this manual. Refer to Section 13
WARNING
Venting
Inadequate venting of a heater may result in asphyxiation, carbon
monoxide poisoning, injury or death. This heater may be directly or
indirectly vented from the space. Venting must be in accordance with
all local, state, provincial, and national codes (ANSI Z223.1/NFPA 54 in USA;
B149.1 in Canada) and as indicated in this manual. Refer to Sections 11 & 12
WARNING
Start-Up ‘SMOKE’ Condition
During start up, the heating of material coatings used in the production process of tubes and
reflectors will create smoke during the initial period of operation. This condition is normal and
temporary .
Ensure that there is sufficient ventilation to adequately clear any smoke from the space.
Notify site and safety personnel to ensure that alarm systems are not unduly activated.
WARNING
Tube “GLOW”
It is a normal condition that the combustion tube (1st tube) can appear to “glow red”. For inputs
up to 150,000 Btuh, the top surface of the tube can appear red where heat is trapped between
the reflector and the tube. The stainless steel tube used for inputs 175,000 and greater appears to entirely glow red. The tube material is designed into the heater because it can withstand the high temperature of combustion, and the “red glow” is a normal occurrence.

WARNING
Clearance to combustibles
Location of flammable or explosive objects, liquids or vapors close to the heater may cause fire
or explosion and result in property damage, injury or death. Do not use, store or locate flammable or explosive objects, liquids or vapors in proximity of the heater.
The clearance to combustible material represents the minimum distance that must be maintained between the outer heater surface and
a nearby surface. The stated clearance to combustibles represents a
surface temperature of 90F° (50C°) above room temperature. It is the
installer’s responsibility to ensure that building materials with a low
heat tolerance which may degrade at lower temperatures are protected to prevent degradation. Examples of low heat tolerance materials include vinyl siding, fabrics, some plastics, filmy materials, etc.
In locations used for the storage of combustible materials, signs must be posted to specify the
maximum permissible stacking height to maintain the required clearances from the heater to
the combustibles. Such signs must either be posted adjacent to the heater thermostats or in
the absence of such thermostats in a conspicuous location. In addition to stored or stationary
material, consideration must also be given to moveable objects such as cranes, vehicles, and
overhead doors, and structural objects such as sprinkler heads, electrical and gas lines, and
electrical fixtures.
It is beyond the scope of these instructions to consider all conditions that may be encountered.
Consult local authorities such as the Fire Marshall, insurance carrier, or safety authorities if you
are uncertain as to the safety or applicability of the proposed installation.
Refer to Figure 1 and Table 1 for the certified clearances to combustibles for the appropriate model input/size.

property damage, injury or death. Read and understand this installation and
operation manual thoroughly prior to assembly, installation, operation or service to
this appliance.
This heater must be installed and serviced only by a trained gas service technician.
Do not store or use gasoline or other flammable vapours and liquids in the vicinity
of this or any other gas fired appliance.
Failure to comply could result in personal injury, death, fire and/or property damage.
Do not store or use gasoline or other flammable vapours and liquids in the vicinity
of this or any other gas fired appliance.
5. PRE INSTALLATION SURVEY
It is recommended that a full heating design including heat loss calculation be conducted on
the structure or area to be heated. Heater sizing and placement must consider available
mounting height, sources of greatest heat loss, and the certified clearances to combustibles
with respect to stored material, moveable objects (cranes, vehicles, lifts, overhead doors, etc),
sprinkler system heads, and other obstructions on the site. Consideration must also be given to
vent / duct placement and the allowable combined lengths of vent and duct. Carefully survey
the area to be heated, and for best results place burner and combustion chamber in the coldest
area(s) .
Installation must conform with all local, state, provincial and national code requirements including the current latest edition ANSI Z223.1 (NFPA 54) in the U.S.A. and B149.1 installation
code in Canada, for gas burning appliances and equipment. The latest edition Electrical Code
ANSI/NFPA N0 70 in the U.S.A. and PART 1 CSA C22.1 in Canada must also be observed.
The heating system must have gas piping of the correct diameter, length, and arrangement to
function properly. For this reason, a layout drawing is necessary.

6. MOUNTING CLEARANCES
This heater must be mounted with at least the minimum clearances between the heater and
combustibles as shown in FIG-1, TABLE 1, Page 7. It is the installer’s responsibility to ensure
that building materials with a low heat tolerance which may degrade at lower temperatures are
protected to prevent degradation. Examples of low heat tolerance materials include vinyl siding, fabrics, some plastics, filmy materials, etc.
Positioning of lights, sprinkler heads, overhead doors, storage areas, gas and electrical lines,
parked vehicles, cranes and any other possible obstruction or hazard must be evaluated prior
to installation.
Ensure adequate clearance around the air intake at the burner to allow sufficient combustion air supply to the heater.
6A. SERVICE CLEARANCE
: The lower ‘jaw’ of the burner cabinet swings down to provide
convenient service access to burner components. Provide a minimum clearance from any wall
or obstruction of 6 inches (15 cm) to the access end of the burner housing, and a minimum of
24 inches (61 cm) to any ONE side to allow servicing of burner, blower and controls. (see Figure 2 below) - the minimum clearances to combustibles must always be maintained.
For guidelines to heater placement refer to TABLE 2 (next page).
* GUIDELINE MOUNTING HEIGHTS are typical to provide optimum comfort in general space
heating applications. Variance to these typical heights can occur in some applications:
Higher mounting heights due to structure or application requirements
Lower mounting heights: Area or ‘spot’ heat; locations with sufficient horizontal separa-
tion distance from personnel; areas with greater infiltration losses (near overhead doors,
etc)
IMPORTANT: Single or multiple heater placement must be such that continous
operation of heater(s) will not cause combustible material or materials in storage to reach a temperature in excess of ambient temperature plus 90F° (50C°).
It is the installer’s responsibility
to ensure that building materials with a
low heat tolerance which may degrade at lower temperatures are protected to prevent degradation. Examples of low heat tolerance materials
include vinyl siding, fabrics, some plastics, filmy materials, etc.
Refer to “Clearance to Combustibles” information on pages 6 to 8, and

7. SUSPENDING THE SYSTEM - GENERAL
Inadequate or improper suspension of the tube heater can result in collapse of
the system, property damage, and personal injury or death.
It is the installer’s responsibility to ensure that the hardware and structural supports from which the heater is suspended are sound and of adequate strength
to support the weight and expansion forces of the heater.
Consider that the heater will expand in length as much as 1/2 inch (12.5 mm) or more for every
10 ft (3 m) of system length – typically the greater the firing rate, the greater the expansion.
Refer to Sections 13 & 14
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 labor and materials
2) Tube system hangers must be located: A) straight in line; B) at a common height (level);
and C) 116” (295 cm) apart.- see Figure 6 next page.
a) NOTE: It is important that the tubes in the system are installed in alignment horizontally
(level) and vertically (in line) – this will ensure system integrity
3) Hardware with a minimum 60 lb. (30 kg) work load must be used at each heater suspension
point. A #8 Jack Chain or equivalent is typically used for suspending the heater.
a) Connect to the structure using typical hardware as illustrated in FIGURE 5 (below) or by
other mechanically sound means
b) If rigid devices such as 3/8” threaded rods are used for suspension, swing joints or other
means must be provided to allow for system expansion - approximately ½ inch to 1 inch
for every 10 ft (1 cm to 2.5 cm for every 3 m) of system length.
4) Two types of hangers are provided to suspend the tube system – see FIGURES 6 & 7
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

7-A. SEISMIC RESTRAINT - LATERAL AND LONGITUDINAL
In areas prone to earthquake, or as specified on a project, install lateral and longitudinal seismic restraints as indicated in Figure 11. If the heater location can be impacted by wind (aircraft
hangars, etc) refer to High Wind Restraint section 8-B.
These restraint systems indicate suspension of and attachment to the heater. The attachment
of suspension hardware to the structure will be as required by site structural conditions, installation codes, and/or local engineering design requirements. Other types or systems of restraint
may be specified by local or national codes, or by project engineering design specifications.
Schwank / InfraSave offers optional items: #2 Lion Chain 115 lb work load x 200 ft roll (PN: JL0800-XX); and Safety Snap Hooks (PN: JL-0800-SH = pkg 24; JL-0800-SH-B = pkg 100).
All other required seismic mounting hardware is field supplied by the installer.
FIGURE 11
7-B. HIGH WIND RESTRAINT - LATERAL, LONGITUDINAL, AND VERTICAL
In areas with wind conditions (aircraft hangers, etc) in addition to lateral and longitudinal restraint the heater must be restrained from vertical movement. Suspend the heater using 3/8”

8. SYSTEMS INCORPORATING 90° ELBOWS AND 180° ELBOWS
A radiant tube heater can be installed in configurations as illustrated in FIGURE 4. (below) with
a maximum of two 90° elbows per heater. The use of elbows reduces the total maximum vent
allowable. (See Section 11 : Flue venting)
90° elbows (JS-0528-JZ) are shipped as a kit with one coupler, one reflector and one plate
hanger. For a 180° elbow, order 2 x 90° kits that connect to create a 180°. An optional kit
(JS-0504-JZ) to angle mount a reflector adjacent to an elbow is also available and must be ordered separately. The reflectors must be secured to each of the elbow plate hangers, See
PAGE 19
IMPORTANT: Models with input 100 Mbh x 20 ft (30 kW x 6 m) must only be in-
stalled as a straight system with no elbows allowed at the 10 ft (3 m) location.
Elbow Location / Input: A minimum run of straight radiant tube must be con-
nected to the burner before any elbow as follows: Inputs 200,000 and 175,000
= 25 ft (7.6 m); 150,000 = 20 ft (6 m); 130,000 and 110,000 = 15 ft (4.6 m); and
inputs 80,000 and 60,000 a minimum of 10 ft (3 m) straight tube before elbow.
FIGURE 3 SYSTEM ELBOW KIT - see page 53 for 180° elbow dimensions
Angle mounting of the reflector system either side of an elbow requires adapter JS-0504-JZ. The elbow always remains
in a horizontal orientation.

all subsequent tubes are painted steel. The first tube (titanium alloy stainless steel )
will “glow red” while heater is in operation - THIS IS A NORMAL CONDITION
3. IF a 90° or 180° elbow is to be installed in the system, refer NOW to Section 8
and the Elbow Kit installation instructions supplied with the elbow kit
4. TURBULATORS: Also refer to Table page 24155 Models (150,000 Btuh): 2 ft turbulator supplied in the Burner Kit and field installed:
155 x 40 ft heater: Insert 2 ft turbulator in end of third tube, prior to the 10 ft tur-
bulator that is factory installed in the last tube (total 12 ft turbulator)
155 x 50 ft heater: Insert in the vent end of the last tube in the system.
All other turbulators are factory installed inside tube(s) that are clearly labeled
with instruction as to where the tube(s) must be installed - Also see page 24
ALL MODELS: INSTALL THE FIRST AND SECOND TUBES (FROM BURNER END) WITH THE
WELDED SEAM (ALONG THE TUBE LENGTH) FACING DOWNWARD
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" (295 cm) apart = correct spacing for reflector attachment
d) Orient hangers 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" (10 cm) hole in the first
plate hanger (WELDED SEAM FACING DOWNWARD)
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
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 2.5 inches (6.4 cm) from the tube flange – this will provide
access to bolt the burner to the flange, and ensure correct spacing of consecutive system
hangers
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 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 tube
b) Adjust the hanger so that it is located on the second tube, approximately 2" (5 cm) 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

WARNING
11. FLUE VENTING
Inadequate venting of a heater may result in asphyxiation, carbon monoxide
poisoning, injury or death. This heater may use a vent connection or indirect
venting system to remove products of combustion from the space. Seal all vent
connections with high temperature sealant. Venting must be in accordance with
all local, state, provincial, and national codes (ANSI Z223.1/NFPA 54 in USA;
B149.1 in Canada) and as indicated below in this manual.
Indirect venting must not be used if the building experiences a negative air condition. A minimum 3 ft (91 cm) length of single walled vent pipe is to be installed on the swaged end of the
last tube.
USA: Natural or mechanical means shall be provided to supply and exhaust at least 4ft3/
min/1000Btuh (0.38m3/min/kW) input of installed heaters. Some local codes may require an
electrical interlock to a dedicated exhaust fan. Exhaust must be located as high as practicable
in the structure above the level of the heater(s). Consult your local code and ANSI Z223.1 latest edition for all venting requirements and practices.
Canada: It is required that the heater(s) be electrically interlocked to dedicated exhaust fan(s)
by means of an Air Proving Switch. Exhaust fan(s) must be sized to create 300 cfm (8.5 cu m/
min) exhaust for every 100,000 Btuh (30 kW) or any fraction thereof of total input of installed
equipment. Exhaust must be located as high as practicable in the structure above the level of
the heater(s). Sufficient supply air must be provided. Consult the latest edition of CSA.B149.1
Section 8 for venting system and air supply requirements.
VENTED DIRECTLY TO THE OUTSIDE
It is the sole responsibility of the installer to adhere to all current local codes and/or ANSI
Z223.1 / CSA.B149.1 latest editions for all venting requirements, and practices.
It is a normal condition that during heat-up and cool-down a tube heater will expand and contract. Allowances for heater expansion must be made in the venting and combustion air ducting
.
Improper installation can result in property damage, injury or death.
All vent pipe and adapters are supplied locally by others
All venting must be minimum 26 gauge single wall vent pipe of 4” (10 cm) diameter except
that portion of vent passing through a combustible wall or roof can be 4” type “B” vent as per
CSA International’s interim requirement. Refer to Section 11A for vent length requirements.
As an Option, two heaters may be vented through an approved common 4" x 4" x 6" Ven t
Tee (10 x 10 x 15 cm), supplied by the manufacturer. Vent pipe from each heater does not
need to be equidistant to the vent Tee, but must comply to requirements below. The two

heaters must be controlled by a single common thermostat or “ON/OFF” switch.
Install a minimum 36 inch (91 cm) length of minimum 26 gauge single walled 4” (10 cm) di-
ameter vent pipe on the system, and a minimum 12 inch (30 cm) before any Tee or Elbow.
Seal all vent connections with high temperature sealant. Vent connections must be secured
with three (3) #8 sheet metal screws uniformly spaced around the circumference of the pipe.
Any horizontal vent pipe must slope approx. 1/4” per foot away from heater
When the vent pipe passes through a cold or unheated area where the ambient temperature
is likely to produce condensation of the flue gases, the vent pipe will be insulated with a suitable material as approved and specified by the insulation manufacturer to withstand temperature up to 460°F (238°C).
The vent system must always be adequately supported to prevent sagging.
* Other means of slip
fit installation of the
vent and duct are acceptable providing
there is adequate allowance for free expansion and contraction of the system,
and free flow of vent
gases and combustion air.

12. COMBUSTION AIR DUCTING
Do not install filters on the combustion air intake.
Ensure adequate clearance around the air intake to allow sufficient combustion air supply to the heater.
An opening is located on the top surface of the burner housing for combustion air . Ensure
adequate clearance around this opening to allow sufficient combustion air supply to the heater.
Combustion air duct must be constructed of noncombustible material.
When a tube heater is vented to the outside and operated in a negative air condition or air-born
dust or contaminants are present as in woodworking and welding shops, air for combustion
must be ducted from outside the negative or contaminated area to the 4 inch (10 cm) diameter
intake flange supplied on the blower. Maximum system, vent and duct length is listed above.
The total system length and individual flue vent or the combustion air duct is not to ex-
ceed the lengths listed above
Total combined system length is reduced by five feet for every 90° elbow installed in the
vent or duct and in the tube system (see above for allowable total lengths)
Exceeding the allowable lengths may create condensation or soot conditions and will void
CSA Design Certification and product warranty
The air intake will not be located less than:
Three feet above grade
Twelve inches from flue vent terminal of any heater with input up to 100,000 Btu/hr
Three feet from flue vent terminal of any heater over 100,000 Btu/hr
This heater has an optional fresh air intake duct hood for wall (JS-0532-VC) or roof cap (JS0530-XX) to bring combustion air to the heater from outside. Ensure adequate clearance
around the air intake to allow sufficient combustion air supply to the heater. If drawing fresh air
from outside, it is recommended that any single wall pipe containing cold air be insulated to
prevent or reduce condensation on the pipe.
CAUTION: If a tube system is indirectly vented, ensure that warm moist outside air is not
drawn through the air duct and tube system during summer months - condensation can occur
inside the system and cause damage.
Do not use flexible dryer hose or any ‘soft wall’ tubing for air inlet duct, the corrugated sides
of this tubing restrict air flow. A good quality industry approved insulated flex is allowed.
CAUTION: In locations where chlorinated Hydrocarbons are in use, such as
Trichloroethylene or Chloroethylene Nu it is essential that combustion air be
brought in from a non-contaminated area. 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.
The heater manufacturer cannot anticipate all types and chemical composition of
possible contaminants at project sites. Confer with project site safety, health and
engineering staff and/or local authorities having jurisdiction such as the Fire Marshall and Department of Labor for possible contaminants and any conflict with the
installation of hot surface heating equipment.

13. GAS SUPPLY - HEATER EXPANSION - FLEXIBLE GAS CONNECTION
The gas supply must be installed to the heater using:
USA: an approved Stainless Steel Flexible Gas Connector certified for use on an infrared
radiant tube heater (ANSI Z21.24 CSA 6.10);
CANADA: an approved Type 1 Hose Gas Connector (CAN/CGA 8.1).
The heater must be isolated from the gas supply piping s ystem by closing its individual
manual shut off valve (field supplied) during any pressure testing of the gas supply piping
system.
CAUTION:Compensation for normal gas supply pipe expansion, and radiant tube heater
expansion must be provided. All piping must conform to local codes— Refer to
Heater Expansion & Flexible Gas Connection—Sections 14 next two pages
Provide a 1/8 in (3.2 mm) NPT plugged tapping, accessible for test gauge connection, immediately upstream of the gas supply connection to the heater.
DO NOT use pressure 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.
TABLE 4
GAS TYPE
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: Minimum supply line pressure at the inlet to the heater regulator must not be lower than 5.0 inches of water column pressure for natural gas. The supply gas pressure must be checked with all heaters in operation.
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 can cause property damage, injury or death and will void
the heater warranty.

Wrench is necessary to check this. When checking or setting the manifold pressure, a water manometer should be used. Gauges which measure in ounces per square inch or pounds
per square inch are not accurate enough to properly measure or set the pressure.
WARNING
THIS HEATER WILL EXPAND IN LENGTH AS IT HEATS UP. It is a normal
condition that during heat-up and cool-down a tube heater will expand and contract. Allowances for heater expansion must be made in the gas connection, venting and combustion air ducting. Improper installation, alteration, or adjustment
can result in property damage, injury or death. See also Section 13
The Btuh input and the tube length determine the overall expansion that occurs.
A typical infrared tube installation will expand toward both the Burner and the
vent end.
To allow heater expansion the gas supply must be installed using:
In the USA: a stainless steel Flexible Gas Connector certified for use on an
infrared radiant tube heater (ANSI Z21.24 CSA 6.10);
in CANADA: a Type 1 Hose Connector (CAN/CGA 8.1). Also the flue vent,
and combustion air intake (if used) must be installed in such a manner that
the normal expansion of the heater will be accommodated.
IMPORTANT: See next page: orientation of connection between heater and gas supply.

The heater must be electrically grounded in accordance with the
NOTICE
National Electrical Code. ANSI / NFPA 70 or current Canadian
Electrical code CSA C22.1.
Appliance and control wiring must be in accordance with all applicable 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 includes a 24V/120V relay switch and can be controlled by a 24V Thermostat, a TruTemp Thermostat, a line voltage Thermostat or by an “ON/OFF” switch. Maximum
power flow for internal 24V burner components is 21VA.
A maximum night set-back of 9°F (5°C) is recommended for optimum economy and comfort.
To maintain satisfactory comfort levels do not turn off the heating system over night/weekends.
15. HIGH ALTITUDE INSTALLATIONS
- also refer to chart in Section 28
When installed above the altitude stipulated below for the USA or Canada, the input must be
de-rated by 4% for each 1000 ft above the altitude listed . If your local utility supplies gas with a de-rated heat content, no orifice change is required in the heater . If the gas supply
is not de-rated, the orifice must be changed according to the chart in Section 27. Check with
your local utility regarding the gas supply and the de-rating of this appliance. Maintain gas supply pressures indicated in Table 4, page 33.
USA: The factory installed orifice for this appliance is approved for altitudes zero to 2000
feet above sea level. When installed above 2000 feet, refer to Section 28.

20 SEQUENCE OF OPERATION GASLITER 50N DIRECT SPARK IGNITION (DSI)
The Gasliter 50N is a three trial ignition control module with a 30 minute soft lockout/reset. It is
powered by a 24v transformer that is activated when the thermostat calls for heat. On every
call for heat the Gasliter 50N will delay start-up to provide a 30 second system pre-purge.
When the Gasliter 50N is activated by a thermostat or call for heat an internal transformer provides power to the electronic generator circuit for Spark Ignition and the retrial/safety lockout
timing begins. At the same time, the Gasliter 50N opens the gas control valve allowing gas to
flow to the main Burner.
The Gasliter 50N Control Module performs the following basic functions:
· Provides a 30 second system pre-purge
· Supplies power to the electronic pulse-generator circuit for the Spark Igniter (30,000 volts
open circuit).
· Allows up to three 20 second Trials For Ignition (TFI) before a ‘soft’ system safety lockout
of 30 minutes occurs.
· Three time TFI and soft 30 minute lockout repeat
· Senses the Burner flame for safe lighting
· Shuts off the spark after the Burner is lit.
Burner with direct spark ignition, sequence is as follows :
1a. Line Voltage Thermostat: Upon a call for heat by the line voltage Thermostat or “ON/
OFF” switch, the Blower and the 120/24 volt Transformer are powered simultaneously with
115 volts. …. continue to 2.
1b. 24 Volt Thermostat: The 120 volt supply to heat er will power the 120v/24v Transformer
and the 120V side of the Blower switching relay simultaneously. A call for heat by the 24
volt Thermostat energizes the 24 volt control circuit and the 24v/120 volt relay powering the
Blower.
2. The 24 volt control circuit power s the DSI control in series through the normally open Air
Pressure Switch (APS) and the normally closed Blocked Flue Switch (BFS).
3. The Blower creates a positive pressure and closes a normally open contact inside the Air
Proving Switch (APS).
4. Provided there is no blockage in the system (tube and vent), the Blocked Flue Switch re-
mains in a normally closed position.
5. 24 volts supplied to the DSI control initiates the 30 second pre-purge cycle.
6. After completing the 30 second pre-purge cycle the DSI control generates high voltage to
the Spark Igniter, and 24 volts to energize the Gas Valve.
7. The Burner will light and establish a steady flame.
8. Once the flame sensor determines there is a steady flame established, with a minimum
flame signal of 1.5 µA the spark igniter is then de-energized.
9. In the event ignition does not occur, the DSI control will retry the ignition sequence up to an
additional two trials. If ignition does not occur after the third ignition trial, the system will enter a 30 minute ‘soft’ lock-out. This will reset the ignition module and the operating sequence will restart at step #1 after the 30 minute lock-out period.
10. If there is a loss of flame during the run mode, the unit will energize the spark within 0.8
seconds and perform a T.F.I., without the gas valve being closed first, this is called Spark
Restoration. If a flame is not established during Spark Restoration the unit will repeat the
process in step number 9 (above).

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, personal injury, or death 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. (3 mm) or more indicates satisfactory voltage output. If no arc can
be established, or the maximum spark is less than 1/8 in. (3 mm), 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
Use the following diagram to check the Igniter gap. If the gap is incorrect all adjustments
should be made with the GROUND PRONG/PIN ONLY! DO NOT BEND THE IGNITER
