2.2 INSTALLATION IN COMMERCIAL GARAGES
The Schwank Combined 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, 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
2.3 INSTALLATIONS OTHER THAN SPACE HEATING
Use for process applications will void the
C.S.A. certification and require governing
authority field certification at the installer’s /
owner’s responsibility and expense.
2.4 MOUNTING CLEARANCES
The primoSchwank / supraSchwank Com-
bined Intensity Heater must be mounted with
minimum clearances as shown in sections 8.3
and 8.5. It should also be located with
respect to building construction and equipment so as to provide sufficient clearance
and accessibility for servicing and cleaning
of burners and ignition control.
WARNING:
The Schwank Combined Intensity Heaters cannot be installed inside degreasing plants, nor can they be in an area
where chlorine, fluorine or bromine are present.
2.5 HEATER MOUNTING
The Schwank Combined Intensity Heaters are
approved for both horizontal and angle
mounting. When angle mounting, the short
axis may be rotated to a maximum of 30 degrees. The Venturi alignment varies with NG
and LPG applications. Therefore it is very im-
important, and critical to install the heaters
with the venturi positioned as per the manufacturers instructions. Improper angle
mounting can result in damage to the heater
or unsafe operation.
IMPORTANT:
For either horizontal or angle mounting, the long axis of the heater body
must be level. Use only non-combustible mounting hardware. Diagrams 2
on page 6 illustrate typical suspension hardware that is approved.

2.6 VENTILATION REQUIREMENTS
In Canada it is required by law that an unvented heater be electrically interlocked to an
independent exhaust fan by means of an Air
Proving Switch. The exhaust fan must be
sized to create 3 Cfm 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 re
A. All piping must be installed according to
local codes.
B. It is recommended to install an approved
flexible connector between the heater and
gas piping available as option from
Schwank.
C. A drip-pocket at the inlet connection must

Do not install any gas piping in heat zones. Do not subject heater
controls to leak test pressures when checking the main supply
piping.
quires the exhausting of at least 4 Cfm per
1000 Btuh/hr on NG, and 4.5 Cfm per 1000
Btu/hr for LP. By natural or mechanical
means, or electrically interlocked to an independent exhaust fan, for the total input of
all heaters installed. Exhaust openings for
removing flue products shall be above the
level of the heaters.. Consult your local
codes and ANSI Z223.1 latest edition.
D. On propane-fired units, a main line filter
is recommended.
E. Piping joint compounds must be resistant
to the action of liquefied petroleum gases.
F. All piping joints should be tested for
leaks with a soap and water solution.
2.7 GAS PRESSURE
The maximum supply pressure must be limited to 14" W.C. (0.5 psi). If the line pressure
is above 14" W.C., then a separate pressure
reducing regulator must be used. The minimum pressure at the inlet to the heater regula-
for NG and 11.0" w.c. for LPG. A sealed
regulator is supplied with the heater which
maintains the proper manifold pressure when
the main burner is operating under the following pressure:

2.8 ELECTRICAL REQUIREMENTS AND THERMOSTAT CONTROL
All electrical installations must meet local
and Canadian Electrical Code Part CSA
C22.1. Single heater requires 24 Volt, 60 Hz
electrical transformer sized at 40 VA. If multiple heaters are connected to a single transformer, the proper transformer is 24 Volt,
60 Hz, sized at 20 VA per heater. For example, five heaters wired together (parallel), require a transformer of 100 VA.
It is not recommended to install more than 12
heaters per zone. PROPER WIRING POLARITY MUST BE MAINTAINED, particularly when grouping the heaters in a zone.
3. INSTALLATION PROCEDURES
A. Properly install gas line as outlined in
section 2.7, on page 3.
B. Properly connect the ignition control as-
semblies to the heater.
C. Mount heaters by using non-combustible
mounting hardware as illustrated in Diagrams 2 & 3 on page 7. Observe the minimum clearances as outlined in sections
8.3 and 8.7.
D. Connect heater to the main gas line. It is
recommended to use a 1/2" flexible connector to absorb gas line expansion and
Total wiring distances of up to 200' must use
minimum 16 gauge electrical wire, and wiring distances of over 200' must use minimum
14 gauge electrical wire. The heater must be
electrically grounded in accordance with the
electrical code.
The heater can be controlled by a line voltage
thermostat, a black bulb sensor with control
or “off-on” switch. Total load of all heaters
must be considered in determining the required contact rating of the controlling thermostat or switch.
any building vibration (available as
option from Schwank Inc.)
E. Mount thermostat at desired location,
away from direct infra-red rays of heater
and not on cold wall without sufficient
insulation backing. Install exhaust fan, air
switch and transformer, as per section
2.6, page 3 and section 2.9, page 4.
F. Check gas line for leakage by using soap
test or gas meter test. Ensure gas pressure
meets the requirements outlined in section 2.8, page 3.
WARNING:
When testing the main gas line pressure, ensure the gas shut-off
valve supplying the heater is “OFF”, otherwise damage to the
combination gas valve will result.
G. Ensure proper electrical rating in the sys-
tem by checking voltage at ignition module terminals. To avoid system malfunction, the voltage range must be within
21.6 volts to 26.4 volts.
H. Test fire the heating system by follow-
ing the lighting instructions as shown
on the next page and on heater.

9. HIGH ALTITUDE INSTALLATIONS
In Canada all of our Luminous heaters are
approved for altitudes zero to 2000 ft above
sea level, or 2000 ft to 4500 ft above sea level
and must be ordered as such, for either High
or Low altitude.
In the USA if a heater is to be installed at altitudes above 2000 ft, the input must be reduced by 4% per 1000 ft and the orifice must
be changed. (Contact your local distributor or
Schwank for further technical information).
10. SEQUENCE OF OPERATION FOR HONEYWELL S87C DSI CONTROL
1. On A call for heat the S87C DSI Control
will check for a false flame condition /
short to ground. The module will lock out
if a false flame condition is present.
(Reset is usually done from the Thermostat manually).
2. Spark (30,000 volts) is generated at the
Spark Ignition Stud, for direct ignition
of the main Burner by the single Spark
Igniter.
3. Main Gas Control Valve is powered and
OPENS lighting off the Main Burner.
4. Separate Flame Sensor, relays the pres
ence of Main Burner flame back to the
DSI Control by a rectified dc voltage
signal. (TFI period)
6. This is the 21 second T.F.I (Trial For Ignition) period where flame has to be established first, and confirmed with a minimum signal strength of 1.5 microamps
back to the DSI Control. Failing this the
DSI will go into the Safety Lockout Mode
and shut down the Burner. (Reset is
manually done from the Thermostat).
7. On a loss of power the S87 allows the system to shut down safely. Start up is initiated when power is restored
8. On a loss of Main Burner flame, the
timed T.F.I. is repeated.
Safety Lock-out occurs if the flame is
not re-established within the T.F.I
period, (Reset is manually done from
the Thermostat.)
5. If this dc signal is a minimum of 1.5 uA
(microamps) the flame remains estab-
lished and the DSI Control discontinues
the ignition spark.

11. 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
