ecoSchwank and IL gas fired infra-red luminous

heaters are suitable to be installed for heating of

non-residential indoor or outdoor spaces. These

installation instructions are intended for the eco-

Schwank and IL model heaters. All installations

must conform to the following installation re-

quirements. All local, state, provincial and na-

tional code requirements including the current lat-

est edition B149.1 INSTALLATION CODE” in

Canada, and ANSI Z223.1 in the U.S.A. for gas

burning appliances and equipment. The latest edi-

tion Electrical Code PART 1 CSA C22.1 in Can-

ada 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 proce-

dures may be necessary. In case of discrepancies,

the latest installation manual will take priority.

The ecoSchwank or IL 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 sys-

tem piping must be supported in accordance with

acceptable practice, local codes, and applicable

standards.

2. INSTALLATION REQUIREMENTS

able for use in aircraft hangars when installed in

accordance with the following:

A. A minimum clearance of 10 ft above either

the highest fuel storage compartment or the

highest engine enclosure of the highest air-

craft 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 enclo-

sure, whichever is higher from the floor.

B. A minimum clearance of 8 ft must be main-

tained from the bottom of the heater in other

sections of the aircraft hangars, such as of-

fices and shops, which communicate with ar-

eas 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,

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 installers / owners responsibility and expense.

2.4 MOUNTING CLEARANCES

2.5 HEATER MOUNTING

ecoSchwank and IL Luminous Heater must be mounted with minimum clearances as shown in sec-

tions 8.3 to 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:

ecoSchwank and IL Luminous Heaters cannot be installed inside degreasing

plants, nor can they be in an area where chlorine, fluorine or bromine are present.

ecoSchwank and IL Luminous Heaters are approved for both horizontal and angle mounting. When

angle mounting, the short axis may be rotated in either direction to a maximum of 300 degrees with

the venturi always in the upper position. 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 must be

level. Use only non-combustible mounting hardware.

2.2 INSTALLATION IN COMMERCIAL GARAGES

ecoSchwank and IL Luminous 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 in Canada. “Overhead heaters shall

be installed at least (8) feet above the floor”. In addition, they shall be located high enough to main-

tain the minimum distance to combustibles, as shown on the heater rating plate, between the heater

and any vehicles parked below the heater.

The maximum supply pressure must be limited to 14" W.C. (0.51 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 regulator must be equal to or greater than 6.0" W.C. for natural gas and 11.0" W.C.

for propane gas.

A sealed regulator is supplied with the heater which maintains the proper manifold pressure when the

main burner is operating under the following pressure:

2.7 GAS SUPPLY LINE INSTALLATION

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 be provided.

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.

CAUTION: Do not install any gas piping in heat zones. Do not subject heater

controls to leak test pressures when checking the main supply piping.

INPUT CAPACITIES: Natural gas models have an orifice sized for heat content of 1000 BTU/

CU FT., and propane gas models have an orifice sized for 2500 BTU/CU FT.

2.6 VENTILATION REQUIREMENTS

Canada: Codes require 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 provide 3 cfm for every

1000 Btu/hr or fraction thereof, of total input of installed equipment. Consult CSA.B149.1 latest edi-

tion for requirements.

USA: When a heater is installed unvented the system requires the exhausting of at least 4 cfm per

1000 Bth/hr on NG, and 4.5 cfm per 1000 Btu/hr for LP. By natural or mechanical means, or electri-

cally 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 state and

local codes and ANSI Z223.1 latest edition.

3. INSTALLATION PROCEDURES

A. Properly install gas line as outlined in section 2.7, page 3.

B. Properly connect the ignition control assembly to the heater.

C. Mount heaters by using non-combustible mounting hardware as illustrated in section 8.2, page 7.

Observe the minimum clearances as outlined in sections 8.3.

D. Connect heater to the main gas line. It is recommended to use a 1/2" flexible connector to absorb

gas line expansion and any building vibration (available as option from Schwank Ltd.).

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 re-

quirements outlined in section 2.8, page 3.

WARNING:

When testing the main gas line pressure, ensure the gas shut-off valve is “OFF”,

otherwise damage to the combination gas valve will result.

G. Ensure proper electrical rating in the system 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 following the lighting instructions as shown on the next page and

on heater.

2.9 ELECTRICAL REQUIREMENTS AND THERMOSTAT CONTROL

All electrical installations must meet local and the latest edition Electrical Code PART 1 CSA C22.1

in Canada and ANSI/NFPA N0 70 in the U.S.A.. Single heater requires 24 Volt, 60 Hz electrical

transformer sized at 40 VA. If multiple heaters are connected to a single transformer, the proper trans-

former is 24 Volt, 60 Hz, sized at 40 VA for the first heater, and 20 VA each for all subsequent addi-

tions. For example, four 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.

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 local electrical code. Malfunction of the heating system will result if the voltage

varies by more than +10% or -10%.

The heater can be controlled by a line voltage thermostat, a TrueTemp thermostat or “off-on” switch.

Total load of all heaters must be considered in determining the required contact rating of the control-

ling thermostat or switch.

4. LIGHTING INSTRUCTIONS

A. Open the isolation valve in the main gas line and turn gas control knob on the combination gas

valve to the “ON” position.

B. Switch on electrical circuit by turning the thermostat to the highest temperature setting.

C. The heater should attempt ignition and remain lit within thirty seconds. Note that the correspond-

ing exhaust fan is operating properly.

D. If ignition does not occur, then cut off electrical power by turning the thermostat to off position.

WARNING:

A. Turn off electrical circuit for temporary shutdown.

B. Turn off the electrical circuit and turn gas control knob to the “OFF” position for complete shut-down.

Under certain conditions, heater may discolour due to ambient air borne particle deposits on the outside sur-

face. These deposits in no way affect the operation of the heater nor the manufacturer’s warranties.

5. SHUT DOWN INSTRUCTIONS

If heater back-fires during operation, then it must be turned off immediately.

Indication of back-firing:

A. Loud ignition noise, then followed by dis-

tinct hissing sound.

B. Little or no visible burning on the ceramic

tile.

C. Combustion is taking place inside the burner

body.

Cause & remedy of back-firing:

A. Improper gas pressure entering the venturi

tube = check pressure.

B. Breakage of a ceramic tile and or gasketing

= replace damaged part.

C. Faulty sealing of the ceramic tile to the

burner body, caused by breakdown of gas-

keting material = contact your Schwank dis-

tributor.

6. AIR BORNE PARTICLES

7. SERVICING GUIDE

Servicing of heater is essential for continued efficient operation. Servicing should be carried out

annually by qualified service personnel.

Clean the ceramic tile with compressed air. Avoid directing the air stream at the gasketing mate-

rial located between the tile and heater body. The air pressure must be lower than 20 psi.
