The gas fired infra-red luminous heaters are suit-

able to be installed for heating of non-residential

indoor or outdoor spaces. These installation in-

structions are intended for the ecoSchwank-

MILLIVOLT / IL-MILLIVOLT heaters. All

installations must conform to the following instal-

lation requirements. All local, 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, revision to our equipment and

installation procedures may be necessary. In case

of discrepancies, the latest installation manual

will take priority.

The ecoSchwank-MILLIVOLT / IL-

MILLIVOLT heater may be installed for heating

of non-residential indoor spaces. It is beyond the

scope of these instructions to embrace all condi-

tions that will be encountered. All system piping

must be supported in accordance with acceptable

practice, local codes, and applicable standards.

2. INSTALLATION REQUIREMENTS

Luminous Heaters are suitable for use in aircraft

hangars when installed in accordance with the fol-

lowing:

A. A minimum clearance of 10 ft above either the

highest fuel storage compartment or the high-

est 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 stor-

age compartment or the engine enclosure,

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 offices

and shops, which communicate with areas for

servicing or storage. Refer to sections 9.3 to

9.5 for proper mounting clearances to com-

bustibles.

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.

RL: 1D

2.3 INSTALLATIONS OTHER THAN SPACE HEATING

Use for process applications will void the C.S.A. certification and require governing authority field cer-

tification at the installers / owners responsibility and expense.

2.4 MOUNTING CLEARANCES

2.5 HEATER MOUNTING

The Luminous Heater must be mounted with minimum clearances as shown in sections 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.

Luminous Heaters cannot be installed inside degreasing plants, nor can

they be in an area where chlorine, fluorine or bromine are present.

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 30degrees with the venturi always in the

upper position. Improper angle mounting can result in damage to the heater or unsafe operation.

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

The 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 ma-

terial 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 maintain 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 pro-

pane 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.

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

to leak test pressures when checking the main supply piping.

 Natural gas: 1,000 BTU/CU FT.

 Propane gas: 2,500 BTU/CU FT.

2.6 VENTILATION REQUIREMENTS

Canada: it is required by law that an unvented heater be electrically interlocked to an independent ex-

haust 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 latest edi-

tion for requirements.

USA: when a heater is installed unvented the system requires the exhausting of at least 4 cfm per 1000

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

ent 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.

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 Diagrams 2 on page 8.

Observe the minimum clearances as outlined in sections 9.3 to 9.6.

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)

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.

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.

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

“OFF”, otherwise damage to the combination gas valve will result.

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.

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

Indication of back-firing:

A. Loud ignition noise, then followed by distinct

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 gasketing ma-

terial = contact your Schwank distributor.

4. AIR BORN PARTICLES

5. SERVICING GUIDE

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

ally by qualified service personnel.

A. Clean the ceramic tile with low pressure compressed air. Avoid directing air stream at the gasketing

material between the tiles and heater body. The air pressure must be lower then 20 psi.

B. Clean the venturi tube with compressed air.

C. Clean the reflectors.

8.1 MAINTENANCE

The efficiency of the heater can be impaired if it gets dirty. If the heaters are installed in areas where consider-

able dust is present in the air, periodic burner cleaning may be necessary. Dust may be entrained in the primary

air supply and deposited on the back side of the ceramic tiles. This can be very easily removed by cleaning the

ceramic face and the air inlet with a blast of low pressure

air, a maximum of 20 psi. Do not direct the air stream at

the gasket material between the tiles and burner body.

Occasionally pilots or the main burner refuse to function

properly after a summer shutdown. For the pilot, this prob-

lem can be corrected by removing the pilot burner and

cleaning out the gas passageways. The main burner pas-

sageways can be cleaned out by using a flexible brush

comparable to the type used to clean glass bottles. (In

several instances, small cocoons or spider webs have

been found present in these areas.) Preventative mainte-

nance is the best policy. Heaters should be cleaned once

a heating season.
