INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS FOR

SERIES OK3 – INFRARED RADIANT HEATERS

FIRE/EXPLOSION HAZARD WARNING - During operation, take precautions to ensure that

combustible materials are always kept at a safe distance from the radiant energy. This heater is

not intended for use in hazardous areas where flammable vapours, gases or liquids or other

combustibles are present. Remember that objects placed under an infrared heater can take a while

to reach stabilized temperatures. If you are unsure of the suitability of the heater for the intended

application, check with the factory for recommendations. Failure to comply can result in personal

injury and/or property damage.

DESCRIPTION

1.0

The OK3 radiant heaters are suitable for comfort heating

use in non-hazardous areas protected from rain, snow or splashing,

where heating element temperatures in excess of 750°C(1382°F)

will not present the risk of fire or explosion. The heater does not

present a safety hazard when it is installed, operated and maintained

in accordance with these instructions.

2.0

The OK3 heater has two U-shaped metal sheath heating

elements factory interconnected in series or parallel depending on

voltage. Never change heaters which have been factory series

connected to a parallel connection.

3.0

Minimum space clearances from combustibles, when

heaters are horizontally mounted and installed, as listed in Table 1

following.

From nearest wall

600 mm (24”)

From the ceiling

INSTALLATION

The system designer is responsible for

the safety of this equipment and

adequate back-up controls and safety

devices must be installed. Failure to

comply could result in personal injury

and/or property damage.

Heaters must be wired by qualified

personnel in compliance with local

codes.

5.0

Verify that the nameplate voltage and wattage are suitable

for use on the available electrical power supply. Do not connect

the heater to an electrical supply voltage other than shown on the

product label.

Insulation contamination or moisture

accumulation can cause fault to the

element sheath generating arcing and

releasing molten metal. Install proper

ground fault protection to prevent

personal injury and/or property

damage.

6.0

The connection box volume is 3100 cm³(190 in³).

7.0

Supply conductors to the heater must be suitable for

110°C(230°C). The ground wire from the supply shall be connected

to the grounding connection located in the connection box.

8.0

The connection box has eight dual knockouts, ½" or ¾"

and two dual knockouts ¾" or 1". The standard Type 1 enclosure

is suitable for dry, indoor locations only in non-corrosive

environments.

9.0

For short circuit protection, heaters must be installed with

proper fast acting fuses or breakers as close as possible to the

ratings indicated on the nameplates, in compliance with the local

electrical codes.

4.0

To facilitate mounting, the heater has four ¼"-20 mounting

holes located at each top corner of the housing. Either chain

mounting (use eye bolts) or bolting to a non-combustible sliding

support (slotted holes) is adequate provided that the spacing

instructions as given in 3.0 are followed. Chain mounting is preferred

since rigidly mounted heaters are susceptible to warping.

FIG. 1 – MOUNTING CLEARANCES

MI102 REV.7.01 Page 1 of 8

1.0 INITIAL INSPECTION
1.1 Upon receipt from the carrier, inspect the heater for concealed

damage and report any damage found to the shipping company

immediately.

1.2 Verify that the nameplate voltage, phase and wattage are as

ordered and are suitable for use on the electrical power supply

available. DO NOT CONNECT THE GX UNIT HEATER TO AN

ELECTRICAL SUPPLY VOLTAGE OTHER THAN THAT SHOWN

ON THE PRODUCT NAMEPLATE.

1.3 The GX unit heater is CSA approved for operation in

nonhazardous areas only. Ensure that no hazardous conditions

exist before energizing the heater.
2.0 MOUNTING METHODS
2.1 Install the heater not less than 13cm (5”) from the wall, 15cm

(6”) from the ceiling and 244cm (8’) from the floor or grade.

2.2 The GX unit heater is CSA approved to operate with vertical

down flow or horizontal air flow discharge.

2.3 Select the appropriate air discharge direction for the application.

If horizontal, refer to Fig. 1 or Fig. 2 and if vertical down flow, refer

to Fig. 3.
NOTE THE FOLLOWING:
2.3.1 The GX heater weighs approximately 130 lbs.(59 kg). The

building support must be sufficiently strong to carry the weight.

2.3.2 All studs, bolts, nuts and other fasteners shall be secured

so that there is no possibility of loosening over prolonged periods.

These must be inspected at regular intervals and retightened when

necessary.

3.0 ELECTRICAL CONNECTIONS
3.1 Verify that the heater nameplate voltage and supply voltage

are the same (see paragraph 1.2).

3.2 Select the proper electrical conductor sizes. Conductor ratings

are listed in the electrical code.

3.3 Select a conduit style and conduit entrance fitting suitable for

EEMAC 12 (dust tight and drip tight - indoor) applications. This is

important since contamination of the control cabinet interior could

significantly reduce the operating life of the control components.

3.4 Remove the cabinet door to facilitate electrical access and

connection.

3.5 The control cabinet of the GX unit heater is constructed to

EEMAC 12 standards and as such, we are not permitted to supply

knockouts. After selection of the conductor and conduit entrance

sizes, punch the appropriate hole into the control cabinet. We

recommend the hatched area indicated in Fig. 4 be used for ease

of internal electrical connection.

3.6 The GX unit heater is completely prewired internally. Connect

the power conductors and any control conductors to the terminals

as illustrated on the wiring diagram fastened inside the control

cabinet door. Also refer to Fig. 5 for typical wiring.

INSTALLATION AND OPERATING INSTRUCTIONS

INSTRUCTIONS D’INSTALLATION ET D’OPÉRATION

TYPE GX UNIT HEATERS

AÉROTHERMES ULTRA-ROBUSTES MODÈLE GX

1.0 INSPECTION INITIAL
1.1 Sur réception de votre marchandise via le transporteur, vérifiez

si l’appareil est endommagé et rapoortez immédiatement tout

dommage visible à la compagnie de transport.

1.2 Vérifiez les caractéristiques de la plaque signalétique. Les

caractéristiques: tension, phase, et puissance, doivent être

identiques à celles de votre commande d’achat. NE JAMAIS

RACCORDER UN APPAREIL À UNE SOURCE D’ALIMENTATION

DIFFÉRENTE DE CELLE MONTRÉE SUR LA PLAQUE

SIGNALÉTIQUE.

1.3 L’appareil GX est approuvé CSA pour utilisation dans des

endroits non-dangereux seulement. Assurez-vous qu’il n’y a

aucune condition de danger avant d’opérer l’appareil.
2.0 MÉTHODES DE MONTAGES
2.1 Ne pas installer la chaufferette à moins de 13cm (5”) du mur,

15cm (6”) du plafond et 244cm (8’) du plancher ou sol.

2.2 L’appareil GX est approuvé CSA pour opération à débit d’air

horizontal ou vertical.

2.3 Sélectionnez la direction appropriée pour l’application. Pour un

débit horizontal, voir Fig. 1 ou Fig. 2 et pour un débit vertical, voir Fig. 3.
INFORMATIONS IMPORTANTES:
2.3.1 L’appareil GX pèse approximativement 130 lbs.(59 kg).

Le support fixé à la bâtisse doit être suffisamment robuste pour

soutenir un tel poids.

2.3.2 Tous les êcroux, rondelles, boulons devront être serrés

fermement afin de ne pas se déserrés même sur de longues

périodes d’opération.
3.0 CONNEXIONS ÉLECTRIQUES
3.1 Vérifiez la tension d’alimentation et la tension indiquée sur la

plaque signalétique (voir paragraphe 1.2).

3.2 Utilisez les conducteurs électriques de calibre approprié (Code

Électrique Canadien).

3.3 Utilisez un conduit et un raccord électrique de type 12 (à

l’épreuve des poussères et égouttures - intérieur). Ceci est très

important, car toute infiltration contaminante à l’intérieur du

panneau de contrôle pourrait réduire de façon très importante la

vie des composants.

3.4 Retriez la porte du boîtier de contrôle pour faciliter le

raccordement électrique.

3.5 Le boIitier de contrôle de l’appareil GX est fabriqué selon les

standards EEMAC 12. Aussi, il ne nous est pas permis d’y prévoir

des débouchures. Après la sélection du calibre des conduits et des

conducteurs, perforez un tour adéquat dans le boîtier de contrôle.
