Convection Air Heater for Hazardous Locations  
NOTICE: Carefully remove heater from carton and check for  
shipping damage. Any damage claims should be entered  
immediately with the carrier.  
GENERAL  
Type CVEP Convection Heaters are designed for use in Class  
I, Div I hazardous environments. Units without control options  
are suitable for areas classified as Groups B, C & D. Units with  
built-in controls can be supplied for groups C and D or B, C and  
D. Refer to classification stamped on heater nameplate.  
have the same explosion-proof rating as heater.  
5. Do not install one unit above the other.  
6. Units are mounted a minimum of 8” above the floor.  
7. Heaters are mounted on wall in a horizontal position with termi-  
nal end at right. Never recess heater into wall.  
8. NOTE: Article 500 of the National Electric Code (NEC) out-  
lines requirements for installation of electrical equipment in haz-  
ardous (Classified) locations.  
FIRE/EXPLOSION HAZARD. To prevent ignition of haz-  
ardous atmospheres, this heater should not be installed in  
areas where vapors or gases having an ignition tempera-  
ture less than 280˚C (536˚F)(T2A) at 1.8kW, 3.6kW, 4.5kW,  
7.6kW, 9.0kW or 180˚C (356˚F)(T3A) at 1.6kW, 3.2kW,  
4.0kW are present.  
9. All unit electrical installation fittings, conduit, wiring and seals  
must meet NEC and local codes for hazardous locations. External  
line fusing or circuit breaker protection is required.  
10. Failure to understand and follow these installation instructions  
and the “WARNING” notes contained therein may result in  
severe personal injury, death or substantial property damage.  
These heaters must not be operated in ambient tempera-  
tures exceeding 40˚C (104˚F).  
1. Connect air heaters to the same line voltage as on heater nameplate.  
2. Heaters can be mounted individually end to end.  
ELECTRIC SHOCK HAZARD. Any installation  
involving electric heaters must be performed by a  
qualified person and must be effectively grounded  
in accordance with the National Electrical Code to  
eliminate shock hazard.  
3. Heaters can be mounted directly on any type of surface masonry,  
concrete, block, plastered walls, metal framework, etc.-using  
appropriate hardware.  
4. All controls such as thermostat and contactor, when required must  
INSTALLATION  
5. Drill a pilot hole in wall mounting surface at each mounting hole  
location. Use a convenient small size drill.  
6. Drill the mounting holes in accordance with size in Table 1. Insert  
anchors where applicable.  
ELECTRIC SHOCK HAZARD. Disconnect all power  
before installing or servicing heater. Failure to do so  
could result in personal injury or property damage.  
Heater must be installed by a qualified person in accor-  
dance with the National Electrical Code, NFPA 70.  
7. Fasten rear panel to wall with screws noted in Table 1.  
8. Replace front panel and screws.  
1. Remove front panel by removing screws.  
2. Locate desired heater position on wall.  
3. Locate mounting holes for rear panel. Rear panel must be a mini-  
mum of 8” from the floor.  
FIRE HAZARD. Never operate heater with front panel  
off. Adequate air flow across heating elements  
requires the front panel to be in place. The heating  
elements could overheat causing equipment damage  
or personal injury.  
4. Refer to Figure 1A, 1B or 1C for mounting hole layout for each  
cabinet size.

WIRING  
4. Remove cover of conduit box for connections. Use either opening  
and plug the other with the plug provided.  
5. In single phase units the heaters must be wired in parallel, com-  
bining L1 to L1, L2 to L2 and for 3 phase unit, L3 to L3.  
6. Re-assemble cover with a minimum of 7 turns.  
ELECTRIC SHOCK HAZARD. Any installation  
involving electric heaters must be performed by a  
qualified person and must be effectively grounded  
in accordance with the National Electrical Code to  
eliminate shock hazard.  
1. All wiring should be done in accordance with local codes and  
the National Electrical Code by a qualified person as defined in  
the NEC.  
FIRE/EXPLOSION HAZARD.(Group B atmospheres)  
To prevent ignition of Group B atmospheres, conduit  
runs must not exceed 3/4” in size and all conduit  
runs 1/2” size and larger must have a sealing fitting  
connected within 2”, 6” or 18” of the terminal enclo-  
sure depending on the exact model. For correct  
placement, refer to data located on the enclosure  
label.  
CAUTION: Use copper conductors only.  
2. Rough-in-line-wiring to unit in manner approved for hazardous  
locations. (See warning below.)  
3. Wire per diagrams 1 through 6 based on the rating and control  
options listed in table 2. Refer to table 3 for amperage specifications.

OPERATION  
property damage, back-up controls are essential.  
1. Do not operate heater at voltages in excess of that stamped on  
the heater since excess voltage will shorten heater life and  
cause high element temperatures which may exceed allowable  
temperatures of operation in a hazardous atmosphere.  
The system designer is responsible for the safety  
of this equipment and should install adequate  
back-up controls and safety devices with their  
electric heating equipment. Where the conse-  
quences of failure could result in personal injury or

MAINTENANCE  
1. Before activating for next heating season, vacuum or use com-  
pressed air to remove accumulated dust or lint, which otherwise  
may restrict proper air flow.  
ELECTRIC SHOCK HAZARD. Disconnect all power  
before installing or servicing heater. Failure to do  
so could result in personal injury or property dam-  
age. Heater must be installed by a qualified per-  
son in accordance with the National Electrical  
Code, NFPA 70.  
2. Periodically check all electrical connections and retighten to avoid  
electrical wiring difficulties.  
3. Check to ensure terminal cover is tightly closed, before energiz-
