ARCHITECT’S AND ENGINEER’S SPECIFICATIONS*

The heating equipment shall include an electric automatic

fan forced air heater suitable for large area heating, as

manufactured by QMark, A Marley Engineered Products

Brand, Bennettsville, SC. The heater shall be designed

for wall mounting, recess or surface. Heaters shall be UL

listed.

HEATER ASSEMBLY: The heater assembly which fits

into the back box shall consist of a fan panel upon which

is mounted all of the operational parts of the heater.

HEATING ELEMENT: The heating element shall be of

the non-glowing design consisting of an 80/20 nickel-

chromium resistance wire enclosed in a steel sheath to

which plate fins are copper brazed. It shall be warranted

for 5 years.

FAN AND FAN MOTOR: The fan shall be five-bladed

aluminum. The fan motor shall be totally enclosed.

FAN DELAY SWITCH: Fan control shall be of bi-

metallic, snap-action type and shall activate fan after

heating element reaches operating temperature. The

fan shall continue to operate after the thermostat is

satisfied and until the heating element is cool.

THERMOSTAT: The tamper-proof thermostat shall be of

the bi-metallic, snap-action type with enclosed contacts.

It shall be completely concealed behind the front cover to

become tamper proof.

THERMAL CUTOUT: A thermal cutout shall be built into

the system to shut off the heater in the event of over-

heating.

DISCONNECT SWITCH: A double-pole single throw

disconnect switch shall be mounted on the back box for

positive disconnect of power supply. It will be completely

concealed behind the front grid panel.

PNEUMATIC/ELECTRIC SWITCH: An optional

pneumatic/electric switch shall be available for use with

energy management systems employing pneumatic

pressure devices for controlling comfort levels and set-

back operations.

LOW VOLTAGE RELAYS: Normally open 24-volt and

120-volt low voltage holding coil relays shall be available

as optional equipment to control 208, 240, or 277 volt

heaters in conjunction with central energy control sys-

tems. The built-in thermostat can then be used as one of

the thermostats in an automatic night set back operation.

BACK BOX: The back box shall be designed for duty as

a recessed rough-in box in either masonry or frame

installations and is also used with the surface mounting

frame in surface mounting installations. The back box

shall be 20-gauge galvanized steel and shall contain

knockouts through which power leads are brought.

FRONT PANEL: The front panel shall be of the bar grille

type and shall be constructed of 16-gauge cold-rolled

steel, welded into a uniform grille and finished in baked

enamel to direct the warmed air toward the floor. The

front grille shall be surrounded by a decorative satin-

finish aluminum "picture" frame.

THREE PIECE DESIGN: The heater shall be made of a

back box, a heater assembly, and a front panel.
