be inadvertently turned on. Failure to turn off

gas or disconnect power before servicing could

result in death or serious injury.

• Follow installation instructions CAREFULLY to

a

void creating unsafe conditions. All wiring

should be done and checked by a qualified

electrician, using copper wire only. All external

wiring must conform to applicable local codes

and to the latest edition of the National

Electrical Code ANSI/NFPA No. 70.

• All gas connections shoul

d be made and leak-

tested by a suitably qualified individual, per

instructions in this manual. Also follow

procedures listed in “Gas Equipment Start-Up,”

p. 31.

• Use only the fuel for which the unit heater is

desi

gned (see rating plate). Using LP gas in a

heater that requires natural gas, or vice versa,

will create the risk of gas leaks, carbon

monoxide poisoning and explosion.

Important: Do not attempt to convert the heater

f

or use with a fuel other than the one

intended. Such conversion is

dangerous, as it could create the risks

listed previously.

• Make certain that the power source conforms to

t

he electrical requirements of the heater.

• All field-installed wiring must be completed by

q

ualified personnel. All field-installed wiring

must comply with NEC and applicable local

codes. Failure to follow this instruction could

result in death or serious injuries.

• Special attention must be given to any

gr

ounding information pertaining to this heater.

To prevent the risk of electrocution, the heater

must be securely and adequately grounded. This

should be accomplished by connecting a

grounded conductor between the service panel

and the heater. To ensure a proper ground, the

grounding means must be tested by a qualified

electrician.

• Do not insert fingers or foreign objects into the

heater or its air mo

ving device. Do not block or

tamper with the heater in any manner while in

operation or just after it has been turned off, as

some parts may be hot enough to cause injury.

• This heater is intended f

or general heating

applications ONLY. It must NOT be used in

potentially dangerous locations such as

flammable, explosive, chemical-laden or wet

atmospheres.

• In cases in which property damage may result

fr

om malfunction of the heater, a backup system

or a temperature sensitive alarm should be used.

• When connecting to existing gas lines be

sure to

valve off the gas supply ahead of connection

point. To avoid explosion or possible fire, always

purge all residual gas from piping before cutting

into existing line or removing threaded fittings.

Failure to remove all gas vapors could result in

death or serious injury or equipment or property-

only-damage.

Unless otherwise specified, the following conversions

may be used for calculating SI unit measurements:

Identification of Parts

1 foot = 0.305 m 1 inch water column = 0.249 kPa

1 inch = 25.4 mm 1 meter/second = FPM ÷ 196.8

1 psig = 6.894 kPa 1 liter/second = CFM x 0.472

1 pound = 0.453 kg 1000 Btu per hour = 0.293 kW

1 gallon = 3.785 L 1000 Btu/Cu. Ft. = 37.5 MJ/m
