Make certain that the power source conforms to the electrical

requirements of the heater.

Special attention must be given to any grounding 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 ground 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 heater or its air

moving 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 for 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 from

malfunction of the heater, a back-up system or temperature

sensitive alarm should be used.

Unless otherwise speciﬁed, the following conversions may

be used for calculating SI unit measurements:

1 foot = 0.305 m

1 inch = 25.4 mm

1 gallon = 3.785 L

1 pound = 0.453 kg

1 psig = 6.894 kPa

1 cubic foot = 0.028m

General Safety Information

Installation must be made in accordance with local codes,

or in absence of local codes, with the latest edition of the

ANSI Standard Z223.1 (N.F.P.A. No. 54) National Fuel Gas

Code. All of the ANSI and NFPA Standards referred to in

these installation instructions are those that were applicable

at the time the design of this appliance was certified. The

ANSI Standards are available from CSA Information Services,

1-800-463-6727. The NFPA Standards are available from the

National Fire Protection Association, Batterymarch Park,

Quincy, MA 02269. These unit heaters are designed for

use in airplane hangars when installed in accordance with

ANSI/NFPA No. 409, and in public garages when installed in

accordance with NFPA No. 88A and NFPA No.88B.

If installed in Canada, the installation must conform with local

building codes, or in the absence of local building codes,

with CSA-B149.1 “Installation Codes for Natural Gas Burning

Appliances and Equipment” or CSA-B149.2 “Installation

Codes for Propane Gas Burning Appliances and Equipment.”

These unit heaters have been designed and certified to

comply with CSA 2.6. Also see sections on installation in

AIRCRAFT HANGARS and PUBLIC GARAGES.

Follow installation instructions CAREFULLY to avoid creating

unsafe conditions. All wiring should be done and checked

by a qualified electrician, using copper wire only. All gas

connections should be made and leak-tested by a suitably

qualified individual, per instructions in this manual. Also

follow procedures listed on “Gas Equipment Start-Up Sheet”

located in this manual.

Use only the fuel for which the heater is designed (see rating

plate). Using LP gas in a heater that requires natural gas, or

vice versa, will create risk of gas leaks, carbon monoxide

poisoning, and explosion.

1000 BTU/cu. ft. = 37.5 MJ/m3

1000 BTU per hour = 0.293 kW

1 inch water column = 0.249 kPa

1 litre/second = CFM x 0.472

1 meter/second = FPM ÷ 196.8

CAUTION

Ensure that all power sources conform to the requirements of

the unit heater, or damage to the unit will result!

WARNING

Failure to comply with general safety information may result in

extensive property damage, severe personal injury, or death.

WARNING

This product must be installed by a licensed plumber or gas ﬁt-

ter when installed within the Commonwealth of Massachusetts.

WARNING

Do not alter the unit heater in any way or damage to the unit

and/or severe personal injury or death may occur!

WARNING

Disconnect all power and gas supplies before installing or ser-

vicing the heater. If the power disconnect is out of sight, lock it

in the open position and tag it to prevent unexpected applica-

tion of power. Failure to do so could result in fatal electric shock,

or severe personal injury.

WARNING

Do not attempt to convert the heater for use with a fuel other

than the one intended. Such conversion is dangerous, as it will

create the risks previously listed.

WARNING

Do not depend upon a thermostat or other switch as sole means

of disconnecting power when installing or servicing heater.

Always disconnect power at main circuit breaker as described

above. Failure to do so could result in fatal electric shock.

CAUTION

The open end of piping systems being purged shall not dis-

charge into areas where there are sources of ignition or into

conﬁned spaces UNLESS precautions are taken as follows: (1)

by ventilation of the space, (2) control of the purging rate, (3)

elimination of all hazardous conditions. All precautions must be

taken to perform this operation in a safe manner!
