GENERAL SAFETY INFORMATION

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 the risk of gas 
leaks, carbon monoxide poisoning and explosion.

 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 listed previously.

Make certain that the power source conforms to the 
electrical requirements of the heater.

 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.

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 grounded conductor between the service 
panel and the heater. To ensure a proper ground, the 
grounding means must be tested by a qualifi ed electrician.

Do not insert fi ngers or foreign objects into the 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 fl ammable, explosive, chemical-laden 
or wet atmospheres.

In cases in which property damage may result from 
malfunction of the heater, a backup system or a 
temperature sensitive alarm should be used.

 The open end of piping systems being 

purged shall not discharge into areas where there are 
sources of ignition or into confi ned spaces UNLESS 
precautions are taken as follows: (1) by ventilation of 
the space, (2) control of purging rate, (3) elimination 
of all hazardous conditions. All precautions must be 
taken to perform this operation in a safe manner!

Unless otherwise specifi ed, the following conversions 
may be used for calculating SI unit measurements:
1 foot = 0.305 m
1 inch = 25.4 mm
1 psig = 6.894 kPa
1 pound = 0.453 kg
1 gallon = 3.785 L
1 cubic foot = 0.028 m

 Failure to comply with the general 

safety information may result in extensive 
property damage, severe personal injury or death.

 This product must be installed by 

a licensed plumber or gas fi tter when installed 
within the Commonwealth of Massachusetts.

Installation must be made  in  accordance with 
local codes, or in absence of local codes, with the 
latest edition of 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 the American National 
Standards Institute, Inc., www.ansi.org. 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 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 certifi ed to comply with CSA 2.6. Also see sections 
on installation in AIRCRAFT HANGARS and PUBLIC 
GARAGES.

 Do not alter the unit heater in any 

way or damage to the unit and/or severe personal 
injury or death may occur

!

 Disconnect all power and gas 

supplies before installing or servicing the heater. 
If the power disconnect is out of sight, lock 
it in the open position and tag it to prevent 
unexpected application of power. Failure to do 
so could result in fatal electric shock, or severe 
personal injury.

 Ensure that all power sources 

conform to

 

the requirements of the unit heater or 

damage to the unit will result!

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 qualifi ed individual, per instructions 
in this manual. Also follow procedures listed on the “Gas 
Equipment Start-Up Sheet” located in this manual.
