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 certifi ed. 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 external wiring must
conform to applicable current local codes, and to the
latest edition of the National Electric Code ANSI/NFPA
No. 70. In Canada, all external wiring must conform to
the Canadian Electric Code, Part 1 CSA Standard C22.1.
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”

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.
Do not attach ductwork to this product or use it as a
makeup air heater. Such usage voids the warranty and
will create unsafe operation.
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:
