GENERAL SAFETY INFORMATION
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 CSA Information Services, 1-800-
463-6727. The NFPA Standards are available from the
National Fire Protection Association, Batterymarch Park,
Quincy, MA 02269. These duct furnaces are designed for
use in airplane hangars when installed in accordance
with current ANSI/NFPA No. 409 and in public garages
when installed in accordance with current 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-B149.8
“Installation Codes for Propane Gas Burning Appliances
and Equipment”. These indoor duct furnaces 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 duct furnace 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.
Insure 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 qualifi ed electrician, using copper wire
only. All external wiring must conform to applicable local
codes, and to the latest edition of the National Electric
Code ANSI/NFPA No. 70. 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.
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, and
could create unsafe conditions that result in death,
serious personal injury or property damage.
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!
