II. GENERAL SAFETY REQUIREMENTS
Open all disconnect switches
before installing the unit. 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 may result in personal injury or
death from electrical shock.
Failure to comply with the general
requirements may result in extensive property
damage, severe personal injury or death.
Never service any component
without fi rst disconnecting all electrical and gas
supplies to the unit or severe personal injury or
death may occur.
1. Installation must be made in accordance with local
codes, or in absence of local codes, with ANSI
Standard Z223.1-1996 (N.F.P.A. No 54) “National
Fuel Gas Code”, or the latest edition of. All ANSI and
NFPA Standards referred to in these installation
instructions are the ones that were applicable at the
time the design of this appliance was certifi ed. The
ANSI Standards are available from the American
Gas Association, 1515 Wilson Boulevard, Arlington,
Virginia 22209. The NFPA Standards are available
from the National Fire Protection Association,
Batterymarch Park, Quincy, Massachusetts 02269.
The heaters are designed for use in airplane hangers
when installed in accordance with ANSI/NFPA No.
409 and in public garages when installed in
accordance with the NFPA No. 88A and NFPA No.
88B.
2. If installed in Canada, the installation must conform
with local building codes, or in the absence of local
building codes, with the current CGA-B149.1 or
B149.2 “Installation Codes for Gas Bur ning
Appliances and Equipment”. These indoor duct
furnaces have been designed for and certified to
comply with CGA 2.6.
3. No alterations are to be made on this equipment.
The duct furnace section of these make-up air units are
certifi ed by the American Gas Association for use with
natural and LP (propane) gases!
Do not alter the duct furnace in any
way or damage to the unit, severe personal injury
or death will occur.
4. Make certain that the power sources conform to the
requirements of the heater.
5. 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 gas connections should be made
and leak-tested by a suitably qualifi ed individual, per
instructions in this manual.
6. Use only the fuel for which the heater is designed
(see nameplate). 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 could create
unsafe conditions that result in death, serious
injury or substantial property damage.
7. Make cer tain that power source conforms to
electrical requirements of heater. Disconnect
power before installing or servicing heater. If power
disconnect is out of sight, lock it in open position and
tag it to prevent unexpected application of power.
Failure to do so could result in fatal electric shock.
Do not depend upon a thermostat
or other switch as the 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.
8. 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
from the service panel to the conduit box of the heater.
To ensure proper ground, the grounding means must
be tested by qualifi ed fi eld electrician.
9. Do not insert fingers 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.
10. 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.
