SECTION 1: B-SERIES AIR HANDLER SAFETY
1
SECTION 1: B-SERIES AIR HANDLER SAFETY
Your Safety is Important to Us!
This symbol is used throughout
the manual to notify you of
possible fire, electrical or burn
hazards. Please pay special
attention when reading and
following the warnings in these
sections.
Installation, service and, at a minimum, annual
inspection of air handlers must be done by a
contractor qualified in the installation and service of
gas-fired heating equipment.
Read this manual carefully before installation,
operation or service of this equipment.
This air handler is designed for heating non-
residential indoor spaces. Do not install in residential
spaces. These instructions, the layout drawing, local
codes and ordinances and applicable standards that
apply to gas piping, electrical wiring, ventilation, etc.
must be thoroughly understood before proceeding
with the installation.
Protective gear is to be worn during installation,
operation and service in accordance to the
Occupational Safety and Health Administration
(OSHA). Gear must be in accordance to NFPA 70E,
latest revision when working with electrical
components. Thin sheet metal parts have sharp
edges. To prevent injury, the use of work gloves is
recommended.
Before installation, check that the local distribution
conditions, nature of gas and pressure and
adjustment of the appliance are compatible.
The equipment must be applied and operated under
the general concepts of reasonable use and installed
using the best building practices.
This piece of equipment is not intended for use by
persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given
supervision or instruction concerning use of the
equipment by a person responsible for their safety.
Children should be supervised to ensure that they do
not play with the equipment.
For additional copies of the Installation, Operation
and Service Manual, please contact Bananza®.
Gas-fired equipment is not designed for use in
atmospheres containing flammable vapors or dust or
atmospheres containing chlorinated or halogenated
hydrocarbons. Recirculated room air may be
hazardous if containing flammable solids, liquids,
and gases; explosive materials; and/or substances
which may become toxic when exposed to heat (i.e.
refrigerants, aerosols, etc.).
1.1 Description of Operation
This air handler is a direct, gas-fired, fresh-air piece
of equipment. It is designed for indoor or outdoor
installation with fresh outdoor air delivered to the
burner. Air handlers are designed to operate in
temperatures as low as -30° F (-34° C). The air
handler is factory-tested to fire with natural gas or
LPG (check the air handler's rating plate for
information on the appropriate gas). The burner
flame will modulate to maintain the selected
discharge air temperature or room air temperature,
depending on the selected controls. See Page 52,
Section 17.2. For maximum temperature rise, See
Page 69, Table 19.
The air handler may be provided with several
different controls and options to meet various
application requirements. Be sure to read this entire
manual before installation and start-up.
1.2 Inspection and Setup
The air handler is shipped fully assembled. The air
handler was inspected and operated prior to
shipment. Immediately upon receipt of the air
handler, check the fuel and electrical characteristics
of the air handler and verify that they match the fuel
and electrical supply available. Verify that the
specifications on the air handler rating plate match
the order. Check the air handler for any damage that
may have occurred during shipment. If any damage
is found, file a claim with the transporting agency. Do
not refuse shipment. Check the installation location
to ensure proper clearances to combustibles. See
Page 5, Section 3.1.
Any small options which do not come attached to the
air handler (i.e. remote panel) will be found inside the
air handler.
Larger accessories (i.e. legs, stand, filter section,
inlet hood) may either ship with the air handler or
separately. Check the bill of lading for information.
If the air handler must be temporarily stored (i.e. job
site is not ready for installation of the air handler), the
air handler should be set on 4" x 4" (10 cm x 10 cm)
pieces of timber on the ground in a protected area.
Cover the air handler to protect it from the
environment. Bananza® will not be held responsible
for any damages that may occur from outdoor
storage.

1.3 Safety Labels and Their Placement
Product safety signs or labels should be replaced by
product user if they are no longer legible. Please
contact Bananza® or your Bananza® independent
distributor to obtain replacement signs or labels.
1.4 California Proposition 65
In accordance with California Proposition 65 require-
ments, a warning label must be placed in a highly
visible location on the outside of the equipment (i.e.,
near equipment's serial plate). To order additional
labels, please contact Bananza® or your Bananza®
independent distributor.

SECTION 2: INSTALLER RESPONSIBILITY
3
SECTION 2: INSTALLER RESPONSIBILITY
The installer is responsible for the following:
• To install and commission the air handler, as well
as the gas and electrical supplies, in accordance
with applicable specifications and codes.
Bananza
®
recommends the installer contact a
local building inspector or Fire Marshal for
guidance.
• To use the information given in a layout drawing
and in the manual together with the cited codes
and regulations to perform the installation.
• To install the heater in accordance with the
clearances to combustibles.
• To furnish all needed materials not furnished as
standard equipment.
• To plan location of supports.
• To provide access to air handler for servicing.
• To provide the owner with a copy of this
Installation, Operation and Service Manual.
• To never use heater as support for a ladder or
other access equipment and never hang or
suspend anything from heater.
• To ensure there is adequate air circulation around
the air handler and to supply air for combustion,
ventilation and distribution in accordance with
local codes.
• To assemble or install any accessories or
associated duct work using best building
practices.
• To properly size supports and hanging materials.
• To ensure heater is placed in an approved
application.
2.1 Wall Tag
A laminated wall tag is available for the heater as a
permanent reminder of the safety instructions and
the importance of the required clearances to
combustibles. Please contact Bananza® or your
Bananza® independent distributor to obtain the wall
tag. Affix the tag on a wall near the heater (e.g.
thermostat or control system).
A copy of the wall tag (P/N 91040118) is illustrated on
the back cover. For an immediate solution, you may
affix this copy on the wall near the heater.
Know your model number and installed configuration.
Model number and installed configuration are found
on the rating plate and in the Installation, Operation
and Service Manual.
2.2 Corrosive Chemicals
Bananza® cannot be responsible for ensuring that all
appropriate safety measures are undertaken prior to
installation; this is entirely the responsibility of the
installer. It is essential that the contractor, the sub-
contractor, or the owner identifies the presence of
combustible materials, corrosive chemicals or
halogenated hydrocarbons* anywhere in the
premises.
* Halogenated Hydrocarbons are a family of chemical
compounds characterized by the presence of halogen elements
(fluorine, chlorine, bromine, etc.). These compounds are
frequently used in refrigerants, cleaning agents, solvents, etc. If
these compounds enter the air supply of the burner, the life span
of the air handler components will be greatly reduced. The loca-
tion of the outside air supply must be carefully chosen to supply
outside air, free of these compounds, to the burners whenever
the presence of these compounds is suspect. Warranty will be
invalid if the air handler is exposed to halogenated hydrocar-
bons.
WARNING
Explosion Hazard
Equipment must have access to
uncontaminated air at all times.
Failure to follow these instructions can result
in death, injury or property damage.
CAUTION
Product Damage Hazard
Do not use equipment in area containing
corrosive chemicals.
Refer to appropriate Material Safety Data
Sheets (MSDS).
Failure to follow these instructions can result
in product damage.
