SECTION 1: 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 Weather-Rite
LLC.
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 49,
Section 17 .2. For maximum temperature rise, See
Page 66, Table 18.
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. Weather-Rite LLC will not be held
responsible for any damages that may occur from
outdoor storage.
