Winter start kit
The winter start kit by Bryant extends the low ambient limit of
your rooftop to 25°F (–4°C). The kit bypasses the low pressure
switch, preventing nuisance tripping of the low pressure
switch. Other low ambient precautions may still be prudent.
Propane heating
Convert your gas heat rooftop from standard natural gas opera-
tion to propane using this field-installed kit.
High altitude heating
High altitudes have less oxygen, which means heat exchangers
need less fuel. The new gas orifices in this field-installed kit
make the necessary adjustment for high altitude applications.
They restore the optimal fuel to air mixture and maintain
healthy combustion at altitudes above 2000 ft (610m). Kits
may not be required in all areas.
Hinged access panels
Allows access to unit's major components with specifically
designed hinged access panels. Panels are: filter, control box,
fan motor, and compressor.
Flue discharge deflector
The flue discharge deflector is a useful accessory when flue gas
recirculation is a concern. By venting the flue discharge
upwards, the deflector minimizes the chance for a neighboring
unit to intake the flue exhaust.
Optional stainless steel heat exchanger
The stainless steel heat exchanger option provides the tubular
heat exchanger made out of a minimum 20 gage type 409 stain-
less steel for applications where the mixed air to the heat
exchanger is expected to drop below 45°F (7°C). Stainless steel
may be specified on applications where the presence of air-
borne contaminants require its use (applications such as paper
mills) or in areas with very high outdoor humidity that may
result in severe condensation in the heat exchanger during cool-
ing operation.
Flue discharge heat shield
The flue discharge heat shield keeps people from touching the
rooftop unit's potentially hot flue discharge. This is especially
useful for ground level applications, where more untrained
people could have access to the unit's exterior.
Alternate motors and drives
Some applications need larger horsepower motors, some need
more airflow, and some need both. Regardless of the case, your
Bryant expert has a factory-installed combination to meet your
application. A wide selection of motors and pulleys (drives) are
available, factory installed, to handle nearly any application.
Thru-the-base connections
Thru-the-base connections, available as either an accessory or
as a factory option, are necessary to ensure proper connection
and seal when routing wire and piping through the rooftop's
basepan and curb. These couplings eliminate roof penetration
and should be considered for gas lines, main power lines, as
well as control power.
