Bryant 585B User Manual

Model 585B Gas/Electric Units are fully self-contained, single-packaged combination heating/cooling horizontal­discharge units.
These packaged units are equipped with an energy-saving RELITE-type electric spark ignition pilot that saves gas by operating only when the room thermostat “calls for heat ing.” Natural gas controls are standard. For propane opera tion, conversion kit P/N 301625-703 must be field-installed.
Model 585B units have two A.G.A.-certified heating input ratings. See Table I.
These units are designed for outdoor installation either on a rooftop or at ground level on a slab. The cooling section is factory-charged and sealed, minimizing installation time. Installation is easy—connect gas supply, air ducts, conden sate drain, high- and low-voltage wiring, and install the air filter.
NOTE: An optional condenser coil grille is available for field
installation. See Figure 1. A full line of rooftop system accessories are available for
field installation. These accessories include plenums with
factory-supplied high-capacity filter and outside air intake hood, unitized curbs, economizers (both downflow and horizontal), barometric relief dampers, concentric diffuser box assemblies, flexible duct packages, and high-capacity filter racks with filters. When installing these accessories, see Installation Instructions packaged with them.

fmportant—Read Before Installing

1. Check all local or other applicable codes for information concerning proximity to property lines, height above roof, obstructions, etc.
2. Make certain power supply available (volts, hertz, and phase) corresponds to that specified on unit rating plate.
3. Check electrical supply provided by utility to be sure that service capacity is sufficient to handle load imposed by this unit.
4. Locate the unit where the vent cap is a minimum of 4 feet from openable windows or doors.
5. The installation must conform with local building codes
or, in the absence of local codes, with the National Fuel Gas Code ANSI Z223.1.

24 inches. Select a location where rain, ice, and snow will not fall from an overhang and damage the unit top or fan blade, or flood the unit.
There is no minimum clearance requirement for the bottom of the unit; therefore, combustible materials can be used for supports.

D. Base Rails

The base rails are easily removed for a lower profile installa tion or a better fit to angle iron frames used in some rooftop installations. To remove the base rails, simply remove the screws on either end of the rails.
NOTE: The base rails must not be removed when installing
the accessory unitized curb and plenum.

E. Condensate Drain

The unit is designed to dispose of condensate water through a 3/4-inch FPT connection on the drain pan. See Figure 2 for location. It is recommended that a trap be installed in the condensate drain line to avoid improper drainage. See Figure 5. The trap should be as close to the coil as possible. Make sure that the top of the trap is at least 2 inches lower than the drain pan connection to prevent the drainpan from overflowing.
Prime the trap with water and check the condensate line for leaks.
If the installation requires draining the condensate away from the roof or the building, connect a minimum of 7/8-inch OD copper tubing, 3/4-inch galvanized pipe, or 7/8-inch plastic pipe, and pitch downward at a slope of at least 1 inch in every 10 feet of horizontal run.
CAUTION: Do not imdtTsizf conden.sate drain connection.
Consult local codes for additional restrictions and/or precau tions.

II. VENTING

NOTE: The vent cap assembly is shipped in the blower com
partment with sizes 018050 and 024050. Remove the blower access door to locate the assembly. This assembly is shipped in the control compartment with all other sizes. Remove the control access door to locate the assembly. See Figure 2 for the location of these access doors.
CAUTION: The veniin g system has been designed to ensure
proper venting, fhe vent cap assembly niii.st be installed
only as indicated in this section of the unit Installation In structions.
NOTE: Screw holes in the vent stack extension and the vent
cap are not symmetrically located to ensure proper orienta tion when installing these components.
Refer to Figure 6 and install the vent cap assembly as fol lows:
1. Place gasket and vent stack extension through hole in combustion air duct and orient screw holes in base of vent stack extension with holes in unit top.
2. Secure gasket and vent stack extention to unit top with screws provided.
3. Place vent cap onto vent stack extension and orient screw holes in vent cap with holes in extension.
4. Secure vent cap in place with screws provided.
5. Form flat wire screen provided into circular shape around protruding lip of combustion air duct.
6. Bend wire ends through holes of screen mesh to secure
screen in place.

III. GAS PIPING
A separate gas supply line should be installed to run directly from meter to heating section. Check the local utility for recommendations concerning existing lines. Choose a supply pipe large enough to keep pressure loss as low as practical. Never use pipe smaller than gas connection to heating sec tion. Observe local codes for all gas pipe installations. Refer to the national codes indicated on the first page of the in structions in the absence of local building codes. The fol lowing are pertinent recommendations:
1. Avoid low spots in long runs of pipe. It is best to grade all pipe 1/4 inch in every 15 feet to prevent traps. All horizontal runs should grade downward to risers. Risers should be used to connect to heating section and to meter.
2. Install drip leg in riser leading to heating section. Drip leg will function as trap for dirt and condensate. Install drip legs where condensate will not freeze.
3. Install external manual shut-off valve in gas supply
pipe near heating section.
CAUTION: I 'n>lal)lo ipperaiioii may (Hcur. parriiailarly

4. Where local codes permit, we recommend using flexible gas pipe to make connection between rigid, gas piping and unit gas valve to ensure proper alignment between manifold orifices and burners. Gas supply pipe enters unit through access hole provided. See Figure 2 for loca tion. Gas connection to unit is made to 1/2-inch FPT gas inlet on gas valve. See Figure 7.
5. Install ground joint union close to heating section be
tween gas valve and manual shut-off valve.
6. Support all piping with appropriate hangers, etc. Use minimum of one hanger in every 6 feet. For pipe size other than 1/2 inch, follow recommendations of the na tional codes.
7. Use joint compound (pipe dope) that is resistant to action of liquefied petroleum gases.
NOTE: Teflon tape is not recommended.
WARNING: Never use a match or other open flame when checking for gas leaks.
8. After all connections are made, use soap-and-water solu
tion to check for leaks (or method specified by local utility regulations) at all field installed and factory in stalled gas lines.
IV. DUCT CONNECTIONS Flanges are provided on the unit supply- and return-air
openings for duct connections. See Figure 2 for connection sizes and locations. See Figures 8, 9, and 10 for illustrations
of typical installations.
