Bryant EVOLUTION 987MA Product Data

987MA
EVOLUTIONR MODULATING
4--WAY MULTIPOSE, VARIABLE SPEED
CONDENSING GAS FURNACE, SERIES A

Product Data

A11264

The 987MA Multipoise Variable--Speed Condensing Gas Furnace
features the modulating EvolutionR System. The Perfect HeatR
Technology modulating gas system is at the heart of the comfort
provided by this furnace, along with the variable--speed ECM
blower motor, and variable--speed inducer motor. With an Annual
Fuel Utilization Efficiency (AFUE) of 97%, the Evolution
modulating gas furnace provides exceptional savings as well. This
Evolution Gas Furnace also features 4--way multipoise installation
flexibility, and is available in four model sizes. The 987MA can be
vented for direct vent/two--pipe, ventilated combustion air, or
single pipe applications. A Bryant Evolution Control and
Evolution Air Conditioner or Heat Pump, can be used to form a
complete Evolution System. All units meet California Air Quality
Management District emission requirements. All sizes are design
certified in Canada.

1. Nominal 350 CFM/ton cooling airflow is delivered with SW1-5 and SW4-2 set to OFF.

Set SW1-5 to ON for nominal 400 CFM/ton (+15% airflow).
Set SW4-3 to ON for nominal 325 CFM/ton (-7% airflow).
Set both SW1-5 and SW4-3 to ON for nominal 370 CFM/ton (+7% airflow).

2. Maximum cooling airflow is achieved when switches SW3-1, SW3-2, SW3-3 and SW1-5 are set to ON, and SW4-3 is set to OFF.

3. All heating CFM's are when low/medium heat rise adjustment switch (SW1-3) and comfort/efficiency adjustment switch (SW1-4) are both set to OFF.

4. Ductwork must be sized for high-heating CFM within the operational range of E.S.P. Operation within the blank areas of the chart is not recommended

because high-heat operation will be above 1.0 E.S.P.

5. All airflows on 21" (533 mm) casing size furnaces are 5% less on side return only installations.)

6. Side returns for 24.5" (622 mm) casing sizes require two sides, or side and bottom, to allow sufficient airflow at the return of the furnace.

Venting System Length Calculations

The maximum length for each vent pipe (inlet or exhaust) equals the Maximum Equivalent Vent Length (MEVL) from Table 1 or Table 3
minus the number of elbows multiplied by the deduction for each elbow in Table 2.

Standard vent terminations and concentric vent terminations count for zero deductions.

Example

A direct--vent 60,000 Btuh furnace installed at 2100 ft. (640 m) with 2--in.(51 mm) Vent piping. Venting system includes, FOR EACH
PIPE, (3) 90_ long radius elbows, (2) 45_ long radius elbows and a concentric vent kit.

Maximum Equivalent Vent Length = 127 ft. (From Table 1)

Deduct (3) 90 long radius 3 x 3 ft. = - 9 ft. (From Table 2)
Deduct (2) 45 long radius 2 x 1.5 ft. = - 3 ft. (From Table 2)

Maximum Vent Length = 115 ft. For EACH vent or inlet pipe

Notes:

1. 3 --- and 4 ---in. Vent pipe systems require long radius elbows.

2. Vent sizing for Canadian installations over 4500 ft. (1370 M) above sea level are subject to acceptance by the local authorities having jurisdiction.

3. NA --- Not allowed; pressure switch will not close, or flame disturbance may result.

4. Do not use pipe size greater than those specified in table or incomplete combustion, flame disturbance, or flame sense lockout may occur.

5. Size both the combustion ---air and vent pipe independently, then use the larger diameter for both pipes.

6. Assume the two 45_ elbows equal one 90_ elbow. Wide radius elbows are desirable and may be required in some cases.

7. Elbows and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.

8. The minimum pipe len gth is 5 ft. (1.5 M) for al l applications.

9. Use 3 - --in. (76 mm) diameter vent ter mination kit for installations requiring 4 ---in . (102 mm) diameter pipe.

RETURN AIR TEMPERATURE

This furnace is designed for continuous return--air minimum temperature of 60_F(15_C) db or intermittent operation down to 55_F(13_C)
db such as when used with a night setback thermometer. Return--air temperature must not exceed 80_F(27_C) db. Failure to follow these
return air limits may affect reliability of heat exchangers, motors and controls.

Concentric Vent Kit

A concentric vent kit allows vent and combustion--air pipes to
terminate through a single exit in a roof or side wall. One pipe
runs inside the other allowing venting through the inner pipe and
combustion air to be drawn in through the outer pipe.

Downflow Subbase

One base fits all furnace sizes. The base is designed to be installed
between the furnace and a combustible floor when no coil box is
used or when a coil box other than a Bryant cased coil is used. It is
CSA design certified for use with Bryant branded furnaces when
installed in downflow applications.
