6-189.14

Selection Example Conditions (Blower Unit)

In the following example, select a unit heater to meet the

following conditions:

1. Heating output capacity = 156,000 Btu/Hr per design engineer

2. External Static Pressure = 0.2.

3. Internal Static Pressure = 0.0. No static producing accessories

are required

4. Heat exchanger and burner = Aluminized Steel

5. Gas Type = Propane

6. Gas Controls = Two stage Intermittent Pilot

7. Supply Voltage: 230V/60Hz/3Ph

8. Altitude: 1,000 feet

9. CFM = 2,400

Selection Example Solution (Blower Unit)

With the information listed above, the basic model, using the

information in this catalog and the Model Nomenclature shown on

page 32, can be selected as shown in the following example:

1. Determine the Model and Input Rating (MBH):

Using the Heating output capacity, the Furnace Input Rating is

determined from Table 13.1 The closest model to 156,000 Btu/Hr

output has an Btu/Hr Input rating of 200,000 Btu/Hr so the

Furnace Input Rating = 200. The corresponding model for a 200

size, blower, power vented unit heater is BDP. The model and

size are a BDP200.

2. Determination of Heat Exchanger/Burner/Drip Pan Material:

From item #4 in the example, the Heat Exchanger and

Burner required are aluminized steel. Thus, the Heat Exchanger

Material = A from the Model Nomenclature on page 32.

3. Determine the development sequence:

From item #6 in the example, the IPI results in the Development

Sequence = E from the Model Nomenclature on page 32.

4. Determine Power Code Required:

From page 16 we see that a unit requiring a static of 0.2 and a

cfm of 2400 requires a 1/3 horsepower motor with a -102 drive

that is turned open 4.0 turns. Referring to Table 11.1 it can be

determined that for a BDP200 with a 1/3 HP motor and a -102

drive operating on 230V/60Hz/3Ph that if will have a power

code = 24.

5. Determine the control type:

From item #5 in the example, the gas type is Propane Gas and

controls are Two Stage. Given the supply voltage listed in #7, we

can refer to Tables 18.1 and 18.2 to determine what controls are

needed. This results in a Control Code (CC) = 88.

At this point we have a full model number of:

BDP200AE2488NBAN

6. Altitude:

Since deration of gas fired unit heaters is only required for

units to be installed at 2,000 ft or greater, no high altitude kit is

required.
