6-175.9 • APRIL, 2018

MODEL PTS / BTS

TABLE OF CONTENTS

Modine’s separated combustion unit heaters are designed for the heating requirements of commercial and industrial buildings with select models available for residential garage heating as well. The separated combustion units draw combustion air from outside to ensure that the unit will always have plenty of fresh, clean air for combustion, reducing common concerns about dusty, dirty, humid, or negative space pressure applications. In addition, by drawing the combustion air from the outside, the overall heating efficiency is increased.

With 13 propeller and 11 blower model sizes available, the units cover a wide variety of applications with input ranges from 30,000 to 400,000 Btu/Hr in either natural or propane gas. This catalog describes the design benefits, construction features, performance data, unit selection procedure, and the optional and accessory devices available.

j Power Exhauster (STD) All units are supplied with a round vent pipe and

combustion air inlet pipe connections.

k Pressure Switch (STD) An automatic reset vent pressure switch is supplied on

all units and is designed to prevent operation of the main burner in the event there is restricted venting of flue products. This restriction may occur due to an improper vent diameter, long vent runs, un-approved vent terminal, high winds, high negative pressure within space, etc. After the cause of the restriction has been corrected, the pressure switch will reset automatically.

l Integrated Direct Spark Control Board (STD) The integrated direct spark ignition control combines all

furnace control functions. The integrated board provides digital control of the air mover, inducer, ignition, gas valve and flame sense as well as monitoring the safety circuit at all times. The board includes LED diagnostics for trouble shooting and a fused power supply.

m Gas Valve - (See Table 12.2)

UNIT SELECTION

Selection Procedure

In order to properly select a unit heater it is necessary to have the following basic information.

1. Heating output capacity

Model size output is to be matched against the heat loss to

be replaced.

2. External static pressure (blower units only)

The external static pressure (E.S.P.) is determined using the ASHRAE Guide for duct losses or provided by the design engineer.

3. Accessory internal static pressure (transitions, filters,

etc.) (blower units only)

The critical accessories are those that add internal static

pressure (I.S.P.) to the unit. Once these items are determined, the total pressure drop can be determined (if applicable).

4. Heat exchanger material

The heat exchanger type is determined by the application.

The standard heat exchanger material is aluminized steel. A 409 stainless steel heat exchanger is recommended when the combined entering/return air to the unit is below 40°F or in high humidity applications.

5. Type of fuel

Either natural or propane gas determined by the design

engineer.

6. Gas controls

Either single stage or two stage, as determined by the

design engineer.

7. Main power supply voltage to unit

Selection Example (Propeller Unit)

Selection Example Conditions (Propeller Unit)

Select a unit heater to meet the following conditions:

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

2. External Static Pressure = 0.0

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

4. Heat exchanger and burner = 409 Stainless Steel

5. Gas Type = Natural

6. Gas Controls = Single Stage

7. Supply Voltage: 460V/60Hz/3Ph

With the information listed above, the basic model, using the information in this catalog and the Model Nomenclature shown on page 23, can be selected as shown:

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

Using the Heating output capacity, the Furnace Input Rating

is determined from Table 6.1. 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, propeller, separated combustion unit heater is PTS. The model and size are a PTS200.

2. Determination of Heat Exchanger Material:

From item #4 in the example, the Heat Exchanger required is

409 Stainless Steel. Thus, the Heat Exchanger Material = S from the Model Nomenclature on page 23.

3. Determine the Ignition Type:

The Ignition Type = S from the Model Nomenclature on page 23.

4. Determine Power Code Required:

Referring to Table 6.2, it can be seen that the supply

voltage from the example conditions is not available (460V). A transformer kit selected later in this example must be used. In this instance, from Table 6.2 select the 115V/60Hz/1Ph power code (PC) = 01 unit.

5. Determine the control type:

From items #5 and #6 in the example conditions, the gas type

is Natural Gas and controls are Single Stage. From Table

12.2, we are directed to use Control Code (CC) of 11.

6. Determine the fan guard type:

No specific type of fan guard was specified, so select Fan

Guard = S from the Model Nomenclature on page 23.

At this point we have a full model number of: PTS200SS0111SBAN

7. Determination of transformer:

To operate a 115V/60Hz/1Ph unit on 460V/60Hz/3Ph supply

power a unit step down transformer must be selected. By referring to Table 12.1 we see that a 460V to 115V step down transformer is required. As noted in the footnote for Table 12.1, the size can be determined to be 0.75kVA from Table 6.2.

6-175.9

UNIT SELECTION

Selection Example (Blower Unit)

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 at this point, but filters may be added later.

4. Heat exchanger and burner = Aluminized Steel

5. Gas Type = Propane

6. Gas Controls = Two Stage

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

8. CFM = 2,400

With the information listed above, the basic model, using the information in this catalog and the Model Nomenclature shown on page 23, can be selected as shown:

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

Using the Heating output capacity, the Furnace Input Rating

is determined from Table 7.1. 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, separated combustion unit heater is BTS. The model and size are a BTS200.

2. Determination of Heat Exchanger Material:

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

is aluminized steel. Thus, the Heat Exchanger Material = A from the Model Nomenclature on page 23.

3. Determine the Ignition Type:

The Ignition Type = S from the Model Nomenclature on page 23.

4. Determine Power Code Required:

From page 10 we see that a unit requiring a static of 0.2 and

a cfm of 2400 requires a 1/2 horsepower motor with a -233 drive that is turned open 1.5 turns. Referring to Table 9.1 it can be determined that for a BTS200 with a 1/2 HP motor and a -233 drive operating on 230V/60Hz/3Ph that it will have a power code = 08. However, note that if filters are added later, that drive/motor combination will not be sufficient. Two alternate drive selections could have been made with a 1hp motor with either a -253 or -229 drive. The power code would be 30 or 19 respectively. Note that the 229 drive would likely be the best choice, as the turns open is near the center of the range.

5. Determine the control type:

From items #5 and #6 in the example, the gas type is

Propane Gas and controls are Two Stage. From Table 12.2, we are directed to use Control Code (CC) = 22.

At this point we have a full model number of: BTS200AS1922NBAN

6. Determination of Transformer:

To operate the BTS200AS1922NBAN on 230V/60Hz/3ph

supply voltage, we need to review Table 12.1 to determine if any field installed transformers are required. The table indicates that we need a 230V to 115V step down transformer for the power exhaust and gas control circuit voltage. As indicated in the footnote for that table, Table 7.5 directs us to the correct size for this model, which is 0.5kVA. Transformers for blower models are typically smaller than those used for propeller models, as the transformer is not needed for the blower motor.
