atmospheres will cause accelerated corrosion resulting in a reduction of the normal life of the units.

IMPORTANT

To prevent premature heat exchanger failure, do not locate ANY gas-fired appliances in areas where corrosive vapors (i.e. chlorinated, halogenated or acidic) are present in the atmosphere.

Location Recommendations

1. When locating the heater, consider general space and heating requirements, availability of gas and electrical supply, and proximity to vent locations.

2. Avoid installing units in extremely drafty locations. Drafts can cause burner flames to impinge on heat exchangers which shortens life. Maintain separation between units so discharge from one unit will not be directed into the inlet of another.

3. Be sure the structural support at the unit location site is adequate to support the unit's weight. For proper operation

the unit must be installed in a level horizontal position.

4. Do not install units in locations where the flue products can be drawn into the adjacent building openings such as windows, fresh air intakes, etc.

5. Be sure that the minimum clearances to combustible

materials and recommended service clearances are maintained. Units are designed for installation on non- combustible surfaces with the minimum clearances shown in Figure 4.1 and Tables 4.1 and 4.2.

6. Units exposed to inlet air temperatures of 40°F or less, may experience condensation, therefore, provisions should be made for disposal of condensate.

7. When locating units, it is important to consider that the

exhaust vent piping must be connected to the outside atmosphere.

8. Maximum equivalent vent lengths are listed in "Section A -

General Instruction - All Units" of the Venting Instructions.

9. Do not install units in locations where gas ignition system is exposed to water spray, rain, or dripping water.

10. Do not install units below 7', measured from the bottom of the unit to the floor, unless properly guarded to provide protection from moving parts.

Combustion Air Requirements

The National Fuel Gas Code defines an “unconfined space” as a space whose volume is greater than 50 cubic feet per 1,000 Btu/Hr input of the installed appliance(s). A confined space is 50 cubic feet or less per 1,000 Btu/Hr input of the installed appliance(s).

Units installed in tightly sealed buildings or confined spaces must be provided with two permanent openings, one near the top of the confined space and one near the bottom. Each opening should have a free area of not less than one square inch per 1,000 BTU per hour of the total input rating off all units in the enclosure, freely communicating with interior areas having, in turn adequate infiltration from the outside.

For further details on supplying combustion air to a confined (tightly sealed) space or unconfined space, see the National Fuel Gas Code ANSI Z223.1 (NFPA 54) or CSA-B149.1 Installation Code - latest edition.

Sound and Vibration Levels

All standard mechanical equipment generates some sound and vibration that may require attenuation. Libraries, private offices and hospital facilities will require more attenuation, and in such cases, an acoustical consultant may be retained to assist in the application. Locating the equipment away from the critical area is desirable within ducting limitations. Generally, a unit should be located within 15' of a primary support beam. Smaller deflections typically result in reduced vibration and noise transmission.

6-580.10

INSTALLATION

UNIT MOUNTING

1. Be sure the means of suspension is adequate to support the weight of the unit (see pages 24 and 25 for unit weights).

2. For proper operation and to assure that flames are directed into the center of the heat exchanger tubes, the unit must be installed in a level horizontal position. Use a spirit level to ensure that the unit is suspended correctly.

3. Clearances to combustibles as specified in Figure 4.1 and Ta bles 4.1 and 4.2 must be strictly maintained.

4. All standard units are shipped fully boxed. Larger units are

also supplied with skid supports on the bottom of the box. The larger units may be lifted from the bottom by means of a fork lift or other lifting device only if the shipping support skids are left in place and the forks support the whole depth of the unit. If the unit must be lifted from the bottom for final installation without the carton in place, be sure to properly support the unit over its entire length and width to prevent damage. When lifting units, make sure the load is balanced.

5. Propeller models up to size 350 have 2 mounting holes, size

350 and above have 4 mounting holes and blower models up to size 350 have 4 mounting holes, size 350 and above have 6 mounting holes. Units with two point suspension incorporate a level hanging feature. Depending on what options and accessories are being used, the heater may not hang level as recieved from the factory. Do not hang heaters with deflector hoods until referring to the “Installation Manual for Deflector Hoods” and making the recommended preliminary adjustments on the heater, while the heater is resting on the floor. The units can be mounted with 3/8"-16 threaded rod as follows:

• On each piece of threaded rod used, screw a nut a

distance of about 1" onto the end of the threaded rods that will be screwed into the unit heater.

• Place a washer over the end of the threaded rod and

screw the threaded rod into the unit heater weld nuts on the top of the heater at least 5 turns, and no more than 10 turns. Tighten the nut first installed onto the threaded rod to prevent the rod from turning.

• Drill holes into a steel channel or angle iron at the same

center-line dimensions as the heater that is being installed. The steel channels or angle iron pieces need to span and be fastened to appropriate structural members.

• Cut the threaded rods to the preferred length, place them

through the holes in the steel channel or angle iron and secure with washers and lock nuts or lock washers and nuts. A double nut arrangement can be used here instead of at the unit heater (a double nut can be used both places but is not necessary).

• Do not install standard unit heaters above the maximum

mounting height shown in Table 19.1.

NOTE: A pipe hanger adapter kit, shown in Figure 5.2 is

available as an accessory. One kit consists of two drilled 3/4" IPS pipe caps and two 3/8" - 16 x 1-3/4" capscrews to facilitate threaded pipe suspension. Two kits would be required for PDP unit sizes 350 and 400 and all BDP units except size 350 and 400, and 3 kits for BDP unit sizes 350 and 400.

2. A built-in power exhauster is provided - additional external power exhausters are not required or permitted.

3. If an existing heater is being replaced, it may be necessary to resize the venting systems. Improperly sized venting systems can result in vent gas leakage or the formation of condensate. Refer to the National Fuel Gas Code ANSI Z223.1 (NFPA 54) or CSA B149.1 - latest edition. Failure to follow these instructions can result in serious injury or death.

4. Under no circumstances should two sections of double wall vent pipe be joined together within one horizontal vent system due to the inability to verify complete seal of inner pipes.

CAUTION

Installation must conform with local building codes or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1 (NFPA 54) - latest edition. In Canada installation must be in accordance with CSA B149.1.

Model PDP and BDP unit heaters must be vented with the proper passageway as described in these instructions to convey flue gases from the unit or the vent connector to the outside atmosphere.

The venting instructions are organized in sections, based on installation type. The sections are identified as follows:

Instructions

A General Instructions for ALL Installations

B VERTICAL CATEGORY I vent systems ➀

C HORIZONTAL CATEGORY III vent systems ➀

 The differences between vertical and horizontal vent systems will be identified in

"Section A - General Instructions - All Units".

Applicable Installation Instructions

by Vent System Type

in Table 6.1, making the vent system as straight as possible. The equivalent length of a 5" elbow is 6' and for a 6" elbow is 7'.

A5. A minimum of 12" straight pipe is recommended from the

flue outlet before turns in the vent pipe.

A6. Horizontal sections of vent pipe are to be installed with a

minimum downward slope from the appliance of 1/4" per foot and suspended securely from overhead structures at points not greater than 3' apart.

A7. Fasten individual lengths of vent together with at least

3 corrosion resistant sheet metal screws.

A8. Keep single wall vent pipe at least 6" from combustible

materials. For double wall vent pipe, follow the vent pipe

manufacturer’s clearances to combustibles. The minimum

distance from combustible materials is based on the combustible material surface not exceeding 160°F. Clearance from the vent pipe (or the top of the unit) may be required to be greater than 6" if heat damage other than fire could result (such as material distortion or discoloration).

A9. Avoid venting through unheated space when possible.

When venting does pass through an unheated space or if the unit is installed in an environment that promotes condensation, insulate runs greater than 5' to minimize condensation. Inspect for leakage prior to insulating and use insulation that is noncombustible with a rating of not less than 400°F. Install a tee fitting at the low point of the vent system and provide a drip leg with a clean out cap as shown in Figure 8.1.

A10. When the vent passes through a combustible INTERIOR

wall or floor, a metal thimble 4" greater than the vent diameter is necessary. If there is 6' or more of vent pipe in the open space between the appliance and where the vent pipe passes through the wall or floor, the thimble need only be 2" greater than the diameter of the vent pipe. If a thimble is not used, all combustible material must be cut away to provide 6" of clearance. Where authorities have jurisdiction, Type B vent may be used for the last section of vent pipe to maintain clearance to combustibles while passing through wall or floor. See Figure 6.1. Any material used to close the opening must be noncombustible.

A11. All seams and joints of the single wall pipe must be sealed

with metallic tape or silastic suitable for temperatures up to 400°F. Wrap the tape 2 full turns around the vent pipe. One continuous section of double wall vent pipe may be used within the vent system to pass through the wall to the listed vent cap. Refer to instruction A12 in “Section A – General Instructions – All Units” for attaching double wall pipe to single wall pipe.

A12. The following are general instructions for double wall

(Type B) terminal pipe installation:

How to attach a single wall vent terminal to

double wall (Type B) vent pipe:

1. Look for the “flow” arrow on the vent pipe.

2. Slide the vent terminal inside the exhaust end of the double wall vent pipe.

3. Drill 3 holes through the pipe and the vent terminal. Using 3/4" long sheet metal screws, attach the cap to the pipe. Do not over tighten.

How to connect a single wall vent system to a double wall (Type B) vent pipe:

1. Slide the single wall pipe inside the inner wall of the double wall pipe.

2. Drill 3 holes through both walls of the single and double wall vent pipes. Using 3/4" sheet metal screws, attach the 2 pieces of pipe. Do not over tighten.

3. The gap between the single and double wall pipe must be sealed but it is not necessary to fill the full volume of the annular area. To seal, run a large bead of 400°F silastic around the gap.

(an example is shown in Figure 8.1), proceed to “Section B

- Vertical Vent System Installation”. For all other cases, proceed to the next section for Horizontal Category III Vent System Determination:

Horizontal Category III Vent

• Horizontal vent systems terminate horizontally (sideways)

(an example is shown in Figure 9.2).

• A vent system that terminates vertically but has a

horizontal run that exceeds 75% of the vertical rise is considered horizontal.

• Horizontal vent configurations are Category III. Additional

requirements are covered in “Section C - Horizontal Category III Vent System Installation”.

INSTALLATION - VENTING

Section B – Vertical Vent System Installation

B1. This section applies to vertically vented Category I

vent systems and is in addition to “Section A – General Instructions – All Units”.

B2. Vertical vent systems terminate vertically and must be sized

in accordance with the National Fuel Gas Code, ANSI Z223.1 (NFPA 54) - latest edition.

B3. The horizontal portion of the vent run cannot exceed 75%

of the vertical rise (Example: If the vent height is 10', the horizontal portion of the vent system cannot exceed 7.5').

B4. It is recommended to install a tee with drip leg and clean out

cap as shown in Figure 8.1.

B5. The vent terminates a minimum of 5' above the vent

connector on the unit.

B6. All vertically vented heaters that are Category I must be

connected to a vent complying with a recognized standard, with a material acceptable to the authority having jurisdiction. Venting into a masonry chimney is not permitted. Refer to the National Fuel Gas Code, ANSI Z223.1 (NFPA 54) - latest edition for instructions on common venting.

B7. Use a listed vent terminal to reduce down drafts and

moisture in the vent.

B8. Double wall vent pipe is recommended, although single wall

can be used if the requirements of the National Fuel Gas Code are followed.

B9. Vertical vents must terminate a minimum horizontal and

vertical distance from roof lines and adjacent walls or obstructions. These minimum distances are outlined as follows (based on National Fuel Gas Code requirements for vents with diameters less than 12"):

• For double wall vent pipe and 8' or greater horizontal

distance to any vertical wall or similar obstruction, the vent must terminate above the roof in accordance with Figure 8.1 and Table 8.1.

• For double wall vent pipe and less than 8' horizontal

distance to any vertical wall or similar obstruction, the vent must terminate at least 2' above the highest point where it passes through a roof of a building and at least 2' higher than any portion of a building within a horizontal distance of 10' (see Figure 8.1).

INSTALLATION - VENTING

Section C – Horizontal, Category III Vent System Installation

C1. This section applies to horizontally vented Category III

vent systems and is in addition to “Section A – General

Instructions – All Units”. C2. Horizontal vent systems terminate horizontally (sideways). C3. All seams and joints must be sealed with metallic tape or

silastic suitable for temperatures up to 400°F. Wrap the

tape 2 full turns around the vent pipe. For single wall vent

systems, 1 continuous section of double wall vent pipe may

be used within the vent system to pass through the wall

to the listed vent cap. Under no circumstances should 2

sections of double wall vent pipe be joined together within

1 vent system due to the inability to verify complete seal of

inner pipes. Refer to instruction A10 in “Section A – General

Instructions – All Units” for attaching double wall pipe to

single wall pipe. C4. Refer to Table 9.1 for total minimum and maximum vent

lengths, making the system as straight as possible. The

equivalent length of a 90° elbow is 6' for 5" diameter and

7' for 6" diameter. C5. All horizontal Category III vents must be terminated with a

listed vent cap. The cap must terminate a minimum distance

beyond the exterior wall surface as shown in Figure 9.2 and

Table 9.1. The vent must be supported as shown in Figure

9.1. Precautions must be taken to prevent degradation of

building materials by flue products.

Figure 9.2 - Horizontal Venting

C9. For a vent termination located under an eave, the distance

of the overhang must not exceed 24". The clearance to combustibles above the exterior vent must be maintained at a minimum of 12". Consult the National Fuel Gas Code for additional requirements for eaves that have ventilation openings.

C10. Once venting is complete, proceed to the section titled

“Installation – Gas Connections”.

C6. When condensation may be a problem, the vent system shall

not terminate over public walkways or over an area where

condensate or vapor could create a nuisance or hazard or

could be detrimental to the operation of regulators, relief

openings, or other equipment. C7. The venting system must be exclusive to a single unit, and

no other unit is allowed to be vented into it. C8. When vented horizontally, maintain a 1/4" per foot rise away

from the heater and place a drip leg with clean out near the

unit as shown in Figure 9.2. Where local authorities have

jurisdiction, a 1/4” per foot downward slope is acceptable

with a drip leg and clean out near the exit of the vent as

shown in Figure 9.2, or allow the condensate to drip out

INSTALLATION

GAS CONNECTIONS

WARNING

1. All field gas piping must be pressure/leak tested prior to operation. Never use an open flame. Use a soap solution or equivalent for testing.

2. Gas pressure to appliance controls must never exceed 14" W.C. (1/2 psi).

3. To reduce the opportunity for condensation, the minimum

sea level input to the appliance, as indicated on the serial plate, must not be less than 5% below the rated input, or 5% below the minimum rated input of dual rated units.

CAUTION

1. Purging of air from gas lines should be performed as described in the National Fuel Gas Code, ANSI Z223.1 (NFPA 54) - latest edition or in Canada CSA-B149 codes.

2. When leak testing the gas supply piping system, the appliance and its combination gas control must be isolated during any pressure testing in excess of 14" W.C. (1/2 psi).

3. The unit should be isolated from the gas supply piping system by closing its field installed manual shut-off valve. This manual shut-off valve should be located within 6' of the heater.

4. Turn off all gas before installing appliance.

IMPORTANT

To prevent premature heat exchanger failure, the input to the appliance, as indicated on the serial plate, must not exceed the rated input by more than 5%.

1. Installation of piping must conform with local building codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1 (NFPA 54) - Latest Edition. In Canada, installation must be in accordance with CSA-B149.1.

2. Piping to units should conform with local and national requirements for type and volume of gas handled, and pressure drop allowed in the line. Refer to Table 10.1 to determine the cubic feet per hour (cfh) for the type of gas and size of unit to be installed. Using this cfh value and the length of pipe necessary, determine the pipe diameter from Table 10.2. Where several units are served by the same main, the total capacity, cfh and length of main must be considered. Avoid pipe sizes smaller than 1/2". Table

10.1 allows for a 0.3" W.C. pressure drop in the supply pressure from the building main to the unit. The inlet pressure to the unit must be 6-7" W.C. for natural gas and 11-14" W.C. for propane gas. When sizing the inlet gas pipe diameter, make sure that the unit supply pressure can be met after the 0.3" W.C. has been subtracted. If the

0.3" W.C. pressure drop is too high, refer to the Gas

Engineer’s Handbook for other gas pipe capacities.

3. Install a ground joint union with brass seat and a manual

shut-off valve adjacent to the unit for emergency shut-off and easy servicing of controls, including a 1/8" NPT plugged tapping accessible for test gauge connection (see Figure 10.1).

4. Use 2 wrenches when connecting field piping to units.

5. Provide a sediment trap before each unit and in the line

where low spots cannot be avoided (see Figure 10.1).

6. When pressure/leak testing, pressures above 14" W.C. (1/2 psi), close the field installed shut-off valve, disconnect the appliance and its combination gas control from the gas supply line, and plug the supply line before testing. When testing pressures 14" W.C. (1/2 psi) or below, close the manual shut-off valve on the appliance before testing.

INSTALLATION - HIGH ALTITUDE ACCESSORY KIT

HIGH ALTITUDE ACCESSORY KIT

Modine’s gas-fired equipment standard input ratings are

certified by ETL. For elevations above 2,000', ANSI Z223.1 requires ratings be reduced 4 percent for each 1000' above sea level. For units in Canada, CSA requires that ratings be reduced 10 percent at elevations above 2,000'. The high altitude adjustment instructions and pressure switch kits listed in this manual are for use with units that will be installed over 2,000' These methods and kits comply with both ANSI Z223.1 and CSA requirements.

If a unit is to be installed at higher elevations AND converted from natural gas to propane gas operation, a propane conversion kit must be used in conjunction with the pressure adjustment methods and pressure switch kits listed herein. For the Selection and Installation Instructions for propane conversion kits, please see the latest revision of Modine Manual 75-511.

Selection of the Proper Pressure and Kit

To determine the proper manifold pressure at altitude and if required, the proper combustion air pressure switch kit, the full model number of the heater, the fuel to be used, and the altitude the unit will be installed at must be known. Refer to the unit serial plate or carton label to obtain the necessary information about the unit.

After obtaining this information, refer to the gas pressure and selection charts shown in Tables 11.1 through 11.3. The pressure charts are differentiated by elevation, fuel type, and country the product is being installed in. The selection charts are differentiated by product type, altitude and fuel type. If

converting from natural gas to propane gas and operation at high altitude, both a propane conversion kit and a pressure switch kit must be used (if applicable). Selection

charts include the proper kit suffix, when required.

Manifold Pressure Adjustment

The inlet pressure to the unit must be confirmed to be within acceptable limits (6-7" W.C. for natural gas and 11-14" W.C. for propane gas) before opening the shutoff valve or the combination gas valve may be damaged.

Heaters for use with natural gas have gas valves factory set at

3.5” W.C. manifold pressure at 7.0" W.C. inlet pressure. Units for use with propane gas are set for 10.0" W.C. manifold

pressure at 14.0” W.C. inlet pressure. Installation above 2,000'. elevation requires adjustment of the

manifold pressure as described.

Derated BTU Content Gas and Manifold Pressure Calculation

Some utility companies may derate the BTU content (heating value) of the gas provided at altitude to a value other than 1,050

BTU/ft

for natural gas or 2,500 BTU/ft3 for propane gas to allow certain heating appliances to be used with no manifold pressure adjustments. For this reason it is necessary that the supplying utility be contacted for detailed information about the gas type and BTU content (heating value) before operating any heater. Tables 11.1 and 11.2 show the standard derated heating values

(4% per 1,000' of elevation in the USA and 10% between 2,001’

and 4,500' elevation in Canada) of natural and propane gases at various altitudes. If the utility is supplying gas with heating values as shown in Tables 11.1 and 11.2, the manifold pressure should be set to 3.5" W.C for natural gas and 10.0" W.C. for propane gas.

NOTE: Only the high fire gas pressure need be adjusted, low fire gas pressure should remain the same.

Table 11.1 - Natural Gas Heating Values at Altitude

➀ Values shown are for 3.5" W.C. manifold pressure, for other BTU content values (available from local utility) use Equation 12.1 to calculate manifold pressure. ➁ Values shown are for 10.0" W.C. manifold pressure, for other BTU content values (available from local utility) use Equation 12.1 to calculate manifold pressure. ➂ When installed at altitudes above 2,000', a pressure switch may need to be changed. Refer to Table 11.3 to determine if a switch change is required. ➃ Gas heating values are derated 4% per 1,000' of elevation in the USA and 10% between 2,000' and 4,500' elevation in Canada in accordance with ANSI Z223.1

and CSA-B149, respectively.

WARNING

1. Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage.

2. All appliances must be wired strictly in accordance with

wiring diagram furnished with the appliance. Any wiring different from the wiring diagram could result in a hazard to persons and property.

3. Any original factory wiring that requires replacement must be

replaced with wiring material having a temperature rating of at least 105°C.

4. Ensure that the supply voltage to the appliance, as indicated

on the serial plate, is not 5% greater than rated voltage.

CAUTION

Ensure that the supply voltage to the appliance, as indicated on the serial plate, is not 5% less than the rated voltage.

1. Installation of wiring must conform with local building codes, or in the absence of local codes, with the National Electric Code ANSI/NFPA 70 - Latest Edition. Unit must be electri cally grounded in conformance to this code. In Canada, wiring must comply with CSA C22.1, Part 1, Electrical Code.

2. Two copies of the unit wiring diagram are provided with each unit. One is located in the electrical junction box and the other is suppled in the literature packet. Refer to this diagram for all wiring connections.

3. Make sure all multi-voltage components (motors, transform ers, etc.) are wired in accordance with the power supply voltage.

4. The power supply to the unit must be protected with a fused or circuit breaker switch.

5. The power supply must be within 10 percent of the voltage rating and each phase must be balanced within 2 percent of each other. If not, advise the utility company.

6. External electrical service connections that must be installed include:

a. Supply power connection (120, 208, 240, 480, or 575 volts). b. Thermostats, summer/winter switches, or other accessory

control devices that may be supplied (24 volts).

NOTE: Certain units will require the use of a field step-down transformer. Refer to the serial plate to determine the unit supply voltage required. Additional information may be found in Tables 19.2 and 19.3 and in the step down transformer installation instructions.

7. Refer to Figure 18.1 for the electrical junction box locations.

8. All supply power electrical connections are made in the electrical junction box of the unit. The low voltage (thermostat and accessory control devices) can be wired to the terminals on the electrical junction box. Refer to the wiring diagram for the terminal location of all low voltage wiring.

DUCT INSTALLATION

Do not attempt to attach ductwork of any kind to propeller models.

When installing the heater, always follow good duct design practices for even distribution of the air across the heat exchanger. Recommended layouts are shown in Figure 13.1. When installing blower units with ductwork the following must be done.

1. Provide uniform air distribution over the heat exchanger.

Use turning vanes where required (see Figure 13.1).

2. Provide removable access panels in the ductwork on the downstream side of the unit heater. These openings should be large enough to view smoke or reflect light inside the casing to indicate leaks in the heat exchanger and to check for hot spots on exchanger due to poor air distribution or lack of sufficient air.

3. If ductwork is connected to the rear of the unit use a Modine blower enclosure kit or if using a field designed enclosure maintain dimensions of the blower enclosure as shown on page 25.

Additional Requirements for Blower Model BDP

Determining Blower Speed

The drive assembly and motor on all blower units are factory assembled and adjusted for operation under average conditions of air flow and without any external static pressure. The motor sheave should be adjusted as required when the unit is to be operated at other than average air flows and/or with external static pressures. Adjustment must always be within the performance range shown on page 20 and the temperature rise

range shown on the unit’s rating plate.

To determine the proper blower speed and motor sheave turns open, the operating conditions must be known. For example, a model BDP350 unit, operating with no external static pressure, (e.g. no ductwork, nozzles, etc.) is to deliver an air volume of 6481 cfm (cfm = cubic feet per minute). This requires the unit be supplied with a 5 hp motor, a -207 drive, and the drive sheave set at 2.5 turns open to achieve a blower speed of 960

rpm (see performance table for units with or without blower enclosure, page 20). See “Blower Adjustments” for setting of drive pulley turns open.

If a blower unit is to be used with ductwork or nozzles, etc., the total external static pressure under which the unit is to operate, and the required air flow must be known before the unit can be properly adjusted. Any device added externally to the unit, and which the air must pass through, causes a resistance to air flow called pressure loss.

If Modine filters are used, the pressure loss through the filters is included in the performance data on page 20. If Modine supplied discharge nozzles are used, the pressure drop of the nozzles can be found footnoted at the bottom of page

23. If filters, nozzles or ductwork are to be used with the unit, and they are not supplied by Modine, the design engineer or installing contractor must determine the pressure loss for the externally added devices or ductwork to arrive at the total external static pressure under which the unit is to operate.

Once the total static pressure and the required air flow are known, the operating speed of the blower can be determined and the correct motor sheave adjustments made. As an example, a model BDP350 is to be used with a Modine supplied blower enclosure and filters attached to ductwork by others. The unit is to move 6481 cfm of air flow against an external static pressure of 0.2" W.C, which must be added for the filter pressure drop for a total of 0.4" W.C. total pressure drop. The performance table on page 20 for a BDP350, at 6481 cfm and

0.4" W.C. static pressure, shows that the unit will require a 5 hp motor using a -207 drive, and the motor sheave should be set at .5 turns open to achieve a blower speed of 1050 rpm.

To Install

1. Remove and discard the motor tie down strap and the shipping block beneath the belt tension adjusting screw (Not used on all models.)

2. For 3 and 5 HP motors, affix sheave to the motor shaft and install motor on the motor mounting bracket. Install belt on blower and motor sheaves.

Figure 14.1 - Blower Model

THREADED MOUNTING BRACKETS ON

BLOWER ASSEMBLY

MOTOR MOUNTING

BRACKET

3. Adjust motor adjusting screw for a belt deflection of approximately 3/4" with five pounds of force applied midway between the sheaves (see Figure 14.3). Since the belt tension will decrease dramatically after an initial run-in period, it is necessary to periodically re-check the tension. Excessive tension will cause bearing wear and noise.

4. The blower bearings are lubricated for life; however, before initial unit operation the blower shaft should be lubricated at the bearings with SAE 20 oil. This will reduce initial friction and start the plastic lubricant flowing.

5. Make electrical connections as outlined in the section “Electrical Connections” on page 13.

Blower Adjustments

Following electrical connections, check blower rotation to assure blow-through heating. If necessary interchange wiring to reverse blower rotation. Start fan motor and check blower sheave RPM with a hand-held or strobe-type tachometer. RPM should check out with the speeds listed in “Performance Data” shown on page 20. A single-speed motor with an adjustable motor sheave is supplied with these units. If blower fan speed changes are required, adjust motor sheave as follows:

NOTE: Do not fire unit until blower adjustment has been made or unit may cycle on limit (overheat) control.

1. Shut-off power before making blower speed

adjustments. Refer to “Determining Blower Speed” on page

13 and to “Performance Data” on page 20 to determine proper blower RPM.

2. Loosen belt and remove from motor sheave.

3. Loosen set screw on outer side of adjustable motor sheave

(see Figure 14.2).

4. To reduce the speed of the blower, turn outer side of motor

sheave counterclockwise.

5. To increase the speed of the blower, turn outer side of motor

sheave clockwise.

6. Retighten motor sheave set screw, replace belt and retighten

motor base. Adjust motor adjusting screw such that there is 3/4" belt deflection when pressed with 5 pounds of force midway between the blower and motor sheaves (see Figure

14.3). Since the belt tension will decrease dramatically after an initial run-in period, it is necessary to periodically re-check the tension to assure proper belt adjustment.

7. Check to make certain motor sheave and blower sheave are

aligned. Re-align if necessary.

8. Re-check blower speed after adjustment.

9. Check motor amps. Do not exceed amps shown on motor

nameplate. Slow blower if necessary.

10. Check air temperature rise across unit. Check temperature

rise against values shown in Performance Tables on page 20 to assure actual desired air flow is being achieved.

11. If adjustments are required, recheck motor amps after final

blower speed adjustment.

START-UP PROCEDURE

IMPORTANT

1. To prevent premature heat exchanger failure, observe heat exchanger tubes. If the bottom of the tubes become red while blower and furnace are in operation, check to be sure the blower has been set to the proper rpm for the application. Refer to page 14 for blower adjustments.

2. Start-up and adjustment procedures must be performed by a qualified service agency.

1. Turn off power to the unit at the disconnect switch. Check that fuses or circuit breakers are in place and sized correctly. Turn all hand gas valves to the “OFF” position.

2. Remove electrical junction box cover.

3. Check that the supply voltage matches the unit supply voltage listed on the Model Identification Plate. Verify that all wiring is secure and properly protected. Trace circuits to insure that the unit has been wired according to the wiring diagram. If installed at altitudes above 2,000' and the high altitude kit includes a combustion air proving switch, replace the switch in the unit with the switch provided in the kit. Take care to ensure that the tubing and electrical connections are securely fastened.

4. Check to insure that the venting system is installed correctly and free from obstructions.

5. Check to see that there are no obstructions to the intake and discharge of the unit.

6. For blower units, check the belt tension and sheave alignment. Refer to “Blower Adjustments” for proper belt tension.

7. Check bearings for proper lubrication (if applicable).

8. Check to make sure that all filters are in place and that they are installed properly according to direction of air flow (if applicable).

9. Perform a visual inspection of the unit to make sure no damage has occurred during installation. Lower bottom pan and visually inspect all components in the burner compartment. Check to ensure all fasteners are in place and the burner openings are properly aligned with the heat exchanger tubes and that the gas orifices are centered in the burner inspirator tube opening opening, as shown in Figure 16.2.

10. Check that all horizontal deflector blades are open a minimum of 30° as measured from vertical.

11. Turn on power to the unit at the disconnect switch. Check to insure that the voltage between electrical junction box terminals T1 and G is 24V.

12. Check the thermostat, ignition control, gas valve, and supply fan blower motor for electrical operation. If these do not function, recheck the wiring diagram. Check to insure that none of the Control Options have tripped.

1 3. Check the blower wheel for proper direction of rotation

when compared to the air flow direction arrow on the blower housing (if applicable). Blower wheel rotation, not air movement, must be checked as some air will be delivered through the unit with the blower wheel running backwards.

14. For blower units, check the blower speed (rpm). Refer to “Blower Adjustments” for modification.

15. Check the motor speed (rpm).

16. Check the motor voltage. On three phase systems, check to make sure all legs are in balance.

17. Check the motor amp draw to make sure it does not exceed the motor nameplate rating. On three phase systems, check all legs to insure system is balanced.

18. Recheck the gas supply pressure at the field installed manual shut-off valve. The minimum inlet pressure should be 6" W.C. on natural gas and 11" W.C. on propane gas. The maximum inlet pressure for either gas is 14" W.C. If inlet pressure exceeds 14" W.C., a gas pressure regulator must be added upstream of the combination gas valve.

6-580.10

19. Open the field installed manual gas shut-off valve.

20. Open the manual main gas valve on the combination gas valve. Call for heat with the thermostat and allow the pilot to light for intermittent pilot ignition. If the pilot does not light, purge the pilot line. If air purging is required, disconnect the pilot line at outlet of pilot valve. In no case should line be purged into heat exchanger. Check the pilot flame length (See “Pilot Flame Adjustment”).

21. Once the pilot has been established, check to make sure that the main gas valve opens. Check the manifold gas pressure (see “Main Gas Adjustment”) and flame length (see “Air Shutter Adjustment”) while the supply fan blower is operating. Inspect the condition of the main flame and if necessary, resolve flame appearance problems (see “Burner Flame Adjustment” and Figures 28.1 through 28.4).

22. Check to insure that gas controls sequence properly (see

“Control Operating Sequence”). Verify if the unit has any additional control devices and set according to the instructions in the “Control Options”.

23. Once proper operation of the unit has been verified,

remove any jumper wires that were required for testing.

24. Replace the electrical junction box cover.

25. If installed at altitudes above 2,000', affix label included with high altitude kit and fill in all fields with a permanent marker.

Pilot Burner Adjustment

The pilot burner is orificed to burn properly with an inlet pressure of 6-7" W.C. on natural gas and 11-14" W.C. on propane gas, but final adjustment must be made after installation. If the pilot flame is too long or large, it is possible that it may cause soot and/or impinge on the heat exchanger, causing failure. If the pilot flame is shorter than shown, it may cause poor ignition and result in the controls not opening the combination gas control. A short flame can be caused by a dirty pilot orifice. Pilot flame condition should be observed periodically to assure trouble-free operation.

To Adjust the Pilot Flame

1. Create a call for heat from the thermostat.

2. Remove the cap from the pilot adjustment screw. For

location, see the combination gas control literature supplied with unit.

3. Adjust the pilot length by turning the screw in or out to

achieve a soft steady flame 3/4" to 1" long and encompassing 3/8"-1/2" of the tip of the thermocouple or flame sensing rod (see Figure 15.1).

4. Replace the cap from the pilot adjustment screw.

Figure 15.1 - Correct Pilot Flame

3/4" to 1"

START-UP PROCEDURE

Main Burner Adjustment

The gas pressure regulator (integral to the combination gas control) is adjusted at the factory for average gas conditions. It is important that gas be supplied to the unit heater in accordance with the input rating on the serial plate. Actual input should be checked and necessary adjustments made after the unit heater is installed. Over-firing, a result of too high an input, reduces the life of the appliance and increases maintenance. Under no circumstances should the input exceed that shown on the serial plate.

Measuring the manifold pressure is done at the outlet pressure tap of the gas valve (see Figure 16.1).

To Adjust the Manifold Pressure

1. Move the field installed manual shut-off valve to the “OFF” position.

2. Remove the 1/8" pipe plug in the pipe tee or gas valve and attach a water manometer of “U” tube type which is at least 12" high.

3. Move the field installed manual gas shut-off valve to the “ON” position.

4. Create a high fire call for heat from the thermostat.

5. Determine the correct high fire manifold pressure (3.5" W.C. for natural gas, 10" W.C. for propane gas). (Pressures at 0-2,000' elevation are 3.5" W.C. for natural gas, 10" W.C. for propane gas, for elevations above 2,000' refer to the instructions in “Gas Connections - High Altitude Accessory Kit” on page 11). Adjust the main gas pressure regulator spring to achieve the proper manifold pressure (for location, see the combination gas control literature supplied with unit).

6. After adjustment, move the field installed manual shut-off valve to the “OFF” position and replace the 1/8" pipe plug.

7. After the plug is in place, move the field installed manual shut-off valve to the “ON” position and recheck pipe plugs for gas leaks with soap solution.

It may also be necessary to adjust the manifold position in addition to adjusting air shutters to obtain proper flame. Follow the instructions under “Natural Gas Flame Control” for adjusting the manifold.

Burner Flame Adjustment

Proper operation provides a soft blue flame with a well-defined inner core. A lack of primary air will reveal soft yellow-tipped flames. Excess primary air produces short, well-defined flames with a tendency to lift off the burner ports. For both natural and propane gas, the flame may be adjusted by sliding the manifold. Also, for propane gas, the air shutters can be adjusted to control the burner flame height. The air shutters can be accessed by lowering the bottom pan of the unit heater.

Natural Gas Flame Control

Control of burner flames on unit heaters utilizing natural gas is achieved by resetting the manifold position to either increase or decrease primary combustion air. Prior to flame adjustment, operate unit heater for about fifteen minutes. The main burner flame can be viewed after loosening and pushing aside the gas designation disc on the back of the unit.

To increase primary air, loosen the manifold mounting screws and move the manifold away from the burner until the yellowtipped flames disappear (see Figure 16.2). To decrease primary air, move manifold closer to the burner until flames no longer lift from burner ports, but being careful not to cause yellow tipping. Retighten manifold mounting screws after adjustment.

Propane Gas Flame Control

An optimum flame will show a slight yellow tip. Prior to flame adjustment, operate heater for at least 15 minutes. Loosen air shutter set screws and move the air shutters away from the manifold to reduce the primary air until the yellow flame tips appear (see Figure 16.3). Then increase the primary air until yellow tips diminish and a clean blue flame with a well-defined inner cone appears.

START-UP PROCEDURE

Control Operating Sequence

All units are supplied with intermittent pilot systems with continuous retry control as standard. For intermittent pilot systems, both the main burner and pilot are turned off 100% when the thermostat is satisfied. For all units, the system will attempt to light the pilot for 70 seconds. If the pilot is not sensed, the ignition control will wait approximately 6 minutes with the combination gas control closed and no spark. After 6 minutes, the cycle will begin again. After 3 cycles, some ignition controllers lockout for approximately 1 hour before the cycle begins again. This will continue indefinitely until the pilot flame is sensed or power is interrupted to the system. Refer to Table 18.1 for control code descriptions. Specific descriptions of the control sequence for different control codes are listed below.

1. The thermostat calls for heat.

2. The power exhauster relay is energized, starting the power exhauster motor. Once the motor has reached full speed, the differential pressure switch closes.

3. The pilot valve opens and the ignitor sparks for 70 seconds in an attempt to light the pilot.

4. Once the pilot is lit, the flame sensor proves the pilot and

stops the ignitor from sparking.

5. On single stage units, the main gas valve is opened and the

main burner is lit to 100% full fire. On two stage units, the gas valve may open at either 50% or 100%, depending on what the two stage thermostat is calling for.

6. The air mover starts after 30 to 90 seconds to allow the heat exchanger to warm up.

7. The unit continues to operate until the thermostat is satisfied, at which time both the main and pilot valves close 100%.

8. The air mover stops after 30 to 90 seconds to remove residual heat from the heat exchanger.

➀

➃

All units include the standard (STD) features. The unit must be reviewed to determine the optional (OPT) features that may have been supplied with the unit.

➀ Gas Valve

a) Single Stage Gas Valve - (STD) The main gas valve provides the pilot, regulator, main gas, and manual shutoff functions. For additional information, see the supplier literature included with the unit.

b) Two Stage Gas Valve - (OPT)

The two stage gas valve provides the pilot, regulator, main gas (100% and 50% fire), and manual shutoff functions. For additional information, see the supplier literature included with the unit.

➁ Ignition controller - (STD)

The ignition controller is factory installed on the back of the unit heater with the spark igniter and sensor located on the burner. For additional information, refer to “Control Operating Sequence” on page 16 and the supplier literature included with the unit.

➂ Time Delay Relay - (STD)

The time delay relay is factory installed in electrical junction box and controls propeller/blower motor function. For singlephase units below 2 Hp, the time delay relay controls the motor directly. For single-phase units 2 Hp and greater and all three phase units, the time delay relay controls the motor starter. For additional information, refer to “Control Operating Sequence” on page 17.

➃ Low Voltage Terminal Board - (STD)

The low voltage terminal board is located in the electrical junction box. The terminal board is labeled to match the electrical wiring diagram provided with the unit. All low voltage field wiring connections should be made to the exposed side of the terminal board (exterior of electrical junction box) to prevent miswiring by modifying the factory wiring, which is inside the electrical junction box.

➄ Control Step Down Transformer - (STD)

The control step down transformer is located in the electrical junction box. The transformer is used to step down the supply power (115V, 208V, 230V, 460V, 575V) to 24V. This transformer is used to control the gas controls, fan delay relay, field supplied motor starter, etc. All unit heaters are supplied with a 40VA control step down transformer. To determine the control transformer supplied as well as any accessory/field supplied transformers required, reference the supply voltage listed on the serial plate and reference Tables 19.2 and 19.3.

⑥

➈

➅ High Limit Switch - (STD)

The automatic reset high limit switch is factory installed on the left side (air blowing at you) of the unit heater. If the limit temperature is exceeded, the gas controls are de-energized until the switch is cooled.

➆ Pressure Switch (STD)

An automatic reset vent pressure switch is designed to prevent operation of the main burner if there is restricted venting of flue products. This restriction may occur due to an improper vent diameter, long vent runs, unapproved 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. See the troubleshooting section for more information.

➇ Power Exhauster (STD)

All power vented unit heaters are supplied with a round vent pipe connection. Some models may require the use of a vent transition from the power exhauster outlet to the vent pipe (see Table 6.1). The power exhauster may be rotated 180° to allow for various venting directions.

➈ Blower Motor - (STD on BDP models only)

The blower motor can be provided in a variety of supply voltages and motor horsepowers. Refer to the model nomenclature to determine the motor provided. The blower motor is supplied with an adjustable sheave that can be used to increase/decrease the blower RPM. For instructions on changing the blower RPM, refer to “Blower Adjustments.”

MAINTENANCE

WARNING

When servicing or repairing this equipment, use only factoryapproved service replacement parts. A complete replacement parts list may be obtained by contacting the factory. Refer to the rating plate on the appliance for complete appliance model number, serial number, and company address. Any substitution of parts or controls not approved by the factory will be at the

owner’s risk.

CAUTION

1. Service or repair of this equipment must be performed by a qualified service agency.

2. Do not attempt to reuse any mechanical or electrical controllers which have been wet. Replace defective controller.

NOTE: To check most of the possible remedies in the troubleshooting guide listed in Table 27.1, refer to the applicable sections of the manual.

General Maintenance

The unit and venting system must be checked once a year by a qualified service technician.

All installation and service of these units must be performed by a qualified installation and service agency.

Before any service, BE SURE TO TURN OFF GAS AT THE MANUAL SHUT-OFF VALVE AHEAD OF THE COMBINATION GAS CONTROL AND TURN OFF ALL ELECTRIC POWER TO THE HEATER.

General Unit

When providing annual maintenance for the unit heater, keep the unit free from dust, dirt, grease and foreign matter. Pay particular attention to:

1. The combustion air and exhaust vent piping.

2. The burner ports and pilot burner orifices (avoid the use of hard, sharp instruments capable of damaging surfaces for cleaning these ports). To check the burner port and pilot burner orifice, see “Burner and Pilot Assembly Removal”.

3. The air shutters and main burner orifices (avoid the use of hard, sharp instruments capable of damaging surfaces for cleaning these orifices). To check the air shutters and main burner orifices, see for “Manifold Assembly Removal.”

4. The heat exchanger. Clean tubes from the bottom with a

stiff non-wire brush.

5. The heat exchanger should be checked annually for cracks and discoloration of the tubes. If a crack is detected, the heat exchanger should be replaced before the unit is put back into service. If the tubes are dark gray, airflow across the heat exchanger should be checked to insure that a blockage has not occurred or the blower is operating properly.

Electrical Wiring

The electrical wiring should be checked annually for loose connections or deteriorated insulation.

Gas Piping & Controls

The gas valves and piping should be checked annually for general cleanliness and tightness.

The gas controls should be checked to ensure that the unit is operating properly.

Propeller Assembly

Check the motor for lubrication if the motor is not permanently lubricated. Inspect the fan for damage and fit on motor shaft. Clean any dust, dirt or foreign matter from the fan blades.

Blower Assembly

The blower assembly includes the bearings, drive sheaves and belts. Blower bearings should be checked and lubricated based

on the blower manufacturer’s recommendations. Bearings

should also be checked for any unusual wear and replaced if needed.

Drive sheaves should be checked at the same time the bearings are inspected. Check to make sure the sheaves are in alignment and are securely fastened to the blower and motor shafts.

Belt tension should be rechecked shortly after the unit has been installed to check for belt stretching. After the initial start-up, monthly checks are recommended.

Manifold Assembly Removal

To remove the manifold:

1. Shut off gas and electric supply.

2. Lower bottom pan to expose burner and manifold (see Figure 16.2).

3. Disconnect pilot tubing and thermocouple lead (or ignition cable) at the combination gas control (and ignition control).

4. Disconnect control wires for the combination gas control.

5. Disconnect gas manifold at ground union joint.

6. Remove the 2 screws holding the manifold to the heat exchanger support.

7. Clean the orifices and adjust the air shutters as necessary.

8. Follow steps 2-6 in reverse order to install the manifold assembly.

9. Turn on the electric and gas supply.

10. Check the ground union joint for leaks with a soap solution. Tighten if necessary.

Burner and Pilot Assembly Removal

To remove the burner:

1. Shut off gas and electric supply.

2. Lower bottom pan to expose burner and manifold (see

Figure 16.2).

3. Disconnect pilot tubing and thermocouple lead (or ignition

cable) at the combination gas control (and ignition control).

4. Remove the 2 burner retaining pins holding the burner in

place. The burner can then be easily lowered from the unit.

5. Examine the burner and pilot assembly for cleanliness
