INSTALLATION
SPECIAL PRECAUTIONS
THE INSTALLATION AND MAINTENANCE INSTRUCTIONS IN THIS MANUAL MUST BE FOLLOWED TO PROVIDE SAFE, EFFICIENT AND TROUBLE-FREE OPERATION. IN ADDITION, PARTICULAR CARE MUST BE EXERCISED REGARDING THE SPECIAL PRECAUTIONS LISTED BELOW. FAILURE TO PROPERLY ADDRESS THESE CRITICAL AREAS COULD RESULT IN PROPERTY DAMAGE OR LOSS, PERSONAL INJURY, OR DEATH.
1. Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage. All units must be wired strictly in accordance with wiring diagram furnished with the unit.
2. Turn off all gas before installing unit heaters.
3. Gas pressure to unit heater controls must never exceed 14” W.C. (1/2 psi).
When leak testing the gas supply piping system, the unit and its combination gas control must be isolated during any pressure testing in excess of 14’ W.C. (1/2 psi).
The unit should be isolated from the gas supply piping system by closing its field installed manual shut-off valve.
4. Check gas inlet pressure at unit upstream from the combination gas control. The inlet pressure should be 6”-7” W.C. on natural gas or 12”-14” W.C. on propane gas. Purging of gas piping should be performed as described in ANSI Z223.1 Latest Edition, or in Canada in CAN/CGA-B149 codes.
5. All units must be vented to the outside atmosphere.
6. Do not install in potentially explosive or flammable atmospheres laden with grain dust, sawdust, or similar air-borne materials. In such applications a blower type heater installed in a separate room with ducting, including appropriate back flow prevention dampers, to the dust-laden room is recommended.
7. Installation of units in high humidity or salt water atmospheres will cause accelerated corrosion resulting in a reduction of the normal life span of the units.
8. To prevent premature heat exchanger failure do not locate ANY gas-fired unit in areas where chlorinated, halogenated or acid vapors are present in the atmosphere.
9. 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.
10. Do not locate units in tightly sealed rooms or small compartments without provision for adequate combustion air and venting. Combustion air must have access to the confined space through a minimum of two permanent openings in the enclosure, at least one near the bottom. They should provide a free area of one square inch per 1000 BTU per hour input rating of the unit with a minimum of 100 square inches for each opening, whichever is greater.
11. Do not install unit outdoors.
12. For all sizes, minimum clearance to combustibles from the bottom is 12 inches and from the sides 18 inches; for sizes 30-100 from the top is 1 inch and from the vent connector 2 inches; for sizes 125­300 from the top is 2 inches and from the vent connector 3 inches; and for sizes 350 & 400 from the top is 3 inches and from the vent connector 6 inches.
13. Allow at least 6” clearance at the sides and 12” clearance at rear (or 6” beyond end of motor at rear of unit, whichever is greater) to provide ample air for combustion and proper operation of fan.
14. The minimum distance from combustible materials based on the combustible material surface not exceeding 160°F. Clearance from the top of the unit may be required to be greater than 6” if heat damage, other than fire, may occur to materials above the unit heater at the temperature described.
15. Do not install units below 7 feet measured from the bottom of the unit to the floor.
16. Modine unit heaters are designed for use in heating applications with ambient temperatures between 32° F and 90° F If an application exists where ambient temperatures can be expected to fall outside of this range, contact factory for recommendations.
17. Provide clearance for opening hinged bottom for servicing. See Figure 1A. Do not set unit on its bottom.
18. To assure that flames do not impinge on heat exchanger surfaces, the unit must be suspended in a vertical and level position. Failure to suspend unit properly may shorten the life of the unit heater.
19. Do not lift unit heater by gas controls, gas manifold, or power venter.
20.
Be sure no obstructions block air intake and discharge of unit heater.
21. Do not attach duct work, air filters, or polytubes to any propeller (PAE) model unit heaters.
22. In aircraft hangars, keep the bottom of the unit at least 10’ from the highest surface of the wings or engine enclosure of the highest aircraft housed in the hangar and in accordance with the requirements of the enforcing authority and/or NFPA No. 409 – Latest Edition .
23. In garages or other sections of aircraft hangars such as offices and shops which communicate with areas used for servicing or storage, keep the bottom of the unit at least 7’ above the floor. In public garages, the unit must be installed in accordance with the Standard for Parking Structures NFPA #88A and the Standard for Repair Garages NFPA #88B. In Canada, installation of unit heaters in airplane hangars must be in accordance with the requirements of the enforcing authority, and in public garages in accordance with the current CAN/CGA-B149 codes.
24. Consult piping, electrical, and venting instructions in this manual before final installation.
25. All literature shipped with your unit should be kept for future use for servicing or service diagnosis. Do not discard any literature shipped with your unit.
26. Gas-fired heating equipment which has been improperly vented, or which experiences a blocked vent condition may have the flue gases accidentally spilled into the heating space. See page 20 for specific information about the blocked vent safety switch supplied on the unit.
27.
When servicing or repairing this equipment, use only Modine approved service replacement parts. A complete replacement parts list may be obtained by contacting Modine Manufacturing Company. Refer to the rating plate on the unit for complete unit model number, serial number and company address. Any substitution of parts or controls not approved by Modine will be at owners risk.

INSTALLATION
!
!
In the U.S., the installation of these units must comply with the “National Fuel Gas Code,” ANSI Z223.1, latest edition (also known as NFPA 54) and other applicable local building codes.
In Canada, the installation of these units must comply with local plumbing or waste water codes and other applicable codes and with the current code CAN/CGA-B149.1, “Installation Code for Natural Gas Burning Appliances and Equipment” or CAN/CGA-B149.2, “Installation Code for Propane Burning Appliances and Equipment.”
1. Alliinstallation and service of these units must be performed by a qualified installation and service agency only as defined in ANSI Z223.1, latest edition or in Canada by a licensed gas fitter.
2. This unit is certified by A.G.A. and by C.G.A., with the controls furnished. For replacement parts, submit the complete model and serial numbers shown on rating plate on the unit. Modine reserves the right to substitute other authorized controls as replacements.
3. Unit is balanced for correct performance. Do not alter fan or operate motors at reduced speed.
4. Information on controls is supplied separately.
5. Modine unit heaters use the same burner for natural and propane gases.
Locating Unit Heaters
CAUTION
Units must not be installed in potentially explosive, flammable or corrosive atmosphere.
To prevent premature heat exchanger failure do not locate ANY gas-fired unit in areas where chlorinated, halogenated or acid vapors are present in the atmosphere.
In locating units, consider general space-heating requirements, availability of gas, and proximity to vent locations. Unit heaters should be located so heated air streams wipe exposed walls without blowing directly against them. In multiple unit installations, arrange units so that each supports the air stream from another, setting up circulatory air movement in the area, but maintain separation between units so discharge from one unit will not be directed into the inlet of another. In buildings exposed to prevailing winds, a large portion of the heated air should be directed along the windward wall. Avoid interference of air streams as much as possible.
Mounting height (measured from bottom of unit) at which unit heaters are installed is critical. Maximum mounting heights are listed in Table 7 on page 18. Alternate mounting heights for units with deflector hoods or nozzles are shown on pages 14,16 and 17. The maximum mounting height for any unit is that height above which the unit will not deliver heated air to the floor.The maximum mounting heights must not be exceeded in order to assure maximum comfort.
Modine unit heaters are designed for use in heating applications with ambient temperatures between 32° F and 90° F. If an application exists where ambient temperatures can be expected to fall outside of this range, contact factory for recommendations.
Combustion Air Requirements
Units installed in tightly sealed buildings or confined spaces should be provided with two permanent openings, one near the top of the enclosure 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 of all units in the enclosure, freely communicating with interior areas having, in turn, adequate infiltration from the outside.
Unit Suspension
Be sure the means of suspension is adequate to support the weight of the unit. (See page 12 for unit weights.) For proper operation, the unit must be installed in a level horizontal position. Clearances to combustibles as specified above must be strictly maintained. Do not install standard unit heaters above the maximum mounting height shown in Table 7 on page 13, or below seven feet from the bottom of the unit to the floor.
CAUTION
For all sizes, minimum clearance to combustibles from the bottom is 12" and from the sides 18"; for PAE sizes 30-100 from the top is 1" and from the vent connector 2"; for PAE sizes 125-300 from the top is 2" and from the vent connector 3"; for PAE sizes 350 & 400 from the top is 3" and from the vent connector 6”; and for all BAE sizes from the top and vent connector is 6".
Allow at least 12" at the rear, or 6" beyond the end of the motor (whichever is greater), to provide ample air for combustion and for proper operation of fan. Provide clearance for opening of the hinged bottom for servicing – SEE FIGURE 1A.
On all propeller units, except the PAE 300, PAE 350 and PAE 400, two tapped holes (3/8-16) are located in the top of the unit to receive ceiling hangers.
Units with two point suspension, models PAE30 through PAE250, incorporate a level hanging feature. Depending on what options and accessories are being used, the heater may not hang level as received 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. These preliminary adjustments need to be made with the heater resting on the floor.
PAE30 through PAE250 units without deflector hoods that do not hang level after being installed, can be corrected in place. Simply remove both outer side panels (screws to remove are on back flange of side panel) and you will see the (adjustable) mounting brackets (Fig. 2). Loosen the set screws holding the mounting brackets in place and using a rubber mallet or something similar, tap the heater into a position where it does hang level. Re-tighten set screws and replace the outer side panels
The PAE 300, PAE 350 and PAE 400 have four mounting holes. On all blower units, except the PAE 300, PAE 350 and PAE 400, two tapped holes are provided in the top of the unit and two holes in the blower support bracket. The PAE 300, PAE 350 and PAE 400 have four tapped holes in the top of the unit and two in the blower support bracket for mounting. exchanger tubes, unit must be supported in a vertical position, with suspension hangers “UP.” Check with a level. This is important to the operation and life of unit.
Note accessories from Modine. The hardware allows for pipe caps to be secured into the top of the unit heater with machine screws (as illustrated - machine screws are 3/8 - 16 x 1.75 UNC-2A THD). The pipe caps can then accommodate 3/4" NPT pipe for mounting. Three different kits are available with either 2, 4, or 6 adapters per kit. See price sheet to determine proper kit.

Select size of vent pipe to fit vent pipe connection at rear of appliance (see Page 12, Dimension J). (Exception: All PAE/BAE 50 models with two-stage or modulating controls must use a 5 inch vent.) Do not use a vent pipe smaller than the vent pipe connection on the unit. Vent pipe should be galvanized steel or other suitable corrosion-resistant material. Follow the National Fuel Gas Code for minimum thicknesses of vent material; minimum thicknesses for vent connectors vary depending on pipe diameter.

For best venting, put as much vertical vent as close to the unit as possible. Fasten individual lengths of vent together with at least three corrosion-resistant sheet-metal screws.
does pass through an unheated space, Modine recommends the use of Type B double wall vent. If single wall vent is used, insulate vent runs greater than 5 feet to minimize condensation. Use insulation that is noncombustible with a rating of not less than 350°F. Install a tee fitting at the low point of the vent system to provide a drip leg with a clean out cap as shown in Figure 3. The drip leg should be cleaned annually.
(see page 2, section 12 for allowable reductions). For double wall vent pipe, maintain clearances listed on vent pipe (Category I and II units). The minimum distance from combustible material is based on the combustible material surface not exceeding 160°F. Clearance from the vent connector, vent, or top of unit may be required to be greater than the minimum clearance if heat damage other than fire (such as material distortion or discoloration) may occur.
thimble 4 inches greater than the vent diameter is necessary. If there is 6 feet or more of vent pipe in the open space between the unit and where the vent pipe passes through the floor or roof, the thimble need only be 2 inches greater than the diameter of the vent pipe. If a thimble is not used, all combustible material must be cut away to provide the specified clearance to combustibles. Any material used to close the opening must be noncombustible.
Top of vertical vent should extend at least two feet above the highest point where it passes through a roof and at least 2 feet higher than any portion of a building within a horizontal distance of 10 feet (see Figure 3).

CAUTION
Gas pressure to unit heater controls must never exceed 14" W.C. (1/2 psi).
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).
The appliance should be isolated from the gas supply piping system by closing its field installed manual shut-off valve.
1. Installation of piping must be in accordance with local codes, and ANSI Z223.1, “National Fuel Gas Code,” or CAN/CGA-B149 in Canada.
2. Piping to units should conform with local and national requirements for type and volume and gas handled, and pressure drop allowed in the line. Refer to Table 4, 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 1. 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 1 allows for the usual number of fittings with a 0.3” W.C. pressure drop. Where the gas supplied has a specific gravity other than 0.60, apply the multiplying factor as given in Table 2.
3. After threading and reaming the ends, inspect piping and remove loose dirt and chips.

Do not attempt to attach ductwork of any kind to propeller PAE models.
Burned-out heat exchanger as well as shorter equipment life will result from not providing uniform air distribution.
When installing heater always follow good duct design practices for even distribution of the air across the heat exchanger. Recommended layouts are shown below. When installing blower units with ductwork the following must be done.
P
rovide uniform air distribution over the heat exchanger.
1. Use turning vanes where required. See figures below.
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 Modine blower enclosure kit or if using field designed enclosure maintain dimensions of blower enclosure as shown on page 12.
CAUTION
Check for red heat exchanger tubes. If bottom of tubes become red while blower unit is in operation, check for proper air volume and air distribution. Adjust blower speed or correct discharge duct design to correct problem.

Installation of Blower Models (BAE UNITS)
Determining Blower Speed
The drive assembly and motor on all gas-fired blower unit heaters are factory assembled. The adjustable motor sheave has been pre-set to permit operation of this unit 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 pages 18 and 19 and the temperature rise range shown on the unit’s rating plate.
To determine the proper blower speed and motor sheave turns open, the conditions under which the unit is to operate must be known. If the blower unit is to be used without duct work, nozzles or filters, the only criteria for determining the motor sheave turns open and blower speed is the amount of air to be delivered. The performance tables for blower models are shown on pages 18 and 19. As an example, a model BAE 350 unit, operating with no external static pressure, that is, no duct work, nozzles, etc., and is to deliver an air volume of 6481 cfm (cfm = cubic feet of air per minute) requires that the unit be supplied with a 5 hp motor, a C116 drive, and the drive sheave must be set at 3 turns open to achieve a blower speed of 940 rpm (see performance table for units with or without blower enclosure, page 18). See "Blower Adjustments" on page 8 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. This resistance is called pressure loss. The total of the pressure losses must be determined before adjusting the blower speed.
If Modine filters are used, the expected pressure loss through the filters is included in the performance data on page 19. If Modine supplied discharge nozzles are used, the expected pressure drop of the nozzles can be found footnoted at the bottom of page 14. 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, let's say, a model BAE 350 is to be used with a Modine supplied blower enclosure and Modine supplied filters attached to someone else's ductwork. The unit is to move 6481 cfm or air flow against an external static pressure of 0.2" W.C. Entering the performance table on page 19 (Blower models with filters) for a BAE 350, at 6481 cfm and 0.2" W.C. static pressure, it is seen that the unit will require a 5 hp motor using a C116 drive, and the motor sheave should be set at .5 turns open to achieve a blower speed of 1055 rpm. You can see this example differs from similar conditions in paragraph 2 by the number of turns open and a higher rpm, which is needed to overcome the added external static pressure from the filters.

2. Adjust motor adjusting screw for a belt deflection of approximately 3/4" with five pounds of force applied midway between the sheaves (refer to Figure 6a). 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.
3. 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.
4. Make electrical connections according to the wiring diagram.
5. Check rotation of the blower. Motor should be in clockwise rotation when facing motor pulley. If rotation is incorrect, correction should be made by interchanging wiring within the motor. See wiring diagram on the motor.
6. The actual current draw of the motor should be determined. Under no condition should the current draw exceed that shown on the motor rating plate.

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 pages 18 and 19. 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.
Shut-off power before making blower speed adjustments.
1. Refer to Determining Blower Speed on page 7 and to Blower Drive Selection on pages 18 and 19 to determine proper blower RPM.
2. Loosen belt and take belt off of motor sheave.
3. Loosen set screw on outer side of adjustable motor sheave (see Figure 6).
4. To reduce the speed of the blower, turn outer side of motor sheave counterclockwise.
Figure 6 Motor Sheave Adjustment
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 6a). Since the belt tension will decrease dramatically after an initial run-in period, it is necessary to periodically re-check the tension to assure continual 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 pages18 and19 to assure actual desired air flow is being achieved.
11.If adjustments are required, recheck motor amps after final blower speed adjustment.

OPERATION
CAUTION
Start-up and adjustment procedures should be performed by a qualified serviceman.
Check the gas inlet pressure at the unit upstream of the combination gas control. The inlet pressure should be 6"-7" W.C. on natural gas or 12"-14" W.C. on propane. If inlet pressure is too high, install an additional pressure regulator upstream of the combination gas control.
The pilot flame must be adjusted as described below. Purging of air from gas lines, piping, and lighting the pilot should be pe rfo rmed as des cri be d in A NSI Z22 3. 1-l atest edi tion “National Fuel Gas Code” (CAN/CGA-B149 in Canada).
Be sure no obstructions block air intake and discharge of unit heater.
Prior to Operation
Although this unit has been assembled and fire-tested at the factory, the following pre-operational procedures should be performed to assure proper on-site operation:
1. Turn off all electric power to the unit.
2. Check burner to insure proper alignment.
3. Check fan clearance. Fan should not contact casing when spun by hand.
4. Check all electrical connections to be sure they are secure.
5. If you are not familiar with the unit’s controls (i.e. combination gas control), refer to the control manufacturer’s literature supplied with the unit.
6. Check that all horizontal deflector blades are open a minimum of 30° as measured from vertical.

A
fter Initial Start Up
1. Check pilot flame adjustment as discussed below.
2. Check gas piping for leaks with a soap bubble solution to
insure safe operation.
3. Check gas input rate to assure proper gas flow and
pressure.
Figure 7 Correct Pilot Flame
The pilot burner is orificed to burn properly with an inlet pressure of 6-7" W.C. on natural gas and 12-14" W.C. on propane gas, but final adjustment must be made after installation. Adjust to have 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. Normally this flame will produce satisfactory results. To adjust flame use pilot adjustment screw on combination gas control (for location, see the combination gas control literature supplied with unit). If the pilot flame is longer and larger than shown by Figure 7, it is possible that it may cause soot and/or impinge on the heat exchanger causing burnout. 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.

Gas Flame Control
Control of burner flames on units utilizing natural gas is achieved by moving the gas manifold to either increase or decrease primary combustion air. Prior to flame adjustment, operate unit with casing closed for about five minutes. Operation can be viewed after loosening and pushing aside the blue gas designation disc on rear of unit.

Heater Parts from ACF Greenhouses
OPERATION
Lack of primary air will cause soft yellow-tipped flames. Excess primary air produces short, well-defined flames with a tendency to lift off the burner ports. Proper operation with natural gas provides a soft blue flame with a well-defined inner core.
To increase primary air, loosen the manifold mounting screws and tap the manifold away from the mixer tubes until yellow­tipped flames disappear. See Figure 14. To decrease primary air move the manifold closer to the mixer tubes until flames no longer lift from burner ports, but being careful not to cause yellow tipping. Retighten manifold mounting screws after adjustment.
P
ropane Gas Flame Control
Adjustable primary air shutters are attached to the orifices on the gas manifold for units equipped for propane gas operation. See Figure 15. Prior to flame adjustment, operate unit heater with casing closed for at least five minutes. Then lower hinged bottom and adjust primary air shutters. Loosen wing screws and push shutters forward to reduce primary air until yellow flame tips appear. Then increase primary air until yellow tips diminish to just a slightly yellow tip and a clean blue flame with a well­defined inner cone appears.
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.

Checking Input Rate
CAUTION
Check the gas inlet pressure at the unit upstream of the combination gas control. The inlet pressure should be 6"-7" W.C. on natural gas or 12"-14" W.C. on propane. If inlet pressure is too high, install an additional pressure regulator upstream of the combination gas control.
Important checked with unit in operation when making final adjustments.
I
nput Adjustments
The gas pressure regulator (part of the combination gas control) is adjusted at the factory for average gas conditions. It is important that gas be supplied to the heater in accordance with the input rating stamped on the serial plate. Actual input should be checked and necessary adjustments made after the heater is installed. Over-firing, a result of too high an input, reduces the life of the unit, and increases maintenance. Under no circumstances should the input exceed that shown on the rating plate.
Input can be determined by the meter-timing method provided other gas equipment connected to the meter is off during the test. If this is not possible, use the pressure method.
(
A) Meter Timing Method
1. Shut off all other gas-burning equipment, including other pilot lights served by the gas meter.
2. Start the heater and determine the number of seconds it takes to consume 1 cu. ft. of gas. Two basic formulas are useful:
– Inlet pressure and manifold pressure must be
F1 = 3600 C/T
F2 = F1/C
where:
F1 = input to heater, Btuh.
F2 = input to heater, cu. ft. per hr.
C = heating value of gas, Btu per cu. ft.
T = time to consume 1 cu. ft. of gas in sec.
The heating value of gas may be determined from the local utility or gas dealer.
These are representative values:
GAS
Natural 1000-1150
Propane 2500
3.
If the seconds for 1 cu. ft. are more (input less) than shown in
.
Table 5 for model being tested, locate the combination gas control and pressure regulator adjustment screw (see Figure
8). Remove the cap screw from the pressure regulator and make one clockwise turn at a time on the adjustment screw until the correct time is obtained. If the seconds are less (input greater) than indicated in the table, follow the same procedure
c
ounter-clockwise
in a
If the correct number of seconds cannot be obtained check orifice size. Correct orifices can be obtained from Modine Manufacturing Company, Buena Vista, Virginia. When requesting orifices, state type of gas, heating value, and its specific gravity. Also give model number of unit.
For example, if the input to the heater is 100,000 Btuh and the heating value of the gas is 1000 Btu per cu. ft., then, by the second formula, the input is 100 cu. ft. per hr. Table 4 indicates the time for one revolution of various size meter dials with various input rates. If a 1 cu. ft. meter dial is used, we proceed down the cu. ft. column to 100 cu. ft. per hr. and then horizontally to the left to determine a time of 36 seconds for one revolution of the dial. Similarly, if the 1/2 cu. ft. dial is used, we determine a time of 18 seconds for one revolution at the required input.
Btu per cu. ft.
direction.
(B) Pressure Method
The pressure method determines input by measuring the pressure of the gas in the manifold in inches of water.
1. Determine correct manifold pressure from Table 4.
2. Locate combination gas control.
3. Move gas control knob (or lever) to off.
4. Remove the 1/8" pipe plug in outlet pressure tap in combination gas control (see Figure 9) and attach water manometer or “U” tube which is at least 12" high.
5. Follow lighting instructions and turn thermostat up to get unit to fire.
6. If pressure as indicated by “U” tube is less than 1/2" higher or lower than indicated in Table 4, adjust regulator as described under “Meter-Timing Method,” Step 3.
If pressure as indicated by “U” tube is more than 1/2" higher or lower than indicated in Table 4, check inlet pressure at unit. The inlet pressure should be 6"-7" W.C. pressure on natural gas and 12"-14" W.C. on propane gas.
After adjustment move gas control knob (or lever) to off and replace 1/8" pipe plug. With the plug in place, follow the lighting instructions to put unit back in service.

The above table is based on an inlet air temperature of 70°F and an air temperature rise of 55°F. Air deflectors on, 40° and 90° discharge nozzles set perpendicular to the face of the air discharge opening. On 5-way nozzles all air deflectors set perpendicular to floor. Static pressure measured at 0.1" W.C. for 90° nozzle, 0.2" W.C. for 40° downward and 5-way nozzle, and 0.3" W.C. for 40° splitter nozzle. Outlet velocities are approximately 1750 FPM for the 40° nozzles, 1000 FPM for the 90° nozzle and 1300 FPM for 5-way. For motor size, drive and blower rpm refer to pages 18 and 19. Mounting height measured from bottom of unit.

Limit Control (Overheat Switch)
The limit control, mounted on the left inner side panel (when facing front of unit), will shut off the gas supply to the main burner in the event of overheating. It is a single pole single throw switch. The contacts open to shut the electric gas valve off in the event the unit should overheat. This limit control should operate only when something is seriously wrong with the unit. Anytime this control operates, correct the difficulty immediately or serious damage may result. If the limit control cuts off the gas supply during normal operation:
1. Make sure deflector blades are open and that there are not any obstructions in the air inlet or discharge outlet.
2. Check actual input to unit against rated input.
3. Check to be sure motor is operating.
4. On propeller units, check that fan is not loose on motor shaft. On blower units, check belt and sheave for tightness or damage.
5. On propeller units, check fan speed against speed on motor nameplate. On blower units check blower speed against Performance Data on pages 18 or 19, check for restriction in ducts and for dirty filters.
6. Check to make sure the venting system is not damaged or blocked. Also check to be sure unit is venting normally and that there is not negative pressure in the building adversely affecting draft.
7. Clean heat exchanger tubes inside and out if necessary.
8. If items 1-7 do not solve the problem, check limit control and replace if necessary. The control is accessible by removing

MPORTANT NOTE:
The limit control (overheat switch) on this unit heater will shut off the gas should excessive discharge temperatures occur. Do not attempt to control the fan with the limit control. Any change in wiring to attempt to control the fan with the limit control will result in hazardous conditions and void the warranty.
Blocked Vent Safety Switch (BVSS)
A BVSS is supplied on all gravity-vented unit heaters and is designed to prevent operation of the main burner if the venting system is blocked.
If the BVSS has tripped, turn off the gas and electric supply to the unit heater. Check the entire vent system connected to the unit heater for blockage or damage.
In the case of a restricted vent, there may not be enough dilution air to carry away the heat radiating off the heat exchanger top (and surrounding area), the BVSS may exceed the temperature setting and trip.
Spillage will also cause the BVSS to trip. If spillage exceeds five minutes, even though the vent is in compliance with the NFGC, some type of change must be made in the vent system to stop the spillage. These changes (improvements) could be lengthening the vertical vent run, reducing the horizontal vent run, insulating the vent pipe, using a larger diameter vent pipe, or using a less restrictive vent terminal.
If these changes do not stop the spillage or the installer

and adjustment.
(3) Checking cleanliness of blower wheel and filters.
2. Keep unit free from dust, dirt, grease, and foreign matter, paying particular attention to:
a. Combustion air inlets.
b. Burner ports, pilot burner, and main burner orifices
(
avoid use of hard, sharp instruments capable of damaging surfaces, for cleaning these ports.) pressure is abailable, use air hose to blow dirt and other foreign matter from within the burner. Also main burner orifices should be checked for blockage due to spider webs, etc.
If air
c. Primary air shutters (when used).
d. Clean heat exchanger tubes from bottom with stiff brush
after removing burner (Do not use wire brush).
e. Bottom pan.
f. Fan blade.
3. Check wiring for possible loose connections.
4. Controls – See control instruction sheets furnished separately with the unit heater.

Combustion Problem Symptoms and Diagnosis
To realize full gas heating value requires periodic inspections with proper combustion control corrections as outlined and illustrated here.
. Lifting Flames
1
Lifting flames rise unevenly above the burner port and may occur on few or all the ports. Sometimes the flames drop and lift intermittently. Lifting can be eliminated by reducing primary air. If flame cannot be adjusted properly, check input rate to heater and manifold gas pressure; reduce if necessary. Check the orifice size with those listed in Table 5 to be sure the unit is not operating over rated input.

2. Yellow Tipping
Yellow tipping of a normally blue flame is caused by insufficient primary air, and indicated incomplete combustion producing carbon monoxide, aldehydes, and free carbon (soot). A dirty orifice or one that is out of line, can also reduce primary air and cause yellow tipping. Check orifice, clean realign, or replace if necessary. With propane gas, some yellow tipping is always present, but is not objectionable.
3. Flashback
Flashback occurs when air-gas mixture ignites inside the burner to burn near the orifice. Flashback on ignition or during burner operation usually can be eliminated by reducing primary air. The burner may also be operating below its rated capacity. Check input rate and adjust to correct value by increasing orifice size or manifold gas pressure.
. Wavering Flames
4
Drafts across burners may cause flames to waver or appear unstable. Wavering flames can lead to incomplete combustion if flames impinge on cool surfaces. Wavering can be caused by air drafts into the burner compartment or by misalignment of the burner. Draft-blown flames may indicate a cracked heat exchanger.
Figure 17 Wavering Flame or Misalignment
5. Floating Flames
Floating flames are long – do not have well-defined cones, roll around in the combustion chamber, sometimes completely off the ports. Usually an aldehyde odor is present to indicate incomplete combustion. If combustion air supply is reduced too far, burner flames will float. Often the pilot flame near the port smothers and goes out. Lack of combustion air causes burner flames to float. The unit may be overfired so its flue outlet area may be too small for the increased firing rate. Check input rate and reduce if necessary. Soot or dust may be blocking the flue. Check flue and clear any blockage. Adjust primary air to get rid of yellow tipping that may produce soot to block flueways. Make sure combustion air inlets are
not blocked.
Figure 18 Floating Flame Condition
6. Flame Rollout
Flames rolling out of the combustion air inlets when the burner is turned on can create a fire hazard, scorch unit finish, burn wires, or damage controls. Gas in the burner mixer may be ignited, producing flashback. Flame rollout is a variation of floating flames, with flames reaching for air outside the combustion chamber. Basic cause is lack of combustion air that may be due to overfiring, poor venting, or flue blockage.
Figure 19 Flame Rollout Appearance
Standing Pilot Problem Symptoms and Diagnosis
1. If pilot does not light:
POSSIBLE CAUSES AND REMEDIES
1a. Check that manual gas control (knob or lever) on
combination gas control is in the pilot position.
1b. Bleed air from pilot line. (Use special care in bleeding
propane units.)
1c. If pilot sputters, check pilot line for condensate or other
obstruction.
1d. If pilot flame is feeble or short, check pilot orifice for
cleanliness. Replace if necessary. See page 9 for pilot flame adjustment.
1e. Be sure thermocouple contact point is clean. If problem
persists, replace thermocouple.
1f. If the above steps do not correct the condition, consult
your local qualified installation and service contractor or appropriate utility company.
. If standing pilot does not stay lit:
2
POSSIBLE CAUSES AND REMEDIES
2a. Check inlet pressure with all units operating, making
certain that there is proper pressure.
2b. Check pipe or tubing size to unit. See Table 1.
2c. Be sure all pilot connections are tight.
2d. Check for excessive drafts.
2e. Check for clogged pilot orifice or pilot line.
2f. Check for leaks around pilot fittings. If leaks cause flame
impingement on thermocouple lead, thermocouple may become inoperative.
23
Heater Parts from ACF Greenhouses
TROUBLESHOOTING GUIDE
3. Effect of pilot operation on safety controls:
POSSIBLE CAUSES AND REMEDIES
3a. A short pilot flame may cause poor ignition and result in
the controls not opening the combination gas control or reduce heat on thermocouple to the point where the automatic controls become inoperative, thereby shutting off gas supply to main burners. This may result from a plugged orifice.
3b. Check electrical connection from the thermocouple
element to the safety valve to assure good electrical contact. Also check location of pilot flame in relation to thermocouple element.
. If main burners do not light:
4
POSSIBLE CAUSES AND REMEDIES
4a. Check that manual valve on combination gas control is in
ON position.
4b. Be sure pilot is lit, correctly positioned and strong enough
to ignite burner ports.
4c. Check wiring (electrical power supply) to combination gas
control.
4d. If unit is equipped with an ECO (energy cut-off device
located on rear panel of unit) check fuse in ECO and make sure it has not blown and is operating correctly. Caution: The ECO fuse should blow only if excessive unit temperatures are experienced. If fuse is blown make sure the cause of the unit overheating is found and corrected before replacing the fuse and placing the unit back into operation.
4e. If the above does not correct the condition, consult your
local gas company or local Modine representative.

Shaded pole motors on models PAE 30 through PAE 125 – permanent split capacitor motors on models PAE 145 through PAE 400.
Whenever 230V/1φ or 230V/3φ power is used, it is necessary to specify 230V/25V controls. Whenever 460/3φ power is used, it is necessary to specify 230V/24V
controls and in addition, a 460V/230V 75VA step-down transformer (by others) is required (if the power exhauster accessory is used, the step-down transformer by others needs to be 250VA). On 230V/3φ or 460V/3φ systems, the motor starter coil voltage (motor starter by others) must be 230V. For 200V/3φ system, the motor starter coil voltage (motor starter by others) must be 200V.
BAE models – split phase motors 1/4-3/4 hp, capacitor start type motors 1-5 hp. 1/4-5 hp motors – 1725 rpm.
Units with 460V/3φ power supply are not listed by C.G.A.
All motors used are produced, rated and tested by reputable manufacturers in accordance with NEMA standards and carry the standard warranty of both the motor
manufacturer and Modine. All motors are totally enclosed and all single phase motors have built-in thermal overload protection.

C
Single-Stage, Standing Pilot, 100% Shut-Off – thermocouple. Pilot needs to be manually lit initially and stays lit.
Two-Stage, Standing Pilot, 100% Shut-Off – 100% of full rated input) and thermocouple. Pilot needs to be manually lit initially and stays lit. Available on PAE/BAE models only.
Single-Stage, Intermittent Pilot Ignition, 100% Shut-Off with Continuous Retry – stage combination gas control and an ignition control (continuous retry). Pilot is automatically lit on call for heat.
Mechanical Modulation with Automatic Pilot Ignition, 100% Shut-Off with Continuous Retry – a modulating combination gas control and an ignition control (continuous retry). Pilot is automatically lit whenever there is power to the unit. Modulation range is between 50% and 100% fire; gas control shuts off below 50% fire. Available on BAE models only.
wo-Stage, Intermittent Pilot Ignition, 100% Shut-Off with Continuous Retry –
T combination gas control (which fires at 50% or 100% of full rated input) and an ignition control (continuous retry). Pilot is automatically lit only on call for heat. Available on PAE/BAE models only.
Models BAE 50 thru BAE 100 with two-stage or modulating gas controls require a Category II vent system.
For units with control systems having fan timer, fan starts 30 seconds (max.) after ignition and shuts down approximately 60 seconds after main burner shuts down. Available on units with up to 1 hp
motors or 14 amps @ 115V A.C. Contact factory for applications with units having motors with horsepower ratings above 1 hp or 14 amps @ 115V A.C.
Whenever 230V/1φ or 230V/3φ power is used, it is necessary to specify 230V/25V controls. Whenever 460V/3φ power is used, it is necessary to specify 230V/25V controls and in addition, a
460V/230V/75VA step-down transformer (by others) is required (if the power exhauster accessory is used, the step-down transformer by others needs to be 250VA). On 230V or 460V/3φ systems, the motor starter coil voltage (motor starter by others) must be 230V. For 200V/3φ systems, the motor starter coil voltage (motor starter by others) must be 200V.
ontrol Operating Sequence
C
For Standing Pilot (with Pilot Lit)
Upon a call for heat from thermostat, power is supplied to the combination gas control and at the same time power is supplied to the fan timer. The main burner should light immediately. The fan motor will start in 15 to 45 seconds.
When the thermostat has been satisfied, power is turned off to the combination gas control and fan timer. The main burner will go out but the pilot will continue to burn. The fan motor will continue to operate for 45 to 75 seconds to allow the heat exchanger to cool down.
F
or Intermittent Pilot
Upon a call for heat from the thermostat, power is supplied to the ignition control and at the same time power is supplied to the fan timer. Sparking will start at the pilot immediately and at the same time the first operator of the combination gas control opens to allow gas to flow to the pilot burner. The pilot flame should light and be sensed (proven) in a few seconds. As soon as the pilot flame is sensed the sparking will stop and the second operator of the combination gas control will open allowing gas to flow to the main burner. In 15 to 45 seconds from the time the thermostat called for heat the fan motor will start.
On systems utilizing control codes 08 and 09, the ignition control will attempt to light the pilot once the system is turned on. If the pilot is not sensed for any reason, the spark will continue indefinitely until the pilot flame is sensed or until power is interrupted to the system.

Utilizes a two-stage
On systems utilizing control codes 30, 31, 85 or 86 the sequence is similar, except that the system will attempt to light the pilot for 70 seconds once there is a demand for heat. If the pilot is not sensed for any reason, the ignition control will wait for a predetermined time with the combination gas control closed and no spark. After the predetermined time lapses, the cycle will begin again. The time that lapses between cycles is at pre-programmed intervals (approximately 6 minutes). This will continue indefinitely until the pilot flame is sensed or until power is interrupted to the system.
When the thermostat has been satisfied, power is turned off to the ignition control and the combination gas control, so both the main gas and pilot gas are turned off. The fan will continue to operate for 45 to 75 seconds to allow the heat exchanger to cool down.
T
wo-Stage Control Systems
The thermostat will start the unit with the combination gas control in the first stage (50% of normal input). If the thermostat senses a further drop in temperature the second stage (100% of normal input) of the combination gas control will be energized. When the thermostat senses an increase in temperature the combination gas control will be returned to the first stage operation.
M
echanical Modulation Systems
When power is turned on the pilot is automatically lit. When the sensing bulb attached to the combination gas control senses a drop in temperature the valve will open at 50% of normal input. If the temperature drops further the valve will open further. As the temperature rises the valve will return to 50% of normal input. If the temperature rises further the valve will close.
