1. Open windows

2. Don't touch electrical switches.

3. Extinguish any open flame.

4. Immediately call your gas supplier.

FOR YOUR SAFETY

The use and storage of gasoline or other flammable vapors

and liquids in open containers in the vicinity of this appliance

is hazardous.

THIS MANUAL IS THE PROPERTY OF THE OWNER.

PLEASE BE SURE TO LEAVE IT WITH THE OWNER WHEN

YOU LEAVE THE JOB.

All models approved for use in California by the CEC (when

equipped with IPI), in New York by the MEA division, and in

Massachusetts. Unit heater is certified for non-residential

applications.

CAUTION

To prevent premature heat exchanger failure do not locate

ANY gas-fired units in areas where chlorinated, halogenated

or acid vapors are present in the atmosphere.

Inspection on Arrival

1. Inspect unit upon arrival. In case of damage, report

immediately to transportation company and your local

Modine sales representative.

Check rating plate on unit to verify that power supply meets

available electric power at the point of installation.

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.

INSTALLATION Product Description Combustion Air Requirements Modine PSH and BSH model unit heaters are listed as separated combustion unit heaters and are defined as follows: A unit heater for installation in non-residential structures which, when connected to a sealed combustion air pipe and sealed exhaust vent, supplied by the installer, constructed so that when installed according to the manufacturer’s instructions, air for combustion is derived from the outside atmosphere and the flue gases from the a
PAGE 4
INSTALLATION Figure 2 Suspension Methods 4. Install the vent and combustion air pipes with a downward slope from the appliance of 1/4 inch per foot and suspend securely from overhead structures at points no greater than 3 feet apart. Fasten individual lengths of vent together with at least three corrosion resistant sheet metal screws. 5. Keep the vent pipe at least 6 inches from combustible material.
PAGE 5
INSTALLATION Venting Instructions for Concentric Vent Options The concentric vent concept allows for the vent pipe and the combustion air pipe to pass through one hole in an EXTERIOR wall or roof. The concentric vent kits offered are horizontal or vertical. Venting with 2 pipes; a combustion air pipe and flue product vent pipe remains an option, primarily for replacement heaters where two holes through the exterior of a building already exist.
PAGE 6
INSTALLATION 8. Place this assembly (the adapter box, vent pipe and combustion air pipe) through the wall or roof and verify that the distance requirements as defined in the following sections are met. Securely attach the assembly (adapter box and vent and combustion air pipe) to the wall or roof using appropriate fasteners. 1. The vent must terminate with a Gary Steel Model 1092 or Briedert Type L cap for the appropriate pipe size. 2.

INSTALLATION 6. Provide a drip pocket before each unit and in the line where low spots cannot be avoided. (See Figure 7). 7. Take-off to unit should come fro top or side of main to avoid trapping condensate. 8. Piping, subject to wide temperature variations, should be insulated. 9. Pitch piping up toward unit at least 1/4" per 15' of horizontal run. 10. Compounds used on threaded joints of gas piping must be resistant to action of liquefied petroleum gases. 11.

OPERATION from the factory set performance. The drive number on the unit may be identified by referring to the Power Code number on the serial plate of the unit (see page 23 for model number nomenclature) and matching that number with those shown on page 25. From the listing the drive number can be determined. 8. Blower sheave and motor sheave should be measured to assure correct drive is on unit. Refer to page 25 for drive sizes.

Pilot Flame Adjustment CHECKING INPUT RATE The pilot is orificed to burn properly with an inlet pressure of 67" W.C. on natural gas and 11-14" 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.

TROUBLESHOOTING GUIDE 2. Yellow Tipping. Yellow tipping of a normally blue flame is caused by insufficient primary air, and indicates incomplete combustion producing carbon monoxide ethylene, aldehyde, and fee carbon (soot). A dirty orifice or one that is out of line, can also reduce primary air and cause yellow tipping. Check main burner orifices, clean, realign, or replace if necessary. With propane gas, some yellow tipping is always present, but is not objectionable. 3. Flashback.

TROUBLESHOOTING GUIDE 2. Pilot lights, main burner will not light. Possible Cause 3. Burner shuts down before thermostat is satisfied. Possible Remedy Possible Cause 2a. Gas valve in off off position. 2a. Turn to on position. 2b. System in lock-out mode. 2b. Reset system. 2c. Cracked or broken sensor ceramic. 2c. Replace sensor. 2d. Defective or loose connections to flame sensor or flame sensor lead. 2d. Correct or replace. 2e. Incorrect gas pressure. 2e.
