separated combustion gas-fired unit heaters

model PTS and BTS

6-561.10

5H0801060000

All models approved for use in California by the CEC and in

Massachusetts. Unit heater is certified for non-residential

applications.

FOR YOUR SAFETY

WHAT TO DO IF YOU SMELL GAS:

1. Open windows.

2. Do not try to light any appliance.

3. Do not touch any electrical switch; do not use any

phone in your building.

4. Extinguish any open flame.

5. Immediately call your gas supplier from

a neighbor’s phone. Follow the gas supplier’s

instructions. If you can not reach your gas supplier,

call your fire department.

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.

The use of this manual is specifically intended for a

qualified installation and service agency. All installation

and service of these units must be performed by a

qualified installation and service agency.

1. Improper installation, adjustment, alteration, service,

or maintenance can cause property damage, injury, or

death, and could cause exposure to substances which

have been determined by various state agencies to

cause cancer, birth defects, or other reproductive

harm. Read the installation, operating, and

maintenance instructions thoroughly before installing

or servicing this equipment.

2. Do not locate ANY gas-fired units in areas where

chlorinated, halogenated, or acidic vapors are present

in the atmosphere. These substances can cause

premature heat exchanger failure due to corrosion,

which can cause property damage, serious injury, or

death.

SPECIAL PRECAUTIONS WARNING 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. THESE INSTRUCTIONS ARE SUBJECT TO ANY MORE RESTRICTIVE LOCAL OR NATIONAL CODES. 12.
PAGE 3
SPECIAL PRECAUTIONS / SI (METRIC) CONVERSION FACTORS BEFORE YOU BEGIN CAUTION 16. Purging of air from gas supply line should be performed as described in the National Fuel Gas Code, ANSI Z223.1 (NFPA 54) - latest edition. In Canada, installation must be in accordance with CSA-B149.1. 17. 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). 18.

UNIT LOCATION Figure 4.1 - Combustible Material and Service Clearances UNIT LOCATION DANGER TOP Appliances must not be installed where they may be exposed to a potentially explosive or flammable atmosphere. CAUTION 1. Clearances to combustible materials are critical. Be sure to follow all listed requirements. 2. Heaters are designed for use in heating applications with ambient startup temperatures between -40°F and 90°F, and ambient operating temperatures between 40°F and 90°F. 3.
PAGE 5
UNIT MOUNTING 1. Be sure the means of suspension is adequate to support the weight of the unit (see pages 24-25 for unit weights). 2. For proper operation, the unit must be installed in a level horizontal position. 3. Clearances to combustibles as specified in Table 4.1 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.

INSTALLATION - VENTING A3. All heaters come with factory installed vent and combustion air adapters for attaching the vent pipe to the heater: WARNING Table 6.1 - Vent Pipe Diameters, Transitions, and Total Equivalent Vent Pipe Lengths For Horizontal and Vertical Venting Systems 1. G as fired heating equipment must be vented - do not operate unvented. 2. A built-in power exhauster is provided - additional external power exhausters are not required or permitted. 3.
PAGE 7
INSTALLATION - VENTING 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. A9. 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.

INSTALLATION - VENTING Section B - Vertical 2-Pipe Vent System Installation B1. This section applies to vertically vented 2-pipe (1 combustion air inlet pipe and 1 vent pipe) vent systems and is in addition to “Section A - General Instructions All Units”. B2. Vertical vent systems terminate vertically (up). B3. It is recommended to install a tee with drip leg and clean out cap as shown in Figure 8.1. B4. The combustion air and vent pipes must be terminated with 2 listed vent caps. B5.
PAGE 9
INSTALLATION - VENTING C7. When horizontal vents pass through a combustible wall (up to 22" thick), the vent passage must be constructed and insulated as shown in Figure 9.1. C8. The vent must be supported as shown in Figure 9.1. Figure 9.2 - Vertical Concentric Vent Kit Components Combustion Air Inlet Terminal Figure 9.1 - Exhaust Vent Construction Through Combustible Walls and Support Bracket FIBER GLASS INSULATION MIN. 2" METAL SLEEVE 2" MIN. * Size according to expected snow depth. 12" Min.
PAGE 10
INSTALLATION - VENTING For Vertical Concentric Vent Kits (Refer to Figure 9.2): For Vertical Concentric Vent Kits (Refer to Figure 9.2): • Slide the combustion air cap down over the vent pipe • The bottom of the combustion air intake pipe must terminate above the snow line, or at least 12" above the roof, whichever distance is greater. • The bottom of the vent cap must terminate at least 6" above the top of the combustion air intake cap.

INSTALLATION - GAS CONNECTIONS GAS CONNECTIONS Figure 11.1 - Recommended Sediment Trap/Manual Shut-off Valve Installation - Side or Bottom Gas Connection 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.

INSTALLATION - HIGH ALTITUDE ACCESSORY KIT HIGH ALTITUDE ACCESSORY KIT Manifold Pressure Adjustment 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'.
PAGE 13
INSTALLATION - HIGH ALTITUDE ACCESSORY KIT If the heating value of the gas being supplied is different than the values shown in Tables 12.1 and 12.2, use the following equation to determine the appropriate manifold pressure for the altitude and gas heating value being supplied. Equation 13.1 - Manifold Pressure for Derated Gas WHERE: MPACT = Manifold Pressure (in. W.C.

INSTALLATION - OPERATION OPERATION Prior to Operation IMPORTANT 1. To prevent premature heat exchanger failure, observe heat exchanger tubes. If 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 16 for blower adjustments. 2. Start-up and adjustment procedures must be performed by a qualified service agency.

CONTROL OPERATING SEQUENCE / UNIT COMPONENTS CONTROL OPERATING SEQUENCE Upon a call for heat from the thermostat, power is supplied to the power exhauster motor. The unit will go through a purge period and then the direct spark igniter will be energized. At the same time, the main valve in the combination control valve will open to allow gas to flow to the burners. If the fan motor has not already started it will start shortly.
