INTRODUCTION

Propane gas to be tested enters the ODORATOR through the barbed

tting at the gas supply inlet port. Internally, the gas passes through an internal ve micron lter to the input of a low pressure regulator. It then passes from the output of the low pressure regulator to the ow metering valve. This valve, located on the top panel of the ODORATOR, is operated by the user. After passing through the valve (when opened), the gas enters the mass ow sensor. This is the heart of the ODORATOR. The mass ow sensor responds to gas ow within the range of the ow metering valve.

The signal from the mass ow sensor is then processed, converted to a digital signal and fed to a liquid crystal display (LCD). The gas from the mass ow sensor then passes to the mixing chamber where it is combined with air drawn in by a blower wheel. The user then sniffs the gas / air mixture at the exhaust port. The ow metering valve is incrementally opened and the exhaust port sniffed until odorant is readily detectable at which time the user presses and holds the READ switch down to display percent gas in air by volume.

The electronics and the speed of the blower wheel are calibrated so that the concentration of the propane gas / air sample at the

exhaust port agrees with the LCD at the 25% Lower Explosive Level

(L.E.L.) which is .55% gas. All other readings may be corrected using

the correction chart. The correction chart is included to linearize the instrument within its range. To use the chart, record both the

ODORATOR readily detectable level reading and the corrected actual value. For ODORATOR readings not specied in the chart, linearly

interpolate between the next highest and lowest points on the chart. Do not extrapolate beyond the readings in the chart. Depending on

how much the ow metering valve is opened, the concentration of gas in air at the exhaust port will be anywhere from zero to approximately 1%. The LCD can only indicate up to 1.99%. Concentrations above

1.99% will be indicated by the LCD having its last two digits dashed

out as “1.--”.

When the ODORATOR is turned on, the user might momentarily

notice the letter “L” on the LCD when the READ switch is depressed

and held down. If the “L” fails to disappear, it may be an indication of blower speed. The “L” indicates a speed problem, and if on, the

Odorator should not be used.

When it is time to replace the batteries, “LO BATT” will be indicated in

the upper left corner of the LCD when the READ switch is depressed

and held down.

The ODORATOR is designed and intended to be used in accordance with the GPTC Guide For Gas Transmission And Distribution Piping

Systems, (49 CFR) 192.625 Subpart L dated 10-15-03, the American Society For Testing And Materials Standard D 6273 - 08, and NFPA

58. Supply gas must be propane and of high quality. Blended or mixed gases as sometimes found during peak shaving cannot be

tested using the ODORATOR.

WARNINGS AND CAUTION

PRIOR TO USE, OPERATOR SHOULD READ ALL PRECAUTIONS, INSTRUCTIONS FOR OPERATION, AND MAINTENANCE REQUIREMENTS CONTAINED IN PRODUCT MANUAL.

NOTE: DO NOT USE THE ODORATOR OR BREATHE IN GAS

FROM SOURCES WHICH MAY CONTAIN TOXIC LEVELS OF CHEMICALS, SUCH AS HYDROGEN SULFIDE (H2S), AS IT COULD BE HARMFUL TO HUMAN HEALTH AND SAFETY TO DO SO. SOURCES WHICH MAY CONTAIN TOXIC LEVELS OF CHEMICALS INCLUDE, BUT ARE NOT LIMITED TO, PRODUCTION SYSTEMS AND LANDFILLS.

IT IS THE SOLE RESPONSIBILITY OF THE PRODUCT PURCHASER/ OWNER TO ENSURE THAT: (1) ALL OPERATORS AND/OR USERS OF THE ODORATOR READ, UNDERSTAND, AND COMPLY WITH THE PRECAUTIONS, INSTRUCTIONS FOR OPERATION, AND MAINTENANCE REQUIREMENTS CONTAINED IN THIS MANUAL; (2) THE ODORATOR IS ONLY USED IN A PROPER AND SAFE MANNER; AND (3) WHILE USING THE ODORATOR, OPERATORS ARE NOT INHALING OR SNIFFING DANGEROUS MATERIALS THAT COULD CAUSE INJURY OR DEATH.

HEATH WARRANTS ONLY THAT THE PARTS MANUFACTURED BY IT WILL BE AS SPECIFIED AND FREE OF DEFECTS. HEATH MAKES NO OTHER WARRANTIES OR REPRESENTATIONS OF ANY KIND WHATSOEVER, EXPRESS OR IMPLIED, AND ANY AND ALL IMPLIED WARRANTIES INCLUDING ANY WARRANTY OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE OR USE ARE HEREBY DISCLAIMED.”

DURING OPERATION, KEEP THE ODORATOR AWAY FROM OPEN FLAMES. INLET SUPPLY PRESSURE SHOULD NOT EXCEED FOUR PSIG. INLET PRESSURES IN EXCESS OF FOUR PSIG WOULD RUPTURE THE LOW PRESSURE REGULATOR DIAPHRAGM, VENT THE GAS OUT OF THE INSTRUMENT AND CAUSE AN INSTRUMENT FAILURE. THE RECOMMENDED INLET SUPPLY PRESSURE IS 7” WATER COLUMN.

WHEN OPERATING THE ODORATOR, YOU WILL BE WORKING WITH FLAMMABLE PROPANE GAS WHICH IS POTENTIALLY DANGEROUS IF NOT HANDLED PROPERLY. PROPANE GAS FROM A LECTURE BOTTLE MAY BE ODORLESS AND IS FLAMMABLE IN CONCENTRATIONS OF APPROXIMATELY 2.2 TO 9.6 PERCENT BY VOLUME IN AIR.

WHEN YOU ARE NOT OPERATING THE ODORATOR, CLOSE ALL VALVES AND TURN THE ODORATOR OFF.

iii

ANY TIME GAS IS BEING PASSED THROUGH THE ODORATOR THE POWER SWITCH MUST BE TURNED ON. THIS WILL DILUTE THE GAS AT THE EXHAUST PORT AND PREVENT POCKETS OF CONCENTRATED GAS FROM ACCUMULATING.

100% L.E.L. IS APPROXIMATELY EQUAL TO 2.2% PROPANE GAS BY VOLUME IN AIR. AS LONG AS THE REFERENCE C.G.I. READS SAFELY BELOW THE L.E.L., YOU SHOULD NOT HAVE ANY PROBLEM WITH A FLAMMABLE MIXTURE BUILDING UP.

ANY SUSPICION OF A GAS LEAK BY UNEXPLAINED SOUND OR OPERATION OF THE ODORATOR IS REASON TO IMMEDIATELY SHUT OFF THE GAS SUPPLY VALVES AND THEN SEEK THE CAUSE.

If indoors, do not turn the ODORATOR on until a reference C.G.I. indicates the environment is safe. Likewise, allow the ODORATOR to purge for at least one (1) minute after a reference C.G.I. also indicates the environment is safe. The ODORATOR is NOT DESIGNATED Intrinsically Safe and MUST NOT be used

in a conned space or hazardous location.

WARNING:

KEEP THE ODORATOR AWAY FROM OPEN FLAMES, INLET PRESSURE SHOULD NEVER EXCEED 4 PSIG AND DO NOT OBSTRUCT OR BLOCK THE INTAKE OR EXHAUST PORT.

CAUTION: BECAUSE OF INHERENT LIMITATIONS, LIQUID CRYSTAL

DISPLAYS SHOULD NOT BE SUBJECTED TO EXTREMES OF TEMPERATURE OR HUMIDITY. IF THE INSTRUMENT IS EXPOSED TO A TEMPERATURE BELOW FREEZING OR ABOVE +49 OC (+120 OF), THE LIQUID CRYSTAL DISPLAY MAY TEMPORARILY CEASE TO FUNCTION PROPERLY, AND IN SOME CASES PERMANENT DAMAGE MAY RESULT. IT IS THEREFORE RECOMMENDED THAT THE INSTRUMENT NOT BE SUBJECTED TO EXTREME CONDITIONS SUCH AS A CLOSED VEHICLE IN DIRECT SUNLIGHT OR CONTINUOUS SUB-FREEZING TEMPERATURES.

USE AT ELEVATION: THE ODORATOR SHOULD BE USED WITHIN 1000 FEET OF

ITS CALIBRATION ELEVATION FOR ACCURACY. A READING CORRECTION CHART, FOUND IN APPENDIX C, MAY BE USED FOR ELEVATION CHANGES GREATER THAN 1000 FEET.

Operation

Chapter I

OPERATION:

This Chapter discusses the proper steps to safely operate the ODORATOR.

Also included are procedures for periodic testing and identication of the

ODORATOR’s controls.

Operation of the ODORATOR

WARNING

DURING OPERATION, KEEP THE ODORATOR AWAY FROM OPEN FLAMES. INLET SUPPLY SHOULD NOT EXCEED 4 PSIG AND 1/4 PSIG (7 INCHES WATER COLUMN) IS RECOMMENDED.

See page 7 for pressure reduction accessories.

**NOTE** Connect the ODORATOR to the gas supply with a non-

absorbing, odor-free hose such as high grade urethane, PVC, or Tygon.

**NOTE** Users of the ODORATOR should be selected with

due consideration to smoking habits, colds, and other conditions of health, since these factors affect the sense of smell. It is desirable to select operators with an average sense of smell in order to obtain reasonably consistent results from the use of this instrument.

**NOTE** See Figure 1 on page 4 for reference to the following

steps.

**NOTE** All valves must be closed and the Odorator

turned “OFF”.

A. Odorization Readily Detectable Test Procedure:

1. Prior to attaching the sample hose to the inlet port (1), sniff the sample hose and verify no odorant is detected. If so, replace the sample hose.
