LP-GAS WARNING ODOR
Ifagasleakhappens,youshouldbeabletosmellthegas
becauseoftheodorantputintheLP-Gas.
That'syoursignaltogointoimmediateaction!
• Donotoperateelectricswitches,lightmatches,useyour
phone. Do not do anything that could ignite the gas.
• Geteveryoneoutofthebuilding,vehicle,trailer,orarea.Do
that IMMEDIATELY.
• Closeallgastankorcylindersupplyvalves.
• LP-Gasisheavierthanairandmaysettleinlowareassuchas

outofbasementsandotherlowareas.Stayoutuntilreghters
declarethemtobesafe.
• Useyourneighbor'sphoneandcallatrainedLP-Gasservice
person and the re department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enterthebuilding,vehicle,trailer,orarea.
• Finally,lettheservicemanandreghterscheckforescaped
gas.Havethemairouttheareabeforeyoureturn.Properly
trained LP-Gas service people should repair the leak, then
checkandrelightthegasapplianceforyou.
NO ODOR DETECTED - ODOR FADE
Some people cannot smellwell. Some people cannot smell
theodorofthechemicalputintothegas.Youmustndoutif
youcansmelltheodorantinpropane.Smokingcandecrease
yourabilitytosmell.Beingaroundanodorforatimecanaffectyour
sensitivityorabilitytodetectthatodor.Sometimesotherodorsin
theareamaskthegasodor.Peoplemaynotsmellthegasodoror
theirmindsareonsomethingelse.Thinkingaboutsmellingagas
odorcanmakeiteasiertosmell.
TheodorantinLP-gasiscolorless,anditcanfadeundersome
circumstances.Forexample,ifthereisanundergroundleak,the
movementofthegasthroughsoilcanltertheodorant.Odorantsin
LP-Gasalsoaresubjecttooxidation.Thisfadingcanoccurifthere

Theodorantinescapedgascanadsorborabsorbontoorintowalls,
masonryandothermaterialsandfabricsinaroom.
That will take some of the odorant out of the gas, reducing its
odor intensity. LP-Gas may stratify in a closed area, and the odor
intensity could vary at different levels. Since it is heavier than air,
theremaybemoreodoratlowerlevels.Alwaysbesensitivetothe
slightestgasodor.Ifyoudetectanyodor,treatitasaseriousleak.
Immediately go into action as instructed earlier.
SOME POINTS TO REMEMBER
• LearntorecognizetheodorofLP-gas.Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it to
ndoutwhatthepropaneodorsmellslike.Ifyoususpectthat
yourLP-Gashasaweakorabnormalodor,callyourLP-Gas
Dealer.
• Ifyouarenotqualied,donotlightpilotlights,performservice,
ormakeadjustmentstoappliancesontheLP-Gassystem.If
youarequalied,consciouslythinkabouttheodorofLP-Gas
prior to and while lighting pilot lights or performing service or
makingadjustments.
• Sometimes a basement or aclosed-uphouse has a musty
smell that can cover up the LP-Gas odor. Do not try to light
pilotlights,performservice,ormakeadjustmentsinanarea
where the conditions are such that you may not detect the odor
iftherehasbeenaleakofLP-Gas.
• Odorfade,duetooxidationbyrustoradsorptiononwallsof
newcylindersandtanks,ispossible.Therefore,peopleshould
beparticularlyalertandcarefulwhennewtanksorcylinders
areplacedinservice.Odorfadecanoccurinnewtanks,or
reinstalledoldtanks,iftheyarelledandallowedtosettoo
longbeforerelling.Cylindersandtankswhichhavebeenout
of service for a time may develop internal rust which will cause
odor fade. If such conditions are suspected to exist, a periodic
snifftestofthegasisadvisable.If you have any question
about the gas odor, call your LP-gas dealer. A periodic
sniff test of the LP-gasisagoodsafetymeasureunder
any condition.

Watervaporisaby-productofgascombustion.Anunventedroom
heater produces approximately one ounce (30ml) of water for every
1,000BTU's(.3KW's)ofgasinputperhour.
Unvented room heaters are recommended as supplemental heat (a
room) rather than a primary heat source (an entire house). In most
supplemental heat applications, the water vapor does not create a
problem.Inmostapplications,thewatervaporenhancesthelow
humidity atmosphere experienced during cold weather.
The following steps will help insure that water vapor does not
becomeaproblem.
1. Be sure the heater is sized properly for the application, including
amplecombustionairandcirculationair.
2. Ifhighhumidityisexperienced,adehumidiermaybeusedto
help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat
source.
Thisheatershallnotbeinstalledinaconnedspaceorunusually
tight construction unless provisions are provided for adequate
combustionandventilationair.

roomsareconnedspaces.Furnacesinstalledinaconnedspace
which supply heated air to areas outside the space must draw return
air from outside the space through tightly sealed return air ducts. A
connedspacemusthave2openingsintothespaceforcombustion
air.Oneopeningmustbewithin12inchesoftheceilingandthe
othermustbewithin12inchesoftheoor.Therequiredsizingof
theseopeningsisdeterminedbywhetherinsideoroutsideairis
usedtosupportcombustion,themethodbywhichtheairisbrought
tothespace(verticalorhorizontalduct)andbythetotalinputrate
of all appliances in the space.
Unusually Tight Construction
Theairthatleaksarounddoorsandwindowsmayprovideenough
freshairforcombustionandventilation.However,inbuildingsof
unusually tight construction, you must provide additional fresh air.
Unusually tight construction is dened as construction
where:
a. Walls and ceilings exposed to the outside atmosphere have
a continuous water vapor retarder with a rating of one perm
orlesswithopeningsgasketedorsealed,and
b. Weather-stripping has beenadded on openable windows
and doors, and
c. Caulking or sealants are applied to areas such as joints

oors,betweenwall-ceilingjoints,betweenwallpanels,at
penetrationsforplumbing,electrical,andgaslines,andat
other openings.
Ifyourhomemeetsallofthethreecriteriaabove,youmustprovide
additional fresh air. See “VentilationAirFromOutdoors,” page
14.
DeterminingifYouHaveaConnedorUnconnedSpace
Usethisworksheettodetermineifyouhaveaconnedorunconned
space.
Space: Includes the room in which you will install heater plus any
adjoining rooms with doorless passageways or ventilation grills
betweentherooms.
1. Determine the volume of the space (length x width x height).
Length x Width x Height = cu. ft. (volume of
space)
Example: Space size 16 ft. (length) x 10 ft. (width) x 8 ft. (ceiling
height) = 1,280 cu. ft. (volume of space)
If additional ventilation to adjoining room is supplied with grills
or openings, add the volume of these rooms to the total volume
of the space.
2. Divide thespacevolume by 50 cubic feet to determine the
maximum BTU/Hr the space can support.
(volume of space) ÷ 50 cu. ft. = (maximum
BTU/Hr the space can support)
Example: 1,280 cu. ft. (volume of space) ÷ 50 cu. ft. = 25.6 or
25,600 (maximum BTU/Hr the space can support)
3. AddtheBTU/Hrofallfuelburningappliancesinthespace.

Example: Vented gas heater 20,000 BTU/Hr

Total = 38,000 BTU/Hr
*Donotincludedirect-ventgasappliances.Directventdraws

4. Compare the maximum BTU/Hr the space can support with the
actual amount of BTU/Hr used.
BTU/Hr (maximum the space can support)
BTU/Hr (actual amount of BTU/Hr used)
Example:
25,600 BTU/Hr (maximum the space can support)

IMPORTANT: Do not provide openings for inlet or outlet air into attic
if attic has a thermostat-controlled power vent. Heated air entering
the attic will activate the power vent.
