SAFETY INFORMATION FOR USERS OF LP-GAS

and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precau-
tions which can protect both you and your family from an ac-
cident. Read them carefully now, then review them point by
point with the members of your household. Someday when
there may not be a minute to lose, everyone’s safety will depend
on knowing exactly what to do. If, after reading the following
information, you feel you still need more information, please
contact your gas supplier.
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 basements. When you have reason to suspect a gas leak,
keep 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

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
is rust inside the storage tank or in iron gas pipes.
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. Aperiodic
sniff test of the LP-gas is a good safety measure under
any condition.
• If,atanytime,youdonotsmelltheLP-Gasodorantandyou
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
• Ifyouexperienceacomplete“gasout,”(thecontainerisunder
no vapor pressure), turn the tank valve off immediately. If the
container valve is left on, the container may draw in some air
throughopeningssuchaspilotlightorices.Ifthisoccurs,some
new internal rusting could occur. If the valve is left open, then
treat the container as a new tank. Always be sure your con-
tainer is under vapor pressure by turning it off at the container

Installing the Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of the unit.
Wherenoneexists,orwhereitssizeorlocationisnotadequate,
contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant
totheactionofliqueedpetroleumgases.Thegaslinesmustbe
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.

Theapplianceandit’sindividualshutoffvalvemustbedisconnected
from supply piping system during any pressure testing of that system
at test pressures in excess of 1/2 psig (3.5kPa).
The appliance must be isolated from the gas supply piping system
by closing its individual manual shut off valve during any pressure
testingofthegassupplypipingsystemattestpressuresequalto
or less than 1/2 psig (3.5kPa).
Attention! If one of the procedures results in pressures in excess of

in a hazardous condition.
Checking Manifold Pressures
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a manifold
pressure of approximately 3.5” w.c. (.871kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 4.5” w.c.
(1.120kPa) for the purpose of input adjustment to a maximum of
14.0” w.c. (3.484kPa). Propane gas models will have a manifold
pressure approximately 10.0” w.c. (2.49kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 10.8” w.c.
(2.68kPa) for the purpose of input adjustment to a maximum of
14.0” w.c. (3.484kPa).

pull forward on the vent slide plate assembly. Do not use excessive
force on the vent slide plate. Once the vent slide plate is close
to seating, install the bolt (provided in the installation envelope)
throughthecenterholeoftheinserttopange,andintothevent
slide plate nut. Using a wrench, tighten the bolt until the vent slide
plate is seated forward completely.
Positioning, Leveling, and Securing Insert
1. Place the insert into position.
2. Level the insert from side to side and front to back.
3. If necessary, use the leveling bolts included in the instruction
pack. Screw the legs into the nuts installed in the bottom of
the insert. Turn legs in until insert is level.
NOTICE: If desired, it is acceptable to attach metal strapping
orbrackets(notprovided)fromthereplacecavitytotheinsert

Vertical Through the Roof Applications
The Gas Fireplace Insert has been approved for:
a) Vertical installations up to 40 feet in height (top of insert to cap).
b) Ensure that existing vent run has no more than two sets of 45
degree elbow offsets within the vertical installation. From 0 to a
maximum of 8 ft. of vent pipe can be used between elbows.
c) Ensure that the existing vent run is support as follows: Wall
straps must be used to support offset pipe every 4'.
Thisapplicationwillrequirethatyourstdeterminetheroofpitch
and use the appropriate venting components.
General Maintenance
Conduct an inspection of the venting system semi-annually.
Recommended areas to inspect are as follows:
1. Check areas of the venting system which are exposed to the
elements for corrosion. These will appear as rust spots or
streaks and, in extreme cases, holes. These components should
immediately be replaced.
2. Removethecapandshineaashlightdownthevent.Remove
any bird nests or other foreign material.
3. Check for evidence of excessive condensate, such as water
dropletsformingintheexventingandsubsequentlydripping
out at joints or seams. Condensate can cause corrosion of caps,
pipeandttings.Itmaybecausedbyhavingexcessivelateral
runs, or having exterior portions of the system exposed to cold
weather.
4. Inspectjointstoverifythatnopipesectionsorttingshavebeen
disturbedand,consequently,loosened.Also,checkmechanical
supports,suchaswallstrapsormetalplumbers’tapeforrigidity.
Determining Minimum Vent Height Above the Roof.

ROOF PITCH H (Min.)
Flat to 6/12 12" (305 mm)
6/12 to 7/12 15" (381 mm)
Over 7/12 to 8/12 18" (457 mm)
Over 8/12 to 16/12 24" (610 mm)
Over 16/12 to 21/12 36" (914 mm)
Figure 10
NOTICE: For steep roof pitches, the vent height must be increased.
In high wind conditions, nearby trees, adjoining roof lines, steep
pitched roofs, and other similar factors can result in poor draft, or
down-drafting. In these cases, increasing the vent height may solve
this problem.

When terminating the vent cap near an exterior wall or overhang,
maintain minimum clearances as shown in Figure 11.
