SAFETY INFORMATION FOR USERS OF LP-GAS

Propane (LP-Gas)is a flammable gas which can cause fires and explosions. In its natural state, propane is odorless and colorless. You may not know all the following safety precautions which can protect both you and your family from an accident. Read them carefully now, then review them point

bypointwiththemembersofyourhousehold.Somedaywhen theremaynotbeaminutetolose,everyone'ssafetywilldepend 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-GASWARNING 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-Gasis 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 firefighters declare them to be safe.

Use your neighbor's phone and call a trained LP-Gasservice person and the fire department. Even though you may not continue to smell gas, do not turn on the gas again. Do notre-enterthe building, vehicle, trailer, or area.

Finally,lettheservicemanandfirefighterscheckforescaped gas. Have them air out the area before you return. Properly trained LP-Gasservice 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 find 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.

TheodorantinLP-gasiscolorless,anditcanfadeundersomecircumstances.For example, if there is an underground leak, the movement of the gas through soil can filter the odorant. Odorants

in LP-Gasalso are subject to oxidation. This fading can occur if there is rust inside the storage tank or in iron gas pipes.

Theodorantinescapedgascanadsorborabsorbontoorintowalls, 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-Gasmay 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 detectany 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 find 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 qualified, do not light pilot lights, perform service, or make adjustments to appliances on the LP-Gassystem. If you are qualified, consciously think about the odor ofLP-Gasprior to and while lighting pilot lights or performing service or making adjustments.

Sometimes a basement or a closed-uphouse has a musty smell that can cover up theLP-Gasodor. 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 ofLP-Gas.

Odor fade, due to oxidation by rust or adsorption on walls of newcylindersandtanks,ispossible.Therefore,peopleshould 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 filled and allowed to set too

long before refilling. 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.

If, at any time, you do not smell the LP-Gasodorant and you thinkyoushould,assumeyouhavealeak.Thentakethesame immediateactionrecommendedabovefortheoccasionwhen you do detect the odorizedLP-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 orifices. 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 container is under vapor pressure by turning it off at the container before it goes completely empty or having it refilled before it is completely empty.

Water vapor is a by-productof gas combustion. An unvented room heater produces approximately one (1) 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.

This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.

TheNationalFuelGasCode,ANSIZ223.1definesaconfinedspace asaspacewhosevolumeislessthan50cubicfeetper1,000Btuper hour (4.8m3 per kw) of the aggregate input rating of all appliances installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8m3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are installed, through openings not furnished with doors, are considered a part of the unconfined 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 defined 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-strippinghasbeenaddedonopenablewindowsanddoors, and

c.Caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall-ceilingjoints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.

Ifyourhomemeetsallofthethreecriteriaabove,youmustprovide additional fresh air. See “Ventilation Air From Outdoors,” page 8.

Determining if You Have a Confined or Unconfined Space

Usethisworksheettodetermineifyouhaveaconfinedorunconfined space.

Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms.

The following steps will help insure that water vapor does not become a problem.

1.Besuretheheaterissizedproperlyfortheapplication,including ample combustion air and circulation air.

2.If high humidity is experienced, a dehumidifier 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.

1.Determine the volume of the space (length x width x height).

Length x Width x Height = cu. ft. (volume of space)

Example:Spacesize16ft.(length)x10ft.(width)x8ft.(ceiling height) = 1,280 cu. ft. (volume of space)

Ifadditionalventilationtoadjoiningroomissuppliedwithgrills 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.

PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR (continued)

The space in the above example is a confined space because the actualBTU/HrusedismorethanthemaximumBTU/HRthespace can support. You must provide additional fresh air. Your options are as follows:

A.Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grills between rooms. See

Ventilation Air From Inside Building.

B.Vent room directly to the outdoors. See VentilationAir From

Outdoors.

C.Install a lower BTU/Hr heater, if lower BTU/Hr size makes room unconfined.

If the actual BTU/Hr used is less than the maximum BTU/Hr the space can support, the space is an unconfined space.You will need no additional fresh air ventilation.

WARNING: You must provide additional ventilation air in a confined space.

Ventilation Air Ventilation Air From Inside Building (Figure 1)

This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 1). You can also remove door into adjoining room (see option 3, Figure 1). Each ventilation grill or opening shall have a minimum free area of one square inch per 1,000 BTUH of the total input rating of the gas equipment in the confined space.

Note: Never use plastic pipe. Check to confirm whether your local codes allow copper tubing or galvanized.

Note: Since some municipalities have additional local codes, it is always best to consult your local authority and installation code.

Installing a New 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 liquefied 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.

Never use an exposed flame to check for leaks.Appliance must be disconnected from piping at inlet of control valve and pipe capped or plugged for pressure test. Never pressure test with appliance connected; control valve will sustain damage!

A gas valve and ground joint union should be installed in the gas line upstream of the gas control to aid in servicing. It is required by the National Fuel Gas Code that a drip line be installed near the gas inlet. This should consist of a vertical length of pipe tee connected into the gas line that is capped on the bottom in which condensation and foreign particles may collect.

The use of the following gas connectors is recommended:

ANSZ21.24ApplianceConnectorsofCorrugatedMetalTubing and Fittings

ANS Z21.45 Assembled Flexible Appliance Connectors of Other Than All-MetalConstruction

The above connectors may be used if acceptable by the authority havingjurisdictionThestateofMassachusettsrequiresthataflexible appliance connector cannot exceed three feet in length.

VFP(32,36)FP(20,21)LP (Propane gas) will have a manifold pressure approximately 10.0"w.c. (2.49kPa) at the pressure regulator outlet with the inlet pressure to the pressure regulator from a minimum of 11.0"w.c. (2.739kPa) for the purpose of input adjustment to a maximum of 13.0"w.c. (3.237kPa).

Atest gage connection is located downstream of the gas appliance pressure regulator for measuring gas pressure. The connection is a 1/8 inch (3mm) N.P.T. plugged tapping.

VFP(32,36)FP(30,31) Millivolt Control

The valve regulator controls the burner pressure which should be checked at the pressure test point. Turn captured screw counter clockwise 2 or 3 turns and then place tubing to pressure gauge over test point (Use test point “A” closest to control knob).After taking pressure reading, be sure and turn captured screw clockwise firmly to re-seal.Do not over torque. Check for gas leaks.
