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

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-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 not reenter the building, vehicle, trailer, or area.

Finally, let the service man and firefighters check for escaped gas. Have them air out the area before you return. Properly trainedLP-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.

The odorant in LP-gasis colorless, and it can fade under some circumstances.For example, if there is an underground leak, the movement of the gas through soil can filter 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-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 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 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 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 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 think you should, assume you have a leak. Then take the same immediate action recommended above for the occasion when 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.

Consult the current National Fuel Gas Code, ANSI Z223.1 CAN/ CGA-B149(.1 or .2) installation code.

Installing a New Main Gas Cock

Each appliance should have its own manual gas cock.

In the state of Massachusetts the gas cock must be a T handle type.

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.

Figure 2

Method of Installing a Tee Fitting Sediment Trap

Pressure Testing of the Gas Supply System

1.To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T. plugged tapping, accessible for test gauge connection, must be placed immediately upstream of the gas supply connection to the appliance.

2.The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

3.The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).

Attention! If one of the above procedures results in pressures in excess of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve, it will result in a hazardous condition.

Checking Manifold Pressure

Both Propane and Natural gas valves have a built-inpressure regulator in the gas valve. Natural gas models will have a manifold pressure of approximately 4.0" w.c. (.996kPa) at the valve outlet with the inlet pressure to the valve from a minimum of 5.0" w.c. (1.245kPa) for the purpose of input adjustment to a maximum of 10.5" w.c. (2.61kPa). 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 11.0" w.c. (2.739kPa) for the purpose of input adjustment to a maximum of 13.0" w.c. (3.237kPa).

A 1/8" (3mm) N.P.T. plugged tapping, accessible for test gauge connection, is located on the outlet side of the gas control.

CLEARANCES

Clearances: When facing the front of the room heater the minimum clearances to combustible construction (material) are the following:

Left side 6 inches (152mm). Right side 6 inches (152mm). Recommend 18 inches ((457mm) on left side for servicing. Do not install in alcove or closet. No horizontal projection above heater permitted within 55 inches (140cm).

Ceiling 55 inches (140cm). Draft hood to rear wall 2 inches (51mm).

Open in front to provide service, access, and clearance to construction.

VENTING

1.Flue pipe must be as large as the flue collar on the draft diverter.

2.Maintain an upward slope of at least 1/4 inch (6mm) per foot of horizontal run.

3.Run flue pipe as directly as possible with a minimum of elbows.

4.Flue pipe should extend through the wall of a chimney to be flush with inner wall.

5.Flue pipe must be adequately supported by metal strips.

6.Single wall vent pipe may be attached directly to the draft hood of the room heater when a clearance of 2 1/2 inches (64mm) is maintained between the single wall vent pipe and the combustible wall of the room in which the room heater is located. Use double wall vent pipe for 1 inch (25mm) clearance to combustibles.

7.For flue pipe running through walls and roof, use B-1[1 inch (25mm) clearance to combustibles] vent pipe.

8.Chimneys should extend at least 2 feet (.6m) above the roof and above any object or nearby building within 10 feet (3m).

9.Open tees should not be used in the flue pipe.

10.Appliance must not be connected to a chimney flue that is servicing a separate solid-fuelburning appliance.

For proper venting, do not attach a 90° elbow directly to draft diverter. If possible, attach 2 feet (.6m) of straight vent pipe before an elbow is used. Use of 45° elbows is recommended.

Uninsulated single-wallmetal pipe shall not be used outdoors in cold climates for venting gas utilization equipment.

Ventilation and Combustion Air

Room heaters shall be installed in a location in which the facilities for ventilation permit satisfactory combustion of gas and proper venting under normal conditions. In buildings of conventional frame, brick or stone construction without tight storm windows and doors, infiltration is normally adequate to provide for combustion and draft hood dilution.

Where appliances are installed in a confined space within a building, the building being of unusually tight construction, air for combustion and ventilation must be obtained directly from outdoors or from such spaces that freely communicate with the outdoors. Under these conditions, the confined space shall be provided with two permanent openings, one near the top of the enclosure and one near the bottom; each opening

shall have a free area of not less than one square inch (6.5cm2) per 1,000 BTU's (.3KW) of total input. The draft hood must be in the same atmospheric pressure zone as the combustion air inlet to the appliance.

Liner and Insulated Liner

When you install a vented room heater into a masonry chimney you must follow these steps.

1.The chimney must be lined and sized properly. Most masonry chimneys are over sized and absorb too much heat to be considered a proper vent. If you have any doubts line the chimney with the right size liner. If it's unlined you must line it.

2.Use an insulated liner when the chimney is on the outside, three sides exposed to the weather, and there is no clay liner in the chimney. The insulation will help keep the flue gases warmer.

Insulated Vent Enclosure

Vented room heaters installed with the vent going directly to the outside and above the eaves can cause poor venting. The cold pipe will have a delay in proper venting and cause the room heater to shut "off" by the vent safety switch. To prevent delayed venting as well as condensation of flue products an insulated enclosure is recommended.

Use type B 5" (127mm) diameter vent pipe and maintain at least a one inch (25mm) clearance to combustibles.

Use metal thimble to protect vent pipe as it passes through combustibles.

VENT SAFETY SHUTOFF SYSTEM

This heater must be properly connected to a venting system. This heater is equipped with a vent safety shutoff system.

Warning:

Operation of this heater, when not connected to a properly installed and maintained venting system or tampering with the vent safety shutoff system, can result in carbon monoxide (CO) poisoning and possible death.

This appliance needs fresh air for safe operation and must be installed so there are provisions for adequate combustion and ventilation air.

This room heater is equipped with a vent safety switch. The vent safety switch will cause gas flow to the pilot to "shut off" due to improper venting or a blocked flue.

If the vent safety switch continues to "shut off" the gas flow to the pilot a qualified service person must be contacted to inspect for improper venting, blockage in the vent pipe or the vent safety switch for being defective.

REVERSIBLE VERTICAL OR HORIZONTAL DRAFT DIVERTER

This room heater has a reversible draft diverter. The draft diverter is installed in the vertical position at the factory. Please use the following steps to change the draft diverter from the vertical position to the horizontal position.

1.Remove L280 vent safety switch from the draft diverter.

2.Inside your yellow instruction envelope will be a 1 1/2" x 2 1/4" (38mm x 51mm) vent safety switch hole cover plate and two (2) 1/2" screws for attachment of vent safety switch hole cover plate to the draft diverter. Attach vent safety switch hole cover plate over hole on the draft diverter from which the L280 vent safety switch was removed.

3.Remove two (2) screws at bottom of draft diverter and lift upward to remove draft diverter from the draft diverter plate. Rotate draft diverter into the horizontal position and slide back into the draft diverter plate. Attach two (2) screws into bottom of the draft diverter.

4.Remove vent safety switch hole knockout and two (2) knockouts for screws on opposite side of draft diverter.

5.Attach L280 vent safety switch to the draft diverter.

6.Repositioning of the draft diverter is completed.

DRAFT DIVERTER CAN BE EITHER A VERTICAL

VENT OR HORIZONTAL VENT

If the pilot will not stay lit after several tries, turn the gas control knob to “OFF” and call your service technician or gas supplier.

10.Attention! Gas control has INTERLOCK latching device. When the pilot is initially lit and the safety magnet is energized (pilot stays on) the INTERLOCK latching device becomes operative. If the gas control is turned to the “OFF” position or gas flow to the appliance is shut off, the pilot cannot be relighted until the safety magnet is deenergized (approximately 60 seconds). There will be an audible “click” when the safety magnet in the gas control is

de-energized.Pilot can now be relighted. Repeat steps 5 through 9.

11.Turn gas control knob counterclockwise to “ON”.

12.Turn on all electric power to the appliance. (If applicable)

13.Replace access panel (front panel). Set thermostat to desired setting.

TO TURN OFF GAS TO APPLIANCE

1.Set thermostat to lowest setting.

2.Turn off all electric power to the appliance. (If applicable) If service is to be performed.

3. Push in gas control knob slightly and turn clockwise t o “OFF". Do not force.

PILOT FLAME CHARACTERISTICS

The correct flame will be almost horizontal, blue and will

extend past the thermocouple 1/4" (6mm). The flame will

3/16" (5mm)

surround the thermocouple just below the tip.

On Propane (LP-gas)slight yellow might occur where the pilot flame and the burner flame meet.

Natural gas pilots require adjusting when the inlet pressure is above 5" w.c. (1.25kPa). Remove pilot adjustment cover. Turn adjustment screw clockwise to reduce flame.

Propane (LP-gas)will not require adjusting.

Figure 5

MAIN BURNER FLAME CHARACTERISTICS

There will be a short blue inner flame with a larger, lighter blue secondary flame. The burner flame may have yellow tips when hot. Dust in the combustion air will produce an orange or red flame. Do not mistake the orange or red flame for an improper yellow flame. The flame will be proper if the factory-setpressure and orifice are used. After use, cleaning may be required for the proper flame.

On Propane gas, if a whistling noise (resonation) occurs

a.Screw the air adjustment bolt into the burner throat to eliminate the whistling noise (resonation).

b.Size main burner orifice with a drill bit. For RH-50(C)use #47 drill bit. ForRH-65(C)use 2.3mm drill bit.

Primary Air Adjustment see page 11.
