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 notre-enterthe building, vehicle, trailer, or area.

Finally,lettheservicemanandfirefighterscheckforescaped 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 are subject to oxidation. This fading can oc-

cur 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.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-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.

Ventilation and Combustion Air

Wall furnaces 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 air for combustion and draft hood dilution.

Where appliances are installed in confined and unconfined spaces 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 and unconfined spaces 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 (6.45cm2) per 2,000 BTU hr. (.6KW/H) of total input.

Qualified Installing Agency

Installation and replacement of gas piping, gas utilization equipment or accessories and repair and servicing of equipment shall be performed only by a qualified agency. The term “qualified agency” means any individual, firm, corporation or company which either in person or through a representative is engaged in and is responsible for (a) the installation or replacement of gas piping or (b) the connection, installation, repair or servicing of equipment, who is experienced in such work, familiar with all precautions required and has complied with all the requirements of the authority having jurisdiction.

State of Massachusetts: The installation must be made by a licensed plumber or gas fitter in the Commonwealth of Massachusetts.

The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54* Natural Gas and Propane Installation Code, CSA B149.1.

Gas Supply

Check all local codes for requirements, especially for the size and type of gas supply line required. On Natural gas lines less than 15’ (4.5m) long, us (1/2” (13mm) pipe; on longer runs, use 3/4” (19mm) iron pipe or equal. On LP gas lines please consult LP gas supplier.

Installing a New Main Gas Cock

Each appliance should have its own manual gas cock.

Amanualmaingascockshouldbelocatedinthevicinityoftheunit.Where none exists, or where its size or locationis not adequate,contactyour 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.

–ANSZ21.45AssembledFlexibleApplianceConnectorsofOtherThanAll-MetalConstructions

The above connectors may be used if acceptable by the authority having jurisdiction.

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 is 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. (1.24kPa). 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).

A1/8”(3mm)N.P.T.pluggedtapping,accessiblefortestgaugeconnection, is located on the outlet side of the gas control.

The built-inregulator comes on at approximately 1/4th pressure and full on in 10 seconds.

High Altitudes

For altitudes/elevations above 2,000 feet (610m), input ratings should be reduced at the rate of 4 percent for each 1,000 feet (305m) above sea level. Canadian High Altitudes for locations having an elevation above mean sea level between 2,000 feet (610m) and 4,500 feet (1370m), the manifold pressure is to be decreased from 4.0” w.c. (.996kPa) to 3.2” (.797kPa) w.c. for Natural Gas and from 10.0” w.c. (2.49kPa) to 8.0” w.c. (1.992kPa) for Propane Gas.

Piezo Pilot Ignitor Instructions

Depressingtheredbuttoncompletelycausesasparktooccuratthepilot.This is a substitute for a match which requires opening the pilot hole cover.

12428-3-0706

Page 6

To light the pilot, it is important that the electrode be 1/8” (3mm) from the thermocouple. The spark must occur at the point the burner flame hits the thermocouple. The end of the electrode will be red hot with the pilot on.

On a new installation with air in the gas line, it is suggested that a match be used. The match will light the pilot faster than the piezo under this condition.

Proper Pilot Flame

The correct pilot flame (Figure 6) will be blue, extending past the thermocouple. The flame will surround the thermocouple just below the tip.

Natural gas pilots require adjusting when the inlet gas pressure is above 5” w.c. (1.245kPa). Remove the pilot cover screw on the control valve (Figure 5), and turn the adjustment screw clockwise to reduce flame. Replace pilot cover screw to eliminate gas leakage.

LP gas (propane) will not require adjustment.

After use, cleaning may be required for the proper flame.

PROPER FLAME ADJUSTMENT

DO MAKE A PERIODIC VISUAL

CHECK OF PILOT & BURNERS

Figure 6

Proper Main Burner Flame

The correct flame will be a short blue inner flame with a much larger light blue outer flame. The main burner (Figure 7) shows the approximate height of each part of the flame for each gas. The burner does not have a primary air adjustment. The flame will be correct if the factory-setpressure and orifice opening are used. After the furnace has been operating, the burner ports may be blocked by foreign matter carried in by combustion air. Therefore, cleaning of the burner may be needed for proper flame.

To clean burner port disconnect the gas supply to the valve, and remove the eight screws fastening the burner door. After removing the burner door from the combustion chamber, remove rear burner, pilot burner and front burner. With front and rear burners removed from furnace, force water into the ribbon ports and dry with air pressure.

If fan motor is replaced, the silicone rubber gaskets, see Page 10, Index No. 5, Part 712059, should also be replaced. The gaskets must be stretched to fit the motor bolts into the gasket holes and then the motor and gaskets installed on the motor mounting bars.

Wiring

The appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes with the National Electrical Code,ANSI/NFPA70 or Canadian Electrical Code CSA C22.1, if an external electrical source is utilized.This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazard and should be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from this plug. For an ungrounded receptacle, an adapter, which has two prongs and a wire for grounding, can be purchased, plugged into the ungrounded receptacle and its wire connected to the receptacle mounting screw. With this wire completing the ground, the appliance cord plug can be plugged into the adapter and be electrically grounded. A 7/8” (22mm) hole is provided in the junction box for use with a conduit connector if local codes require this type of protection.

Thermostat Installation

The thermostat should be installed in the same room as the furnace 4’ (1.2m) to 5’ (1.5m) above the floor and away from another heat source (cooking stove, hot water heater, etc.) including walls and doorways with a heat source in an adjoining room. Do Not Install Thermostat on Outside Wall.

Insulated Vent Enclosure

Vented wall furnaces installed in buildings with flat roofs can have poor venting. The cold vent pipe will have a delay in proper venting and cause the wall furnace to shut “OFF” by the vent safety switch. To prevent delayed venting as well as condensation of flue products an insulated vent enclosure is recommended.

Use type B vent pipe and maintain at least one inch (25mm) clearance to combustibles.

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

1.115 volts to the junction box.

2.Inlet gas pressure.

3.The 24 volt system

4.Type of gas being used and that shown on the rating label.

Servicing the Pilot and Main Burners, Pilot Orifice, Thermocouple, and Main Burner Orifices: Disconnect the gas supply at the inlet to the control valve. Then remove the burner door to which the above components are attached.

Servicing The Fan Motor: The upper front panel the shroud surrounding the fan blade and fan blade must be removed. See “oiling the Motor” paragraph on page 7.

SparkIgniterDoesNotLightPilot:Withairinthegasline,suchaswhen the furnace is first installed or was off all summer, the pilot flame may be too lean to ignite on the first few trials. Turn the control valve knob to pilot position and depress the red reset button. Holding the button down continually to bleed the line;

1.Use lighter rod to light pilot with a match.

2.Use the piezo ignitor at 30 second intervals until it lights.

If Electrode Does Not Produce Spark

1.Check wire connections.

2.Check gap for pilot burner to the electrode tip. Should be between 1/8” (3mm) and 3/16” (5mm). Electrode wire and tip must be more than 1/4” (6mm) away from all other metal components.

If Pilot Does Not Light By Any Means:

1.Check valve knob for being in the “Pilot” position.

2.Check pilot adjustment for being full open (counterclockwise to open).

3.If gas is available in the supply tubing, the pilot orifice and/or pilot burner is probably restricted by a spider web. Clean pilot assembly and relight.

If Pilot Does Not Remain On After Releasing Knob:

1.Follow instructions and hold button down longer and harder.

2.Determine if pilot flame extends past thermocouple; if not, adjust input or clean pilot burner.

3.Replace thermocouple if millivolts read less than 15 millivolts.

Main Gas Valve Does Not Open When Thermostat is Turned To On:

1.Check for 24 volts to valve by removing one wire and touch to the SAME TERMINAL it was on. Terminal should have a light spark.

DO NOT SHORTACROSS TERMINALS,AS ITWILLBURN OUT THE WALLTHERMOSTAT.

2.Thermostat wires at the wall may be shorted, so check for a faulty thermostat.

3.To check for line voltage to furnace, remove lower front panel and switch compartment cover and short across two-terminalfan control to allow fan to operate (Figure 9).

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.
