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-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 firefighters declare them to be safe.

• Use your neighbor's phone and call a trained LP-Gas service person and the fire 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 firefighters 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 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-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 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-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 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-Gas system. If you are qualified, consciously think about the odor of LP-Gas prior to and while lighting pilot lights or performing service or making adjustments.

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-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.

• 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 filled and allowed

• 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.

N.Y. 10036.

High Altitudes

For altitudes/elevations above 2,000 feet, input ratings should be reduced at the rate of 4 percent for each 1,000 feet 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. to 3.2" w.c. for Natural Gas and from 10.0" w.c. to 8.0" w.c. for Propane Gas.

Piezo Pilot Ignitor Instructions

Depressing the red button completely causes a spark to occur at the pilot. this is a substitute for a match which requires opening the pilot hole cover.

to light the pilot, it is important that the electrode be 1/8" 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.

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.

Page 7

Figure 3

Checking Manifold Pressure

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 4.0" w.c. at the valve outlet with the inlet pressure to the valve from a minimum of 6.0" w.c. for the purpose of input adjustment to a maximum of 7.0" w.c. Propane gas models will have a manifold pressure approximately 10.0" w.c. at the valve outlet with the inlet pressure to the valve from a minimum of 11.0" w.c. for the purpose of input adjustment to a maximum of 13.0" w.c. a 1/8" N.P.t. plugged tapping, accessible for test gauge connection, is located on the outlet side of the gas control.

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

CLEARANCES

Clearances

1. In selecting a location for installation, it is necessary to provide adequate accessibility clearances for servicing and proper installation.

Installing a Vent Near a Window Ledge,

Other Type of Projection or on Siding (vinyl, aluminum, etc.)

Direct vent furnaces are designed to be installed on a uniform outside wall. When the wind comes from any angle (up, down or from either side), it must hit the vent cap equally over both the air inlet and the flue outlet portions of the vent. Any wall projection, such as a door or window casing, which disturbs the wind on one side of the air inlet section will result in back pressure on the flue section smothering the flame and eventual pilot outage.

When the vent cap is to be installed on siding or it appears that a projection within 6" of any side of the air inlet section could shield the air inlet section, the entire vent should be supported away from the wall at least the distance of the projection. 2" x 4" framing whose outside dimensions match the overall dimensions of the mounting plate is recommended. the 2" x 4" framing protects siding from possible warpage or discoloration. all joints can then be sealed and painted. the wall depth plus the additional depth of the 2" x 4" framing should not exceed a total depth of 19" for

DV-55T. (See Figure 10)

Vinyl siding vent kit, DV-822, is available from empire Comfort

Systems, Inc. the depth is 3", which enables the vent cap to be extended away from siding or projections. the wall depth plus the additional 3" depth of the vinyl siding vent cap extension should not exceed a total depth of 19" for DV-55T. (See Figure 11)

Warning: When vinyl siding vent kit, DV-822 or 2" x 4" framing is added to an existing installation (furnace is installed) do not attempt to add sections of pipe to the flue outlet tube or air inlet tube. An air tight seal is required for both tubes. Refer to Parts List, page 16 to order tubes.

PILOT FLAME CHARACTERISTICS

The correct pilot flame (Figure 12) 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. Remove the pilot cover screw on the control valve

(Figure 3, page 8), and turn the adjustment screw clockwise to reduce flame. Replace pilot cover screw to eliminate gas leaking at that control valve opening.

LP gas (propane) will not require adjustment.

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

PROPeR FLaMe aDJUStMeNt

Figure 12

MAIN BURNER FLAME CHARACTERISTICS

The correct flame will be a short blue inner flame with a much larger light blue outer flame. The main burner (Figure 13) 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-set pressure 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.

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/NFPA 70 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 " 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' to 5' 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.

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

SERVICE & MAINTENANCE SUGGESTIONS

Replacing Fan and Oiling the Motor the fan motor should be cleaned and oiled once each heating season. to reach the motor, withdraw the metal shroud surrounding the fan blade by removing the screws on each side. Oil holes are located on the top at each end of the motor. Use a few drops of #10 motor oil. to clean the motor, blow air through its ventilation openings with a vacuum cleaner or low pressure air source.

If fan motor is replaced, the silicone rubber gaskets, see Page 16,

Index No. 4, Part No. 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.

GENERAL : All furnaces have been fire-tested to check for proper operation. This includes, main burner flame, pilot flame, fan operation, fan control, limit control and automatic valve operation.

If the furnace fails to function on initial installation, it is advisable to re-check the following:

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.

the Service Department at empire Comfort Systems, Inc. may be contacted to assist in servicing furnace or call a qualified serviceman..

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

"Replacing Fan and Oiling the Motor" paragraph above.

Spark Igniter Does Not Light Pilot: With air in the gas line, such as when 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" and 3/16". electrode wire and tip must be more than 1/4" 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.

Pilot Outage During Normal Operation:

1. Check air inlet tube for a good tight fit at both ends (6" diameter tube).

2. Check burner door and pilot hole cover for tight seal.

3. Check input by manifold pressure gauge or gas meter.

Main Gas Valve Does Not Open When Thermostat Is Turned

To On:

1. Check for 24 volts to valve by removing one wire and touching to the SAME TERMINAL it was on. terminal should have a light spark. DO NOT SHORT ACROSS

TERMINALS, AS IT WILL BURN OUT THE WALL

THERMOSTAT.

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 twoterminal fan control to allow fan to operate. (Figure 14)
