WARNING
When used without adequate combustion and ventilation air, the heater may give off CARBON MONOXIDE, an odorless, poisonous gas.

Do not install the heater until all necessary provisions are made for combustion and ventilation air. Consult the written instructions provided with the heater for infor-mation concerning combustion and ventilation air. In the absence of instructions, refer to the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation, or applicable local codes.  This heater is equipped with a PILOT LIGHT SAFETY SYSTEM designed to turn off the heater if not enough fresh air is available.

DO NOT TAMPER WITH THE PILOT LIGHT SAFETY SYSTEM!

  • If the heater shuts off, do not relight until you have fresh air.
  • If the heater keeps shutting off, have it serviced? Keep the burner and control compartment clean.

Carbon monoxide poisoning may lead to death.

  • Early signs of carbon monoxide poisoning resemble the flu, with headache, dizziness, and/or nausea. If you have these signs, the heater may not be working properly. Get fresh air at once! Have heater serviced.
  • Some people — pregnant women, persons with heart or lung disease, anemia, those under the influence of alcohol, and those at high altitudes — are more affected by carbon monoxide than others.
  • The pilot light safety system senses the depletion of oxygen at its location. If this heater is installed in a structure having a high vertical dimension, the possibility exists that the oxygen supply at the higher levels will be less than that at the heater. In this type of application, a fan to circulate the structure air will minimize this effect. The use of this fan will also improve the comfort level of the structure. When a fan is used to circulate air, it should be located so that the airflow is not directed at the burner.

SAFETY INFORMATION FOR USERS OF LP-GAS
Propane (LP-Gas) is a flammable gas that can cause fires and explosions. In its natural state, propane is odorless and colorless. You may not know all the following safety precautions that 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, or 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 servicemen 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, and 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 the 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 before and while lighting pilot lights 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 filled and allowed to set too long before refilling. Cylinders and tanks that 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 questions 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 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 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 empty or having it refilled before it is empty.

  • The floor stand can not be used in a bathroom or bedroom installation. SR-6 must be wall mounted in a bathroom or bedroom installa-tion.
  • The floor stand can not be used in a bedroom installation. SR-10 must be wall-mounted in a bedroom installation.

The bathroom or bedroom must be an unconfined space. ANSI Z223.1/NFPA54 defines 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.”

WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An unvented room heater produces approximately one (1) ounce (30ml) of water for every 1,000 BTUs (.3KW’s) of gas input per hour. Unvented room heaters must be used 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.

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

  1. Be sure the heater is sized properly for the application, 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 (an entire house).

PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR

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

A confined space is an area with a volume of less than 50 cubic feet per 1,000 Btuh of the combined input rates of all appliances drawing combustion air from that space. Small areas such as equipment rooms are confined spaces. Furnaces installed in a confined space that supply heated air to areas outside the space must draw return air from outside the space through tightly sealed return air ducts. A confined space must have 2 openings into the space for combustion air. One opening must be within 12 inches of the ceiling and the other must be within 12 inches of the floor. The required sizing of these openings is determined by whether inside or outside air is used to support combustion, the method by which the air is brought to the space (vertical or horizontal duct), and the total input rate of all appliances in the space.

The following example is for determining the volume of a typical area in which the SR-18 may be located and for determining if this area fits the definition of an unconfined space. The maximum input of the SR-18 is 18,000 Btu per hour. Based on the 50 cubic feet per 1,000 Btu per hour formula, the minimum area that is an unconfined space for installation of the SR-18 is 900 cubic feet, 50 cubic feet x 18 = 900 cubic feet. To determine the cubic feet of the area in which the SR-18 is to be installed, mea-sure the length, width, and height of the area. Example: The area measures 13 feet in length, 9 feet in width, and 8 feet in height, the area is 936 cubic feet. The SR-18 can be installed in this confined space with no requirement to provide additional combustion and ventilation air.

WARNING
If the area in which the heater may be operated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation, or applicable local codes.

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:

  • 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
  • Weatherstripping has been added on openable windows and doors, and
  • Caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and other openings.

If the heater is installed in a building of unusually tight construction, adequate air for combustion, ventilation and dilution of flue gases shall be provided per ANSI Z223.1/NFPA54.

GAS SUPPLY

The gas line can be routed either through the floor or wall. The gas line opening should be made at this time. The location of the opening will be determined by the position of the floor joists and the valve and union used for servicing.

Gas Supply
Check all local codes for requirements, especially for the size and type of gas supply line required.

  • NOTICE: Never use plastic pipe. Check to confirm whether your local codes allow copper tubing or galvanized.
  • NOTICE: 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 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. The appliance must be disconnected from the piping at the inlet of the control valve and the pipe capped or plugged for a pressure test. Never pressure test with the appliance connected; the 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 to the gas line that is capped on the bottom in which condensation and foreign particles may collect.

Method of Installing a Tee-Fitting Sediment Trap (Figure 2)
The use of the following gas connectors is recommended:

  • ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing and Fittings
  • ANS Z21.45 Assembled Flexible Appliance Connectors of Other Than All-Metal Construction

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 its appliance main gas valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures over 1/2 psig (3.5 kPa).
  3. The appliance must be isolated from the gas supply piping sys-tem by closing its equipment 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 over 1/2 psig (14″ w.c.) (3.5 kPa) on the appliance gas valve, it will result in a hazardous condition.

Checking Manifold Pressure
Natural gas will have a manifold pressure of approximately 6.0″ w.c. (1.49kPa) at the pressure regulator outlet with the inlet pressure to the pressure regulator from a minimum of 7.0″ w.c. (1.743kPa) for input adjustment to a maximum of 10.5″ w.c. (2.615kPa). Propane/LP gas will have a manifold pressure of 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 input adjustment to a maximum of 13.0″ w.c. (3.237kPa).

A test gauge 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.

LIGHTING INSTRUCTIONS

FOR YOUR SAFETY READ BEFORE LIGHTING

WARNING:
If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury, or loss of life.

  • This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly.

  • BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
    WHAT TO DO IF YOU SMELL GAS

    • Do not try to light any appliance.
    • Do not touch any electrical switch;
    • Do not use any phone in your building.
    • Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.
    • If you cannot reach your gas supplier, call the fire department.
  • Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, don’t try to repair it; call a qualified service technician. Force or attempted repair may result in a fire or explosion.

  • Do not use this appliance if any part has been underwater. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control that has been under water.

  2. Push in the manual gas control knob slightly and turn clockwise to “OFF”. Do not force.

CHARACTERISTICS

MAIN BURNER FLAME CHARACTERISTICS

SR-6 Main Burner Flame (Figure 15)
The main burner flame will have a red-orange glow over the surface of the ceramic plaque. The red-orange glow on the surface of the ceramic plaque will have a pattern in the shape of a number 1. The perimeter of the ceramic plaque [approximately the outside 1/4″(6mm)] will not glow. A few small, hairline cracks may form over the surface of the ceramic plaques or at the edges of the ceramic plaques where they have been cemented into position on the burner assembly frame. These small, hairline cracks will not affect the operation or performance of the ceramic plaques. Only, when large cracks develop, with blue flames escaping from the large cracks, should you contact your QUALIFIED SERVICE PERSON.

SR-10, SR-18, and SR-30 Main Burner Flame (Figure 16)
The main burner flame will have a red-orange glow over the surface of the ceramic plaques. A few small, hairline cracks may form over the surface of the ceramic plaques or at the edges of the ceramic plaques where they have been cemented into position on the burner assembly frame. These small, hairline cracks will not affect the operation or performance of the ceramic plaques. Only, when large cracks develop, with blue flames escaping from the large cracks, should you contact your QUALIFIED SERVICE PERSON.

A red-orange haze that is visible on the ceramic plaques is acceptable. A blue flame that rolls out at the top of the ceramic plaques indicates an accumulation of dust, lint, or spider webs inside the casing assembly and main burner assembly. Use the following procedure to inspect the casing assembly and main burner as-sembly.

  1. Turn OFF the gas supply to the heater.
  2. Turn OFF the electric supply to the heater if an optional blower is installed in the heater.
  3. Remove the lower louver from the casing assembly ( 2 screws).
  4. Remove the reflector from the casing assembly (2 screws).
  5. Inspect the interior of the casing assembly for accumulation of dust, lint, or spider webs. If necessary, clean the interior of the casing assembly with a vacuum cleaner or apply air pressure. Do not damage any components within the casing assembly when you are cleaning.
  6. Remove the pilot bracket from the main burner assembly (2 screws).
  7. Pivot pilot bracket with attached pilot away from main burner assembly (do not damage pilot tubing).
  8. Inspect the main burner orifice(s) through the rectangular opening(s) in the venturi (throat) of the main burner(s). Dust, lint, and spider webs can accumulate on top of the main burner orifice(s). If necessary, clean the main burner orifice(s) with a vacuum cleaner or apply air pressure. To thoroughly clean the main burner orifice(s) proceed to Step 9.
  9. Disconnect supply tubing from orifice holder(s).
  10. Remove the orifice holder from the venturi of the main burner assembly (1 screw for each orifice holder).
  11. Remove main burner orifice from the orifice holder.
  12. Apply air pressure through the main burner orifice and orifice holder to remove dust, lint, or spider webs.
  13. Apply air pressure into ceramic plaque(s) to remove dust, lint, or spider webs.
  14. As parts are being replaced in reverse order, check for gas leaks at all gas connections before the lower louver is replaced onto the casing assembly.

PILOT FLAME CHARACTERISTICS
The correct flame will be blue and will extend beyond the thermocouple. The flame will surround the thermocouple just below the tip. A slight yellow flame may occur where the pilot flame and main burner flame meet.

When the pilot has a large yellow tip flame, clean the Oxygen Depletion Sensor as follows:

  1. Clean the ODS pilot by loosening nut B from the pilot tubing. When this procedure is required, grasp nut A with an open-end wrench.
  2. Blow air pressure through the holes indicated by the arrows. This will blow our foreign materials such as dust, lint, and spider webs. Tighten nut B also by grasping nut A.

WARNING
Never use needles, wires, or similar cylindrical objects to clean the pilot to avoid damaging the calibrated ruby that controls the gas flow.

MAIN BURNER OPERATION

Piezo Pilot Ignitor Instructions

  • Depressing the ignitor button completely causes a spark to occur at the pilot.
  • To light the pilot, the electrode must be 1/8″ (3mm) from the pilot. The spark must occur at the point the pilot flame hits the thermocouple.
  • 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.

TROUBLESHOOTING

  1. The spark electrode does not produce a spark.

  2. The spark electrode is broken – replace.

  3. Ignitor wire may not be attached to spark electrode -attach.

  4. Ignitor wire damaged – replace.

  5. Piezo ignitor defective – replace.

  6. The spark electrode produces a spark but the pilot does not light.

    • No gas to heater – turn on the gas.
    • PILOT position not properly aligned – turn the gas control knob to PILOT position and depress.
    • The pilot is blocked from a spider web or a dirt-clean pilot.
  7. The pilot flame does not stay “on” when the control knob is released.

    • The control knob in the PILOT position is not completely depressed or held in long enough.
    • The thermocouple is not tightened into gas control – tighten the thermocouple.
    • Pilot flame not surrounding thermocouple – clean pilot.
    • Inlet gas pressure is too low, contact the gas supplier.
    • Thermocouple defective – replace.
    • Gas control defective – replace.
  8. The main burner does not ignite.

    • The main burner orifice is blocked – clean, see “Main Burner Flame Characteristics.
      Attention: The number stamped on the main burner orifice is a millimeter in diameter.

    • Inlet gas pressure is too low, contact the gas supplier.

  9. The heater keeps shutting “OFF” during normal operation.

    • The pilot is blocked – clean pilot.
    • Inlet gas pressure is too low, contact the gas supplier

Excessive Blower Wheel Noise

ATTENTION!
If your blower assembly develops a squeal, hum, or grinding noise, it indicates dirt or debris on the shaft of the blower wheel. Use the following steps to clean the shaft of the blower wheel.

  2. Clean the blower wheel shaft with a cotton cloth.

  3. Place 1 or 2 drops of all-purpose oil on the END of the blower wheel shaft.

  4. Replace the red rubber grommet with brass bushing or the black rubber grommet with brass bushing onto the end of the blower wheel shaft.
    Attention: The red rubber grommet with brass bushing or the black rubber grommet with brass bushing must “snap back” into position.

  5. Cleaning of the blower wheel shaft is completed.

Wiring
The appliance, when installed, must be electrically grounded by local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, if an external electrical source is utilized. This appliance is equipped with a three-prong [grounding] plug for your protec-tion against shock hazards 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.

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

Blower Motor
The blower motor does not have oiling holes. Do not attempt to oil the blower motor.

Blower Wheel
The blower wheel will collect lint and could require periodic cleaning. If the air output decreases or the noise level increases, it indicates a dirty blower wheel.

To clean the blower wheel:

  1. Turn OFF the gas supply to the heater.
  2. Turn OFF the electrical supply to the heater.
  3. Remove the lower louver from the casing assembly (2 screws).
  4. Remove the reflector from the casing assembly (2 screws).
  5. Remove the upper louver from the casing assembly (2 screws).
  6. Clean the blower wheel with a vacuum cleaner.
  7. As parts are being replaced in reverse order, check for gas leaks at all gas connections before the lower louver is replaced onto the casing assembly.

WARNING
Unplugging of blower accessory will not stop the heater from cycling. To turn off the gas to the unvented heater: Push in the gas control knob slightly and turn clockwise to “OFF.” Do not force.

If any of the original wires as supplied with the appliance must be replaced, it must be replaced with type 125°C wire or its equivalent.
