ASSEMBLY AND HOOK-UP INFORMATION

1. Heater model MHS15T and MHS30T are packaged completely. Propane cylinders (tanks) are not included with heater model.
2. Remove heater from carton.
3. use only vapor withdrawal lP gas cylinders constructed for use with propane only (HD-5) and marked in accordance with the specifications for lP gas cylinders of the U.S. Department of Transportation (DOT SPEC. 39).
4. this heater must be used only with a vapor withdrawal LP gas bulk tank equipped with a standard POL valve – do not use this heater on bulk tanks greater than 20 pounds LPG capacity (50 pounds water capacity).

5a. MHS30T dual Burner Model (see Figure 1.)

• Assembly of the MHS30T requires a Phillps screw- driver.
• The tank collar bracket must be assembled before the heater can be attached to the propane tank.
• Remove screws holding tip switch bracket to manifold center plate and retain for later use.
• Align bolt holes in tank collar bracket with bolt holes in center plate on manifold such that the heater is facing outward once attached to cylinder collar.
• Attached with screws removed above, making sure that tip switch bracket is between tank collar bracket and manifold center plate.
• Place heater onto tank with tank collar bracket over tank collar. Mounting bolt knob should be positioned to the outside of tank collar.
• Firmly secure to tank by hand-tightening mounting bolt knob. Do not overtighten.
• Make sure heater regulator is in the “OFF” position.
• Insert regulator’s connector into tank’s valve and turn left (counterclock-wise) with hand as much as possible. Do not overtighten.

5b. MHS5T single Burner Model (see Figure 2.)

• Be sure heater is facing away from tank.
• Insert regulator connector into tank valve outlet fitting and turn left (counterclock-wise) until fully tightened. Do not overtighten. (See Figure 2a)
• Place heater support around venturi and slide clip ends onto propane cylinder collar. Use 1/4”-20 x

|
---|---

35mm screw and wing nut to secure heater support onto venturi tube. (See Figure 2b)
6. operate only on a stable, level surface.
7. Open propane tank valve slowly.
8. Check all fittings for leaks. Apply a 50/50 mixture of liquid soap and water to all joints. Bubbles forming indicate a leaking connection. Correct all leaks before proceeding.
Warning
**** Never touch heater while in operation to avoid injury.
Move heater by grasping the propane cylinder carefully.
9. the heater should be inspected before each use and at least annually by a qualified service person.
10. the hose assembly shall be visually inspected prior to use of heater. If it is evident there is excessive abrasion or wear, or the hose is cut, it must be replaced prior to the heater being put into operation. Replacement hose assembly shall be ReDStone hose assembly as listed in the parts list.
11. Minimum inlet gas pressure is 20 psi.
12. Maximum inlet gas pressure is 120 psi (equivalent to an ambient temperature of 75°F (24°C)).

ODOR FADE WARNING

WARNING
Asphyxiation Hazard

• Do not use this heater for heating human living quarters.
• Do not use in unventilated areas.
• The flow of combustion and ventilation air must not be obstructed.
• Proper ventilation air must be provided to support the combustion air requirements of the heater being used.
• Refer to the specification section of the heater’s manual, heater dataplate, or contact the factory to determine combustion air ventilation requirements of the heater.
• Lack of proper ventilation air will lead to improper combustion.
• Improper combustion can lead to carbon monoxide poisoning leading to serious injury or death. Symptom of carbon monoxide poisoning can include headaches, dizziness and difficulty in breathing.

FUEL GAS ODOR
LP gas and natural gas have man-made odorants added specifically for detection of fuel gas leaks.If a gas leak occurs you should be able to smell the fuel gas. Since Propane (LP) is heavier than air you should smell for the gas odor low to the floor.
ANY GAS ODOR IS YOUR SIGNAL TO GO INTO IMMEDIATE ACTION!

• Do not take any action that could ignite the fuel gas. Do not operate any electrical switches. Do not pull any power supply or extension cords. Do not light matches or any other source of flame. Do not use your telephone.
• Get everyone out of the building and away from the area immediately.
• Close all propane (LP) gas tank or cylinder fuel supply valves, or the main fuel supply valve located at the meter if you use natural gas.
• Propane (LP) gas is heavier than air and may settle in low areas. When you have reason to suspect a propane leak, keep out of all low areas.
• Use your neighbor’s phone and call your fuel gas supplier and your fire department. Do not re-enter the building or area.
• Stay out of the building and away from the area until declared safe by the firefighters and your fuel gas supplier.
• FINALLY, let the fuel gas service person and the firefighters check for escaped gas. Have them air out the building and area before you return. Properly trained service people must repair any leaks, check for further leakages, and then relight the appliance for you.

ODOR FADING -NO ODOR DETECTED

• Some people cannot smell well. Some people cannot smell the odor of the man-made chemical added to propane (LP) or natural gas. you must determine if you can smell the odorant in these fuel gases.

• Learn to recognize the odor of propane (LP) gas and natural gas. Local propane (LP) gas dealers will be more than happy to give you a scratch and sniff pamphlet. use it to become familiar with the fuel gas odor.

• Smoking can decrease your ability to smell. Being around an odor for a period of time can affect your sensitivity to that particular odor. odors present in animal confinement buildings can mask fuel gas odor.

• The odorant in propane (lP) gas and natural gas is colorless and the intensity of its odor can fade under some circumstances.

• If there is an underground leak, the movement of gas through the soil can filter the odorant.

• Propane (LP) gas odor may differ in intensity at different levels.
  Since Propane (LP) gas is heavier than air, there may be more odor at lower levels.

• always be sensitive to the slightest gas odor. if you continue to detect any gas odor, no matter how small, treat it as a serious leak. Immediately go into action as discussed previously.

ATTENTION-CRITICAL POINTS TO REMEMBER!

• Propane (LP) gas has a distinctive odor. Learn to recognize these odors. (Reference Fuel Gas Odor and Odor Fading sections to the left and above).
• Even if you are not property trained in the service and repair of the heater, AlwAyS be consciously aware of the odors of propane (LP) gas and natural gas.
• If you have not been properly trained in repair and service of propane (LP) gas then do not attempt to light heater, perform service or repairs, or make any adjustments to the heater on the propane (LP) gas fuel system.
• A periodic sniff test around the heater or at the heater’s joints; i.e. hose, connections, etc., is a good safety practice under any conditions. if you smell even a small amount of gas, CONTACT YOUR FUEL GAS SUPPLIER IMMEDIATELY. DO NOT WAIT!
