AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall not be installed in a confined space or unusually tight construction unless pro visions are provided for adequate combustion and ventilation air. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home.

Providing Adequate Ventilation

The following are excerpts from National Fuel Gas Code, NFPA 54/ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation. All spaces in homes fall into one of the three following ventilation classifications:

1. Unusually Tight Construction

2. Unconfined Space

3. Confined Space

The information on pages 5 through 6 will help you classify your space and provide adequate ventilation.

Confined and Unconfined Space

The National Fuel Gas Code, ANSI Z.

defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m 3 per kw) of the aggregate input rating of all appliances installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour

(4.8 m 3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms connecting directly with the space in which the appliances are installed*, through openings not furnished with doors, are considered a part of the unconfined space.

This heater shall not be installed in a confined space or unusually tight construction unless provisions are pro vided for adequate combustion and ventilation air.

* Adjoining rooms are connecting only if there are doorless passageways or ventilation grills between them.

Unusually Tight Construction

The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation. How ever, in buildings of unusually tight construction, you must provide additional fresh air.

Unusually tight construction is defined as construction where: a) Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one perm (6×10 -11 kg per pa-sec-m 2 ) or less with openings gasketed or sealed and b) Weather stripping has been added on openable windows and doors and c) 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 at other openings.

If your home meets all of the three criteria above, you must provide additional fresh air. See “Ventilation Air From

Outdoors”. If your home does not meet all of the three criteria above, proceed to “Determining Fresh-Air Flow

For Heater Location” .

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Confined or Unconfined Space

Use this worksheet to determine if you have a confined or unconfined space.

Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms.

1. Determine the volume of the space

Length×Width×Height= cu.ft. (volume of space)

Example: Space size 20ft. (length)×16ft. (width)×8ft. (ceiling height) =2560cu. ft. (volume of space)

If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space.

2. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.

(volume of space)÷50 cu. ft.=(Maximum Btu/Hr the space can support)

3. Add the Btu/Hr of all fuel burning appliances in the space.

Example:

Gas water heater 30,000 Btu/Hr

Vent-free heater + 26,000 Btu/Hr

Total = 56,000 Btu/Hr

*Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.

4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.

Btu/Hr (maximum the space can support)

Btu/Hr (actual amount of Btu/Hr used)

Example : 51,200 Btu/Hr(maximum the space can support)

56,000 Btu/Hr(actual amount of Btu/Hr used)

The space in the above example is a confined space because the actual Btu/Hr used is more than the maximum

Btu/Hr the space can support.

You must provide additional fresh air. Your options are as follows: a) Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grills between rooms. See “ Ventilation Air From

Inside Building”.

b) Vent room directly to the outdoors. See “Ventilation Air From Outdoors”.

c) Install a lower Btu/Hr heater if lower Btu/Hr size makes room unconfined.

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.

Ventilation Air From lnside Building

This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two perma nent openings: one within 12 inches of the ceiling and one within 12 inches of the floor on the wall connecting the two spaces (see options 1 and 2,

Figure 2). You can also remove the door into adjoining room (see option

3, Figure 2). Follow the National Fuel Gas Code. NFPA 5/ANSI Z.,

Section 5., Air for Combustion and Ventilation for required size of ventila tion grills or ducts.

Figure 1 - Ventilation Air from Outdoors

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent openings: one within 12 inches of the ceiling and one within

12 inches of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Fol low the National Fuel Gas Code, NFPA 5/ANSI Z., Section 5., Air for

Combustion and Ventilation for required size of ventilation grills or ducts.

IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a thermostat-controlled power vent. Heated air entering the attic will activate the power vent. Rework worksheet, adding the space of the adjoining unconfined space. The combined spaces must have enough fresh air to supply all appliances in both spaces.

UNPACKING

1. Remove heater from carton.

2. Remove all protective packaging applied to heater for shipping

3. Check heater for any shipping damage. If heater is damaged, promptly inform dealer where you bought heater.

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 (.3 KWs) of gas input per hour.

Unvented room heaters are recommended as supple mental heat (a room) rather than a primary heat source

(an entire house). In most supplemental heat applica tions, the water vapor does not create a problem. In most applications, the water vapor enhances the low humidity atmosphere experience during cold weather.

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

1. Be sure the heater is sized properly for the ap plication, 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.

NOTICE: This heater is intended for use as supplemental heat. Use this heater along with your primary heat ing system. Do not install this heater as your primary heat source. If you have a central heating system, you may run system’s circulating blower while using heater. This will help circulate the heat throughout the house. In the event of a power outage, you can use this heater as your primary heat source.

CAUTION: If you install the heater in a home garage:

Heater pilot and burner must be at least 18 inches above the floor.

Place heater where moving vehicle will not hit it.

WARNING: A qualified service person must install heater. Follow all local codes.

WARNING: Never install the heater in a bedroom or bathroom in a recreational vehicle where curtains, furniture, clothing, or other flammable objects are less than 36 inches from the front, top, or sides of the heater in high traffic areas in windy or drafty areas

WARNING: Maintain the minimum clearances shown in Figure

INSTALLATION

CONNECTING TO GAS SUPPLY

WARNING: A qualified service technician must connect heater to gas supply. Follow all local codes.

WARNING: This appliance requires a 3/8-inch NPT (National Pipe Thread) inlet connection to the pressure regulator.

WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

WARNING: Do not over tighten gas connections.

CAUTION: Use only new, black iron or steel pipe. Internally tinned copper tubing may be used in certain ar eas. Check your local codes. Use pipe of 1/2-in. diameter or greater to allow proper gas volume to heater.

If pipe is too small, undue loss of pressure will occur.

NATURAL GAS MODELS:

CAUTION: Check your gas line pressure before connecting heater to gas line. Gas line pressure must be no greater than 10.5 inches of water. If gas line pressure is higher, heater regulator damage could occur.

PROPANE MODELS:

CAUTION: Never connect heater directly to the gas supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and gas supply.

CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas piping and/or fittings.

CAUTION: Use pipe joint sealant that is resistant to gas (Propane or Natural Gas).

Typical Inlet Pipe Diameters

Use 3/8-inch black iron pipe or greater.

Installation must include an equipment shutoff valve, union, and plugged 1/8-inch

NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be up stream from heater (see Figure 12).

IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance.

Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves.

Figure 12- Gas Connection (inches) for NG

*A CSA/AGA design-certified equipment shutoff valve with 1/8-inch NPT tap is an acceptable alternative to test gauge connection. Purchase the optional

CSA/AGA design-certified equipment shutoff valve from your dealer.

The installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water.

If you do not reduce incoming gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 13. Pointing the vent down protects it from freezing rain or sleet.

Install sediment trap in supply line as shown in Figure 12.

Place sediment trap where it is within reach for cleaning. Place sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly.

Installation of Base Stand

Before installing heater to the base , please make sure you have the following items:

( 2 ) - Base ( 4 ) - Sheet Metal Screws

Installation Procedure:

THERMOSTAT CONTROL OPERATION

(ONLY FOR MN/L100TPH)

The thermostatic control used on this model differs from standard thermostats. Standard thermostats simply turn

on and off the burner. The thermostat used on this heater

senses the room temperature. At times the room may exceed the set temperature. If so, the burner will shut off.

The burner will cycle back on when room temperature drops below the set temperature. The control knob can be set to any comfort level between 1 and 5.

MN/L060HPH

Note: The thermostat sensing bulb measures the temperature of air near the heater cabinet. This may not always agree with

MN/L100TPH room temperature (depending on housing construction, installation location, room size, open air temperature, etc). Frequent use of your heater will let you determine your own comfort levels.

TO TURN OFF GAS TO APPLIANCE

Shutting Off Heater

Turn control knob clockwise to the OFF position.

Shutting Off Burner Only (pilot stays lit )

Turn control knob clockwise to the PILOT position.

Figure 19

INSPECTING BURNER

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 20 shows a correct pilot flame pattern. Figure 21 shows an in correct pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down. If pilot flame pattern is incorrect, as shown in Figure 21,

• turn heater off (see “To Turn Off Gas to Appliance” on page 15) see Troubleshooting pages 19 through 21.

WARNING: If yellow tipping occurs, your heater could produce increased levels of carbon monoxide. If burner flame pattern shows yellow tipping, follow instructions at bottom of this page.

Notice: Do not mistake orange flames with yellow tipping. Dirt or other fine particles enter the heater and burn causing brief patches of orange flame.

BURNER FLAME PATTERN

Figure 22 shows a correct burner flame pattern. Figure 23 shows an incorrect burner flame pattern. If burner flame pattern is incorrect, as shown in Figure 23,

Turn heater off (see “To Turn Off Gas to Appliance”).

See Troubleshooting , pages 19 through 21.

WARNING: Turn off heater and let cool before servicing

CAUTION: You must keep control areas, burner, and circulating air passageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service technician.

Heater may need more frequent cleaning due to excessive lint from carpet ing, bedding material, pet hair, etc.

ODS/PILOT AND BURNER

• Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean.

CLEANING BURNER PILOT AIR INLET HOLE

We recommend that you clean the unit every 2,500 hours of operation or every three months. We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using compressed air no greater than 30 PSl. Your local computer store, hardware store, or home center may carry compressed air in a can. You can use a vacuum cleaner in the blow position. If using compressed air in a can, please follow the directions on the can. If you don’t follow directions on the can, you could damage the pilot assembly.

1. Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.

2. Inspect burner and pilot for dust and dirt.

3. Blow air through the ports/slots and holes in the burner. Also clean the pilot assembly. A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see Figure 24). With the unit off, lightly blow air through the air inlet hole. You may blow through a drink ing straw if compressed air is not available.
