FRESH AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall not be installed in a confined space or unusually tight construction unless provisions 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.

Today’s homes are built more energy efficient than ever. New materials, increased insulation, and new construction methods help reduce heat loss in homes. Home owners weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, home owners want their homes as airtight as possible.

While it is good to make your home energy efficient, your home needs to breathe. Fresh air must enter your home. All fuel-burning appliances need fresh air for proper combustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air from the house to operate. You must provide adequate fresh air for these appliances. This will insure proper venting of vented fuelburning appliances.

PROVIDING ADEQUATE VENTILATION

The following are excerpts from National Fuel Gas Code. NFPA 54/ANS 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 4 through 6 will

help you classify your space and provide adequate ventilation.

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:

a. walls and ceilings exposed to the

outside atmosphere have a continuous water vapor retarder with a rating of one perm (6 x 10 per pa-sec-m2) or less with openings gasketed or sealed

b. weather stripping has been

added on openable windows and doors

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

From Outdoors

If your home does not meet all of the three criteria above, proceed

and

Deter-

Confined and Unconfined Space

The National Fuel Gas Code, ANS Z223.1

defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 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 m3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating 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 provided for adequate combustion and ventilation air.

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

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 x width x height). Length x Width x Height = _________________ cu. ft. (volume of space)

Example:

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)

Example:

3. Add the Btu/Hr of all fuel burning appliances in the space. Vent-free heater ______________ Btu/Hr Gas water heater* ______________ Btu/Hr Gas furnace ______________ Btu/Hr Vented gas heater ______________ Btu/Hr Gas fireplace logs ______________ Btu/Hr Other gas appliances* + ______________ Btu/Hr Total = ______________ 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:

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 adjoin-

ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 6.

B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6. C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.

If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation.

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

2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum Btu/Hr the space can support)

Example:

Gas water heater 44,000 Btu/Hr Vent-free heater + 10,000 Btu/Hr Total = 54,000 Btu/Hr

51,200 Btu/Hr (maximum the space can support) 54,000 Btu/Hr (actual amount of Btu/Hr used)

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

105564

National Fuel Gas Code, ANS Z223.1, Section 5.3

or applicable local codes.

Do not

CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe 3/8" diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.

Installation must include an equipment shutoff valve, union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 13).

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.

Pressure Regulator

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.

CAUTION: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

Install sediment trap in supply line as shown in Figure 13. Locate sediment trap where it is within reach for cleaning. Locate 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.

IMPORTANT:

Hold pressure regulator with wrench when connecting it to gas piping and/or fittings

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.

A. This appliance has a pilot which must

be lighted by hand. When lighting the pilot, follow these instructions exactly .

B. 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 electric 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.

C. Use only your hand to push in or tur n

D. Do not use this appliance if any part

has been under water . Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.

1. STOP! Read the safety information, column 1.

2. Make sure equipment shutoff valve is fully open.

3. Push in control knob slightly and tur n clockwise to the OFF position (see Figure 18). Be sure that the temperature setting knob is set at the line between level 1 and level 7.

4. Wait five minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety information in column 1. If you don’t smell gas, go to the next step.

5. Push in and turn control knob counterclockwise to PILOT position. Press in control knob for f i ve (5) seconds.

Note:

heater for the first time after hooking up to gas supply. If so, you may need to press in control knob for 30 seconds. This will allow air to bleed from the gas system.

6. Release downward pressure on control knob and turn clockwise to OFF position.

7. Press in control knob and turn counterclockwise past IGN to PILOT (see Figure 18). This will cause the piezo ignitor to spark and light the pilot gas. Keep control knob depressed for 10 seconds before releasing. If needed, repeat steps 5 through 7 until pilot lights.

THERMOSTAT

CONTROL

OPERATION

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

PILOT

IGN

OFF

Pilot Burner

on when room temperature drops below the set temperature. The control knob can be set to any comfort level between 1 and 7.

Note:

The thermostat sensing bulb measures the temperature of air near the heater cabinet. This may not always agree with room temperature (depending on housing construction, installation location, room size, open air temperatures, etc.) Frequent use of your heater will let you determine your own comfort levels.

MANUAL LIGHTING

PROCEDURE

1. Follow steps 1 through 5 under Lighting Instructions, page 12.

2. With control knob pressed in, strike match. Hold match to pilot until pilot lights.

3. Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob . Follow steps 8 and 9 under Lighting Instruc- tions, page 12.

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 incorrect 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, page 11 for non-thermostat models or page 12 for thermostat model)

• see Troubleshooting, pages 14 through 16

Thermocouple

Pilot Burner

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

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

If burner flame pattern is incorrect, as shown in Figure 23

• turn heater off (see To Turn Off Gas to Appliance, page 11 for non-thermostat models or page 12 for thermostat model)

• see Troubleshooting, pages 14 through 16

CLEANING AND

ODS/PILOT AND BURNER

• Use a vacuum cleaner, pressurized air, or 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 PSI. 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, pilot for dust and dirt.

3. Blow air through the ports/slots and

holes in the burner.

Clean the pilot assembly also. 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 drinking straw if compressed air is not available.

Warranty part(s) MUST be obtained through authorized dealers of this product and/or DESA International who will provide original factory replacement parts. Failure to use original factory replacement parts voids this warranty. The heater MUST be installed by a qualified installer in accordance with all local codes and instructions furnished with the unit.

This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that fail or become damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by improper installation. Travel, diagnostic cost, labor, transportation and any and all such other costs related to repairing a defective heater will be the responsibility of the owner.

TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE OF THE PRODUCT; THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED WARRANTIES AND LIMITS THE DURATION OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE TO TWO (2) YEARS FROM THE DATE OF FIRST PURCHASE; AND DESA INTERNATIONAL’S LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA INTERNATIONAL SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.

Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of incidental or consequential damages, so the above limitation on implied warranties, or exclusion or limitation on damages may not apply to you.

This warranty gives you specific legal rights, and you may also have other rights that vary from state to state. For information about this warranty write:
