AIR FOR COMBUSTION

AND VENTILATION

WARNING: This heater shall

not be installed in a conned 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 efcient 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 efcient, 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, replaces, 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 fuel-burning appliances.

PROVIDING ADEQUATE VENTILATION

The following are excerpts from National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation.

All spaces in homes fall into one of the three following ventilation classications:

1. Unusually Tight Construction

2. Unconned Space

3. Conned Space

The information on pages 5 through 7 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 dened 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

-11

per pa-sec-m2) 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 these three criteria, you must provide additional fresh air. See Ventilation Air From Outdoors, page 7.

If your home does not meet all of the three criteria above, proceed to Determining Fresh-Air Flow For Heater Location, page 6.

Conned and Unconned Space

The National Fuel Gas Code, ANSI Z223.1/NFPA 54 denes a conned 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 unconned 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 unconned space.

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

Page 6

www.desatech.com

117001-01B6

The space in the above example is a conned 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 Ventila-

tion Air From Outdoors, page 7.

C. Install a lower Btu/Hr heater, if lower Btu/Hr size

makes room unconned.

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

WARNING: If the area in

which the heater may be operated is smaller than that dened as an unconned 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 Section 5.3

or applicable local codes.

VENTILATION AIR

Ventilation Air From Inside Building

This fresh air would come from an adjoining unconned space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12" (30.5 cm) of the ceiling and one within 12" (30.5 cm) of the oor on the wall connecting the two spaces (see options 1 and 2, Figure 2, page 7). You can also remove door into adjoining room (see option 3, Figure 2, page 7). Follow the National Fuel Gas

Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation for required size of

ventilation grills or ducts.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Conned or Unconned Space

Use this work sheet to determine if you have a conned or unconned 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: Space size 20 ft. (6.1 m) (length) x 16

ft. (4.88 m) (width) x 8 ft. (2.44 m) (ceiling height) = 2560 cu. ft. (72.49 m3) (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. Multiply the space volume by 20 to determine the maximum Btu/Hr the space can support.

__________ (volume of space) x 20 = (Maxi-

mum Btu/Hr the space can support)

Example: 2,560 cu. ft. (72.49 m3) (volume of

space) x 20 = 51,200 (maximum Btu/Hr the space can support)

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 replace logs ___________ Btu/Hr Other gas appliances* + __________ Btu/Hr Total = __________ Btu/Hr * Do not include direct-vent gas appliances. Di-

rect-vent draws combustion air from the outdoors and vents to the outdoors.

Example:

Gas water heater ___________ Btu/Hr Vent-free heater + __________ Btu/Hr Total = __________ Btu/Hr

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)

AIR FOR COMBUSTION

AND VENTILATION

Continued

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent openings: one within 12" (30.5 cm) of the ceiling and one within 12" (30.5 cm) of the oor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the National Fuel Gas

Code, ANSI Z223.1/NFPA 54, Section 5.3, 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 thermostatcontrolled power vent. Heated air entering the attic will activate the power vent.

WARN ING: F or na tural

gas, never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

IMPORTANT: For natural gas, check 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.

CAUTION: For propane/LP gas, never connect heater directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and propane/LP supply.

For propane/LP gas, 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 the external regulator with the vent pointing down as shown in Figure 12. Pointing the vent down protects it from freezing rain or sleet.

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 of large enough diameter to allow proper gas volume to heater. If pipe is too small, undue loss of volume will occur.

IMPORTANT: Hold the pressure regulator with wrench when connecting it to gas piping and/or ttings. Do not over tighten pipe connection to regulator. The regulator body could be damaged.

CHECKING GAS CONNECTIONS

WARNING: Test all gas piping

and connections, internal and external to unit, for leaks after

installing or servicing. Correct all leaks at once.

WARNING: Never use an

open ame to check for a leak. Apply a noncorrosive leak detection uid to all joints. Bubbles forming show a leak. Correct all leaks at once.

CAUTION: For propane/LP gas, make sure external regulator has been installed between propane/LP supply and heater. See guidelines under Connect- ing to Gas Supply, page 10.

PRESSURE TESTING GAS SUPPLY PIPING SYSTEM

Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)

1. Disconnect appliance with its appliance main gas valve (control valve) and equipment shutoff valve from gas supply piping system. Pressures in excess of 1/2 psig will damage heater regulator.

2. Cap off open end of gas pipe where equipment shutoff valve was connected.

3. Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas or using compressed air.

4. Check all joints of gas supply piping system. Apply a noncorrosive leak detection uid to all joints. Bubbles forming show a leak.

5. Correct all leaks at once.

6. Reconnect heater and equipment shutoff valve to gas supply. Check reconnected ttings for leaks.

Installation must include 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.

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

WARNING: 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.

to the oor because some gas is heavier than air and will settle on the oor.

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 ph one. Fol low the gas supplier’s instructions.

• If you cannot reach your gas supplier, call

the re department.

C. 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 qualied service

technician. Force or attempted repair may

result in a re or explosion.

D. Do not use this appliance if any part has

been under water. Immediately call a

qualied service technician to inspect the

appliance and to replace any part of the control system and any gas control which has been under water.

Note: You may be running this heater for the rst time after hooking up to gas supply. If so, you may need to press in control knob for 30 seconds or more. This will allow air to bleed from the gas system. If needed, keep pressing ignitor button until pilot lights. If ignitor does not light pilot, refer to Troubleshooting, page 16 or contact a qualied service person or gas supplier for repairs. Until repairs are made, light pilot with match. To light pilot with match, see Manual Lighting Procedure, page 14.

8. Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob.

• If control knob does not pop up when re-

leased, contact a qualied service person or gas supplier for repairs.

Note: If pilot goes out, repeat steps 4 thru 7.

Thermostat models have a safety interlock system. Wait one (1) minute before lighting pilot again.

9. Turn control knob counterclockwise to desired heating level. The main burner should light. Manual control heaters should be used in locked positions.

INSPECTING HEATER

Check pilot ame pattern and burner ame pattern often.

PILOT FLAME PATTERN

Figure 20 shows a correct pilot ame pattern. Figure 21 shows an incorrect pilot ame 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 ame pattern is incorrect, as shown in Figure 21

• turn heater off (see To Turn Off Gas to Appli- ance, page 13)

• see Troubleshooting, page 16

OPERATING HEATER

Continued

BURNER FLAME PATTERN

Figure 22, page 15, shows a correct burner ame pattern. Figure 23, page 15, shows an incorrect burner ame pattern. The incorrect burner ame pattern shows yellow tipping of the ame. It also shows the ame higher than 1/2 the glass panel height.

WARNING: If yellow tipping

occurs, your heater could pro-

duce increased levels of car-

bon monoxide. If burner ame pattern shows yellow tipping, proceed with the following instructions.

NOTICE: Do not mistake orange ames with yellow tipping. Dust or other ne particles enter the heater and burn causing brief patches of orange ame.

If burner ame pattern is incorrect, as shown in Figure 23, page 15,

• turn heater off (see To Turn Off Gas to Appli- ance, page 13)

• see Troubleshooting, page 16

Note: The pilot ame on natural gas units will have a slight curve, but ame should be blue and have no yellow or orange color.

THERMOSTAT CONTROL

OPERATION

The thermostatic control used on these models 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 heat level between 1 and 5. This adjusts the amount of gas ow to the burner that increases or decreases the burner ame height.

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. Remove front panel (see Figure 10, page 9).

2. Follow steps 1 through 7 under Lighting Instructions, page 13.

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

4. Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Now follow step 9, under Light- ing Instructions, page 13.

CLEANING AND

MAINTENANCE

WARNING: Turn off heater

and let cool before cleaning.

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 qualied service person. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.

WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.

ODS/PILOT AND BURNER

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

BURNER PILOT AIR INLET

The primary air inlet holes allow the proper amount of air to mix with the gas. This provides a clean burning ame. Keep these holes clear of dust, dirt and lint. Clean these air inlet holes prior to each heating season. Blocked air holes will create soot. We recommend that you clean the unit every three months during operation and have heater inspected yearly by a qualied service person.

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. 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.

4. Never insert objects into the pilot tube.

Clean the pilot assembly also. A yellow tip on the pilot ame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet about two inches from where the pilot ame comes out of the pilot assembly (see Figure 24). With the unit off, lightly blow air through the air inlet. You may blow through a drinking straw if compressed air is not available.
