WAT E R VA P O R : A B Y- P R O D U C T O F U N V E N T E D R O O M H E AT E R S

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 BTU’s

(.3KW’s) of gas input per hour.

Unvented room heaters are recommended 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 insure 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.

FRESH AIR FOR

COMBUSTION AND

VENTILATION

WARNING: This heater shall not be installed in a confined space or unusually t i g h t c o n s t r u c t i o n u n l e s s provisions are provided for adequate combustion and v e n t i l a t i o n a i r . R e a d t h e f o l l o w i n g i n s t r u c t i o n s t o insure proper fresh air for this and oth er f uel-bu rni ng appliances in your home.

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, l 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, page 6.

If your home does not meet all of the three criteria abov, see Determining

Fresh-Air Flow for Heater Location, page 4, 5.

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 h o u r ( 4 . 8 m 3 p e r k w ) o f t h e 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 h o u r ( 4 . 8 m 3 p e r k w ) o f t h e aggregate input rating of all appliances installed in that space.

Rooms communicating directly with t h e s p a c e i n w h i c h t h e 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 t i g h t c o n s t r u c t i o n u n l e s s p r o v i s i o n s a r e p r o v i d e d f o r adequate combustion and ventilation air.

* A d j o i n i n g r o o m s a r e 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

× width

× height).

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)

Example: 2560 cu. ft. (volume of space) 50 cu.ft.=51.2 or 51,200(maximum Btu/Hr t he space can support)

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, ANS Z223.1, Section 5.3

or applicable local codes.

4

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

Example:

Gas water heater 40,000 Btu/Hr

Vent free heater + 20,000 Btu/Hr

Total = 60,000 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)

60,000 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, page 5.

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.

INSTALLATION

CONNECTING TO GAS SUPPLY

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

WARNING: This appliance requires a 3/8

"

NPT (National

Pipe Thread) inlet connection to the pressure regulator.

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

IMPORTANT: 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.

CAUTION: Use only new, b l a c k i r o n o r s t e e l p i p e .

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.

I f p i p e i s t o o s m a l l , undue loss of pressure will occur.

Typical Inlet Pipe Diameters

All models up to 20,000 BTU’s use

3/8’’ or greater pipe;

All models 25,000 BTU’s and higher, use 1/2” or greater pipe.

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).

Figure 13 -Gas Connection

*A CSA/AGA design-certified equipment shutoff valve with 1/8

"

NPT tap is an acceptable alternative to test gauge connection. Purchase the CSA/AGA design-certified equipment shutoff valve from your dealer.

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.

Install sediment trap in supply line as shown in Figure 13. Locate sediment trap where it is within r e a c h f o r c l e a n i n g . L o c a t e 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 i n s t a l l e d w r o n g , h e a t e r m a y not run properly.

CAUTION: Use pipe joint sealant that is resistant to natural gas.

IMPORTANT: Hold pressure r e g u l a t o r w i t h w r e n c h w h e n connecting it to gas piping and/or fittings.

CLEANING 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, pilot for dust

and dirt.

3. Blow air through the ports/slots

and holes in the bumer.

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 drinking straw if comp r e s s e d a i r i s n o t a v a i l a b l e .
