monoxide poisoning resemble the u, with head-

aches, dizziness or nausea. If you have these signs,

the heater may not be working properly. Get fresh

air at once! Have heater serviced. Some people

are more affected by carbon monoxide than others.

These include pregnant women, people with heart

or lung disease or anemia, those under the inuence

of alcohol and those at high altitudes.

pane/LP gases are odorless. An odor-making

agent is added to these gases. The odor helps you

detect a gas leak. However, the odor added to the

gas can fade. Gas may be present even though no

odor exists.

Make certain you read and understand all warn-

ings. Keep this manual for reference. It is your

guide to safe and proper operation of this heater.

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.

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 com-

municating 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

Use this work sheet to determine if you have a

conned or unconned space.

 Includes the room in which you will install

heater plus any adjoining rooms with doorless pas-

sageways 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. (length) x 16 ft.

(width) x 8 ft. (ceiling height) = 2,560 cu. 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. 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. (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 replace __________ 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 replace + __________ 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)

73,000 Btu/Hr (actual amount of

Btu/Hr used)

The space in the 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 ad-

ditional fresh air. Your options are as follows:

A. Rework worksheet, adding the space of an adjoin-

ing room. If the extra space provides an unconned

space, remove door to adjoining room or add

ventilation grills between rooms. See Ventilation

Air From Inside Building, page 7.

B. Vent room directly to the outdoors. See Ventila-

tion Air From Outdoors, page 7.

C. Install a lower Btu/Hr replace, if lower Btu/Hr

size makes room unconned.

unconned space, you must provide two permanent

openings: one within 12" of the ceiling and one

within 12" of the oor on the wall connecting the

two spaces (see options 1 and 2, Figure 2). You

can also remove door into adjoining room (see

option 3, Figure 2). Follow the National Fuel Gas

Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for

Provide extra fresh air by using ventilation grills or

ducts. You must provide two permanent openings:

one within 12" of the ceiling and one within 12"

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 thermostat-

controlled power vent. Heated air entering the attic

will activate the power vent.
