SAFETY

INFORMATION

Carbon Monoxide Poisoning: Early

signs of carbon monoxide poisoning re-

semble the flu, with headaches, dizziness,

or nausea. If you have these signs, the log set

may not be working properly. Get fresh air

at once! Have log set 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 influence of alcohol, and

those at high altitudes.

Natural Gas: Natural gas is odorless. An

odor-making agent is added to the gas. 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

Warnings. Keep this manual for reference.

PROVIDING ADEQUATE

VENTILATION

The following are excerpts from National

Fuel Gas Code. NFPA 54/ANS Z223.1, Sec-

tion 5.3, Air for Combustion and Ventila-

tion.

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 win-

dows 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-

fined as construction where:

a. walls and ceilings exposed to the

outside atmosphere have a con-

tinuous water vapor retarder with

a rating of one perm (6x10

-11

per pa-sec-m

) or less with open-

ings 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, be-

tween sole plates and floors, be-

tween wall-ceiling joints, be-

tween wall panels, at penetra-

tions for plumbing, electrical, and

gas lines, and at other openings.

If your home meets all of the three

criteria above, you must provide ad-

ditional fresh air. See

Ventilation Air

From Outdoors

, page 6.

If your home does not meet all of the

three criteria above, proceed to

De-

termining Fresh-Air Flow For Log Set

Location

, page 5.

Today’s homes are built more energy effi-

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

efficient, your home needs to breathe. Fresh

air must enter your home. All fuel-burning

appliances need fresh air for proper com-

bustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, and

fuel burning appliances draw air from the

house to operate. You must provide ad-

equate fresh air for these appliances. This

will insure proper venting of vented fuel-

burning appliances.

AIR FOR

COMBUSTION AND

VENTILATION

WARNING: This appliance

shall not be installed in a con-

fined space or unusually tight

construction unless provisions

are provided for adequate com-

bustion and ventilation air. Read

the following instructions to in-

sure proper fresh air for this and

other fuel-burning appliances in

your home.

Confined and Unconfined Space

The National Fuel Gas Code (ANS Z223.1,

1992 Section 5.3) defines a confined space

as a space whose volume is less than 50

cubic feet per 1,000 Btu per hour (4.8 m

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

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 in-

stalled*, through openings not furnished

with doors, are considered a part of the

unconfined space.

This log set shall not be installed in a con-

fined 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 ventila-

tion grills between them.

OWNER’S MANUAL

DETERMINING FRESH-AIR FLOW FOR APPLIANCE LOCATION

Determining if You Have a Confined or Unconfined Space

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

Space: Includes the room in which you will install appliance 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. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2560 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. 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 the space can support)

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

Gas fireplace logs _____________ Btu/Hr

Gas water heater* _____________ Btu/Hr

Gas furnace _____________ Btu/Hr

Vented gas heater _____________ Btu/Hr

Vent-free heater _____________ 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:

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

95,000 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 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.

VENTILATION

Continued

Example:

Gas water heater 40,000 Btu/Hr

Gas fireplace logs + 55,000 Btu/Hr

Total = 95,000 Btu/Hr

Continued

WARNING: If the area in which the appliance 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, 1992, Section 5.3

or applicable local codes.

Ventilation Air From Inside

Building

This fresh air would come from an adjoining

unconfined space. When ventilating to an

adjoining unconfined space, you must pro-

vide two permanent openings: one within

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

floor on the wall connecting the two spaces

(see options 1 and 2, Figure 2). You can also

remove door into adjoining room (see op-

tion 3, Figure 2). Follow the National Fuel

Gas Code NFPA 54/ANS Z223.1, Section

5.3, Air for Combustion and Ventilation for

required size of ventilation grills or ducts.

WARNING: Rework work-

sheet, adding the space of the

adjoining unconfined space. The

combined spaces must have

enough fresh air to supply all

appliances in both spaces.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation

grills or ducts. You must provide two per-

manent openings: one within 12" of the

ceiling and one within 12" of the floor.

Connect these items directly to the outdoors

or spaces open to the outdoors. These spaces

include attics and crawl spaces.

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.

CONNECTING TO GAS

SUPPLY

WARNING: A qualified ser-

vice person must connect log set

to gas supply. Follow all local

codes.

Installation Items Needed

Before installing log set, make sure you

have the items listed below.

• piping (check local codes)

• sealant (resistant to LP gas)

• manual shutoff valve

• test gauge connection

• adjustable (crescent) wrench or pliers

• sediment trap

• tee joint

• pipe wrench

CAUTION: Use only new,

black iron or steel pipe. Inter-

nally-tinned copper tubing may

be used in certain areas. Check

your local codes. Use pipe of 1/2"

diameter or greater to allow

proper gas volume to log set. If

pipe is too small, undue loss of

pressure will occur.

Install sediment trap in supply line as shown

in Figure 6. 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 log set controls. If sediment trap is not

installed or is installed wrong, log set may

not run properly.

Installation must include a manual 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

log set (see Figure 6).

Apply pipe joint sealant lightly to male

threads. This will prevent excess sealant

from going into pipe. Excess sealant in pipe

could result in a clogged burner injector.

CAUTION: Use pipe joint seal-

ant that is resistant to liquid pe-

troleum (LP) gas.
