COMBUSTION AND

VENTILATION

WARNING: This heater shall

not be installed In aconfined

space unless provisions are pro-

vided for adequate combustion

and ventilation air. Read the fol-

lowing instructions to insure

proper fresh air for this and other

fuel-burning appliances in your

home.

Today's homes are built more energy effi-

cient than ever. New materials, increased

insulation, and new construction methods

helpreduceheatloss inhomes. Home owners

weather sl_p and caulk aroundwindows and

doorstokeepthecdd ah"outandthewarm air

in. During heating months, home owners

want their homes as airtight as possible.

While itis 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.

Exhaustfans,fireplaces, clothes dryers,and

fuel burningappfiances draw airfrom the

house to operate. You must provide ad-

equateflesh air for these appliances.This

will insure proper ventingof vented fuel-

burningappliances.

PROVIDING ADEQUATE

VENTILATION

The following is excerpts from National

Fuel Gas Code. NFPA 54/ANSI 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 4through 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 flesh 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 celllngs exposed to the

outside atmosphere have a con-

tinuous water vapor retarder with

a rating of one penn (6 x 10-11kg

per pa-sec-nd) or less with open-

Ings gasketad or sealed and

b. weather stripping has been

added on openable windows and

doors and

€. caulldng 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 st other openings.

ff your home meets all of the three

¢riterle 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 ¢dteda above, proceed to Dater.

mining Fresh-Air Flow for Heater Lo-

cation, page S.

Confined and Unconfined Space

The National Fuel Gas Code (ANSI 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 m3per

kw) of the aggregate input rating of all

appLiances installed in that space and an

unconfialng space as a space whose volume

is not less than 50 cubic feet per 1,000 Btu

per hour (4.8 m3per 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 heater shall not be installed in a con-

fined space or unusually tight construction

unless provisions are provided for adequate

combustion and ventilation air.

*Adjoiningroomsare communicatingonly

ifthere are doorless passageways or ventila-

tion 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 installheater plus any adjoining rooms with doorless passageway sor ventilation gillls between

the rooms.

1. Determine the volume of the space (length x width x height).

Length xWidth x Height = cu. ft. (volume of space)

Example: Space size 20 ft, (length) x 16 ft. (width) x 8ft, (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. 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 (actual amount of Btu/Hr used)

Example: 51,200 Btu/Hr (maximum the spacecansupport)

60,000 Btu/Hr (actual amount of Btu/Hr used)

The space intbe above example is aconfined 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-

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

B. VeatroomcYu'ecflytotheoutdoors. SeeVentilationAirFromOutdoors, page6.

C. Install a lower Btu/Hr heater, ff lower Btu/Hr size makes room unconfined.

Iftbe 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

adflitional fresh airventilation.

CONNECTING TO GAS

SUPPLY

NOTICE: A qualified service per-

son must connect heater to gas

supply. Follow all local codes.

CAUTION: Never connect

heater directly to the propane/LP

supply. This heater requires an

external regulator (not supplied).

Install the external regulator be-

tween the heater and propane/LP

supply.

The installer must supply an external regu-

lator. 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 incom-

ing gas pressure, heater regulator damage

could occur. Install external regulator with

the vent pointing down as shown in Figure

12. Pointing the vent down protects it from

freezing rain or sleet.

_IL 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 heater. If

pipe is too small, undue loss of

pressure will occur.

Typical Inlet Pipe Diameters

20,000 Btu/Hr models 3/8" or greater

30,000 Btu/Hr models 1/2" or greater

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

heater (see Figure 13).

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.

Pressure

Regulator

CAUTION: Use pipe joint seal-

ant that is resistant to liquid pe-

troleum (LP) gas.

Install sediment trap in supply line as shown

in Figure 13. Locate sediment trap where it

is within reach for cleaning. Locate sedi-

ment 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 pip-

ing and/or fittings.
