AIR FOR
COMBUSTION AND
VENTILATION

WARNING: This heater shall

not be installed insconfined space
or unusually tight construction

unless provisions are provided

for adequate combustion and ven-
tilation air. Read the following in-
structions 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
helpreduce heat loss in homes. Home owners

weather strip and caulk around windows and

doors tokeep the cold airout 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.

PROVIDING ADEQUATE

VENTILATION

The following are excerpts from National
Fuel Gas Code. NFPA 54/ANS Z223.1, Sec-
tion 5.3,Airfor Combustion and Ventilation.

All spaces in homes fall into one ofthe 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 (6 x 10"11kg
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

Co

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, electdeal, 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 Heater
Location, page 5.

Confined Space and Unconfined
Space

TheNational Fuel Gas Code (ANS Z2123.1,
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
unconfined 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 ofalI 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.

* Adjoining rooms are communicating only
if there 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 work sheet 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 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.

Vent-free heater Btu/Hr Example:
Gas water heater* Btu/Hr Gas water heater 40,000 Btu/Hr

Gas furnace Btu/Hr Vent-free heater + 39,000 Btu/Hr
Vented gas heater Btu/Hr Total 79,000 Btu/Hr
Gas fireplace logs 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)

79,000 Btu/Hr (actual amount of Btu/Hr used)

The space in the above exampleis 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.

_lL WARNING: Ifthe 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, 1992, Section 5.3 or applicable local codes.

INSTALLING DAMPER

CLAMP ACCESSORY FOR
VENTED OPERATION

Note:When used as a vented heater, appli-

ance must be installed only in a solid-fuel
burning fireplace with a working flue and

constructed of noncombustible material.
If your heater isa manually controlled model,

you may use this heater as a vented product.
There are three reasons for operating your

heater in the vented mode.

1. The fireplace does not meet the clear-
ance to combustibles requirements for

vent-free operation.

2. State or local codes do not permit vent-
free operation.

3. You prefer vented operation.

If reasons number 1 or 2 above apply to you,
you must permanently open chimney flue

damper. You must install the damper clamp
accessory (to order, see Accessories, page

27). This will insure vented operation (see

Figure 10). The damper clamp will keep
damper open. Installation instructions are

included with clamp accessory.
See chart below for minimum permanent

flue opening you must provide. Attach
damper clamp so the minimum permanent
flue opening will be maintained at all times.

ASSEMBLY

CAUTION: Do not remove the

metal data plates attached to the
heater base assembly. The data
plates contain Important warranty

information.

WARNING: You must secure

this heater to fireplace floor. If

not, heater will move when you

adjust controls. Moving heater
may cause a gas leak.

WARNING: If Installing in a

sunken fireplace, special care Is
needed. You must raise the fire-

place floor to allow access to
heater control panel. This will in-
sure adequate air flow end guard
against sooting. Raise fireplace

floor with noncombustible mate-
rial. Make sure metadal is secure.

CAUTION: Do not pick up

heater base assembly by the
burner. This could damage
heater. Only handle base assem-
bly by grates.

Installation Items Needed

• hardwarepackage (provided with heater)

• approved flexible gas hose (not provided)

(if allowed by local codes)

• sealant resistant to propane/LP gas, not

provided

• electric drill with 3/I 6" masonry drill bit
Note: Install optional remote receiver and

hand-held remote kit (see Accessories, page

27) before installing gas log heater. See in-
stallation instructions included with the kit.

1. Apply pipe joint sealant lightly to male
threads of the fitting to be threaded into

gas regulator. Connect approved flex-

ible gas hose to gas regulator of heater
(see Figure 11, page 11).

2. Locate masonry screws in hardware
package.

3. Position heater base assembly in
fireplace.

4. Mark screw locations through holes in
mounting flanges (see Figure 12, page

11). If installing in a brick-bottom fire-

place, mark screw locations in mortar

joint of bricks.

5. Remove heater base from fireplace.

6. Drill holes at marked locations using
3/16" masonry drill bit.

IMPORTANT." Make sure the heater burn-
ers are level. If heater isnot level, heater will

CONNECTING TO GAS
SUPPLY

I _1= WARNING: A qualified service

person must connect heater togas
supply. Follow all local codes.

_lt CAUTION: Never connect heater

directlytothepropane/LPsupply.

This heater requires an extemal
regulator (not supplied). Install the
external regulator between the
heater and propane/LP supply.

Installation Items Needed

Before installing heater, make sure you have
the items listed below.

• piping (check local codes)

• sealant (resistant to propane/LP gas)

• manual shutoff valve *

• test gauge connection *

• sediment trap

• tee joint

• pipe wrench
* An A.G.A. design-certified manual shutoff

valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Pur-

chase the optional A.G.A. design-certified
manual shutoff valve from your dealer. See

Accessories, page 27.
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

13. Pointing the vent down protects it from

freezing rain or sleet.

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. It

pipe is too small, undue loss of
pressure will occur.

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 14).
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.

• k 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 14. Locate sediment trap where it is

within reach forcleaning. Locate sediment trap
where trappedmatter is not likely to freeze. A

sediment trap trapsmoisture andcontaminants.

This keeps them from going into heater con-

trois. If sediment trap is not installed or is
installed wrong, heater may not run properly.

• k CAUTION: Avoid damage to

regulator. Hold gas regulator with
wrench when connecting It to gas

piping and/or fittings.

CLEANING AND

MAINTENANCE

_k WARNING: Turn off heater
and let cool before cleaning.

_[_ CAUTION: You must keep

control areas, burner, and circu-
lating air passageways of heater

clean. Inspect these areas of
heater before each use. Have

heater inspected yearly by a quali-
fied service person. Heater may
need more frequent cleaning due
to excessive lint from carpeting,

pet hair, etc.

CLEANING BURNER
INJECTOR HOLDER AND

PILOT AIRINLET HOLE

The primary air inlet holes allow the proper
amount of air to mix with the gas. This

provides a clean burning flame. Keep these
holes clearofdust, dirt, and lint. Clean these

air inlet holes prior to each heating season.
Blocked air holes will create soot. We rec-

ommend that you clean the unit every 2,500
hours of operation or every three months.

We alsorecommend thatyou keep the burner
tube and pilot assembly clean and free of

dust and dirt. To clean these parts we recom-
mend using compressed air no greater than
30 PSI. Your local computer store, hard-
ware store, or home center may carry com-

pressed air in a can. You can use a vacuum
cleaner in the blow position. If using com-

pressed air in a can, please follow the direc-
tions on the can. If you don't follow direc-
tions on the can, you could damage thepilot
assembly.

1. Shut off the unit, including the pilot.

Allow the unit to cool for at least thirty
minutes.

2. Inspect burner, pilot, and primary air
inlet holes on injector holder for dust
and dirt (see Figure 37).

3. Blow air through the ports/slots and
holes in the burner.

4,

Check the injector holder located at the
end of the burner tube again. Remove

any large particles of dust, dirt, lint, or
pet hairs with a soft cloth or vacuum

cleaner nozzle.

5. Blow air into the primary air holes on
the injector holder.

6. In case any large clumps of dust have
now been pushed into the burner repeat
steps 3 and 4.

Clean the pilot assembly also. 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 38). With the unit off, lightly

blow air through the air inlet hole. You may

blow through a drinking straw if compressed
air is not available.
