OPERATION

This heater is clean burning. It requires no
outside venting. There is no heat loss out a
vent or up a chimney. Heat is generated by

both realistic ames and glowing coals. This

heater is designed for vent-free operation with
ue damper closed. It has been tested and ap­proved to ANSI Z21.11.2 standard for unvented
heaters. State and local codes in some areas
prohibit the use of vent-free heaters.

PRODUCT FEATURES

SAFETY DEVICE

This heater has a pilot with an Oxygen Deple­tion Sensing (ODS) safety shutoff system. The
ODS/pilot is a required feature for vent-free
room heaters. The ODS/pilot shuts off the
heater if there is not enough fresh air.

ELECTRONIC IGNITION SYSTEM

This heater has an electronic ignitor to light
heater fuel supply.

AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall
not be installed in a room or space
unless the required volume of
indoor combustion air is provided
by the method described in the

National Fuel Gas Code, ANSI
Z223.1/NFPA 54, the International
Fuel Gas Code, or applicable

local codes. Read the following
instructions to insure proper fresh
air for this and other fuel-burning
appliances in your home.

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. Dur-

ing 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.

PROVIDING ADEQUATE
VENTILATION

The following are excerpts from National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation.

All spaces in homes fall into one of the three

following ventilation classications:

1. Unusually Tight Construction

2. Unconned Space

3. Conned Space

The information on pages 6 through 8 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, you must provide

additional fresh air.

Unusually tight construction is dened as

construction where:
a. walls and ceilings exposed to the out-

side atmosphere have a continuous
water vapor retarder with a rating of

one perm (6 x 10

-11

kg per pa-sec-m2) 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 oors, 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 8.
If your home does not meet all of the three

criteria above, proceed to Determining Fresh­Air Flow For Heater Location, page 7.

AIR FOR COMBUSTION AND VENTILATION

Continued

Conned and Unconned Space

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/hr (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/hr (4.8 m3 per kw) of the ag-

gregate input rating of all appliances installed
in that space. Rooms communicating 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 between them.

DETERMINING FRESH-AIR FLOW
FOR HEATER LOCATION

Determining if You Have a Conned or
Unconned Space

Use this work sheet to determine if you have

a conned or unconned space.

Space: Includes the room in which you will install

replace 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. 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: 2560 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.

Direct-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 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 above 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 additional fresh air. Your
options are as follows:

A. Rework worksheet, adding the space of an

adjoining 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 8.

B. Vent room directly to the outdoors. See

Ventilation Air From Outdoors, page 8.

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

Hr size makes room unconned.

If the actual Btu/Hr used is less than the maxi-

mum Btu/Hr the space can support, the space is
an unconned space. You will need no additional

fresh air ventilation.

Ventilation Air From Outdoors

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, 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.

the International Fuel Gas Code,
or applicable local codes.

VENTILATION AIR

Ventilation Air From Inside Building

This fresh air would come from an adjoining

unconned space. When ventilating to an
adjoining 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).

INSTALLING HEATER BASE
ASSEMBLY

WARNING: You must secure

this heater to replace oor. If

not, heater will move when you
adjust controls. Moving heater

WARNING: If installing in a

sunken replace, special care

is needed. You must raise the

replace oor to allow access to

heater control panel. This will in-

sure adequate air ow and guard

against sooting and controls be-

ing damaged. Raise replace oor

with noncombustible material.
Make sure material is secure.

CAUTION: Do not pick up

heater base assembly by burn­ers. This could damage heater.

Only handle base assembly by

grates.

IMPORTANT: Make sure the heater burners
are level.

Installation Items Needed

• hardware package (provided with heater)

• approved exible gas hose and ttings

(provided) (if allowed by local codes)

• sealant (resistant to propane/LP gas, not

provided)

• electric drill with 3/16” masonry drill bit

1. Apply pipe joint sealant lightly to male

threads of the 1/2 NPT side of gas tting

elbow (provided) and connect to inlet

side of gas control. Remove gas tting
from exible gas hose (provided) before

connecting to elbow (see Figure 10).

NOTICE: Surface temperatures

of adjacent walls and mantels be­come hot during operation. Walls

and mantels above the rebox

may become hot to the touch.
If installed properly, these tem­peratures meet the requirement
of the national product standard.
Follow all minimum clearances
shown in this manual.

NOTICE: If your installation does
not meet the minimum clear­ances shown, you must do one
of the following:

• operate the logs only with the
ue damper open

• raise the mantel to an accept-

able height

• remove the mantel

FLOOR CLEARANCES

A. If installing appliance on the oor level,

you must maintain the minimum distance
of 14" to combustibles (see Figure 8).

B. If combustible materials are less than

14" to the replace, you must install ap­pliance at least 5" above the top surface

of combustible ooring including tile and

carpet.(see Figure 9).

2. Position heater base assembly in re­place.

3. Mark screw locations through holes in
front panel of base (see Figure 11). If

installing in a brick-bottom replace, mark

screw locations in mortar joint of bricks.

4. Remove heater base from replace.

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

6. Attach base, through holes in back side pan­els of base, to replace oor using masonry

screws provided in hardware package (see
Figure 11).

7. Connect to gas supply. See Connecting
To Gas Supply.

CONNECTING TO GAS SUPPLY

WARNING: This appliance

requires a 3/8" NPT (National

Pipe Thread) inlet connection to

the pressure regulator.

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

CAUTION: Never connect
propane/LP replace directly

to the propane/LP supply. This

heater requires an external regu­lator (not supplied). Install the
external regulator between the

heater and propane/LP supply.

WARNING: Never connect

natural gas replace to private
(non-utility) gas wells. This

gas is commonly known as
wellhead gas.

Installation Items Needed

Before installing heater, make sure you have

the items listed below.

• external regulator (supplied by installer)

• piping (check local codes)

• sealant (resistant to propane/LP gas)

• equipment shutoff valve *

• test gauge connection *

• sediment trap

• tee joint

• pipe wrench

• approved exible gas line with gas con-

nector (if allowed by local codes) (not
provided)

* An equipment shutoff valve with 1/8" NPT
tap is an acceptable alternative to test gauge
connection. Purchase the optional equipment
shutoff valve from your dealer.

For propane/LP units, the installer must

supply an external regulator. The external
regulator will reduce incoming gas pressure.
You must reduce incoming gas pressure to
between 11" and 14" of water. If you do not re-

duce incoming 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. In­ternally-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 volume will occur.

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).

IMPORTANT: Install equipment shutoff valve
in an accessible location. The equipment
shutoff valve is for turning on or shutting off
the gas to the appliance.

Check your building codes for any special
requirements for locating equipment shutoff

valve to replaces.

Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could
result in clogged heater valves.

WARNING: Use pipe joint

sealant that is resistant to liquid

petroleum (LP) gas.

We recommend that you install a sediment
trap in supply line as shown in Figure 13.
Locate sediment trap where it is within reach
for cleaning. Install in piping system between
fuel supply and heater. Locate 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 installed wrong, heater may

not run properly.
