PRODUCT FEATURES

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

realistic, dancing yellow ames. 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.

126838-01A 5

www.SuperiorFireplaces.US.com

SAFETY PILOT

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.

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 fuel­burning 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.
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.

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.

www.SuperiorFireplaces.US.com

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 (6x10

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
Fresh-Air Flow For Heater Location.

Conned Space 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 per hour (4.8 m3 per kw) of the ag-

gregate 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 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.

AIR FOR COMBUSTION AND VENTILATION

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.

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

See Ventilation Air From Inside Building.

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.

WARNING: If the area in which
the heater may be operated does
not meet the required volume for
indoor combustion air, combus­tion and ventilation air shall be
provided by one of the methods
described in the National Fuel

Gas Code, ANSI Z223.1/NFPA 54,

the International Fuel Gas Code,
or applicable local codes.

VENTILATION AIR

Ventilation Air From Inside Building

This fresh air would come from an adjoining

unconfined 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). Fol­low the National Fuel Gas Code ANSI Z223.1/

clearances between replace opening and

mantel shelf. If you do not meet the clearances

listed below, you will need a hood.

Determining Minimum Mantel Clearance

If you meet minimum clearance between
mantel shelf and top of replace opening, a

hood is not required (see Figure 6).

Determining Minimum Mantel Clearance

When Using a Hood

If minimum clearances in Figure 6, page 10, are
not met, you must have a hood. When using

a hood there are still certain minimum mantel

clearances required. Follow minimum clear­ances shown in Figure 7 when using hood.

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).

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:

INSTALLING DAMPER CLAMP
ACCESSORY FOR VENTED
OPERATION

Note: When used as a vented heater, ap­pliance must be installed only in a solid-fuel
burning replace with a working ue and con­structed of noncombustible material.

For Massachusetts Residents Only: Instal­lation of this vented gas log set in the Com-

monwealth of Massachusetts requires the
damper be permanently removed or welded

in the fully open position.

If your heater is a 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 replace does not meet the clearance

to combustibles requirements for vent-free
operation.

2. State or local codes do not permit vent­free operation.

3. You prefer vented operation.

INSTALLATION

Continued

If reasons number 1 or 2 apply to you,
you must permanently open chimney ue
damper. You must install the damper clamp
accessory (to order, see Accessories, page

34). This will insure vented operation (see Fig­ure 10). The damper clamp will keep damper

open. Installation instructions are included

with clamp accessory.

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

being damaged. Raise replace
oor with noncombustible mate-

rial. 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. If heater is not level, heater will not
work properly.
