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 from
theflames.Thisheaterisdesignedforvent-free
operation with flue damper closed. It has been
testedandapprovedtoANSIZ21.11.2standard
for unvented heaters. State and local codes
in some areas prohibit the use of vent-free
heaters. This heater may also be operated as
a vented decorative (ANSI Z21.60) product by
opening the flue damper.
SAFETY DEVICE
Thisheaterhasapilotwith an Oxygen Deple-
tionSensing(ODS)safetyshutoffsystem.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 igniter to light
heater fuel supply.
AIR FOR COMBUSTION AND VENTILATION
Today’shomes are built more energy efficient
thanever.New materials,increasedinsulation
and new construction methods help reduce
heat loss in homes. Homeowners apply
weather strip and caulk around windows and
doorstokeep the coldairout and thewarmair
in.Duringheatingmonths,homeowners 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 ap-
pliancesneedfreshairforpropercombustion
and ventilation.
Exhaust fans, some fireplaces, clothes dryers
and some fuel-burning appliances draw air
from the house to operate. You must provide
adequate fresh air for these appliances. This
will ensure proper venting of vented fuel-
burning appliances.
PROVIDING ADEQUATE
VENTILATION
Thefollowingareexcerptsfrom 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 classifications:
WARNING: This heater shall not
be installed in a room or space un-
less 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 ensure
properfresh air for thisand other fuel-
burning appliances in your home.
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on Pages 6-8 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 un-
usually tight construction, you must provide
additional fresh air.
Unusually tight construction is defined 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 floors, between wall-ceiling joints,
between wall panels, at penetrations
for plumbing, electrical and gas lines
and at other openings.
If your home meets all three criteria above,
you must provide additional fresh air. See
Ventilation Air From Outdoors, Page 8.
If your home does not meet all three crite-
ria above, proceed to Determining Fresh-
Air Flow For Heater Location, Page 7.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/
NFPA54 allows two methods for determining
whetherthespaceinwhich theheateris being

installedisconfined orunconfinedspace.The
standardmethoddefinesa confinedspaceas
a space whose volume is less than 50 cubic
feetper1,000 Btu/hr (4.8m3perkw)of theag-
gregateinputratingofallappliancesinstalled
in that space and an unconfined space as
a space whose volume is not less than 50
cubic feet per 1,000 Btu/hr (4.8 m3per kw) of
the aggregate input rating of all appliances
installedinthat space.Roomscommunicating
directlywiththe spaceinwhichthe appliances
areinstalled*,throughopenings not furnished
with doors, are considered a part of the un-
confined space.
Where the air infiltration rate of a structure is
known,theKnownAirInfiltrationRate Method
may be used. Follow The National Fuel Gas
Code, ANSI Z223.1/NFPA 54 to use this
method to determine if the space is confined
or unconfined.
* Adjoining rooms are communicating only if
therearedoorless passagewaysorventilation
grills between them.
DETERMINING FRESH-AIR FLOW
FOR HEATER LOCATION
Determining if You Have a Confined or
Unconfined Space Using the Standard
Method
Use this work sheet to determine if you have
a confined or unconfined space.
Space: Includesthe roomin whichyou willinstall
fireplace plus any adjoining rooms with door-
less passageways or ventilation grills between
the rooms.
1. Determine the volume of the space (length
x width x height).
LengthxWidth xHeight=__________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. (volumeofspace) x20
= 51,200 (maximum Btu/Hr the space can
support)
3. Add the Btu/Hr of all fuel burning appliances
in the space.
Vent-free fireplace __________Btu/Hr
Gas water heater* __________Btu/Hr
Gas furnace __________Btu/Hr
Vented gas heater __________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.
Example:
Gas water heater __________Btu/Hr
Vent-free fireplace + _________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 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 confined
space because the actual Btu/Hr used is more
than the maximum Btu/Hr the space can sup-
port. 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
anunconfined space,removedoortoadjoin-
ing 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 fireplace, if lower Btu/
Hr size makes room unconfined.
If the actual Btu/Hr used is less than the maxi-
mum Btu/Hr the space can support, the space is
anunconfined space.You willneed noadditional
fresh air ventilation.

proper gas volume to heater. If
pipe is too small, undue loss of
volume will occur.
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
reduceincominggas pressure,heaterregula-
tordamagecouldoccur.Installexternalregu-
lator with the vent pointing down as shown in
Figure 12. Pointing the vent down protects it
from freezing rain or sleet.
WARNING: Use pipe joint
sealantthatisresistanttoliquid
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 contami-
nants.This keeps them fromgoingintoheater
controls. If sediment trap is not installed or is
installed wrong, heater may not run properly.
CAUTION: Avoid damage to
regulator. Hold gas regulator
with wrench when connecting
it to gas piping and/or fittings.
