PRODUCT FEATURES
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. This heater may also be
operated as a vented decorative (ANSI Z21.60)
product by opening ue damper (non-thermostat
models only).
This heater has a pilot with an Oxygen Deple-
tion 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.
This heater has a piezo ignitor. This system re-
quires no matches, batteries or other sources to
light heater.

Today’s homes are built more energy efcient
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.

The following are excerpts from National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Section 5.3,
Air for Combustion and Ventilation.
All spaces in homes fall into one of the three fol-
lowing ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 5 through 7 will help
you classify your space and provide adequate
ventilation.

may provide enough fresh air for combustion and
ventilation. However, in buildings of unusually

Determining
Fresh-Air Flow For Heater Location
The National Fuel Gas Code, ANSI Z223.1/NFPA
54 denes a conned space as a space whose vol-
ume is less than 50 cubic feet per 1,000 Btu per hour
(4.8 m
3
per kw) of the aggregate input rating of all
appliances installed in that space and an unconned
space as a space whose volume is not less than 50
cubic feet per 1,000 Btu per hour (4.8 m
3
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 unconned space.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation grills
between them.
DETERMINING FRESH-AIR FLOW
FOR HEATER LOCATION
Use this work sheet to determine if you have a
conned or unconned space.
Includes the room in which you will install
heater plus any adjoining rooms with doorless pas-
sageways 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. Di-
rect-vent draws combustion air from the outdoors
and vents to the outdoors.
www.desatech.com
111161-01H 7
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 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 example is a conned space
because the actual Btu/Hr used is more than the maxi-
mum 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 adjoin-
ing room. If the extra space provides an unconned
space, remove door to adjoining room or add
ventilation grills between rooms. See Ventilation
Air From Inside Building.
B. Vent room directly to the outdoors. See Ventila-
tion Air From Outdoors.
C. Install a lower Btu/Hr replace, if lower Btu/Hr
size makes room unconned.
If the actual Btu/Hr used is less than the maximum
Btu/Hr the space can support, the space is an un-
conned space. You will need no additional fresh
air ventilation.

unconned space, you must provide two perma-
nent 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/NFPA 54, Section 5.3, Air for

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.
If you choose to use your heater as a manually-
controlled model (no remote control installed),
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 vent-free
operation.
3. You prefer vented operation.
If reasons number 1 or 2 above 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, page 12). The damper
clamp will keep damper open. Installation instruc-
tions are included with clamp accessory.
See chart below for minimum permanent ue
opening you must provide. Attach damper clamp
so the minimum permanent ue opening will be
