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.
State of Massachusetts: The installation
must be made by a licensed plumber or
gas tter in the Commonwealth of Mas-
sachusetts.
Sellers of unvented propane or natural
gas-red supplemental room heaters shall
provide to each purchaser a copy of 527
CMR 30 upon sale of the unit.
Vent-free gas products are prohibited for
bedroom and bathroom installation in the
Commonwealth of Massachusetts.
UNPACKING
CAUTION: Do not remove the
1. With utility knife, cut the carton all the way
around above the staples on the bottom tray.
Lift the carton off the heater. Remove packing.
Note: The hood is located in the packing on
the right hand side of the heater front. Lift the
heater off the bottom tray.
2. Locate two screws above top corners of the
replace screen. Remove and discard these
screws. Lift replace screen up and pull out to
remove.
3. Remove protective packaging applied to logs,
log base assembly, and replace.
4. Remove replace hood from carton insert.
5. Check all items for any shipping damage. If
damaged, promptly inform dealer where you
bought replace.
PRODUCT FEATURES
This vent-free replace 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 embers. When used without the
optional blower, the replace requires no electricity
making it ideal for emergency backup heat.

VENTILATION
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.
The air that leaks around doors and windows may
provide enough fresh air for combustion and ven-
tilation. However, in buildings of unusually tight
construction, you must provide additional fresh air.

If your home meets all of the three criteria
See Ventilation Air From Outdoors
If your home does not meet all of the three
The National Fuel Gas Code, ANSI Z223.1/
NFPA 54 denes a conned 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 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 m3 per kw) of the aggregate input rating of
all appliances installed in that space. Rooms com-
municating 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
Use this work sheet to determine if you have a
conned or unconned space.
Includes the room in which you will install
replace 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) = 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. Di-
rect-vent draws combustion air from the outdoors
and vents to the outdoors.
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.
www.desatech.com
119304-01A 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)
73,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the example is a conned space because
the actual Btu/Hr used is more than the maximum
Btu/Hr the space can support. You must provide ad-
ditional 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.

Installation Items Needed
Before installing replace, make sure you have
the items listed below.
• external regulator for propane/LP unit only
(supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap (optional)
• tee joint
• pipe wrench
• approved exible gas line with gas connector
(if allowed by local codes) (not provided)
* A CSA design-certied equipment shutoff valve
with 1/8" NPT tap is an acceptable alternative to
test gauge connection. Purchase the optional CSA
design-certied equipment shutoff valve from your
dealer. See Accessories, page 32.
www.desatech.com
119304-01A 13
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 reduce incoming gas pres-
sure, heater regulator damage could occur. Install
external regulator with the vent pointing down
as shown in Figure 17. Pointing the vent down
protects it from freezing rain or sleet.
-
-
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 replace (see Figure 18).
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 re-
quirements 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 re-
place valves. Never use sealant on are threads.

We recommend that you install a sediment trap in
supply line as shown in Figure 18. Locate sediment
trap where it is within reach for cleaning. Install in
piping system between fuel supply and replace.
Locate sediment trap where trapped matter is not
likely to freeze. A sediment trap traps moisture
and contaminants. This keeps them from going
into replace gas controls. If sediment trap is not
installed or is installed wrong, replace may not
run properly.

INSPECTING BURNERS
Check pilot ame pattern and burner ame pat-
terns often.
Figure 32 shows a correct pilot ame pattern.
Figure 33 shows an incorrect pilot ame pattern.
The incorrect pilot ame is not properly heating
the thermocouple. When the thermocouple cools,
the heater will shut down.
If pilot ame pattern is incorrect, as shown in
Figure 33
• turn heater off (see To Turn Off Gas to Appli-
ance, page 18)
• see Troubleshooting, page 23
Note: The pilot ame on natural gas units will
have a slight curve, but ame should be blue and
have no yellow or orange color.

Pilot Burner
Periodically inspect all burner ame holes with
the heater running. All slotted burner ame holes
should be open with yellow ame present. All
round burner ame holes should be open with a
small blue ame present. Some burner ame holes
may become blocked by debris or rust, with no
ame present. If so, turn off heater and let cool.
Remove blockage. Blocked burner ame holes
may create soot.
