Early signs
of carbon monoxide poisoning resemble the
u, with headaches, dizziness or nausea. If
you have these signs, the heater may not
be working properly.
Have heater serviced. Some people are
more affected by carbon monoxide than oth-
ers. These include pregnant women, people
with heart or lung disease or anemia, those
under the inuence of alcohol and those at
high altitudes.
Natural and
propane/LP gases are odorless. An odor-
making agent is added to the gas. The odor
helps you detect a gas leak. However, the
odor added to the gas can fade. Gas may be
present even though no odor exists.
Make certain you read and understand all
warnings. Keep this manual for reference. It
is your guide to safe and proper operation of
this heater.

10. To prevent the creation of soot, follow the
instructions in Cleaning and Maintenance,
page 23.
11. Before using furniture polish, wax, carpet
cleaner or similar products, turn heater off. If
heated, the vapors from these products may
create a white powder residue within burner
box or on adjacent walls or furniture.
12. This heater needs fresh, outside air ven-
tilation to run properly. This heater has an
Oxygen Depletion Sensing (ODS) safety
shutoff system. The ODS shuts down the
heater if not enough fresh air is available.
See Air for Combustion and Ventilation,
page 6. If heater keeps shutting off, see
Troubleshooting, page 24.

• where ammable liquids or vapors are
used or stored
• under dusty conditions
14. Do not use this heater to cook food or burn
paper or other objects.
15. Do not use heater if any part has been ex-
posed to or under water. Immediately call
a qualied service technician to inspect
the room heater and to replace any part
of the control system and any gas control
which has been under water.
16. Do not operate heater if any log is broken.
Do not operate heater if a log is chipped
(dime-sized or larger).
17. Turn heater off and let cool before ser-
vicing, installing or repairing. Make sure
the remote selector switch is in the OFF
position. Only a qualied service person
should install, service or repair heater.
18. Make sure the remote selector switch is
in the OFF position when you are away
from home for long periods of time.
19. This heater must not be connected to any
external electrical source.

Ventilation Air From Outdoors
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 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 unconned 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 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.
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 door-
less 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)
-
National Fuel Gas Code, ANSI
Z223.1/NFPA54,International
Fuel Gas Code,-
-
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
efcient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning ap-
pliances 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, Air for
Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 6 through 8 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 ventilation. However, in buildings of un-
usually tight construction, you must provide
additional fresh air.
www.desatech.com
123741-01C 7
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
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 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 additional fresh air. Your options
are as follows:
A. Rework worksheet, adding the space of an
adjoining 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
Ventilation Air From Outdoors, page 8.
40,000
39,000
79,000
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 maxi-
mum Btu/Hr the space can support, the space is
an unconned space. You will need no additional
fresh air ventilation.
-
National Fuel
Gas Code,ANSI Z223.1/NFPA54,
International Fuel Gas Code,
This fresh air would come from an adjoining
unconned space. When ventilating to an
adjoining unconned 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

Provide extra fresh air by using ventilation grills
or ducts. You must provide two permanent open-
ings: 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 thermo-
stat-controlled power vent. Heated air entering
the attic will activate the power vent.

IMPORTANT:Vent-free heaters add moisture
to the air. Although this is benecial, installing
heater in rooms without enough ventilation
air may cause mildew to form from too much
moisture. See Air for Combustion and Ventila-
tion, page 6.
Use the correct gas type (natural or propane/
LP) for your unit. If your gas supply is not cor-
rect, do not install heater. Call dealer where

structed of noncombustible material.
Instal-
lation 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 you choose to use your heater as a man-
ually-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.
6' to 15' 39 sq. inches
15' to 30' 29 sq. inches
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
29). This will insure vented operation (see Fig-
ure 10). The damper clamp will keep damper
open. Installation instructions are included
with clamp accessory.
See chart below for minimum permanent ue
opening you must provide. Attach damper
clamp so the minimum permanent ue open-
ing will be maintained at all times.

Before installing heater, make sure you have
the items listed below.
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
* A CSA design-certied equipment shutoff
valve with 1/8" NPT tap is an acceptable al-
ternative to test gauge connection. Purchase
the optional CSA design-certied 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.
-
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 14, page 15).
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.

We recommend that you install a sediment
trap in supply line as shown in Figure 14.
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 from going into heater
controls. If sediment trap is not installed or is
installed wrong, heater may not run properly.

Con-
necting to Gas Supply
1. Disconnect appliance with its appliance
main gas valve (control valve) and equip-
ment shutoff valve from gas supply piping
system. Pressures in excess of 1/2 psig
will damage heater regulator.
2. Cap off open end of gas pipe where equip-
ment shutoff valve was connected.
3. Pressurize supply piping system by either
opening propane/LP supply tank valve
for propane/LP gas or opening main gas
valve located on or near gas meter for
natural gas or using compressed air.
4. Check all joints of gas supply piping sys-
tem. Apply noncorrosive leak detection
uid to gas joints. Bubbles forming show
a leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment shutoff
valve to gas supply. Check reconnected
ttings for leaks.
1. Close equipment shutoff valve (see Fig-
ure 15).
