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 fuel-burning
appliances in your home.
Today’s homes are built more energy efficient
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
efficient, 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, fireplaces, 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 classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined 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.
6
Unusually tight construction is defined
as construction where:
a. walls and ceilings exposed to the outside atmosphere have a continuous
water vapor retarder with a rating of one
perm (6x10-11 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 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 FreshAir Flow for Heater Location.
Confined and Unconfined Space
National Fuel Gas Code, ANSI Z223.1/NFPA
54 defines a confined 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
unconfined 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 unconfined space.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.
DETERMINING FRESH-AIR FLOW
FOR Heater LOCATION
Determining if You Have a Confined or
Unconfined Space
Use this work sheet to determine if you have
a confined or unconfined space.
Space: Includes the room in which you will install
fireplace plus any adjoining rooms with doorless 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)
www.desatech.com
113097-01L
AIR FOR COMBUSTION AND VENTILATION
Continued
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 = (Maximum 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 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:
40,000 Btu/Hr
Gas water heater
___________
39,000 Btu/Hr
Vent-free fireplace
+__________
79,000 Btu/Hr
Total
=__________
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 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 confined 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
unconfined 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.
C. Install a lower Btu/Hr fireplace, if lower Btu/
Hr size makes room unconfined.
113097-01L
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is
an unconfined 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 unconfined space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the floor 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, Air for Combustion and

INSTALLING DAMPER CLAMP
ACCESSORY FOR VENTED
OPERATION
Note: When used as a vented heater, appliance must be installed only in a solid-fuel
burning fireplace with a working flue and constructed of noncombustible material.
For Massachusetts Residents Only: Installation of this gas log set as a vented appliance
in the Commonwealth 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 fireplace does not meet the clearance
to combustibles requirements for ventfree operation.
2. State or local codes do not permit ventfree operation.
3. You prefer vented operation.
If reasons number 1 or 2 above apply to you,
you must permanently open chimney flue
damper. You must install the damper clamp
accessory (to order, see Accessories, page
31). This will insure vented operation (see Figure 10). The damper clamp will keep damper
open. Installation instructions are included
with clamp accessory.
See chart for minimum permanent flue opening you must provide. Attach damper clamp
so the minimum permanent flue opening will
be maintained at all times.

INSTALLING HEATER BASE
ASSEMBLY
CAUTION: Do not remove the
data plates attached to the heater
base assembly. The data plates
contain important warranty and
safety information.
WARNING: You must secure
this heater to fireplace floor. If
not, heater will move when you
adjust controls. Moving heater
may cause a gas leak.
WARNING: If installing in a
sunken fireplace, special care
is needed. You must raise the
fireplace floor to allow access
to heater control panel. This
will insure adequate air flow
and guard against sooting and
controls being damaged. Raise
fireplace floor with noncombustible material. Make sure material
is secure.
CAUTION: Do not pick up
heater base assembly by the
burner. 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. For thermostat models, avoid
damage to thermostat bulb. Avoid nicks or
sharp bends in thermostat bulb wire. Keep
thermostat bulb in mounting bracket until
ready to mount base to floor. See Optional
Positioning Of Thermostat Sensing Bulb,
page 29.
Installation Items Needed

CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 1/2" NPT (National
Pipe Thread) inlet connection to
the pressure regulator.
WARNING: A qualified service person must connect heater
to gas supply. Follow all local
codes.

INSTALLATION
Continued
CAUTION: Never connect
heater directly to the propane/LP
supply. This heater requires an
external regulator (not supplied).
Install the external regulator between the heater and propane/
LP supply.
CAUTION: Use only new, black
iron or steel pipe. Internally-tinned
copper tubing may be used in
certain areas. Check your local
codes. Use pipe of 1/2" diameter
or greater to allow proper gas volume to heater. If pipe is too small,
undue loss of volume will occur.
WARNING: Never connect
natural gas fireplace to private
(non-utility) gas wells. This
gas is commonly known as
wellhead gas.
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 15, page 15).
IMPORTANT: Install equipment 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 fireplaces.
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.
Installation Items Needed
Before installing heater, make sure you have
the items listed below.
• external regulator (supplied by installer)
• 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-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase
the optional CSA design-certified equipment
shutoff valve from your dealer. See Accessories, page 31.
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 pressure, heater regulator
damage could occur. Install external regulator
with the vent pointing down as shown in Figure
14. Pointing the vent down protects it from
freezing rain or sleet.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
We recommend that you install a sediment trap
in supply line as shown in Figure 15, page 15.
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 contaminants. This keeps them from going into heater
controls. If sediment trap is not installed or is
installed wrong, heater may not run properly.

Note: The pilot flame on natural gas units will
have a slight curve, but flame should be blue
and have no yellow or orange color.
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes
in the fitting at the entrance to the burner.
These holes may become blocked with dust,
lint or pet hair. Periodically inspect these holes
for any blockage and clean as necessary.
Blocked air holes will create soot.
Main Burner
Periodically inspect all burner flame holes with
the heater running. All slotted burner flame
holes should be open with yellow flame present. All round burner flame holes should be
open with a small blue flame present. Some
burner flame holes may become blocked by
debris or rust, with no flame present. If so,
turn off heater and let cool. Remove blockage.
Blocked burner flame holes will create soot.
Cleaning and Maintenance
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep
control areas, burner and circulating air passageways of heater
clean. Inspect these areas of
heater before each use. Have
heater inspected yearly by a
qualified service person. Heater
may need more frequent cleaning due to excessive lint from
carpeting, bedding material, pet
hair, etc.
WARNING: Failure to keep
the primary air opening(s) of
the burner(s) clean may result in
sooting and property damage.
113097-01L
Burner Injector Holder and
Pilot Air Inlet Hole
The primary air inlet holes allow the proper
amount of air to mix with the gas. This provides a clean burning flame. Keep these
holes clear of dust, dirt, lint and pet hair.
Clean these air inlet holes prior to each
heating season. Blocked air holes will create
soot. We recommend that you clean the unit
every three months during operation and
have heater inspected yearly by a qualified
service person.
We also recommend that you keep the burner
tube and pilot assembly clean and free of dust
and dirt. To clean these parts we recommend
using compressed air no greater than 30 PSI.
Your local computer store, hardware store or
home center may carry compressed air in a
can. If using compressed air in a can, please
follow the directions on the can. If you don’t
follow directions on the can, you could damage the pilot assembly.

1. Shut off unit, including pilot. Allow unit to
cool for at least thirty minutes.
2. Inspect burner, pilot and primary air inlet
holes on injector holder for dust and dirt
(see Figure 35).
3. Blow air through the ports/slots and holes
in the burner.
4. Check the injector holder located at the
end of the burner tube again. Remove
any large particles of dust, dirt, lint or pet
hair with a soft cloth or vacuum cleaner
nozzle.
5. Blow air into the primary air holes on the
injector holder.
6. In case any large clumps of dust have now
been pushed into the burner repeat steps
3 and 4.
Clean pilot assembly also. A yellow tip on the
pilot flame indicates dust and dirt in the pilot
assembly. There is a small pilot air inlet hole
about 2" from where the pilot flame comes out
of the pilot assembly (see Figure 36). With the
unit off, lightly blow air through the air inlet
hole. You may blow through a drinking straw
if compressed air is not available.

Optional Positioning of Thermostat Sensing Bulb
For Masonry and Factorybuilt Metal Fireplace
If your log set cycles to pilot, but the room
temperature drops to a lower than ideal
comfort level before the log set comes back
on, you may want to reposition the thermostat
sensing bulb.
The thermostat sensing bulb is located near the
gas valve assembly on the mounting bracket.
This location allows the thermostat to keep the
room temperature at an ideal comfort level for
most fireplace applications. For positioning
the thermostat sensing bulb elsewhere, an
adhesive-backed mounting clip is available.
Tools needed: 1/4" hex driver or socket
1. Remove logs. Locate the gas valve assembly and thermostat sensing bulb (see
Figure 37).
2. With 1/4" hex driver or socket, loosen the
thermostat screw. Carefully slide the thermostat sensing bulb out of the retaining
clamp (see Figure 39).
Note: Do not remove the screw. Make sure
you tighten the screw after removing the
thermostat sensing bulb.
IMPORTANT: Do not force or bend the
thermostat sensing bulb or capillary.
3. The thermostat sensing bulb may be located
to the lower right front side of fireplace.
Determine location of sensing bulb, but do
not mount sensing bulb until step 4. If you
have a masonry fireplace, see Figure 40
for location. If you have a factory-built
metal fireplace, see Figure 41 for location.
If your fireplace has glass doors, position
sensing bulb directly behind door gap on
right bottom side (see Figure 42).
4. The mounting clip must be a minimum
of 3" from bottom of fireplace to prevent
crimping of capillary. Once you have
decided on a location, clean the area
