PRODUCT FEATURES
OPERATION
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. When used without the blower, the
replace requires no electricity making it ideal for
emergency backup heat. This heater is designed
for vent-free operation. It has been tested and ap-
proved to ANSI Z21.11.2 standard for unvented
heaters. State and local codes in some areas pro-
hibit the use of vent-free heaters.
SAFETY DEVICE
This replace has a pilot with an Oxygen Depletion
Sensing (ODS) safety shutoff system. The ODS/
pilot is a required feature for vent-free room heat-
ers. The ODS/pilot system shuts off the replace
if there is not enough fresh air.
PIEZO IGNITION SYSTEM
This replace has a piezo ignitor. This system
requires no matches, batteries or other sources to
light replace.
OPTIONAL REMOTE CONTROL UNITS
There are four optional remote controls that can be
purchased separately for this log heater:
• wall switch
• wall thermostat
• hand-held ON/OFF remote
• hand-held thermostat remote
See Accessories, page 38.
OPTIONAL BLOWER ASSEMBLY
This replace accepts an optional blower assembly
(not included). The GA3700T Series blower oper-
ates thermostatically and features a variable speed
control. The GA3700 Series blower operates man-
ually and also features a variable speed control.
The blower circulates heated air from the replace
into the room. See Accessories, page 38.

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.
www.desatech.com 113109-01C6
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.
PROVIDING ADEQUATE
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.

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
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
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
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) = 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.

113109-01C 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 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 uncon-
ned 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 38.
www.desatech.com 113109-01C14
We recommend that you install a sediment trap in
supply line as shown in Figure 22. 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.
INSTALLATION
Continued
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 21. Pointing the vent down
protects it from freezing rain or sleet.
CAUTION: Use only new,
-
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 22).
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 replace valves. Never use sealant on
are threads.
