Match Heating and Cooling Capacity to Your Project
with These Four Dynaline™3 Models:
Model DL3-0712, with 7600 BTU/h cooling and 12,000 BTU/h gas heating
input, is ideal for small rooms or other applications that require zone
comfort control.
Model DL3-0912, with 9500 BTU/h cooling and 12,000 BTU/h gas heating
input, is ideal for hotels, motels, schools and nursing homes, or other
applications requiring zone comfort control.
Model DL3-1220 is for areas, such as, apartments and offices, with
11,500 BTU/h cooling and 18,000 BTU/h heating input.
Model DL3-1622 is for larger areas, such as, multi-family housing units, with
15,000 BTU/h cooling and 20,000 BTU/h heating input.
Economical Gas Heat
The unique Suburban Dynaline 3 provides high-efficiency gas heat in a zone
control heating and cooling unit. Clean gas heat is without equal for
economy and comfort. There is none of the “indoor wind chill”
that a heat pump creates. Compressor noise during the heating cycle is
eliminated, too. And, because Dynaline 3’s air discharge is much warmer
than a heat pump’s discharge, indoor temperatures reach a comfort level
much faster. The compressor operates only during the cooling cycle unlike
noisy heat pumps, thus extending the life of the compressor.
Savings for Builders
Dynaline 3’s space-saving, self-contained design eliminates most needs for
ductwork, water pipes, water towers, high-capacity standby generators and
rooftop equipment rooms. Dynaline 3 also frees architects and engineers
from the design constraints of central systems.
Safe
Dynaline 3’s sealed combustion furnace draws outside air through the heat
exchanger under negative pressure, and vents the products of combustion
directly to the outside atmosphere. Solid-state, electronic, hot surface
ignition (HSI) with no open flame is the modern alternative to pilot lights.
HSI increases energy conservation while ensuring safety.
Easy to Install and Service
Gas (LP or Natural) connections may be inside or outside the room.
Dynaline 3’s standard 42" x 16" wall sleeve makes it the right choice
for new construction or replacement applications. There is no need to
redesign an existing wall opening – just remove the old unit/sleeve and
replace with Dynaline 3.
Dynaline 3 combines a self-diagnostic control system, with a slide-out
chassis and removable electrostatic air filter (constructed of washable media)
for enhanced serviceability and easy maintenance.
INTRODUCTION
Dynaline™3 Packaged Terminal
Air Conditioner (PTAC) combines
the conventional features of
compact zone control systems with
the benefits of economical gas
heating. It provides year-round
comfort control for hotels, motels,
apartments, dormitories, shops,
nursing homes, assisted living
centers, satellite offices, room
additions and other applications
that require economical heating
and cooling. Specify Dynaline 3 for
new construction, or as the best
replacement for electric resistance
or heat pump units.
Each Dynaline 3 chassis has
individual controls – ideal for rooms
not occupied during vacancies,
holidays, weekends or nights.
Built-in, digital, touch pad heating
& cooling thermostat and fan
controls are standard, plus all units
have the flexibility to convert to a
wall thermostat control, or
interface into an energy
management system.
The greater the number of annual
heating degree days for a particular
locale, the more money Dynaline 3
can save in operating costs.
The Surburban Difference
Suburban developed the first gas-fired package terminal air conditioner (PTAC) in 1985.
Now in its third generation design, Suburban is a leading supplier to the senior housing
industry as well as other small commercial markets.

The Suburban Dynaline™3 is a Packaged Terminal Air Conditioner
(PTAC) that combines economical gas heating and high-efficiency
electric cooling in one compact unit for zone temperature room-by-
room control. By comparing the operating costs of Dynaline 3 to
heat pumps or electric resistance heat, a savings of hundreds of dol-
lars per room every year can be achieved.
The Dynaline
™3 Difference
* Bin Hours are the number of hours of operation per year at the mid-point temperature specific to a geographical
location. The BIN hours are derived from historical weather data.
For example, at a location with 7,023 heating BIN hours,
such as Syracuse, NY, with a 2º design temperature, the cost to
heat with Dynaline 3 can save 80% in utility costs compared to
electric resistance. When compared to heat pumps, Dynaline 3
can save 66%. For a building with 60 PTACs, Dynaline 3 can
save over $77,000 in utility costs in one year!

FRAMING In the United States and Canada, the installation must conform with local
codes. In the absence of local codes, US installations must conform with
the current National Fuel Gas Code ANSI Z223.1 and with the National
Electrical Code ANSI/NFPA No. 70, and Canadian installations must
conform with the current CANI-B149 installation code.
After selecting a location, inspect the wall and floor areas to determine
that there are no hidden electrical wires, piping, tubing, ducts, girders,
wall studs, etc., that might interfere with the proper installation and safe
operation of the unit and gas supply.
Dynaline™3 is designed to be installed through an exterior wall from
1" to 14-1/2" thick. To accommodate the unit’s dimensions (see Figure 5),
the wall opening must be framed as shown in Figures 6 & 7. For walls
thicker than 14-1/2", consult factory regarding available extended length
wall sleeves. The maximum wall thickness for rear gas hook-up is 12-5/8".
NOTE: Use conventional construction methods to frame the opening.
Do not use the wall sleeve as a lintel.

1. Unfold the sides of the wall sleeve and assemble the top, so that the
sides wedge between the top flange and the retaining angle. (See
Figure 8.) Apply 4 screws provided to secure top to the sides.
2. Cut an opening in the outside wall and frame to minimum opening.
(See Figures 6 & 7.)
3. Install wall sleeve into framed opening. Be sure that the bottom of wall
sleeve is resting firmly on the bottom framing member since the weight
of the unit rests solely on the bottom of the wall sleeve. Failure to
support the bottom of the wall sleeve could pull the sides away and
result in water leakage on the floor.
4. Secure the wall sleeve to the wall as shown in Figures 9 & 10. Be sure
wall sleeve has a 1/4" slope to the outside. Do not slope toward front!
To avoid water damage to the wall, do not put holes through the
bottom of the wall sleeve.
NOTE: If the unit is to be mounted flush with the exterior wall, wall
sleeve must protrude beyond the finished exterior wall a minimum of 1/4".
If rear gas connection, sleeve must extend beyond the finished exterior wall
surface 1-5/8”. (See Figures 9, 10, & 11.)
5. Trim around the wall sleeve with moulding or other suitable material.
(See Figures 9, 10, & 11.)
6. Install the grille with louvers angled in the downward position, as
shown in Figures 9, 10 & 11.
NOTE: Outside rear grille must be installed prior to installing chassis.
NOTE: Do not discard packing inside carton. It may be used as a
temporary cover for weather and construction protection. To cover the wall
sleeve opening, cut cardboard insert along the perforated line, fold and place
in rear of sleeve.

INSTALLING
THE CHASSIS
1. Slide chassis squarely into wall sleeve from inside and secure with four
(4) screws into flange on wall sleeve to ensure proper security.
2. Connect gas and electrical supply. (See pages 13, 14 and 20.)
3. Remote thermostat: Dynaline™3 chassis are supplied for standard
built-in control. To convert the standard chassis to function with remote
thermostat, connect the thermostat wiring (according to thermostat
manufacturer’s instructions) to the terminal block located on the
module board. Move the dip switch #1 on the module board to the
“ON” position. (See Figure 12.) Unit is capable of operating set-back
(5-wire) thermostat.
NOTE: Connecting remote thermostat overrides the built-in thermostat
and no digital read out will be displayed on the control panel. There is no
need to disconnect the chassis’ built-in thermostat.
4. To lock out the A/C compressor when the chassis is powered by
an emergency standby power generator, 24-volt lead wires from the
transformer (NOTE: Field supplied transformer to be powered by the
standby generator) must be connected to the 1/4" spade terminals on
the module board. (See Figure 27 for ladder diagram of typical standby
generator electric service.)
5. Install cabinet front.

Dynaline™3 chassis are factory equipped with a 3/8" NPT gas connection
located at the bottom left front corner. Gas piping used to make the gas
connection to the unit must be purchased locally. The size of the pipe should be
computed according to type of gas and length of run. (See Table 5 .) See Figure
13 for location of gas connection on the chassis when installed into
the wall sleeve.
Table 5 gives a reasonably accurate size for the gas service line. The quantities in
the table are for cubic feet per hour. To convert BTU capacity to cubic feet, divide
total BTU load by the BTU value of the gas being used. The table is for Natural
gas only. To convert to Propane gas, multiply by .633.
The pressure drop caused by other gas appliances being served must be
considered. If the new line is a take-off from an existing line to another
appliance, pressure drop computation with the table must include the
demand of the other appliance.

of 0.3 inches and specific gravity
of 0.60 inches.
All units are equipped with a valve having a built-in regulator. For units
burning Natural gas, the regulator is preset at 3.5" W.C. pressure. For units
burning LP gas, the regulator is preset at 10.5" W.C. pressure.
It is recommended that a shut-off valve be installed in the gas line to
the unit, and that a ground joint union also be installed.
NOTE: Manual shut-off valve to be supplied by installer.
A condensate trap should also be installed in the gas supply line as
close to the unit as possible.
To occasionally monitor the gas
supply pressure to the unit, install a
1/8" NPT plug tap for test gauge
connection immediately upstream
of the gas supply connection to the
unit. The unit must be disconnected
from the gas supply piping system
during any pressure testing of the
gas supply system at test pressures
equal to or greater than 1/2 PSIG.

AIR TO AN
ADJOINING ROOM.
• Rectangular Front
• Air Discharge Package
The optional air discharge package allows heating and cooling of an
adjoining room. (Not for use with 0712 Model.) The adaptor is
preassembled for air discharge to the right but can easily be converted
for discharge to the left. The adaptor is 43-1/4" long with female
connection. The extension is 43-1/4" long with 1" male tapered flange.
If you wish to discharge the air to the left, remove the end cover from
the left end of the adaptor and secure it to the right end. Next, turn it
around so the flow of air will be directed toward the front. The grille on the
adaptor need not be removed. Air apportionment can range from
30% to 70% for the primary room and 70% to 30% for the secondary room.
(See Table 6.)
Discharge air is dependent on Dynaline 3 model selected, mode of
operation (heat or cool), and length of total air discharge application.
When additional length is required, a connector is used in conjunction with
the air discharge package. Up to two connectors can be placed
between the adaptor and the extension (DL3-1220 or DL3-1622 only).
Suburban recommends that chassis with air discharge packages be
controlled via remote control thermostats.

1. Mount adaptor brackets to the wall as illustrated.
Installer to provide screws. (See Figure 17.)
2. Slide collar into position under the adaptor and secure
with the two (2) screws provided. (See Figure 16.)
3. If the required air flow direction is to the left, remove
the end cap and three (3) tinnermans from the left end
of the adaptor. Reinstall end cap and tinnermans to
the right end of the adaptor.
4. Remove the center section from the cabinet front
assembly. (See Figure 15.)If the center section is not
removed, you will be unable to open the cabinet
front once the collar and adaptor are installed.
Discard center section.
5. Remove the discharge air grille from the unit.
Retain the two (2) screws.
6. Place the adaptor and collar assembly into position
on the unit. Make sure the adaptor is resting on the
adaptor brackets – adjust brackets as needed!
7. Locate the hole in the adaptor bracket and mark the
underside of the adaptor at each end.
8. Remove adaptor and collar assembly from unit. At the
two (2) locations marked on the adaptor in Step #7,
drill a 7/64"-diameter hole (2 places).
9. Install adaptor and collar assembly on unit as
illustrated and secure with the two (2) screws retained
in Step #5. Also, secure the adaptor to the adaptor
brackets with the screws provided.
10. Install the extension (DL3-0912) or the connector(s)
and extension (DL3-1220 or DL3-1622 only) as
required. Installer must provide wall support brackets
for the connectors and extension.
11. Air Delivery: The air delivery baffle, located under the
discharge air grille in the adaptor, is factory positioned
to provide a 50/50 distribution of air into each zone.
By removing the baffle and cutting along the scored
line, 60% of the conditioned air will flow in the
primary zone. Removing the baffle results in a 70/30
split. (On model DL3-1622 you must remove the
baffle). For best results unit should be run on Hi only
when using discharge package.
