NOTE:
Horsepower selections are based on system total static
pressure. One or more of the following must be added when
applicable. See pressure drops on page 6 for burner section
and optional inlet hood and V-bank sections.
SELECTION GUIDE
1. Determine the required amount of replacement air
(CFM) by computing the total amount of air being
exhausted. (Restaurants should be sized for 90% of
exhaust air to minimize food odors.)
A. Fresh Air Inlet Hood & Birdscreen
.— W.C.
B. Fresh Air Inlet Hood with Filters
— W.C.
2. Determine the total external static pressure by adding
the pressure drops through all accessories and ducts.
C. V-Bank Filter Section
— W.C.
F. Burner Section
— W.C.
3. Select unit size and motor horsepower from table.

2. Select burner required.
BTUH = SCFM x 1.32605 x 29.92 x 0.24 x 60 x Temperature Rise
.92 (460 + Temperature Rise + Inlet Temperature)
where
1.32605 = density of air handled by the blower
29.92 = barometric pressure at sea level
0.24 = specific heat of the air handled by the blower
60 = conversion for minutes to hour
0.92 = average ratio of net and gross heating values of common fuel
gases (92% sensible, 8% latent)

3. Values shown in above MBH Input Table are
based on -40° F Inlet Temperature. MBH
input shown on unit rating plate will be
corrected for actual air density.
4. Natural gas units are limited to 130° F
temperature rise, propane units are limited
to 100° F temperature rise.

Pre-Purge Timing
C000473
The standard unit is provided with a 10 second pre-purge timer which is good for all rooftop units without inlet duct work. If inlet duct is
attached to heater, ANSI requirements stipulate that the inlet duct must be purged four times prior to trial for ignition. to calculate the
maximum allowable inlet duct lenth, use:
Maximum Inlet Duct Length (feet) = Inlet Duct Velocity (FPM) / 24

Guide Specification – Mixing Dampers With
Return Air Flow Station
Unit(s) shall have outside air and return air
dampers with modulating actuator controlled
by AdaptAire DDC control system. The
AdaptAire DDC control system shall have
capability to digitally control the outside air
quantity from a nominal minimum of 20% to
100% with integrated gas valve control at all
room concentrations of CO2.
The return air inlet shall include a selfcalibrating flow measuring station with a
grid of velocity pressure probes with spacing
no greater than 12” over the entire face of
the return air opening and sampled every
two seconds. Samples will be added to a
twenty-five point rolling average and then
on to a second rolling average to provide
smooth, accurate data that is delivered to
the AdaptAire DDC control system every
two seconds. The DDC control system shall
be capable of electronically displaying the
return air/outside air ratio within 5%
accuracy at all damper positions.
26
The AdaptAire DDC control system shall be
capable of controlling mixing dampers in:
(Choose One)
Manual Mode: The “Manual” mode allows
manual positioning of the outside air (O.A.)
damper and return air (R.A.) damper by
changing the damper position setpoint.
Mixed Air Temperature Mode: The “Mixed
Air Temperature” mode shall provide
automatic control of the mixed air temperature by modulating the outside air (O.A.)
damper and return air (R.A.) damper to
maintain the mixed air temperature setpoint.
As the mixed air temperature increases
above the setpoint more outside air will be
introduced.
Building Pressure Mode: The “Building
Pressure” mode shall provide automatic
building pressure control by modulating the
outside air (O.A.) damper and return air
(R.A.) damper to maintain the indoor
building pressure setpoint. As the building
pressure decreases below the setpoint more
outside air will be introduced.

Sequence of Operation – Return Air Units
P000621
Signal from remote control I to AdaptAire
Controller D, sets operational parameters
for dampers B and C, and burner. Damper
operation can be manual, building pressure or mixed air temperature.
Return air dampers B, and outside air
dampers C, are interlocked to move
together. As one opens, the other closes.
As the return air dampers open, allowing
more return air to enter the unit, the outside air dampers move toward the closed
position, decreasing the amount of outside
air. Pressure sensor and flow station J,
senses change in return airflow and signals
AdaptAire Controller D.
Modulating gas valve H, regulates gas
supply in response to signal from AdaptAire
Controller D. AdaptAire Controller D, varies
signal based on input from room temperature sensor F, discharge temperature
sensor G, and airflow sensor J. Gas valve H
can provide approximately 4% to 100% of
rated burner capacity.
