heaters.
CAUTION
The correct shutdown procedure must be followed to prevent damage to the burner assembly.
Figure 4. Control panel
4.1 Duct Selection
4.1.1 General Guidelines
The ES700B heater is an outdoor heater designed to safely heat enclosures using flexible duct
connections. For efficient operation, keep duct lengths as short as possible. Excessive duct lengths will
reduce air flow in the heat exchanger and cause the burner to cycle to control the outlet temperature.
Excessive burner cycling shortens the life of the heat exchanger and should be avoided. Burner cycling
can be controlled by reducing duct length, increasing the duct diameter, or adjusting the burn rate (see
Section 4.9).
An inlet duct is not required for normal operation. It can be used to circulate warm air back from an
enclosure for re-heating.
4.1.2 Duct Sizes
Minimum inlet duct size ............................................................20”
Minimum outlet duct size ..........................................................12”

Operation MANUAL - ES700B
Rev November 2019
Copyright © 2019 Equipment Source Inc.
Page 14 of 30
4.2 Recommended Fuels and Fueling Instructions
CAUTION
Do not overfill tanks. Tanks should be filled to only 90% of the full volume to allow thermal expansion.
Use ULSD No.1 or ULSD No.2 for all heater models except the ES700B-ED. For continuous duty
operation, a daily refilling schedule should be established.
4.2.1 ES700B-ED (aux tank equipped machine) Refueling
Instructions
The ES700B-ED model has an auxiliary fuel tank for the engine. This allows locally approved heating oil
to be used in the burner and ULSD fuel for the engine. Observe machine placards for fuel types and
placement.
CAUTION
ES700B-ED Model: Always refill the auxiliary ULSD tank when filling the main heating oil tank to prevent
engine failure while the heater is operating. Premature generator shutdown can damage the burner.
4.3 Access and Clearance
Ensure all sides of the heater are easily accessible. Heater should be more than 3ft [1m] from any
structure. Heater is correctly placed when the operator can walk around the perimeter of the heater
with minimal obstruction. Check for placement and access of fire extinguisher.
4.4 Leveling
Ensure heater is placed on firm ground and wheels (if equipped) are chocked. Heater should be close to
level across the width (±1°). The heaters should be slightly lower in the front to maximize fuel tank
capacity. For trailer mounted heaters, use the tongue jack to level the heater and then lower the tongue
jack 1 to 2 inches (2.5 to 5cm).
If the heater is placed on frozen ground or ice, frequently check the heater for shifting and
reposition/level as necessary.

4.5 Pre-Startup Checklist
Use the following checklist to determine whether the machine can be safely started and operated:
1. Heater is level and on stable ground (per Section 4.4)
2. Wheels are chocked
3. Exhaust vents are free of obstruction
4. 3ft [1m] clearance from permanent structures on all sides
5. Fire extinguisher is accessible
6. Water is drained from fuel filters
7. Engine oil and coolant levels normal
8. Fuel tank filled with recommended fuel type
9. Inlet and outlet ducts are free of obstruction
10.Machine safeguards are connected and functioning
4.6 Startup
Use the following checklist to start and operate the machine. Open the door labeled “Machine Controls”
to access all required controls.
1. Turn off the Master Disconnect Breaker and the Burner Control Switch
2. Turn the key switch to position I for 15 seconds
3. Turn the key switch to position II to engage starter
4. Let generator engine warm for at least 1 minute
5. Turn on Master Disconnect Breaker
6. Turn on Fan
7. Cycle the Burner Control Switch to provide heat as necessary
4.7 Monitoring and Operation
4.7.1 Daily Inspection
Listen for abnormal sounds
Check fluid levels
Observe burn quality (no smoke should be visible)
Check if level and secure
Check vents for icing or other obstructions
Check fire extinguisher access.
Observe recommended maintenance schedule
4.7.2 Adjusting Heat Output

Operation MANUAL - ES700B
Rev November 2019
Copyright © 2019 Equipment Source Inc.
Page 16 of 30
Connect an external thermostat (see wiring diagram) to control building heat.
Increase the outlet temperature by constricting the outlet airflow or changing the fan belt pulleys.
The outlet temperature is limited to 220F and undesirable burner cycling will occur if the ducts are
excessively restricted. Increasing the outlet temperature by reducing the air flow will never increase
the heat output.
Increase or decrease the outlet temperature and heat output by adjusting the firing rate (refer to
Section Adjusting the Firing Rate)
4.8 Shutdown
CAUTION
The following shutdown procedure must be observed to prevent damage to the burner.
Shutdown procedure:
1. Shutdown burner using the control switch
2. Let the generator and fan run for 5 minutes
3. Turn off fan
4. Turn off generator
4.9 Adjusting the Firing Rate
The firing rate can be adjusted by changing the nozzle size or adjusting the fuel pressure. Refer to the
instruction manual supplied for the Carlin 301CRD oil burner the following Nozzle Capacity Chart when
making adjustments to the firing rate and airflow. Changing the firing rate may require adjustments to
the air flow.
4.9.1 Standard Firing Rate
A new ES700B series heater comes equipped with a 3.5 GPH nozzle. The fuel pressure on a new machine
is tuned to 150 PSI resulting in a 4.3 GPH firing rate.
4.9.2 Maximum Firing Rate
Nozzles rated up to 4.5 GPH @ 100 PSI and pressures up to 150 PSI can be safely used if additional heat
is required or the outlet air temperature is low. Low outlet air temperature can also be increased by
constricting the airflow in the outlet ducts or changing the belt pulleys to reduce the fan speed.
4.9.3 When to Reduce the Firing Rate
The firing rate should be reduced if the burner cycles during normal operation as a result of excessive
outlet temperature. Excessive burner cycling will shorten the life of the heat exchanger. The firing rate
can be reduced by adjusting the fuel pressure or using a smaller nozzle. The minimum nozzle size is
3.0 GPH.
Consider shortening the duct length or increasing the size of the ducts before reducing the firing rate.

5.4.1 Belt tensioning and replacement
Belts tend to stretch and should be periodically checked for tension and wear. The belt is properly
tensioned when the belt defects approximately 3/16 in [5 mm] with moderate thumb pressure. Use the
belt tensioning screws on the motor mounting plate to adjust the belt tension.
Replace belts if cracking or fraying is observed. Abnormal belt wear or rapid wear rates may be the
result of pulley misalignment. Refer to the maintenance manual provided by the blower manufacture for
additional adjustment information.
5.4.2 Lubrication
Use a high quality lithium based grease conforming to NGLI Grade 2 to lubricate the billow block
bearings and motor bearings every 3000 hours of operation.
