WARNING
If unit fails to ignite or function properly;
disconnect fuel and power supplies and
contact authorized service personnel.
NOTE: If the blower does not turn on, check
the control braker (The “Power” indicator light
will confirm that the control braker is good) or
make sure the VFD is energized.
NOTE: Placing the Main switch in the “OFF”
position will automatically reset the heater if the
control is in a lock out condition. If the burner
still does not ignite, use the following sequence
of steps:
1. Make sure the gas pressure is adequate.
2. Check to make sure all manual valves are
open between the fuel source and the
burner.
3. Check to make sure the proper voltage is
supplied to the heater.
WARNING
A qualified electrician must make the
adjustments.
4. Check to be sure the air proving switch
sensor tubes are clear of any obstructions.
NOTE: Listen to hear the pilot solenoid valve
click. If the click is not heard,the solenoid valve
may not be opening and may be defective.
Sparking should also be present at the spark
igniter in the burner If the click is heard and
pressure is registered, move the main switch to
the “OFF” position and place the Heat/Fan
switch in the “center” position. Lockout power
to the heater and check the following:
1. Check the igniter for corrosion and proper
separation. Be sure the insulator is not
cracked and is properly seated in the
burner. Check the connections for clean,
dry, and tight contact. Check the ignition
wire for cuts and cracks that may allow the
spark voltage to jump to ground before the
igniter. Also check that the ignition wire is
securely fastened to the ignition
transformer high voltage terminal.
2. Check the burner ports for obstructions.
Remove any obstruction.
3. Check the electrical system including
wiring, connections, switches, and major
electrical components.
4. Check the input voltage and phase to the
heater; adequate voltage and proper phase
is necessary for proper function.
5. Restore power to the heater and place the
Main switch in the "ON" position then place
the Heat/Fan switch to ‘HEAT’position and
allow the heater to go through its start up.
NOTE: If the burner does not ignite after the
start up, see TROUBLESHOOTING section.
NOTE: The thermostat must be set above
ambient.
Stopping Heater
NOTE: if the heater is being stopped for an
extended period.
1. Turn manual inlet valve to OFF position.

CAMPO EQUIPMENT CO. LTD. (ECOBLAZE)

Tel: [phone] | Fax: [phone] | www.campoequipment.com
pg. 8
2. Place Main switch to “ON” position and
Heat/Fan switch to “FAN” position as well.
3. Allow the heater to cool down for several
minutes; then place the Main switch and
Heat/Fan switch to “OFF” position.
4. Turn off the gas supply at the LP-Gas
cylinder or gas main inlet when the heater
is not in use.
Extended Storage
If the heater is to be shut down for an extended
period, the fuel lines should be cleared from the
primary source to the burner. Clear the lines
by (with the heater running) closing the valve at
the primary source and allowing the heater to
draw the pressure out of the lines. Allow the
pressure to bleed out of the lines until the
burner stops; then place the Main Switch in the
“OFF” position. Close all manual valves.
Disconnect all power and fuel supply lines and
cover all air and fuel line openings.
CAUTION: Never close manual valves at the
primary source and heater inlet at the same
time unless all fuel has been bled out of the
lines. Fuel trapped between the primary
source and the heater in the supply lines will be
subjected to expansion dependent upon
ambient air conditions. Excessive pressure
build-up could occur in the supply line and lead
to line failure. Consult your local gas supplier
for proper piping and gas codes.
When storing the heater indoors the gas
connection between the heater and the
supply cylinder must be disconnected.
Preparing After Extended Storage
Several days or weeks before the heater will be
used, attention should be paid to properly
preparing the heater for service. Since the
heater is an important element of your
operation, it only makes sense that a certain
amount of time is necessary to prepare the
heater. The DF1600 should be inspected
annually by qualified service personnel.
WARNING
Make sure the heater is de-energized before
servicing.
1. Check the igniter for corrosion, damage,
(cracked insulator, etc.), and proper
separation. Make sure that it is secure in
the burner. Replace any igniter beyond
repair.
2. Check the burner gas ports for corrosion
and any obstructions. (See burner
Maintenance Section for cleaning
instructions.)
3. Check the flame rod to be sure it is clean.
Remove any scale or build-up of foreign
matter.
4. Check for wax buildup in the manifold lines.
5. Check the wiring for broken wires or loose
connections. Tighten or replace as
necessary.
6. Check the entire heater for any visual
damage. Repair or replace any damaged
components.
7. Check all unions and valves for leakage or
damage. Tighten or replace as necessary.
8. Do all items in the PRE-START
CHECKLIST; then start the heater to
ensure proper operation.

Belimo and RTC Modulating System
and DFC+ Integrated Gas Fired Heating
control
This system is made up of 3main components,
a variable gas valve or regulator, a discharge
air temperature sensor, and an amplifier
(DFC+) to control them all.
The discharge air temp sensor is mounted in an
air mixing tube, located near the discharge air
side of the heater. Its function is to provide
temperature information to the amplifier
(DFC+). This information is used by the
amplifier to control the “MAX” air temp portion
of the amplifier.
The Belimo or RTC Modulating System
provides for continuous, steady heat, at the
rate required. It does not stop the heater at any
time.
The modulator is the device that does the
actual increasing and decreasing of gas flow to
the burner. An electromagnet controls how
much gas can pass through the modulator. The
more voltage that is applied to the magnet, the
more gas that can pass through. The modulator
is typically full open when a voltage of about
24-volts DC is applied from the amplifier.
Minimum flame results from zero volts DC. The
DF1600 heater has a minimum BTU input
rating of 324538 BTUs on NG (81782 Kcal)
and 326289 BTUs (82223 Kcal) on LP.
The Belimo Modulating System has been
pre-set at the factory to insure this input.
No field adjustment of this set point is
required.
Conventional Remote Thermostat
The optional remote thermostat (if used)
connects to the remote thermostat receptacle
on the heater. The difference is that when this
device is used, the heater delivers a constant
high temperature which is set on the SP of the
RTC DFC+ Controller, until the set temperature
on the conventional thermostat is reached. At
that time, the heater goes to 120°F and keeps
the temperature balanced until the temperature
at the thermostat falls below the set
temperature. The heater then goes back to the
thermostat mode delivers high temperature air.
To use this device, select and position the
thermostat at a location that will represent a
good average room temperature inside the
structure to be heated that will not be directly
affected by the heated air discharge from the
heater. Route the plug end of the cord to the
heater and plug into the special receptacle
located on the heater control panel.
The thermostat assembly comes with a 50-foot
cord with a plug, as standard.
The adjustment range is from 40° to 110° F. (5°
to 43° C.). To use the thermostat, plug in the
remote thermostat to the designated REMOTE
STAT receptaclethen dial upor down or setting
it to the desired room temperature to be
maintained.
MAINTENANCE
WARNING
For your own safety, Lockout electrical
power before attempting any service
procedures to prevent accidental start-up.

Burner
Proper maintenance of the burner is critical for
efficient trouble-free operation. The burner of
every Campo heater is tested before shipment,
however, changes in altitude, fuel,
temperature, and humidity will affect the
performance and efficiency of the burner. Also,
the burner should be checked at least annually
(preferably before the start of the heating
season) for efficient burning.
1. Shut the system down totally,
disconnecting or locking out power supply
so there can be no accidental start-up
during inspection.
2. Inspect the burner carefully, including
upstream and downstream sides of mixing
plates as well as burner body face. Any
accumulation of scale or foreign material on
either side of the mixing plates should be
removed with a wire brush. Check visually
that no holes in the mixing plates are
blocked. If any burner ports are plugged
(even partially) clear them with a piece of
wire or a #47 drill bit (2mm).
WARNING
Do not enlarge burner ports or performance
may be drastically affected.
If any mixing plates are loose or missing
fasteners, tighten/replace as necessary.
Always use zinc plated or stainless fasteners.
3. Observe flame pattern and, if necessary,
take steps to correct obstructed ports. The
velocity and distribution of the air across
the burner is pre-set at the factory and
should be changed by authorized service
personnel only.
Igniter
To start ignition, the igniter must be adjusted
properly and must not be damaged or
defective. Periodically the igniter should be
inspected for damage, corrosion, and
separation. To inspect and adjust the igniter,
use the following procedure:
1. Remove the igniter from the burner.
2. Visuallyinspect the igniter for corrosion and
damage to the insulator and tip.
3. Consult the Specification Sheet for proper
spacing and position.
Pressure Regulator
WARNING
Unqualified service personnel must not
make any adjustments on the regulators!
The pressure regulator on the manifold
functions to reduce the supply of gas to the
burner. There is one pressure regulator on the
main line.
To adjust the main line regulator pressure,
remove the cap of the regulator; then either
turn the adjusting screw out to decrease
pressure or turn the adjusting screw in to
increase pressure. Do not make any
adjustment on the regulators without knowing
what you are doing and having the proper
gauges attached. Also, do not bottom the
adjusting screw.
The heater is designedto operate with a line
pressure upstream of the Maxitrol RV81, of
10 to 14 W.C. (2.24kPa to 3.48kPa). For
maximum efficiency and safety, the
regulator must not be adjusted above this
pressure. The Belimo or RTC modulating
valve varies the gas flow of gas to the
burner to maintain the pre-set discharge air
temperature and has been set at the factory
for optimum performance. Field
adjustments are not required.
CAUTION: Damaged or defective regulators
must be replaced. Also, never exceed the
pressure specifications listed.

TESTING ELECT. COMPONENTS
Common sense and careful thought can make
troubleshooting of electrical problems much
less complicated. Remembering that electricity
must have a completed path for it to work is the
first necessary understanding. Secondly,
search for the problem by looking at the most
obvious solution first; then look toward the
more complicated solutions. Use the
appropriate wiring diagram as a guide for
isolating the problem.
If ignition problems of the burner are
encountered, for instance, use the following
example as a guide.
1. Check the breakers and switches.
2. Check gas supply lines and manual valves,
and fuel availability.
3. Check for proper output voltage from power
source.
4. Check to be sure all wire connections are
tight.
5. Remove the electrode and check its
condition. If worn, replace. If improperly
adjusted, adjust the separation and
extension to within specifications.
The following is the method for testing major
electrical components.
WARNING
A qualified electrician should perform all
tests, replacements, and adjustments.
Testing the Main Switch
Before assuming the Control Switch to be
defective, check the breaker to be sure it is
good. Secondly, be sure to check the wiring
connections and wires to be sure the
connections are tight, and wires are good.
Remember that the blower must be operating
properly for the burner to operate. The switch
can be tested using an ohmmeter.
To test, use the following procedure:
1. Disconnect the main power supply, open
the Electrical Compartment.
2. Set the ohmmeter in the continuity test
mode.
3. With the main switch in OFF position, place
one tester lead on the common contact and
one tester lead onthe contact relative to the
switch position. Place the switch to “ON’
position. The meter must show continuity.
4. With the HEAT/FAN switch in ‘HEAT’
position, place one tester lead on the
common contact and onetester lead on the
contact relative to the switch position. The
meter must show continuity on the relative
contact.
Intermittent Pilot Gas Ignition Control
• Natural or LP gas
• Pilot burner ignition using an external ignitor
• Flame rectification circuit to monitor flame
presence.
• Monitoring of 120V, pilot, and main gas valve.
• Five LED indicators for:
•Running interlock
•Recycle/airflow
•Trial for ignition
•Flame
•Alarm
WARNING
Never touch the flame rod or the wire
leading to it while power is ON. The
amplifier charges the flame rod with
approximately 300 volts AC. Serious
personal injury could result!
Testing Air Pressure Differential Switch
The DF1600 uses an air pressure differential
switch to confirm that the main blower is
moving enough air through the heater.
This switch must be activated before the burner
will ignite. The switch senses the difference
between the velocity developed by the blower.
Any restrictions beyond the set point limit
of the switch to the inlet of the heater will
cause the switch to open and shut the

burner off. All discharge duct work must be
removed before testing the switch.
1. Check the sensing tube from the "HIGH"
port on the switch body to the port right
under the switch for kinks or obstructions.
Insure the sensing line is connected to the
switch. The “HIGH” port sensing tube is
located perpendicular and facing into the
air stream.
2. To test if the switch is functioning,
disconnect and insulate wires leading to the
switch N.O. contacts. Connect an
ohmmeter or continuity light to the switch
N.O. contacts. Placethe Heat/Fan switch to
“FAN” position. The ohmmeter should read
low resistance or the continuity light should
come on. When the blower is stopped the
light should go out and the resistance
reading should be high. If the contacts
remain closed regardless of the blower
status, the air switch must be replaced.
Contact the factory in the event the
switch must be replaced. Only factory
authorized personnel can replace and
calibrate the air switch.
Testing High Limit Switch
The High limit switch is a solid-state device.
When the output contacts are operating
properly, the limit switch will allow the heater to
run when the Heat/Fan switch is placed in the
“Heat” position, as long as the air temperature
at the limit sensor is below the “HIGH LIMIT
that is 150°F”.
