Does the ehauster NO
fan turn on?
Is the power at the
exhauster 120V?
NO
YES
Find the source of the
electrical problem.
Remove obstruction
& lubricate fan.
YES
Does the igniter warm up
and glow orange?
NO
Is the exhauster
obstructed?
YES
Is there 24V going
from the exhauster
assembly to the
burner control box?
YES
NO
Check voltage on the
secondary side of
transformer. It is 24V?
The fan is faulty and
must be replaced.
NO
NO
Wiring is faulty between the
exhauster assembly and the
burner control box.
YES
Replace power box.
Transformer is faulty.
YES
Is the igniter
physically damaged?
Replace igniter.
YES
NO
NO
8
Check voltage at igniter during the
YES
ignition sequence (usually 5
seconds after power to burner
control box). Is it 24V?
Is the resistance through
the igniter 1 to 6 ohms?
YES
Replace faulty
wiring.
NO
Is the inlet or the outlet of the unit
obstructed? I.e. ice, bird’s nest, dirt, etc. NO
YES
Check for loose wiring
or restrictions in hose
connections to the
pressure switch. Are
they ok?
Remove obstruction.
YES
Temporarily place jumper across the
pressure switch and chack for 120V
going from switch to circuit board.
(Be sure to reinstall the cover.) Is
there 120V entering the circuit board?
NO
Faulty wiring. Repair or
replace wiring.
NO
Repair wiring
or hose
connections.
NO
YES
Replace circuit board.
The heater is equipped with a safety
pressure switch. The switch is a
normally open swtich and located in
the gas valve compartment.
Temporarily place a jumper across the
terminal of the switch. (Be sure to
reinstall the cover.) Does the ignitor
spark?
YES
Replace the switch after verifying the
following:
* Baffle(s) is in the tube(s) farthest
from the burner.
* Heater, fan blower, squirrel cage,
intake and exhaust are clean and free
from dirt and obstructions.
* The 4” air intake pipe does not
exceed 20 feet and/or 2 elbows.
* There is not a negative pressure
experienced at the area of air intake
(ie: attic space, high-winds, very tight
building).
SV Series - 4” Tube Heater Installation, Operation, Maintenance and Parts Manual
SV Troubleshooting Flowchart
Turn up thermostat.
Test for 24V at valve
during valve opening
period (usually 5
seconds after power to
the heater). Is there
24V to valve?
NO
YES
Possibly, the circuit board
and/or wiring harness is
faulty. These should be
replaced.
NO
Check to make sure gas pressure is
within minimum and maximum inputs, NO
as indicated on AGA burner rating
label. Is gas pressure OK?
YES
Correct
problem.
NO
Check to make sure gas pressure is
within minimum and maximum inputs,
as indicated on AGA burner rating
YES
label. Is gas pressure OK?
YES
YES
Is the gas cock in
the ON position?
Replace
gas valve.
Correct
problem.
Make sure gas lines
were purged of air
YES
Does the burner
light?
NO
Is the proper gauge wire
used between exhauster
and assembly and burner
control box?
YES
YES
Check voltage at burner box
during ignitor warm up. Is
voltage at least 24V?
NO
NO
9
Use proper
wire.
Does the burner
stay on?
Use larger gauge wire.
NO
Does the burner stay on for
approx. 15 seconds and then YES
shut off?
YES
Does heater stay on
until call for heat ends?
NO
YES
The following can cause the
heater to shut down:
* Improper grounding.
* High winds.
* Taking combustion air from
the attic.
* Dirty environment.
* Baffle not located properly.
* Fluctuating gas pressure.
Troubleshooting ends.
Is the heater properly grounded?
Is the heater’s polarity correct?
NO
YES
NO
NO
Does the burner
come on and then
turn off immediately
(1 or 2 seconds).
YES
Certain models have a separate glo-bar ignitor
and flame rod sensor located next to the globar. Other models have a glo-bar ignitor only,
which acts as both an ignitor and flame sensor.
Does model in question have glo-bar ignitor
only?
Correct problem.
Consult factory for
proper parts.
NO
NO
YES
Check to make sure that the pressure is NO
within minimum and maximum inputs as
indicated on the AGA burner rating
label.
Is gas pressure OK? YES
With voltmeter, check DC
voltage at flame rod. Is it greater
than 30 Volts DC?
Correct
problem.
Exhaust pressure
switch may be
faulty or there is a
restriction in the
exhaust.
Sensing rod is faulty or
flame is weak. Check to
make sure heater is
operating at proper gas
pressure as indicated on
AGA burner rating label
and then replace sensing
rod if needed.
YES
Check to make
sure flame sensor
wire is OK and
then replace
circuit board.
