not interfere with each other. When looking at the U-shaped configuration from behind, the burner control box is on
the left and the exhauster assembly is on the right. See Figure 2.5.

3.0 Operation
NOTE: Reference the Tube Heater General Manual (F/N: LIOGTa) for installation requirements.
Sequence of Operation
Starting Circuit: Upon a call for heat, the exhauster fan energizes creating a negative air pressure
allowing the differential pressure switch to close. A low voltage circuit is completed from the
secondary side of the transformer to the ignition module. After a five (5) second delay, the igniter is
powered. After seven (7) seconds, gas valve opens initiating the ignition trial. If flame is not sensed
after 15 seconds, the heater will attempt to re-ignite for a total of three (3) trials for ignition before
entering lockout mode.
Running Circuit: After ignition, the flame rod monitors burner flame. If sense of flame is lost, the control
closes the gas valve within one second and a new trial sequence (identical to the starting sequence)
is initiated. If flame sense is not established within 15 seconds, the heater will attempt two (2)
additional ignition sequences before entering lockout mode. The control can be reset by briefly
interrupting the power source.
This heater must be installed and serviced by trained gas installation and service
personnel only.

Test for 24V at valve during
opening period (usually 7
seconds after power to heater).
Is there 24V to the valve?
Check voltage on the
secondary side of the
transformer. Is it 24V?
Is 24V going from the
exhauster power box
assembly to the burner
control box?

physically damaged?
Is the inlet or the outlet of
the unit obstructed (i.e.,
ice, birds nest, dirt, etc.)?

Check for loose wiring
or resistance in hose
connection to pressure
switch. Are they ok?
The Heater is equipped with a safety pressure
switch. This differential switch, located in the
ignition controls compartment, is a normally
open pressure switch. Temporarily place
jumpers across the terminals of the switch (Be
sure to reinstall the burner control box cover).
Does the light energize?
Replace circuit board.
Check voltage at igniter during
ignition sequence (usually 7
seconds after power to the
burner control box). Is it 24V?

dirt and obstructions.
• The 4” air intake pipe does not exceed 20 feet and/or 2 elbows.

immediately (1 or 2
seconds)?
Check to make sure gas pressure
