TROUBLE SHOOTING
Improper adjustment, alteration, service or maintenance can cause property damage,
injury or death. This heater must be installed and serviced only by a trained gas service
technician.
If at the onset of ignition, no ignition occurs, the following should be checked.
Lack of power at the input of the controls caused by:

Check the line voltage (120 v)

The thermostat is not calling for heat

The fan is not running and therefore not closing the air proving switch

Blocked combustion air inlet or blockage in exhaust venting

Faulty air flow connection

The blocked flue air switch in open position

The combustion air switch should be in the closed position

Faulty 24 volt transformer

Low voltage supply to unit
Having established power at the control, and still no ignition occurs then the control itself
is suspect and should be changed.
If the igniters operate and still no ignition, then the gas valve is suspect. Be sure that the
main gas supply is on, that the gas cock in the drop line is on, and that the shut off cock
on the gas valve is open. If all gas cocks are open, then power to the gas valve should be
checked. If there is power to the valve and it does not open then the valve should be
replaced.
Continued lockout of the control may indicate that the sensor is not providing the signal
back to the control (flame sensing circuit). If the sensor is in the proper position and the
lockout condition continues, then the grounding connections of the burner, control, and
transformer should be checked. Proper polarity must be maintained in the building
wiring. Reversed polarity or insufficient supply voltage can cause intermittent ignition
failure. If this does not solve the problem, then the control is suspect.
Ignition control modules are solid state; computerized devices that require consistent
supply voltage.
RECOMMENDED MAINTENANCE
Improper adjustment, alteration, service or maintenance can cause property damage,
injury or death. This heater must be installed and serviced only by a trained gas service
technician.
Inspect the entire heater system; venting and gas supply connections, at least annually
prior to the heating season. Replace worn parts and repair deficiencies.
Check the inlet air opening and the blower periodically, cleaning off any lint or foreign
matter. It is important that the flow of combustion and ventilation air must not be
obstructed.
The tube heater burner is completely factory assembled and tested. Any alteration voids
the certification and manufacturer’s warranty. For additional information, contact your
local distributor, or the manufacturer.
