THC-175DF SERIES TROUBLESHOOTING ANALYSIS

PLEASE NOTE: In order to facilitate trouble shooting, unit panels have been removed in some of these

pictures for ease of identification only. All panels and fasteners must be in place as provided by the

manufacturer to ensure the safe and efficient operation of this gas fuelled appliance.

PROBLEM: UNIT IS OVER HEATING.

POSSIBLE CAUSE: Fuel selector valve is in the wrong position.

WARNING DAMAGE TO HEATER WILL OCCUR.

REMEDY: Ensure the fuel selector valve is in the correct

position as per label.

Propane – crossing the supply pipe.

Natural Gas – in line with the supply pipe.

PROBLEM: NO HEAT, FAN OPERATES.

POSSIBLE CAUSE: Rear of heater is blocked.

REMEDY: Ensure rear of heater is unobstructed

and proper rear clearances are maintained.

(see approval label for specifications)

POSSIBLE CAUSE:If the rear of the heater is obstructed, the snap

disc manual reset limit may trip and must be

reset manually before the fan can operate.

REMEDY: The high temperature limit switch reset button

is found behind the louvers on the rear of the heater,

DISCONNECT THE POWER TO THE HEATER.

Use a non-metallic slim tool, insert carefully through

louver opening and push the “red” button to reset the

switch OR remove the louvered rear panel door and

push the “red” reset button. Make certain to re-close

the panel before operating the appliance.

POSSIBLE CAUSE:Faulty On-Off switch.

PROBLEM: HEATER WILL NO LIGHT.

POSSIBLE CAUSE: Gas Supply.

REMEDY: Ensure required gas supply pressures are available to the heater.

(see approval label for specifications).

POSSIBLE CAUSE: Gas Valve / Solenoid.

REMEDY: Ensure solenoid is energized. (use volt meter).

Ensure plunder in solenoid is being activated. (use manometer at test point after solenoid).

POSSIBLE CAUSE: Igniter / Flame Sensor

REMEDY: Ensure the gap between the igniter and sensor is

approximately 1/8” – 3/16”. DO NOT adjust the

porcelain side of the igniter as permanent damage

may result.

Check igniter wire connections.

Ensure igniter spark is strong.

Replace igniter assembly if necessary.

POSSIBLE CAUSE: Ignition Board.

REMEDY: Ensure electrical signals for igniter and gas valve /

solenoid are present.

Ensure ignition board is properly grounded.

POSSIBLE CAUSE: Thermostat.

REMEDY: Ensure that the thermostat is calling for heat (if it is,

the fan will start). Please not that as a safety measure

the thermostat is equipped with a 10 second delay.

If your heater is equipped with an optional external

thermostat check that connections are secure and restart

the heater. If the heater fails to restart, remove the optional

line thermostat and restart the heater to confirm operational

status. If the heater starts, replace the thermostat.

PROBLEM: HEATER WILL NOT REMAIN LIT AFTER START UP.

POSSIBLE CAUSE: Faulty igniter wire.

REMEDY: Check igniter wire for any damage. Replace is necessary.

POSSIBLE CAUSE: Faulty igniter / flame sensor.

REMEDY: Ensure connections are secure. Replace igniter / flame

sensor if necessary.

POSSIBLE CAUSE: Ignition board.

REMEDY: Check ground wire for proper connection.

Check polarity of extension cord compared to polarity

of plug on the heater.

Replace faulty ignition board.

POSSIBLE CAUSE: Thermostat.

REMEDY: Ensure thermostat is calling for heat. NOTE: If the

thermostat is not calling for heat, the heater will not operate.

PROBLEM: ELECTRICAL.

POSSIBLE CAUSE: All components.

REMEDY: Before replacing any component, all connections must be checked to ensure the

electrical circuit is complete. (Use volt meter and enclosed wiring diagram).

Any point in the circuit where 120v is not achieved indicates location of problem

and/or possible faulty component. NOTE: Everything downstream of the

transformer is 24v (eg. all switches and sensors).

PROBLEM: PIPING.

POSSIBLE CAUSE: All pipe fittings.

REMEDY: When loosened, tightened or replaced, the complete fitting should be removed

and approved pipe sealant applied to all male threads before reconnection
