4 Troubleshooting

With proper installation, operation, and maintenance your gas appliance will provide years of trouble-free service. If you do experience a problem, this troubleshooting guide will assist a qualified service technician in the diagnosis of a problem and the corrective action to be taken. This troubleshooting guide can only be used by a qualified service technician. Contact your dealer to arrange a service call by a qualified service technician.

A. Standing Pilot Ignition System

 

Symptom

Possible Causes

Corrective Action

1. After repeated triggering

A. No gas or low gas pressure.

Check the remote shut-off valves from the appliance. Usually, there

 

of the red or black piezo

 

is a valve near the gas main. There can be more than one valve

 

ignitor button, the spark

 

between the appliance and the main.

Check the LP (propane) tank. You may be out of fuel.

 

pilot.

 

 

 

 

C. Ignitor.

Check the spark at the electrode and pilot. If no spark and electrode

 

 

 

 

 

wire is properly connected, replace the ignitor. Verify that there is no

 

 

 

short in electrode wire.

 

 

D. Pilot or misaligned electrode

Using match, light the pilot. If the pilot lights, turn off the pilot and

 

 

(spark at electrode).

trigger the piezo ignitor button again. If the pilot lights, an improper

 

 

 

gas/air mixture caused the bad lighting and a longer purge period is

 

 

 

recommended. If the pilot will not light, ensure the gap at the elec-

 

 

 

trode and pilot is one-eighth in. to have a strong spark. If the gap is

 

 

 

OK, replace the pilot.

2.

The pilot will not stay lit

A. Thermocouple.

Check that the pilot flame impinges on the thermocouple. Adjust the

 

after carefully following

 

pilot for proper flame impingement.

 

the lighting instructions.

 

Ensure that the thermocouple connection at the gas valve is fully

 

 

 

 

 

 

inserted and tight (hand tighten plus 1/4 turn).

 

 

 

Verify proper voltage output from the thermocouple to the valve.

 

 

 

Place one millivolt meter lead wire on the thermocouple copper lead.

 

 

 

Place the second lead wire on the solder button on the back of the

 

 

 

valve (blue wire). Start the pilot and hold the valve knob in. The

 

 

 

millivolt reading should read 8-16 millivolts. If millivolt reading is

 

 

 

less than 8 millivolts, replace thermocouple.

 

 

B. Improper gas inlet pressure.

Natural gas should be 5-14 in. w.c. LP should be 10-14 in. w.c.

 

 

 

Verify pressure with manometer.

 

 

C. Valve.

If the thermocouple is producing 8-16 millivolts, replace control valve.

3.

The pilot is burning,

A. On/off switch or wires.

Check the ON/OFF switch and wires for proper connections. Place

 

there is no burner

 

the jumper wires across the terminals at the switch. If the burner

 

flame, the valve knob is

 

comes on, replace the switch. If the switch is OK, place the jumper

 

in the ON position, and

 

wires across the switch wires at the gas valve. If the burner comes

 

the ON/OFF switch is in

 

on, the wires are faulty or connections are bad.

 

the ON position.

 

 

 

B. Thermopile may not be gen-

Check that the pilot flame impinges thermopile properly.

 

 

 

 

erating sufficient millivoltage.

Be sure the wire connections from the thermopile at the gas valve

 

 

 

 

 

 

terminals are tight and that the thermopile is fully inserted into the

 

 

 

pilot bracket.

 

 

 

Check the thermopile with a millivolt meter. Take the reading at

 

 

 

TH-TP&TP terminals of the gas valve. The meter should read 350

 

 

 

millivolts minimum, while holding the valve knob depressed in the

 

 

 

pilot position, with the pilot lit, and the ON/OFF switch in the OFF

 

 

 

position. Replace the thermopile if the reading is below the specified

 

 

 

minimum.

 

 

 

With the pilot in the ON position, disconnect the thermopile leads

 

 

 

from the valve. Take a reading at the thermopile leads. The read-

 

 

 

ing should be 350 millivolts minimum. Replace the thermopile if the

 

 

 

reading is below the minimum.

Hearth and Home Technologies (HHT) has long been a leader in the hearth industry, and their line of gas fireplaces is a testament to their commitment to innovation, quality, and user satisfaction. Among their notable products are the CFL-24LP-IPI, CFL-30LP-C, ST-CFL-24LP-B, CFL-24LP-C, and CFL-30NG-C models, which offer a wide array of features designed to enhance warmth and ambiance in any living space.

One of the standout features across these models is the innovative "Intermittent Pilot Ignition" (IPI) technology found in the CFL-24LP-IPI. This system allows for greater energy efficiency by igniting the burner only when the fireplace is in use, reducing gas consumption and saving on utility bills. This energy-efficient design is complemented by a range of realistic flame effects that can be adjusted to suit user preferences, bringing the allure of a traditional wood fire into a modern gas appliance.

The CFL-30LP-C and CFL-30NG-C models target larger spaces with enhanced heating capacity and design flexibility. With their impressive dimensions, these units can effectively serve as the focal point of a room while providing ample warmth to larger areas. Featuring a variety of trim and finish options, they easily match diverse interior styles, from contemporary to classic.

Another significant aspect of these models is their user-friendly controls. Many units come equipped with remote control functionality, allowing users to adjust flame height and temperature settings without leaving their seats. This convenience is further amplified by the installation of a thermostat mode that helps maintain a consistent room temperature, enhancing overall comfort.

The ST-CFL-24LP-B and CFL-24LP-C models emphasize size without compromising style or performance. These compact options are perfect for smaller spaces, yet still deliver robust heating capabilities and the elegant aesthetics associated with Hearth and Home Technologies.

All these models adhere to high safety standards and include features such as automatic shut-off valves and glass doors to prevent accidental contact with the flame. Additionally, they are designed for easy maintenance and service, ensuring longevity and consistent performance.

In conclusion, Hearth and Home Technologies’ gas fireplace range brings together efficiency, style, and advanced technology.
