Troubleshooting kit (continued)
7.3 A TEMPERATURE INDICATOR DOES NOT WORK
Solutions
1. Turn the control panel key to the Off position, then back to the On position.
• If the potentiometers as well as the fans are working, the indicator must be replaced. Contact your LAPIERRE
EQUIPMENT service centre for a replacement.
2. Check that the circuit breakers in the electrical box are in the On position.
3. Turn each of these circuit breakers Off and On.
4. If the problem persists or is repeated, contact your LAPIERRE EQUIPMENT service centre.
7.4 ONE OR TWO TEMPERATURE INDICATORS SHOW ERRATIC
VALUES OR AN ERROR MESSAGE
In normal operation, when the evaporator has been running for more than 15 minutes, the temperature of the
combustion chamber must be at least twice that of the chimney. For example, if your chimney is at 842 °F
(450 °C), the combustion chamber must be at least 1652 °F (900 °C).
FREQUENT REPLACEMENT OF SENSORS | Frequent replacement of one or both temperature sensors
indicates that the building grounding is defective. This situation must be corrected. Electrical work must be
done by a qualified contractor.
Solutions
1. When the evaporator is cold, both temperature indicators should show identical temperatures at +- 3.6 °F (2 °C).
• Identify which temperature indicator is definitely in sync with the building’s ambient temperature, and
which is inconsistent.
• Replace the temperature sensor in the indicator that is out of sync (see items 3 or 4 below, as applicable).
2. If both indicators show erratic values or error messages, contact your LAPIERRE EQUIPMENT service centre.
3. Combustion chamber indicator
If the combustion chamber temperature indicator shows an error message or values that are erratic, constantly
unstable and significant, proceed with the following steps.
• Remove the temperature sensor connection cover.
- It is located in the middle of the evaporator, on the right side when facing it.
