INSTALLATION - 69ND1 FLAME ROD
The 69NDl flame rod proves a gas pilot flame and/or main gas flame. It is a spark plug type unit con-
sisting of 1/2' “NPT” mount, a KANTHAL flame rod, a glazed porcelain insulating rod holder and a
spark plug connector for making electrical connections. The 69ND1 is available in 12", 18" or 24"
lengths.
The flame rod may be located to monitor only the gas pilot flame or both the gas pilot and main gas
flames. It is mounted on a l/2" “NPT” coupling.
The following instructions should be observed:
1.
Keep flame rod as short as possible.
2.
Keep flame rod at least 1/2" from any refractory.
3.
Flame rod should enter the pilot flame from the side so as to safely prove an adequate pilot
flame under all draft conditions.
4.
If the flame is nonluminous (air and gas mixed before burning), the electrode tip should extend
at least 1/2" into the flame, but not more than halfway through.
5.
If the flame is partly luminous, the electrode tip should extend only to the edge of the flame. It is
not necessary to maintain uninterrupted contact with the flame.
6.
It is preferable to angle the rod downward to minimize the effect of sagging and to prevent it
from coming in contact with any object.
7.
An adequate grounding surface for the flame must be provided. The grounding surface in actual
contact with the flame must be at least 4 times greater that the area of the portion of the flame
rod in contact with the flame. It is essential to adjust the flame rod and ground area ratio to pro-
vide a maximum, signal reading.
Note: Interference from the ignition spark can alter the true signal reading by adding to, or sub-
tracting from it. This trend sometimes may be reversed by interchanging the primary wires (line volt-
age) to the ignition transformer. This interference can also be reduced by the addition of grounded
shielding between the flame rod and ignition spark.
SYSTEM INFO SUB-MENU
The sub-menu "SYSTEM INFO" allows the user to review information pertaining to the operation
of the control (e.g. average main flame signal strength, status of the high fire and low fire end
switches, etc.). This information can be very helpful when setting the damper linkages on the firing
rate motor. The user may also clear the internal burner history (burner hours, cycles and system
hours), number of lockouts and stored lockout information.
Language choices of English, French, Spanish, Dutch, German and Swedish are available.
The MODE key is used to enter and exit the "SYSTEM INFO" sub-menu, and the NEXT and BACK
keys are used to advance through the sub-menu.
