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. It 
consists 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" 
(0.3m, 0.46m, 0.6m) lengths. 

The flame rod may be located to monitor only the gas pilot flame or both the gas pilot and main gas 
flames. Mount it with a l/2" “NPT” coupling. 

The following instructions should be observed: 

1.

Keep your flame rod as short as possible. 

2.

Keep your flame rod at least 1/2" from any refractory. 

3.

Your flame rod must 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), extend the electrode tip at least 
1/2" into the flame, but not more than halfway through.

5.

If the flame is partly luminous, the electrode tip must 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 
subtracting from it. This trend sometimes may be reversed by interchanging the primary wires (line 
voltage)  to  the  ignition  transformer.  This  interference  can  also  be  reduced  by  the  addition  of 
grounded shielding between the flame rod and ignition spark.

8

Proven  types  of  flame  grounding  adapters,  as  shown  below,  may  be  used  to  provide  adequate 
grounding surface. High temperature stainless steel should be used to minimize the effect of metal 
oxidation. This assembly may be welded directly over the pilot or main burner nozzle.
