Means OF prOVing adeQuate grOunding area
The proper flame-rod-to-ground-area ratio cannot
always be determined by visual examination or physical
measurement. A positive means of checking the instal-
lation is the measurement of the flame rod current
under actual firing conditions. It is definitely recom-
mended that the installer measure the current flow be-
tween the lead of the flame rod unit and the terminal
in the control terminal board (see Figure 3). Measure
the current with a DC Microammeter or equal. We
recommend a steady output of .9 microamperes or

more. A steady flow of current in this amount under
actual firing conditions will generally indicate adequate
grounding of the pilot flame.
nOte:
1. Read all control data sheet supplied with this heater.
2. Check flame rod for any contact to heater parts. Flame
rod must be free of any contact to heater. Contact with
heater will short circuit flame rod.
3. Cracked porcelain on flame rod will short circuit sensor.
Replace flame rod.
