Millivolt wall thermostats are specially designed for use on self-generating systems.  They should never be used on line or low voltage 

a.C. circuits.

 - The thermostat can also be installed on an inside wall 

away from the furnace but in the same room.

It is important to use wire of a gauge proper for the length of the wire:

Proper operation depends on a good pilot flame. The flame must cover 

the top of the thermopile.  Cleaning of the pilot orifice and burner may 

be required due to spiders.

System Check (Figure 10)

a millivolt meter is required to check the system.  Millivolt readings 

should be:

• Across  the  thermopile  terminals,  400-450  millivolts  with 

 

thermostat OFF.

• Across the thermopile terminals, 150 - 250 millivolts with thermostat 

ON

• Across  the  thermostat  wires  at  the  valve,  less  than  30 

 

millivolts with thermostat ON.

• Across  the  thermostat  wires  at  the  thermostat,  less  than  5 

 

millivolts with thermostat ON. (Strong winds, dirty pilot and low pres

-

sure will reduce readings.)

Piezo Pilot Ignitor Instructions

Depressing the button completely causes a spark to occur at the pilot.  

This is a substitute for a match which requires opening the pilot hole 

cover.

To light the pilot, it is important that the electrode be 1/8" (3mm) from 

the thermopile.  The spark must occur at the point the burner flame hits 

the thermopile.  The end of the electrode will be red hot with the pilot 

on.

On a new installation with air in the gas line, it is suggested that a match 

be used.  The match will light the pilot faster than the piezo under this 

condition.
