Installing the Control

This ignition system can be mounted from 0 to 90 degrees 
in any direction including vertically from the upright 
position of the ignition system control switch.

IMPORTANT

Make sure to mount the replacement control 
in the same location and orientation as the 
original control.

1.

Mount the control so the gas flow is in the direction 
of the arrow on the bottom of the ignition system 
control, as shown in Fig. 4.

2.

Apply a moderate amount of good quality pipe com-
pound to the pipe, leaving the two end threads bare, 
as shown in Fig. 5. For LP controls make sure to 
use an LP resistant pipe compound.

3.

Remove the seals over the ignition system control 
inlet and outlet if necessary.

4.

Thread the pipe the amount shown in Table 1. Do 
not thread the pipe too far, because this could 
cause valve distortion or malfunction.

5.

Using a wrench on the square ends of the ignition 
system control, connect the pipe to the ignition 
system control inlet and outlet.

Fig. 4.  Mount so gas flows in the 

direction of the arrows.

NOTE: If the control has a flange, place the wrench on 

the flange instead of on the ignition system con-
trol, as shown in Fig. 6.
