IMPORTANT

OPERATION OF YOUR FURNACE WITHOUT THE BAFFLE MAY CAUSE UNSAFE

AND HAZARDOUS TEMPERATURE CONDITIONS AND WILL VOID THE

WARRANTY.

Note that secondary air tubes can be replaced without removing the baffle board.

1- Starting with the rear tube, lean and

insert the right end of the secondary air

tube into the rear right channel hole.

Then lift and insert the left end of the

tube into the rear left channel.

2- Align the notch in the left end of the tube

with the key of the left air channel hole.

Using a “Wise grip” hold the tube and

lock it in place by turning the tube as

shown in Detail B. Make sure the notch

reaches the end of the key way.

3- Repeat step 1 and 2 for the other

secondary air tubes.

4- To remove the tubes use the above

steps in reverse order.
