DYNAVENT

®

 WARNING: Never use an open

flame to check for a leak. Apply a
mixture of liquid soap and water
to all joints. Bubbles forming show
a leak. Correct all leaks at once.

vent(s) (see Figures 9 and 10).

2.

Remove two screws on front lower
flange that attach furnace flange to fur-
nace cabinet flange (see Figure 11).

Note:

tom shield (see parts list, page 22, for
location). Removing two screws will
detach bottom shield.

3.

7.

Rotate the 3/8" manifold elbow 90

°

 so

the opening is pointing downward (see
Figure 12).

8.

Locate knockout plug in furnace cabi-
net. Knockout plug is in lower left rear
of furnace cabinet (as viewed from rear,
see Figure 13). Remove knockout plug.

9.

Slide furnace back into furnace cabi-
net. Make sure exhaust tube gaskets are
in place. Make sure exhaust and intake
vent tubes extend into vent caps on
back of cabinet. Replace two screws by
exhaust vent(s) removed in step 1.

pages 9 and 10 for correct gas pipe in-
stallation.

12. Check connections for gas leak.

13. Caulk around pipe or nipple. This pre-

vents cold air entering knockout hole.
