Installing The Observation Port; Installing The Air Outlet Louvers - Saturn 125 Operator's Manual

Installing the Observation Port

CAUTION: To prevent serious personal injury, the observation port must be correctly installed
according to the following procedure. A properly installed observation port permits safe observation of
the flame during furnace operation. Be sure to follow all safety procedures as outlined in this manual when
observing the flame through the port.
1. Refer to Figure 3B.
2. Use a 1/4" nut driver to remove the two (2) self-tapping screws from the half-moon piece.
3. Position the half-moon piece and the faceplate on the observation port, and install the two
self-tapping screws.
4. Open the port and make sure the faceplate moves and closes freely. If the faceplate hangs up,
loosen the hex-head screws slightly until the faceplate closes correctly.

Installing the Air Outlet Louvers

Air Flow Discharge Installation Guidelines:
•
It is very important to properly install the louvers to direct the flow of hot air away from the furnace. The
air flow may be directed front, back, or to either side depending on how the louvers are installed.
• Note that each furnace is supplied with four (4) louvers which may be installed all in the same direction
OR the louvers may be split for partial air discharge out either side or front to back.
•
When determining the placement of the air discharge louvers, you also need to consider the required
clearances from combustibles as stated in Section 4 of this manual.
•
DO NOT restrict the flow of the hot air from the furnace by keeping the louvers completely closed, or the
furnace may not operate properly.
