Here are documents and some quick references for the G96VTN Furnace

If the furnace is operating on propane (lp gas), and has the low gas pressure safety switch installed, it is wired into the low air pressure switch for the combustion fan.

If the fault " 3 flashes" is displayed on the G96VTN "A" series, or the fault " 32.2 " is displayed on the G96VTN "B" series, check the propane tank level and inlet gas pressure.

NOTE: 1. A filter is required for each return-air inlet. Airflow performance included 3/4-in. (19 mm) washable filter media such as contained in a factory - authorized accessory filter rack. See accessory list. To determine airflow performance without this filter, assume an additional 0.1 in. w.c. available external static pressure. 2. Adjust the blower airflow setting as necessary for the proper air temperature rise for each installation. 3. Airflows over 1800 CFM require bottom return, two-side return, or bottom and side return. A minimum filter size of 20” x 25” (508 x 635 mm) is required. 4. For upflow applications, air entering from one side into both the side of the furnace and a return air base counts as a side and bottom return 5. The - entry indicates unstable operating conditions

The Main Menu provides access to operating parameters of the furnace control including airflows as well as other diagnostics. See Fig. 37 for the location of the pushbuttons. Scroll through Main Menu by pressing MENU/SELECT button. Press NEXT/OPTION to display the current setting of the parameter (value will flash). Additional presses will scroll through setting options. Press MENU/SELECT button to save a new setting and return to the Main Menu. The display will flash three times to confirm a new setting selection has been saved. Fig. 58 shows the flow of the menu and settings. Table 22 provides additional information on parameter adjustment and applicability.
NFC and Supported App Method
This furnace control board is also equipped with NFC (Near Field Communication) technology which allows the adjustment of operating parameters, diagnostics, and service via a field-supplied mobile device with NFC capability and supported mobile app. Remove 115-V power from the furnace control board to use this method. See Fig. 37 for the location of the NFC antenna. Additional instructions and help may be available through the supported mobile app.
Scan the mobile app QR Code on page 1 of this manual for more information and a link to download the mobile app.

Control Board Replacement
If   the   control   board   must   be   replaced,   the   new   board   must   be programmed with the correct Model Program Number before the furnace will operate. Do NOT program the control board with a Model Program Number different than what is specified on the rating plate. The control may be programmed by either of these approved methods:
1.   Use the supported mobile app to flash the model program onto the board using Near Field Communication (NFC). Scan the QR code on page 1 of this manual for more information and a link to download the mobile app.
2.   Use the correct Super Plug (available from distributor / replacement component) for   the control board to copy the correct model program onto the new board.
Further details and instructions for these programming methods are provided with the replacement control board.
