indicated on the serial plate, is not 5% less than the rated
voltage.
21. Check the gas inlet pressure at the unit upstream of the
combination gas control. The inlet pressure should be
6-7" W.C. on natural gas or 12-14" W.C. on propane. If

atmosphere.
2. To prevent premature heat exchanger failure, the input to
the appliance as indicated on the serial plate, must not
exceed the rated input by more then 5%.
3. To prevent premature heat exchanger failure, observe
heat exchanger tubes. If the bottom of the tubes become
red while blower and furnace are in operation, check to
be sure the blower has been set to the proper rpm for the
application. Refer to page 13 for Blower Adjustments.
4. Start-up and adjustment procedures should be performed
