WARNING
!
SAFETY HAZARD
DO NOT attempt to manually light the burner.
Failure to follow this warning could result in property
damage, personal injury or death.
Lighting instructions appear on each unit. Each instal-
lation must be checked out at the time of initial start up
to insure proper operation of all components. Check out
should include putting the unit through one complete cycle
as outlined below.
Turn on the main electrical supply and set the thermostat
above the indicated temperature. The ignitor will auto-
matically heat, then the gas valve is energized to permit
the flow of gas to the burners. After ignition and flame is
established, the flame control module monitors the flame
and supplies power to the gas valve until the thermostat is
satisfied.
See Table 19 & 20 for help in selecting orifices if orifice
change is required. Furnace input rate and temperature
rise should be checked again after changing orifices to con-
firm the proper rate for the altitude.
Installations above 4,000 feet may require a pressure
switch change. If required, use the BAYHALT*** Kit (High
Altitude Accessory Kit) listed in PRODUCT DATA.
TABLE 19
REINSTALLATION OF THE BURNER BOX COVER
Figure 56 shows the correct way to reinstall the burner box
cover if adjustment or replacement of the flame sensor, hot
surface igniter, or main burner orifices have required re-
moval of the cover.

4. Blower door is in place
Flip the switch on main gas valve within the unit to the
“OFF” position. Turn the external gas valve to “ON”. Purge
the air from the gas lines. After purging,
Check all gas connections for leaks with a soapy solution
— DO NOT CHECK WITH AN OPEN FLAME. Allow 5
