14. Set the thermostat to desired setting.
Note: Setpoint must be above actual water
temperature or burner will not fire.
15. The blower should come on immediately, and after
about 15 seconds, the burner should fire. When
operating for the first time, the burner may not fire
on the first try because of air in the gas line. If it
does not fire at first, push the ON/OFF button, wait
five minutes, and again push the ON/OFF button.
The burner should fire after about 15 seconds.
You may have to repeat this until all of the air has
cleared the gas line.

reaches the desired temperature set on the
thermostat. The blower will continue to run for
about 60 seconds after the burner shuts off. If any
of the safety interlocks should open during burner
operation, the burner shuts off immediately, but
the blower continues to run for about 60 seconds.
Should overheating occur or the gas supply fail to
shut off, turn off the manual gas control valve to the
appliance.
