6b To light the pilot, move the lighting hole cover aside
(see Fig. 1) and place a lighted match into the hole.
Depress the gas valve knob and hold while lighting
and observing the pilot burner. Ensure that the pilot
burner ignites from the match. Allow the pilot to burn
approximately 30 seconds before releasing the gas valve
knob. If pilot does not remain lighted, repeat the lighting
operation allowing a longer period of time before
releasing the gas valve knob.
NOTE: In cases where long runs of gas supply lines have been
installed ahead of the appliance, it may be necessary to bleed
trapped air out of the supply lines before lighting the pilot.
New installations generally require bleed of supply lines. Wait
a minimum of five minutes after bleeding the supply lines
before attempting to light the heater.
Adjust pilot if necessary as noted under “Pilot Burner
Adjustment.”
