Protect Against Stray
Light Lockout
Failure to follow these instructions could cause
loss of burner operation resulting in no heat, an
unplanned process interruption, work stoppage
and the potential for frozen plumbing or other
cold weather property damage.
The control must detect a dark, no-fl ame condition
in order to start the burner or it will hold in the
stray light lockout mode.
Shield the burner view window from direct expo-
sure to intense light. y

Protect the Air Tube
From Overheating
Overheating could cause damage to the air tube
and other combustion components leading to
equipment malfunction and impaired combustion
performance.
The end of the air tube must not extend into the
combustion chamber unprotected unless it has
been factory-tested and specifi ed by the appliance
manufacturer.
Position the end of the air tube 1/4” back from fl ush
with the refractory inside entry wall to prevent
damage from overheating. y
