NOTE:
If the air curtain will not start on the initial start up, the ignition
controller may require resetting. This occurs when ever the unit has
been on a prolonged stand-by period.
This unit is fitted with an automatic spark ignition. When proper airflow for combustion
is proven by the air proving switch and a pre-purge period has elapsed, the integral
igniter and gas control valve operates. The ignition spark ignites the burner and the
flame is detected by the flame sensor. If a burner flame is not detected, the ignition
controller will require manual resetting.
NOTE:
If the air curtain will not reset, use the flow chart in “Trouble Shooting the
Burner Controls”
Section 9.0
to reset the unit.
To startup the air curtain:
•
On the remote console (see photo on page 15), activate the
“Power”
switch to
“ON”

“Heat”
switch to
“ON”
. The air curtain exhaust
fan should now start.

“Power”
switch
to
