WARNING:
THE CONTROL HAS AN INTERLOCK
DEVICE. IF THE STOVE HAS BEEN LIT, IT WILL
NOT RELIGHT IMMEDIATELY. AFTER SHUTTING
OFF ALL GAS FLOW, THE PILOT BURNER
CANNOT BE RELIT UNTIL THE THERMOCOUPLE
HAS COOLED, ALLOWING THE
ELECTROMAGNET TO BE RELEASED (APPROX.
60 SEC.). THE GAS CONTROL KNOB IS
DESIGNED TO OPERATE BY HAND. DO NOT USE
ANY TOOLS DURING THIS OPERATION.

PPEARANCE
Once the unit is lit, observe the flame pattern and
adjust as necessary. Also, a periodic visual check of
the burner flame should be performed. The burner
flames can be adjusted by means of the air shutter.
To determine if the burner flame needs adjustment,
it is necessary to view the flame pattern with the
variable output control knob at its highest setting
(turn fully clockwise). Allow the unit to operate for 10
minutes enabling the entire unit to reach
temperature and for the flame pattern to stabilize.
The flame pattern should be similar to the one
shown in
Figure 13
. There are several guidelines to
aid in determining if the flame pattern is correct:
1. The flame should not be dirty, smoky, sooty, or
lick the top of the stove.
2. The flame should not rise off the TEK burner;
this is called “lifting”.
3. Flames should not impinge heavily on the log
set. They should “fit” through the pre-formed
spaces designed in the log set.
