DJUSTMENTS
Once the Tudor is set in place, connected and
assembled as described in the “Clearances To
Combustibles”, “Venting Components &
Configurations,” “Electrical Connections”, and “Gas
Supply and Connections” sections of this manual,
the unit is almost ready to be lit for the first time. The
manufacturer tests each unit prior to shipment, so
ignition should take place without failure. However, a
number of small adjustments may be necessary to
compensate for variations in gas pressure, altitude,
and other factors particular to each installation.

ONTROL
The gas control valve is equipped with a variable
output control. This control varies the rate of heat
produced by the unit by varying the gas pressure to
the TEK Burner. A combination of heat output and
the thermostat setting affect the length of the burn
cycle. If your stove turns on and off too often, try,
first, reducing the burn cycle by turning the HI/LOW
knob, on the control valve, to a lower setting. Using
the variable output control, the heat output of the
unit can be reduced for mild fall and spring months,
or maximized for the colder winter months. This
adjustment can be made, by the homeowner, as
necessary by turning the variable output control
knob to “HI”, “LO” or any setting in between.

NOTE:
The gas control knobs and the piezo igniter
are located behind the control valve access door,
under the front of the unit.
1) STOP! Read the What To Do If You Smell Gas!
Warning (on the cover of this manual).
2) Set the on/off/T’stat switch or thermostat to the
“OFF” position.
3) Push in and turn gas control knob clockwise to
“OFF”.
(If not previously lit, the knob should be
in this position.)
4) Wait (5) five minutes to clear out any gas. If you
then smell gas, STOP!
Smell all around the
appliance area for gas. Be sure to smell next to
the floor because some gases are heavier than
air and will settle on the floor. If you smell gas
immediately follow the What To Do If You
Smell Gas! warning on the cover of this Manual.
If you do not smell gas, proceed to the next step.
5) Turn gas control knob counter-clockwise to
“PILOT”.
6) Push in control knob all the way and hold in.
Immediately light the pilot with the gas lighter
(push in and “click” the piezoelectric spark
igniter button several times until lit). Continue to
hold the control knob in for about 20 seconds
after the pilot is lit. Release the knob and it will
pop back out. Pilot should remain lit. If the pilot
goes out, repeat the operation.
If knob does not pop out when released,
stop, shut off the gas supply to the heater
and immediately call a qualified service
technician or gas supplier.
If the pilot will not stay lit after several tries,
turn the gas control knob “OFF” and call a
qualified service technician or gas supplier.
7) After the pilot lights, turn gas control knob
counter-clockwise to “ON”.
8) If the ON/OFF/T’stat switch is set to “ON”, the
stove should now be lit. If the thermostat (or
remote) has been installed, set the ON/OFF/
T’stat switch to “T’stat” and turn the thermostat
(or remote) to “ON”. Then set the desired
temperature.
9) Shut the gas control valve access door.
10) Plug in the fan accessory, if so equipped.
11) If T’stat was selected, set thermostat to “ON”
and set desired temperature setting. Normally, if
T’stat position was selected, the main burner is
cycled on and off by the thermostat or the
“on/off” switch located on the bottom of the
thermostat body.
Note:
When pressing/clicking the piezoelectric spark
ignition button to light the pilot, watch through the
glass (front) of the unit. Click the igniter button until a
flame is visible at the pilot. Once the pilot is lit,
continue to press on the gas control knob for
another 20 seconds, then release. Ascertain that the
pilot is still lit by looking through the front door. If lit,
then turn the gas control knob fully counter-
clockwise to the “ON” position. If the pilot fails to
light, or if it went out due to a premature release of
the gas control knob while depressed in the “PILOT”
position, wait 60 seconds for the Interlock to release.
Then repeat the lighting process as described in this
section of the manual.
Once the pilot is lit, the gas control knob is turned to
the “ON” position, and the ON/OFF/T’stat switch is
turned to “ON”, the main burner should light
immediately. If you would like to use the thermostat
and it has been installed, switch the ON/OFF/T’stat
switch to thermostat. Turn the thermostat to "ON"
and set it to a higher position so that it "calls" for
heat in order to light the main burner (i.e. turns the
unit on). Note that the thermostat controls the on/off
