Prepare for the lighting procedure by adjusting the
thermostat (if equipped) to its lowest setting or OFF
position. If the gas control knob is not in the OFF position,
turn the knob fully clockwise to OFF. Locate the variable
output control knob and turn it fully clockwise to the highest
setting.
Prior to lighting the unit for the first time, wait 5 minutes to
allow any residual gas within the unit to dissipate. Smell all
around the appliance area for gas. Be sure to smell next to
the floor because some gases (LP) are heavier than air and
will settle on the floor. If you do not smell gas after this five-
minute period, proceed with the lighting procedure. If you
do smell gas, DO NOT proceed with the lighting procedure.
Instead,
immediately refer to the ‘What to Do If You
Smell Gas!’ warning on the cover of this manual.
NOTE:
The valve control has an interlock device. After
shutting off all gas flow, the pilot burner cannot be relit
until the thermocouple has cooled, releasing the
electromagnet (approx. 60 seconds). The gas control
knob is designed to operate by hand. Do not use any
tools during this operation. Damaged knobs may result
in serious injury.

Once the Luno 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 light 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.

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 cycles on and off
too often, first try 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.

1. STOP!
Read
the
What To Do If You Smell Gas!
Warning (on the cover of this manual). Ensure the
front door is closed, and the lock screws are in
place.
2. Set the on/off/remote switch or thermostat to the “OFF”
position.
3. Push in and turn the 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 the 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. The 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 the gas control knob counter-
clockwise to “ON”.
8. If the ON/OFF/remote switch is set to “ON”, the stove
should now light. If the remote (or thermostat) is
installed, set the ON/OFF/ remote switch to “remote”
and program the remote to “ON”. Then set the desired
temperature.
9. Shut the gas control valve access door.
10.
If “Remote” was selected, set remote to “ON” and set
desired temperature setting. Normally, if Remote
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 been turned to
the “ON” position, and the ON/OFF/Remote switch is
