ARNING
When lit for the first time, the Stowe will emit some
smoke and odors. This is normal “off-gassing” of the
paints and oils used in the manufacturing, and
assembly of the unit. Open windows to vent the
room if necessary. The off gassing and fumes will
subside after the first 10 to 20 minutes of operation.
Once the Stowe in place and connected as
described previously, the unit is ready to be lit for the
first time. Hearthstone tests each Stowe before
shipment, so ignition should take place without
failure.

The Stowe has a piezoelectric spark igniter (the red
or black push button located next to the gas control
valve behind the valve access door), which ignites
the pilot light by means of a spark at the pilot light
assembly. Do not attempt to light the unit with a
match or by any means other than the piezoelectric
spark.

DJUSTMENT
The pilot light is preset by Hearthstone and should
not need adjustment. The pilot light flame must be
large enough to engulf the thermopile and
thermocouple located next to the pilot, but not so
large as to create excessive noise or consume
excessive gas
.
However, it can be adjusted by
means of the pilot light adjustment screw located on
the gas control valve (
see Figure 15
). Remove the
ash lip casting to access the pilot adjustment screw.
Note that the pilot flame must engulf the thermopile
so that the thermopile can generate sufficient milli-
voltage (325 to 500-mv) to power the millivolt gas
control valve.
Before lighting, smell, or use a gas detector all
around the appliance area to check for gas leaks. Be
sure to test near the floor because some gases
(LPG) are heavier than air and will settle on the
floor. If you detect gas, check for leaks.
WARNING!
THE CONTROL HAS AN INTERLOCK
DEVICE. IF THE STOVE WAS RECENTLY
BURNING, IT WILL NOT RELIGHT IMMEDIATELY.
AFTER SHUTTING OFF ALL GAS FLOW, THE
PILOT BURNER WILL NOT RELIGHT UNTIL THE
THERMOCOUPLE HAS COOLED, RELEASING
THE ELECTROMAGNET
(APPROX. 60 SEC.)

NSTRUCTIONS
1. Set the on/off/T-stat switch or thermostat to the
off position.
2. Unplug the blower accessory, if so equipped.
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 (LPG) 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, go to the next step.
5. Turn gas control knob counterclockwise 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 and immediately call a qualified service
technician or gas supplier.
