Battery Replacement
WARNING: DISCONNECT POWER TO THE UNIT
AND SHUT OFF THE GAS SUPPLY TO THE
VALVE BEFORE REPLACING ANY BATTERIES.
Hearthstone recommends replacing all batteries at
least every season. Keep a supply of good quality
rechargeable batteries on hand to ensure
functionality during power outages, and to give the
environment a break.
Remote Transmitter Battery Replacement
You can easily change the Remote Transmitter
batteries by accessing the rear cover plate. Ensure
you orient the batteries correctly as indicated in the
battery compartment.
Receiver Battery Replacement
1. Move the switch to the OFF position. Remove
the cover plate screws and pry the entire plate
with the switch off the receiver’s battery
compartment.
2. Install four new AA batteries. Ensure you orient
the batteries correctly as indicated on the battery
compartment cover.
3. Ensure the switch is still in the OFF position,
align the slider with switch stem and snap the
cover plate back onto the battery compartment.
4. Replace the cover plate screws.
Initializing the Remote Control
Whenever you replace the batteries, you must
synchronize communication between the Receiver
and the Remote Control transmitter.
1. Place the slider switch in the REMOTE position.
2. Insert the end of a paper clip into the hole
marked PRG on the Receiver cover. The
Receiver will beep three times to indicate it is
ready to synchronize with the Remote Control.
3. Install three AAA batteries in the Remote
Control, and push the ON button. The Receiver
will beep four times to indicate the Remote’s
command is accepted and is set to the particular
code of that Remote. The system is now
initialized.
Professional Inspection
Once a year, have the unit, and venting system
inspected by qualified service personnel to ensure
that they are clean, free of obstruction, safe, and in
good working order. If service or maintenance is
required, have qualified service personnel perform it.
As Needed:
Glass and Gasket Replacement
In the event that you need to repair or replace a
cracked or broken glass or gasketing use the
following instructions to replace the components. For
a broken glass ask for kit #97-58710 from your
Authorized Hearthstone Dealer. Your Tucson uses a
folded flat fiberglass gasket to make a tight seal
between the glass frame and the firebox. In time, the
gasket can become brittle and compressed and
should be replaced. New gasket material is also
available from your Authorized Hearthstone Dealer.
Protect your hands with work gloves, and wash up
later.
1. Allow the Tucson to cool completely. Remove
the glass from the glass frame by drilling out the
four 1/8” rivets that lock the glass in place. Pull
the glass away from the frame and set it aside.
2. Remove the existing gasket from the glass by
grasping one end and pulling firmly. Clean off as
much of the hanging fiber “hairs” as possible
3. Locate the 1” x1/8” flat tape gasket. Peel the
adhesive protecting paper away from one end.
Starting at the center of the long end of the glass
apply the gasket centered on the edge of the
glass. Continue to wrap the gasket around the
edge until you meet at the starting point. Do not
overlap the gasket ends or leave ends with
ragged edges.
4. Firmly and evenly, fold the gasket around the
edges of the glass so it lies flat on the surface.
5. Place the gasket back in the glass frame. With
four new 1/8” rivets replace the 2 glass clips.
The glass and frame are now ready to be placed
back on the unit.
