UNPACK & INSPECT FOR DAMAGE

 

Unpack 

The Tucson is packaged by the manufacturer to 
withstand shipment without damage under most 
circumstances.  However, damage can occur 
during transit and handling.  Care should be taken 
when unpacking, inspecting for damage,  and 
installing the unit.  

If any  damaged or missing 

parts are detected, immediately contact your 
dealer.

 

 
After removing the shipping carton, carefully 
remove the top three stones and grill.  Use the 
protective wrapping material to temporarily 
protect the stones from chipping or damage while 
the unit is inspected and installed. 
 
With the top stones and grill removed and set 
aside, undo the lag bolts that fasten the unit to the 
pallet.  Take care not to mar or chip the legs if 
enameled.  Lift the stove off the pallet and set it 
in place, (with regards to the Clearances To 
Combustibles section of this manual.) 

 

 
 

Inspect for damage

 

I

nspect the Tucson for visible and/or concealed 

damage. The unit should appear to be square and 
true.  The stones should be whole and without 
cracks, chips, or breakage.  The sheet metal parts  
should be smooth and free of bends and/or dents. 
 
If the heater is enameled, the enameled cast iron 
should be free of chips and/or cracks.  If visible or 
concealed damage is found or suspected, contact 
your local dealer for instructions. 
 
The Owner’s Manual, thermostat (with wire), 
removable ash lip, and the decorative ceramic fiber 
logs, supplied with the Tucson, are contained within 
the firebox.  It is important to wear the safety 
goggles and gloves when handling the log set.  
Open the firebox door using a 5/32 allen wrench 
and inspect the logs for damage.  If a damaged log 
is encountered, contact your local dealer for 
replacement logs.  Put the logset, thermostat, and 
the ash lip aside.  They will be installed later.
