DOOR REMOVAL
To remove the door, simply pull the door up from the hinges (see
Figure
11
)
. The door adjustment has been set at the factory. If the fit is still not
perfect, you can adjust the door using the hinge screws.
DOOR ADJUSTMENT
The door may need to be adjusted to be completely airtight. The gaskets’
air-tightness can be adjusted using two adjustment screws located on the
right side of the fireplace facade (An Allen key #1/8 – not supplied - will
be necessary for this adjustment).
WARNING
•
Use only a IHP glass doors, specifically designed
for the WRT3920WS fireplace.
•
The fireplace cannot be operated without door.
Consult your dealer to select the correct replace-
ment door.
•
Important! To assure proper alignment of glass
doors: Install this fireplace in a square and
plumb condition, using shims as necessary at
sides and/or bottom.
Checking Door Seal
A one-inch strip of paper may be used to perform a test of the integrity
of the door seal. Close the door on the paper in at least eight points. It
is normal to feel only a slight amount of friction. The door gasket does
not need to be “tight” in all areas, since a small amount of leakage is not
hazardous or detrimental to the performance of your fireplace.
GLASS CARE
Glass Replacement
The glass used for the WRT3920WS fireplace is a high temperature ceramic
glass (1,400° F / 760° C). If the glass breaks, it must be replaced with
an identical ceramic glass. Tempered glass or ordinary glass will not
withstand the high temperatures of the WRT3920WS fireplace. Replace-
ment glass should be purchased from a IHP dealer (see “Replacement
Parts”,
Page 28
)
.
DO NOT OPERATE THE UNIT WITH CRACKED OR BROKEN GLASS.
Glass Cleaning
The WRT3920WS fireplace is designed to keep the glass clean under normal
operating conditions. If the WRT3920WS fireplace is operated continu-
ously with the combustion air controls closed, the glass will tend to get
dirty unless the fuel, firebox and glass are maintained at hot temperatures
(see “Refueling For Best Performance”). To clean the glass, there are a
number of specially designed cleaners. Your IHP dealer can recommend
a suitable cleaner which is available in your area. Regular household
glass cleaners will not clean creosote.
Do not use abrasives such as
steel pads, steel wool or oven cleaner as they will scratch the glass.
DO NOT USE CHEMICAL GLASS CLEANERS ON PAINTED SURFACES
AS IT MAY CAUSE THE PAINT TO PEEL.
CAUTION : DO NOT ALLOW WINDOW CLEANER TO GET IN CONTACT
WITH DOOR GASKET OR PAINT ON FACADE OR DOOR. ONCE CLOSED,
CONTACT OF GLASS CLEANER WITH THE FIREPLACE FACADE CAN
PROVOKE PAINT PEELING OFF.
Gasket Replacement
Remove the door from the unit (see
Page 12
)
and lay it on a clean un-
abrasive surface. To replace the gasket, first remove all of the old gasket
and gasket cement. Make sure that the surface is totally clean before
applying new cement (a high temperature silicone caulking rated at 500°
F [260° C], is suitable) or adhesion problems may result. Apply gasket
cement to the gasket channel and install the new gasket. This replace-
ment part is available from your IHP dealer in the following dimensions:
