Periodic Inspection
Follow these steps for periodic inspections:
1.
Check to verify that the vent system and vent cap are open and free of blockage.
2.
Before re-installing glass, have qualified service person check the operation of the pilot and cycle the burner per lighting
instructions. Be sure all items in lighting and installation checklists are completed.
3.
Periodic visual check of pilot flames is required. Pilot flame must overlap flame sensor and burner ignition ports always.
Especially for LP gas applications, always verify visible pilot flame length is at least 1" long.
4.
Periodic visual check of main burner’s rear and front flames is required.

How do I clean the viewing glass?
The viewing glass should be cleaned periodically
.
Exterior glass surface may be cleaned with cleaner as desired. To clean interior
glass surface, use Kel Kem Polish Plus (part # 65-06-00455) or a comparable product.
Caution:
Do not use oven cleaner to clean
glass.
Clean the glass only when it has cooled to room temperature.
Additives that are put in gas (both natural and propane) to make it smell can be harmful to glass and can
leave a white film deposit on the glass. This deposit can be removed, if cleaned in a timely manner, with
cleaners such as KEL KEM “Polish Plus” (part # 65-06-00455) or comparable product (contact your dealer).
5.10.6
Is my flame performance correct?
Your fireplace has air shutters, dampers, coals, and embers that can be adjusted depending on your fuel and venting
configuration. These adjustments should be made by a qualified technician to achieve the best flame performance. Contact your
installer or Mendota dealer if you feel your fireplace is not burning correctly. Improper setup and adjustment is not covered
under warranty.
5.10.7
What should I do if my fireplace is sooting?
Sooting is caused by improper installation or air shutter operation. However, some small areas of soot deposits on log surfaces
are deemed acceptable. If you observe large soot areas (larger than 1”x1”) on log surfaces or signs of sooting on the door glass
(usually a thin black film on the Fireplace viewing glass or on the outside of the home around the vent cap), the unit must be
immediately turned off and the local Mendota dealer promptly informed. Mendota dealers will correct "sooting" problems, but
Mendota and their dealers are not responsible for damage caused by excessive sooting that has not been immediately brought
to their attention. Troubleshooting soot:
Issue:
Thin black
coating (soot)
forms on
viewing glass.
Possible Causes:
A. Incorrect gas pressure or
burner orifice size.
B. Not enough combustion
air.
C. Leaking glass gasket.
D. Vent system compromised.
E. improper log and/or ember
placement
Corrective Action:
Have gas supplier check for correct gas outlet pressure (3.5" W.C.
Nat. Gas; 10" W.C. LP Gas). Check Orifice Sizes. Check glass gasket
for proper seal. Corners of glass gaskets cannot be bulging out. If
glass gasket along top edge in the middle is white in color across
entire thickness of gasket bulb and gasket adhesive is not
functional, replace glass gasket.
If sooting continues, open air shutter on burner. If sooting
continues, shut off unit and call Mendota service person.
NOTE:
To clean glass - remove glass and wipe glass with cloth or
paper towel.
