General Glass Information
Glass Cleaning
It will be necessary to clean the glass periodically. During start-
up, condensation, which is normal, forms on the inside of the
glass and causes dust, lint etc. to cling to the glass surface.
Also, initial paint curing can deposit a slight film on the glass. It
is therefore recommended that initially the glass be cleaned two
or three times with non-abrasive common household glass
cleansers and warm water. After that, the glass should be
cleaned two or three times a season depending on the circum-
stances.
Glass Replacement
REPLACEMENT GLASS FOR BOTH VENTED UNITS
Model Series ZV3600 or ZV4200 can use either tempered glass
or Robax ceramic or coated Neaoceram glass. Must be 5mm
thick.
To replace glass, clean all materials from door frame. Scrape off
old silicone down to metal. Using a high heat silicone (tempera-
ture-resistant to 500°F (260°C) apply a continuous bead of
approximately 1/32” to all four sides of frame and insert glass
with new gasket. Frame should be on flat surface, with a small
amount of weight pressing glass into silicone. Let dry approxi-
mately 15 to 20 minutes. The door can be re-installed by revers-
ing Steps 1 & 2. Use caution when removing broken glass,
wear gloves.
Removal of the Glass Door
1. Remove the two screws located behind upper grill or unfasten
latches if so equipped.
2. To remove, pull frame forward and lift from bottom door retain-
er channel.
Confirming Proper Venting of Appliance
To check for proper drafting, use this procedure.
1. Place unit in operation and let run for approx.1 minute to establish up a draft.
2. Open top grill area to expose the draft hood.
3. Using a match or something that will produce smoke, place it up to the opening of the draft
hood and verify that the flame or smoke is being drawn into the draft hood. If the flame or
smoke is blown away from the draft hood opening, you may have to re-check the venting and
verify that there is a minimum of 12 foot of venting or check the house for negative pressure.
If there is negative pressure, you will have to bring fresh air to the unit.
