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.
Warning and Cautions.
• Do not clean when the glass is hot.
• Do not use abrasive cleaners.
• Using a substitute glass will void all product
warranties.
• Do not strike or abuse glass. Care must be
taken to avoid breakage of the glass.
• Do not operate this fireplace without the glass
front or with a broken glass.
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.
A Fresh Air Kit may be required by some building codes, remove cover plate on the bottom side of
unit and insert three inch flex duct into the side of fireplace by screwing it into the hole provided,
attach the other end to the plastic wall vent. When possible place the plastic vent below the bot-
tom of the fireplace
