6.Installation and repair should be done by a qualified service person.

7.To prevent malfunction and/or sooting, an unvented gas heater should be cleaned before use and at least annually by a professional service person. More fre- quent cleaning may be required due to excessive lint from carpeting, bedding material, etc. It is imperative that control compartments, burners and circulating air passageways be kept clean.

In addition, the smoke and/or aromatics (scents) may be reburnt in the vent-free appliance which can produce odors. It is recommended to minimize the use of candles, incense, etc. while the vent-free appliance is in operation.
