UVS27 Vent-Free Gas Heater

Maintenance

The following procedures will help ensure that your heater continues to perform safely and efficiently.

Firebox Cleaning and Inspection

Cleanliness is critical to correct operation of the heater. The log set, burner, valve controls and air circulation areas must all be kept free of dust and unobstructed by debris. Inspect these areas before each use and clean whenever accumulation is evi- dent. Follow the simple procedure outlined below.

Frequent cleaning may be necessary in living environ- ments subject to excessive carpet lint or pet hair. For example, if you live with a dog that sheds continuously, you will need to inspect the burner area frequently and clean it as often as the accumulation requires. In ex- treme conditions, it may be necessary to clean the burner and log set monthly or bi-weekly.

This appliance should be inspected and thoroughly cleaned annually by a qualified gas technician.

Cleaning Procedure

1.Turn the burner OFF and let the heater cool com- pletely before cleaning.

2.Lift the Front plate up and then swing the bottom out to disengage it from the heater shell. (Page 13, Fig. 19)

3.Remove the screen by lifting up and away from the unit. Or, if so equipped, remove the glass panel by rotating the two cams toward the front of the firebox. Lift the panel up and off of the firebox frame. (Fig. 28)

4.Carefully inspect the log set for damage. Contact your local dealer if any damage is evident. DO NOT

OPERATE THE HEATER WITH A DAMAGED OR LOOSE LOG SET.

Use a soft-bristled brush vacuum cleaner attachment to remove dust or debris from the log set, pilot and burner. Use care as the log set is fragile.

5.Inspect the catalytic combustor at the top of the firebox. Replace the combustor if any damage or deterioration is evident.

6.Replace the screen or glass panel and the front plate. DO NOT OPERATE THE HEATER WITH

THE SCREEN / GLASS PANEL OR FRONT PLATE REMOVED.

Glass Replacement

If so equipped, do not operate this appliance with the glass panel cracked, broken, or removed. Replace damaged glass only with an approved CFM Corporation ceramic glass panel. Follow the Cleaning Procedure instructions regarding parts removal.

Care of Cast Iron

An occasional dusting with a dry rag will help keep the painted surfaces looking new. Use high-temperature stove paints, available through your local dealer, to touch-up areas as needed. Clean areas to be painted with a wire brush and be sure to cover the log set, burner and valve assembly. Apply the paint sparingly; two light coats of paint will give better results than a single heavy coat.

Porcelain enamel surfaces should be cleaned with a soft, damp cloth. Do not use abrasive cleaning agents. If necessary, use only a cleaning agent formu- lated specifically for use on porcelain enamel surfaces.

WARNING

Turn the burner Pilot OFF before applying paint. NEVER paint pilot or around pilot area.

WARNING

Dust and debris accumulation can result in poor performance. Inspect the Valve compartment, burner parts and log set frequently and Clean these parts monthly or as often as accumula- tion warrants.
