ADJUSTING THE VENTURIES:

•Remove the ash shelf by undoing the screw at each end, pull shelf towards you.

•Remove one screw from the cover plate located below the ash shelf. Loosen the other screw (do not remove) swing the cover plate out of the way and tighten screw down to hold it in place.

•With along screwdriver rotate spring clips to open or close the shutter to the desired setting.

The venturies allows the amount of air coming into the fireplace

to be adjusted in order to accommodate different climates and venting arrangements. Start the pilot and then the burner. Make

sure the pilot flame is burning normally and none of the burner ports are plugged. Let the fireplace burn for roughly fifteen minutes and then examine the flames, compare the flames to Figure 46.

The ideal flame will be blue at the base and light orange above. The flames should be of medium height. If the flames look like this, no venturi adjustment is needed. If the flames are fairly short and mostly blue, the fireplace is getting too much air. Therefore, the venturies should be closed slightly until the correct flames are achieved. Flames that are very orange, with tall, dark, stringy

Maintenance and Service

Periodically check to ensure that your direct vent system is clean.

Periodically check the pilot and burner. Check to see that all the burner ports are clean and clear. Check the pilot head for blockage. Check to ensure the pilot flame is blue with no or very small yellow tips.

OPENING THE DOOR:

Turn unit off and wait until the appliance has cooled down.

1.Open the right hand hinged side flap, which will expose a door fastener. Using a 1⁄2” wrench, loosen the fastener.

3.If the door must be removed open the door and lift the door pins out of the hinges (see figure 6).

4.Ensure the door is properly fastened after cleaning before attempting to re-light the appliance.

CLEANING THE GLASS:

Figure 6: Removing the Door.

Allow the glass to cool before cleaning. It will be necessary to clean the ceramic glass periodically. During a cold start up, condensation will sometimes form on the glass. This is a normal condition with all gas fireplaces and stoves. However, this condensation can allow dust and lint to cling to the glass surface. Initial paint curing of the appliance can leave behind a slight film on the glass. This is a temporary problem. It is therefore recommended that the glass be cleaned initially after about the first four hour of use. Depending upon the amount of use, cleaning should be required no more than two or three times per season. To clean the door, use a mild glass cleaner and a soft cloth or a glass cleaner available from your Enviro dealer. Abrasive cleaners will damage the glass.

TO REPLACE DOOR:

The glass in this appliance is an integral part of the door assembly. If the glass is damaged or broken a replacement inner door with glass assembly must be purchased.

The glass in this appliance is ceramic. If the glass is damaged or broken a factory door with glass replacement must be used.

Remove the door with glass, a new door assembly must be purchased from an ENVIRO dealer (part #: EG28-103). Do not use a substitute materials; it will void the warranty.

CLEANING THE INSIDE OF THE FIREBOX:

1.Turn off the unit and allow it to cool down completely.

2.Remove the logs carefully from the firebox. Gently remove the embers and place on a piece of paper towel, until ready to replace.

3.Vacuum the bottom of the firebox thoroughly. Carefully clean off any dust on the logs and remove any lint from the main burner and pilot burner.
