DV400S DIRECT VENT ROOM HEATER

MAINTENANCE INSTRUCTIONS

Cleaning the burner and control compartment

Keep the burner compartment clean. Brush this area with a clean, dry paint brush and vacuum at least once a year. Always turn off the gas valve and ON/OFF switch before cleaning.

Checking flame patterns

Visually check the flame of the burner periodically, making sure the flames are steady; not lifting or floating. The flame color should be blue with yellow tips. The thermopile tip should be covered with flame. See Figure 26

NOTE: If the air shutter is open all the way and the flames remain sooty, shut off gas to the appliance and contact a qualified gas service technician.

If the vent configuration is installed incorrectly, the vent may cause the flames inside the appliance to lift or “ghost” - a dangerous situation. Inspect the flames after installation to ensure proper perfor- mance. If the vent configuration is correct, yet the flames are lifting or ghosting, shut off gas to the appliance and contact a qualified service techni- cian. ( See Fig. 27)

Venting system inspection

The heater and venting system should be inspected before use each season, and at least annually, by a qualified field service person, to ensure that the flow of combustion and ventilation air is not obstructed.

Cleaning the glass

It is recommended to wear gloves while handling or removing the glass. DO NOT REMOVE THE GLASS WHEN HOT.

Note: When cleaning the glass, NEVER use abrasive materials. NEVER clean glass when hot.

To clean the glass, use a non-abrasive, mild cleaning solution. (For example, a glass cleaner for stubborn film, or an oven cleaner.) Apply an adequate amount to the glass and wipe off with a damp cloth. Be sure all cleaner is thoroughly rinsed from the glass.

Never operate this heater without the glass properly secured in place or if the glass is broken.

In the event of glass breakage, follow door removal instruc- tions. This will allow the removal of all glass fragments and sheet metal edge protection strips. Vacuum all remaining glass pieces with a shop vac. (DO NOT VACUUM IF PIECES ARE HOT.) Replacement glass can be ordered through your local dealer or distributor. Never use substitute material. Only ceramic glass may be used on this heater.

Log cleaning

Carbon build-up can be removed with a vacuum cleaner.

WARNING!

Do not use this heater if any part has been under water. Immediately call a qualified service techni- cian to inspect the heater and to replace any part of the control system and any gas control which has been under water.
