INSTALLATION AND OPERATION MANUAL

MF3700, MF3800 Models

no proof of fire push on to start

This means the stove went through the starting fire or electric ignition sequences and did not heat up enough to satify the proof of fire switch. Press ON button and restart the fire. Note: There may be fuel burning in the stove while it shows this screen. Use extreme caution when manually relighting a hot stove.

vacuum fault check seals

This means that the stove doesn’t have enough vacuum in the firebox to run safely. Check that the fire box door is closed and that the seal is in good working condition. Check the ash pan door to make sure that the ash pan is firmly seated and that the seal is in good working condition. To clear this fault screen press the OFF button. If all doors are closed and sealed properly and the problem persists please call your dealer or CSW customer service for advanced trouble shooting.

loss of fire off to reset

This means that the stove has cooled to a point where it is no longer heating the room. Make sure that the hopper has fuel and that there are no obstructions that prevent fuel from entering the firepot. Pressing the off button will send the program to the STARTING FIRE (MF3700) or ELECTRIC IGNITE (MF3800) screen. Pressing the SCROLL button will send the program to the FUEL RANGE screen.

STOVE SHUTDOWN

To shut down stove operation press the OFF button at anytime. This will cause the stove to stop feeding fuel into the firepot, yet the combustion blower will continue to run exhausting all smoke until stove is off. When the stove runs out of fuel it will safely shut down automatically.

IMPORTANT: NEVER UNPLUG YOUR STOVE WHILE THERE IS FUEL BURNING IN THE STOVE.

Doing so will cause combustion blower to stop and smoke will enter the room through air intake holes.

NORMAL CARE & MAINTENANCE

CLEANING THE GLASS

Only clean glass when the glass is cool. Wipe the glass clean with a dry or damp rag. If this does not clean the glass use any non-abrasive liquid spray.

REMOVAL OF BROKEN CERAMIC GLASS

Open the door and lift it from the hinges. Lay the door down on newspaper with glass clips facing you. Loosen the screws and take off the glass clips. Remove the broken glass carefully and discard.

Reverse the above procedure for replacing new glass with new gasket.

FIRE POT REMAINS

Every time the hopper is filled with fuel the firepot should be emptied. To empty the firepot pull out and push in on the firepot cleaning rod. See figure 25. THE FIREPOT MUST BE PUSHED ALL THE WAY BACK AND SEATED AGAINST THE POTHOLDER FOR THE STOVE TO FUNCTION CORRECTLY.

SOOT AND FLY ASH

The products of combustion will contain small particles of fly ash. The fly ash and soot will collect in the exhaust venting system and restrict the flow of flue gasses. The exhaust venting system should be inspected at least once per month to determine if cleaning is necessary. If cleaning is necessary disassemble the exhaust vent and clean the individual parts.

DISPOSAL OF ASHES

Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground, well away from all combustible materials, pending final disposal.

EXHAUST AND CONVECTION AIR FILTER

Clean air filter (730008) regularly, replace if needed. See figure 24.

DAILY MAINTENANCE

The surfaces on the stove may be hot. Always wear protective gloves even when the stove is cool to the touch.

•Clean the glass only when it is cool to the touch using any non-abrasive cleaner.

•After one hopper of fuel is consumed, the fire pot cleaning rod should be cycled (pulled out and pushed in) to drop the ashes into the ash pan.
