1. Fig 23 Fig 24 Rotate Latch A 3 month cleaning will give you a base line as to how often your DVC500 needs to be cleaned Cleaning intervals will differ in each installation because of the ash and moisture content of the coal and the amount of coal burned NOTE Unit should be off amp cooled down enough to perform these maintenance items 1 Remove Ash Pan then remove ash shield behind Ash Pan fig 22 Lift the shield up and forward in order to remove it from the stove This will expose the Blower Cover and Latch fig 23 2 Rotate the Latch counterclockwise to the vertical position as shown in fig 24 3 Remove the Blower Cover by tilting the left side slightly forward Next slide the Cover left and out of the slot that holds the right side in place The Cover can now be removed to expose the Draft Blower Wheel and Exhaust Outlet fig 25 4 The blower wheel blower housing and exhaust outlet can now be cleaned with a brush and vac uum cleaner NOTE The ESP probe is located at the rear of the exhaust outlet shown in fig 28 Be careful not to damage the probe when clean ing 5 Open the Fines Cover on the bottom of the feeder under the grates and clean see fig 26 ATTEN TION MAKE SURE COVER IS CLOSED AND TIGHTENED2. especially if the hopper lid is open or leaking The TCP senses the temperature of the feeder and feeds coal if the temperature rises too much This prevents the fire from reaching the coal in the hopper Red Ash Coal may form klinkers fused together ash which may cause grate blockage in severe cases Anthracite Coal can be purchased in bags or in bulk If you buy in bulk try to have the coal delivered before temperatures reach the freezing level This is because salt may be added to the coal to keep it from freezing on the truck This will not affect burning but will promote rust and corrosion Some Coal Companies wash their coal better than others to remove fines and dirt This makes air flow through the coal better and produces less fly ash Whether bagged or in bulk the coal must be dry before loading it into the stove At a minimum open bags a few days in advance to allow drying Buy your bulk coal mid summer to allow plenty of time for drying Good clean White Ash Coal is the fuel of choice however Red Ash Coal will also burn well As long as it is Anthracite 23 24 Grate System Assembly Or Replacement grate Insert The DVC500 grate system is composed Fig 29 of four pieces the grate holder 2 63 hole grate inserts and grate angle The grate angle is bolted to the grate holder with 2 3 8 x 1 1 4 bolts Before installing the grate holder 3 8 grate angle round gasket must be checked in the gr

This 15 because there Is lower voltage flowing to the draft motor As ashes build up the light will get brighter because the draft motor needs to run faster in order to maintain the negative pressure in the firebox When the indicator light for the draft motor appears as bright as the rest of the lights it is a good indication that it s time to clean the appliance and the venting If the circuit board is flowing full line voltage to the Draft Motor and the negative pressure in the firebox is too low the following safety protocol will begin Stage 1 When the safety switch senses a loss of negative pressure in the firebox for more than 68 seconds the following happens The combustion blower will reduce in speed During this cool down period the feeder is allowed to opreate If needed the feeder can opreate for up to 3 minutes After 72 minutes if the safety switch has not sensed another pressure loss the unit will automatically go back to the control board setting If the safety switch senses a loss of negative pres sure anytime during the STAGE Protocol the unit automatically goes to the STAGE 2 Protocol Stage 2 If Stage 1 has already begun and the negative pres sure is lost The status light will start to blink 2 blinks The combustion blower and feeder motor will shut off These motors will remain off for a 5 minute cool down period After five minutes those components will restart at a reduced feed rate 3

When to use Stove Temp Mode In Stove Temp Mode the control will regulate the fire to match a constant exhaust temperature based on the 1 thru 7 settings on the inner portion of the temp dial Heat output and fuel consumption will remain constant This makes it possible to tell how long a hopper full of coal will last The distri bution blower speed can be varied according to the position of the mode selector between low and high fig 16 When to use Room Temp Mode In Room Temp Mode heat output is controlled automatically by use of the Room Sensing Probe When the Room Sensing Probe calls for heat the stove will increase output When the Room Sens ing Probe is getting close to the set temperature the stove will begin to level off output and keep the fire burning at just the right temperature to maintain that setting If the temperature in the room exceeds the set point the stove will idle on a low burn until more heat is needed High output is determined by the Feed Rate The maximum Feed Rate should be set for 1 to 2 of ash in front of the fire In Room Temp Mode fuel consumption is sacrificed for exact room temperature Therefore as it gets colder more coal will be burned automati cally The distribution blower speed can be varied according to the position of the mode selector 18 DAILY MAINTENANCE Fig 18 Ash Out Position If the feed adjuster is left in the Ash Out position the fire wi
