Please note this is the KEYSTOKER tag with your unit number located on the back of the unit.
On chimney models, rice, buckwheat, or a mixture of both.
For direct vent stoves if the stove is going against an outside wall above outside grade, a rear vent is best. If below grade, a top vent will allow you to get to an outside wall.
A Keystoker designed direct vent system is mounted directly on the stove and never comes in contact with moisture, thus expanding the life time of the motor and fan blade. The blade or a direct vent is a flat radial blade which doesn’t collect dust and cleaning maintenance is needed sparingly. Keystoker direct vent systems or stoves do not require a barometric damper.
2. The higher CFM blower will remove more heat from the stove, which will lower the temperature of heated gases going up the chimney, thereby increasing the efficiency of your stove.
Direct vent models include wall kit:
1—4X18″ stainless pipe 1—12X6″ black pipe 2—wall plates
1—4″ stainless tee 1— stainless steel rain cap
|Feed||1 ¼”||1 ½”||2″||2″||2″||2″||3″||3″|
|Return||1 ¼”||1 ½”||2″||1 ½”||2″||2″||2″||2″|
2. Installing a loop will prevent boiler shock. When circulator runs cooler water from return, the line will not all dump into boiler. Some of the cooler return water will flow through loop and mix with heated water in supply line. This will allow circulator to run for a longer period which is especially important in large heating loads or for homes with radiators.
3. If timer is running too long, or if coal feed adjustment is set too high, water will be overheated. If water temperature reaches temperature setting of 4006B (recommended setting is 220), circulator will turn on to reduce boiler temperature. Cooler water from return line will be forced through loop to cool water quickly (approximately 10 to 15 seconds). This will lessen the likelihood of overheating the entire heating system.
