Keystoker Koker

Thanks Len.

Sorry im sitting at work, without the manual, think about everything that needs done when i get home. Some of this might be covered in it but thought i would ask.

Should the horizontal run of the 4" stove pipe be at an angle?

Anyone know how many amps the koker is rated at (with direct vent)? Instead of running a dedicated electric line i was going to use the dedicated electric line my water heater uses. Its a propane water heater only using a small direct vent exhaust motor on the water heater.

I'm not an electrician but my understanding is the hot water heater and the Koker need to be on dedicated (separate) circuits to meet code. I suspect that they would work fine if you put them on the same circuit but you're not supposed to.

My vent pipe is pretty close to horizontal. I don't think a slight angle would be a problem since the vent motor is pushing the exhaust along.

Yea that was my thinking too but i`ll keep them happy and run a new line...no worries for down the road

I agree and now is the time to do it.

I have my supply duct figured out...just waiting for some parts. I had a question about the return duct. Would a 12x12 return duct to one side of the blower be big enough? and blocking off the other side. The supply will be 18x8.

I would not block off one side of the blower motor.
I ran 10" dia. ducts to both sides.
You could build a box around your blower and run your single 12x12 duct into that so that both sides are pulling from it. It's important to pull as much air down to the blower as you can.
You could leave one side of the motor open and pull air from the basement but that would be the path of least resistance and would reduce the amount of air you pull directly from upstairs thru the 12x12 duct.

I have both sides of my return filtered one for the cold air return duct & the other pulls from the basement, have had no problems I think it's better to have plenty of air.

I have a koker and I did block off one side of the blower. Been running like that now for two years with no issues. I also use a Merv 8 pleated filter and save money by only having to use one filter. Best I can tell the blower is not any hotter running with only one side and the Merv 8 pleated filter.
