Newbie... Need Install Advice For Farenheit Endurance

I live Solar gain. No stoves at all today. Wife shut down the Enerzone at 7am and when I got home this evening, it was 77° in the house!!

I love this warm weather. We almost hit 50° today. I can't wait till Wed/Thurs this week. Supposed to be right near 60°. It's a "warm" welcome (pun intended )

 

There are several key areas that need cleaned. The obvious is the firebox and ash pan area. The firebox and all passages should be as close to 100% free of ash as you can.

1.) The back wall of the firebox is hollow. So a brush needs stuck up the back of it, until it comes out by the heat exchange tubes up top.

2.)Remove the small rectangular clean out plate above the heat exchange tubes and clean the tubes extremely well.A long bristled brush works well for this, or compressed air (make sure you have a leaf blower hooked to your vent outside if using air)

3.) The exhaust path behind your ash pan (one hole on new units, two holes on older units) A long lint brush or what's called a coil brush (cleaning a refrigerator coil)

4.)Remove the Clean out plate that is on the lower left side of furnace (exhaust path that leads the exhaust manifold.) And scrub and vac it out really good. Coil/lint brush here as well.

5.) I only remove my combustion blower every other year. But I only burn between 1.5 to 2 ton in my furnace every year. Cleaning the impeller on the combustion blower should be done yearly if you have burned a substantial amount of fuel. My unit does not have an inspection plate. But I heard the new ones may? If your's has this? You are a lucky man!! To remove the blower on mine. You have to break the seal on the vent to the snout on the furnace, then remove the entire exhaust manifold, and finally remove the motor/impeller assembly.

6.) Clean vent and termination cap.

I normally have my leaf blower running the entire time I am cleaning the furnace.

And after I clean the inside of the furnace, I spray Pam Cooking Spray over the inside of the firebox, heat exchange tubes, ash pan area, ash pan, etc. This will help keep surface rust to a minimum.

I will try and take pics to better describe where these places may be. If my description is not good enough.

The gaskets on these furnaces are pretty tough (foil backed on one side) but sometimes you're not so lucky. There are 4 gaskets total that you may need to replace. Only 2 gaskets if you have the inspection plate on the exhaust blower)

Hope this helps..

 

What comes off when you remove those 4 bolts?

Is that the elusive inspection cover I have heard of?

 

Yes. Very different

This is an updated version for my furnace. The old one was even more restrictive than this one.

I will get pics of the old manifold tomorrow and pics of all the other places I spoke of above.

 

I believe Ward8512 is the only other one with a new unit like yours. But she just got hers last year and has gone through a lot since then. So I am unsure as to whether she looked behind there or not?
