Heil Gas Furnace Filters

I have an older Heil gas furnace, I need to replace the filters, but have no idea where they go. I know here are two, and that they sit at an angle, but can't remember how to access the place they belong.

    That was helpful, thanks. I didn't realize the top door was a "door", and could be removed.
    Thank you!

The filters will go by your blower compartment remove the doors at the furnace and look where the sheet metal opening meets the furnace

How often should filters be replaced on a Heil Ultimate II gas furnace? Once at the beginning of the "heating" season and once at the end - would that be sufficient?

Hello, it depends what type of filters you are using, if you have the pleated filters such as the 3m brand they should be changed every three months If you are using the blue filters they should be changed every month.

We recently purchased a home with a heil furnace and I need to know what size filter it requires. It is a gas heil model # NUG1075DF01. Please help !

That is hard to answer but I would say that for a furnace of that size you are probably looking at somewhere around 16x20x1. On older heil furnaces they often had the filter mounted inside the blower compartment so if the case you can just remove the cover and measure it. If not it should be located on the return air duct close to the furnace. Hope this helps you some. Thank you.

Where do the filters go in HEIL gas furnace Mfg# 697A

Hi, If this is a split system, look in the indoor unit to see if it is at the top, or bottom. This depends on if its a down flow or up flow unit. Sometimes they are in the hallway ceiling behind a grill that drops down. Walk through your home and look up for a grill. Look near the furnace down low also, they will put them in lots of places, but usually near the furnace. If no grill any where, it will have to go inside above or below the blower motor. You should see the opening where it lays with the arrow on the filter pointing in the direction of the air flow. If you have no grill, and there is not one in the furnace, you need to put one where the air is coming back to the unit inside to catch the dust. Please let me know if you found it and please rate me on this as I know you will be kind.

I have an older model heil quaker natural gas furnace. the wiring to the blower limit switch has dry rot and melted thru causing a short. is this common? can i just rewire or may there be other problems

Test to make sure the limit switch is still working prior to the rewire. Use an Ohm meter and test for continuity. If good, use some good quality 14 or 12 guage wire to rewire. If the unit has an in-line fuse, you will need to replace that as well.
