I have this KAZ DT-70 series and I can't get the grill off to clean the blades. Can you help me please.

I picked up a Sunbeam Humidifier model 1118 for $7 (which was $7 too much) second hand. It wasn't until I got home that I noticed it was filthy-dirty inside...(dirtier than shown in the photos) the reservoir, the bottom tray, AND the fan chamber all needed major cleaning.

A quick Google search told me that the grill is "not removable", and the unit is "not user serviceable". Companies do this/say this for two reasons:

a) They want you to throw it away and buy a new one, landfills and plastic filling our oceans be darned
b) They want to protect themselves from lawsuits, should someone injure themselves servicing their product (or in this instance, cutting their fingers off on the fan blade).

Imagine if all of that design know-how was put into making the product serviceable, cleanable, and long-lasting, rather than ensuring it can't be opened or repaired by the average joe.

Me, I've opened and repaired enough gadgets to think differently.

You CAN remove the grille.
Carefully insert a series of flat-head screwdrivers between the grill and the body a few inches apart, wedging the grill edge away from the body.
There are slits in the body (see photos) that will allow you to get under the grill edge and pry it right out when enough of it has been detached from the anchoring groove.
But be gentle while you're doing it.
The Grille is plastic and flexible; it will bend, but if you use too much force you will damage either the grill or the body.

The photos also show how the grill is anchored to the body - via a groove in the grille edge.

You can put the grille back after cleaning the blades and fan chamber much the same way; pressing down, and if required: prying the side of the grill inwards with a flat head screwdriver.
Mine snapped right back into place with a bit of downward pressure.

Yes there is an adjustment on the air shutter control valve. Which is part of the burner system. It will look like the blades on a fan. It should be set at 3/4's of the way open. But, before you jump on that, yellow flames are also an indication that you're running out of gas or the venturi valves on the burner are clogged. Spiders love to build nest in them.. So check you tank.and the Venturi Valves first.

To assist you further, I have provided a link to the Owner's Manual for the new P3 Series grill. It is almost identical to yours, unless you have the new model. In which case it will be identical.

Hope this helped you to troubleshoot and solve the problem. Please let me know and Happy Grilling.

Unfortunately, the D4 series grill hasn't been around since Martin Industries went bankrupt 8 years ago and Empire Comfort Systems to over Broilmaster. However, today's 'P' or Premium Series is the closest to the old D4 series, as far as burners and burner installation and removal is concerned.

I have included a link to the Owners Manual, which shows how to assemble the grill and install the burner(s). Just do the burner installation in reverse. You can download and print the manual for future reference.

Here is the owner's manual:

It says first to unplug the unit.

While pressing on the two notches along the front of the grille, pull the grille toward you and remove it.

Gently pull down on the top filter frame and pull forward.

Remove the protective wrap from the filter.

Place back into the air purifier housing and snap filter grille into place.

I want to clean the white gritty minerals from the fly wheel inside the humidifier. I took the three screws out but the plastic wheel will not move. I'm afraid to force it...might crack or break.

There are three clips the hold the grill to the cowl.
Look along the back, outer edge of the fan.
One clip at 11 o'clock, one at 2 o'clock and one at 6 o'clock.
Use a flat blade screw driver to push the 11 and 2 positions down (do 11 then do 2) and the grill should come off. The blade just pulls off. It only goes on one way (due the the "D" shaped shaft).

You will need to take this apart and use a good degeasing spray to remove off al the dirt. Use diesel/kerosene to wash well and clean it dry. Use a good paintt brush to wash off all dirt into the hidden areas.
Wipe dry finally to reset.

It's similar to the 600 and 700 series based on a picture of those compared to the 280b model I have. http://www.vornado.com/product-support/support/faq.aspx

I used a can of compressed air to clean my fan blades and this did the job. I bought a 6-pack of 3M Dust Remover at Sams Club to save money. Hope this helps.
