Topic Title: Too Hot! BH-421-SG-2 The Classic

I got lucky and picked up a classic Classic at a yard sale last month. I tried to talk the owner out of selling it, but he didn't know what he had. He picked it up as payment for some yard work he had done, and needed the money. The first thing I did was disassemble it, cleaned it and reassembled it using 304 stainless steel bolts, cleaned the burner, adjusted the flame for blue with yellow tipping, and replaced the leaking regulator with a GrillPro low pressure type 1, 11 inches WC. Now, my problem When I preheat, I get a temperature of 600 degrees F with no food. I just did a load of wings (4th of July, ya know) and they wanted to cook hot, around 475. I checked my orifice (Holland recommends #55) and surprisingly found a #56. I checked my thermometer and it is OK. As you know, the higher the wire size, the smaller the hole, and the colder the grill. On my 2nd load of wings, I added about 1-1/2 pint of water to the drip pan, and this lowered the temp to about 425. My question, has anyone else had a Holland that ran hot, and how did you deal with it.

The orifice size & the regulator pressure are the 2 main keys. Have you actually checked the orifice size with a gage? How do you know some previous owner didn't drill it out oversize?

Are all the internal parts original or later model replacements? Newer drip pans & flame deflectors pass the heat through better & will cause the grill to get hotter than originally designed for.

Hose/regulators are calibrated to a +- tolerance. If you have an oversize orifice, a hose/regulator that might be calibrated on the high side, plus newer stainless or aluminum parts inside, you have perfect storm for an overheating grill.

Get it fixed. It won't last long at those temps.

Hi Tracy, yes, I went down to my local full service Ace Hardware/Plumbing and Heating Company, and we both checked it with wire gauges. We agreed that it was a #56 orifice, not the hotter #55. For your question, are all the internal parts original or later model replacements? I don't know. Everything appears to fit as if it were original, with the appropriate amount of use. The exterior shell is immaculate, and I believe the grill was garaged and lightly used during it's life.
Does anyone suggest going to the next higher size orifice? Or any thoughts. Thanks to Tracy for your response.

Go to the "Parts" page on the web-site. Click on one of the stainless steel models, then "Gas components". A #57 orifice is standard for a stainless grill on LP.

The orifices are $3.00 plus shipping. Also, if you order, consider ordering some seasoning or wood pellets for smoking to help ease the pain of the minimum shipping charge.

Thanks for the good advice, Tracy. Got my #57 orifice and I adjusted my air shutter to blue. It's dropped my temp to about 500F on the grate. I'm going to play around with the air/gas mix to see if I can cool it off another 75F or so. Also used your advice about the S/H and bought a couple chimneys with the rounded top, not flat like pictured on the manual. This should help with the grill cover hanging up. Best regards!

The air-shutter is not intended to be used for temperature adjustment, only for obtaining the correct gas/air mixture that won't blow out & will burn cleanly. Blue flame with yellow tips, then don't mess with it.
Since you have never mentioned your actual model number, I am beginning to think you might actually have a BH421SS-1 Premier, not a BH421SG-2 Classic. The #56 orifice you originally found in it would have been oversize for that model. Is the grill black or does it have stainless steel top & bottom shells. Is the drip pan steel or aluminum & is the flame deflector above the burner mild steel or stainless steel? They all affect the heat.

Hi Tracy, the model # on the grill data plate says BH-421-SG-2, but since I bought it at a yard sale, I don't know it has ever been repaired or refurbished. It's black, but I'll have to get back to on the deflector and drip pan. Got a drunk chicken cooking right now.
