Master Forge Gas Grill 5-Burner Model# 678489

Master Forge 5-Burner Gas Grill Model# 678489


The Bottom Line

Of all the store brand grills out there, loaded with features and built big to look impressive, this is the only one made in the United States. Built in Onward Manufacturing's Huntington, IN factory this Master Forge Gas Grill has the same features that make Broil King Grills great but at a smaller price (reduced before it hit stores from $599USD to $499USD). This grill is loaded with features from a full length standard rear mounted rotisserie burner to its cast iron cooking grates, five burners and 10,000 BTU side burner. And while the side burner is underpowered this is an impressive grill for the price.


  • Dual-Tube Stainless Steel burners give even heat front to back
  • Solid construction with durable components
  • Linear flow control values give you great control


  • Comes with a standard rear mounted rotisserie burner but rotisserie kit sold separately
  • Some thin metal body parts
  • Low powered side burner


  • Five 11,000 BTU Dual-Tube 304 stainless steel burners
  • 624 square inches of primary cooking space with a total of 845 square inches
  • 55,000 BTU total output from the main burners
  • 15,000 BTU rear mounted (not infrared) rotisserie burner (rotisserie kit sold separately)
  • Cast iron cooking grates
  • 10,000 BTU brass capped side burner under a flush mounted cover
  • Electronic (AA-battery type) Ignition
  • Cast Aluminum, 304 stainless steel and powder coated steel body parts
  • Propane tank, cover, and rotisserie kit sold separately
  • Made in the USA by Onward Manufacturing Company of Canada

Guide Review - Master Forge 5-Burner Gas Grill Model# 678489 - Discontinued

This model has been discontinued. The closest replacement is the Master Forge 5-Burner Stainless Steel Model# 3218LT

In 2009 Onward Manufacturing Company of Canada bought a factory in Huntington, IN to start turning out a new line of gas grills. Turns out that they are also using this factory to make this Lowe's store brand grill under the Master Forge name. Good news is that this Master Forge Gas Grill has the same great features you find on Broil-King grills at a much more reasonable price. Hopefully this is more than just a fluke and that it will stay on the market and hold at this price.

This grill features a couple of the best features of Broil-King grills. First is the dual-tube stainless steel burners. These specially designed burners create even heating by maintaining constant gas pressure front to back. Something other tubular burners can't do. This grill also has the linear flow control valves that give you great control over temperature.

Packed onto this grill is also a standard side burner, though at 10,000 BTUs it isn't going to produce a lot of heat. Great for warming up a small saucepan or maybe frying a couple of eggs, but it will take a long time to bring a large pot of water to a boil. You also get a full rotisserie system including the spit and forks and a rear mounted 18,000 BTU full width rotisserie burner. This is not an infrared burner, but this one works just as well and isn't as fragile as many of the ceramic IR burners.

One curious note is that this grill has a tag on it saying that it has a new lower price ($499USD), but it never actually sold at the price they say it was reduced from ($599USD). Strange how marketing works isn't it?

Great grill at an unbelievable price, Member tommy_b123

I purchased this grill from Lowe's for $405 on May 29, 2010 and am extremely happy with it so far. (The price was recently reduced from $499 to $449, and I had also obtained a 10% Mover's coupon from Lowe's web site (available to anyone) to get the price down to $405). This is an incredible deal for a grill of this quality. It may not be built like a tank (like a Weber Genesis E310), but the quality is way above your typical grill in the $199 - $399 range. I think it will last many years. The dual-tube burners are fantastic ... all burners start up easily and they provide nice even heat all around. The valve controls are unbelievably smooth and precise. The cast iron grates are heavy duty ... not cheap at all. The flavorizer shields also seem pretty hefty, although this is the first grill that I've had them on. It even has lights built-in to the oven for night grilling, though I haven't tried them yet. I haven't bought a rotisserie motor yet, but the full length rear rotisserie burner looks like it will do a capable job. This is a huge grill, however, and a smaller one may be better suited for a couple or a small family. The primary grill area is about 32"" wide by almost 20"" deep. The one drawback to this is that you lose a lot of heat whenever you open the cover, although it does re-heat pretty quickly. As with most grills these days, the stainless steel used is not the good stuff, so I can't say how long it will continue to maintain a decent appearance. The base steel is thicker than the cheap grills, though. I suppose cleaning it periodically with stainless steel cleaner might help significantly. I have a 13-year old 2-burner Broil Mate (made by the same manufacturer, i.e., Onward Manufacturing Co.), that continues to work well, but this new grill is an incredible step up for me. I highly recommend it.
