Majestic fireplace

[kurt]

Today's job had one of those creepy gas fireplaces w/ceramic logs & glass on 3 sides & a wood top; the thing stuck out into the room like a kitchen counter peninsula.

It's on an interior wall; the vent goes up, turns 90 degrees into the adjacent stud cavity, takes another 90 vertical about 9 feet, takes another 90 & goes about 14 feet to vent out the sidewall @ the 2nd story rim joist. The only part of the vent I could see was the outlet; all the pipe is buried in the wall & ceiling. The vent outlet looks like standard direct vent 3" pipe.

I've been to the Majestic website, but can't find model #360DVS3 RN; they don't seem to make it, which is odd because this house is brand new.

My concern is the length of vent & all the bends; this is a development by a bunch of Russians that don't seem to know squat about anything else, so I'm thinking the vent may be another of their improvisations.

Anyone got any good ideas, or know how to find something @ the Majestic website, 'cuz I can't seem to.

Russians installing Chinese fireplaces, no, it doesn't sound safe.

Hi Kurt,

I think the rule for vents applies here. Nothing more than 45° but one up to 60°.

Go to http://recalls.gov and see if Majestic recalled that model. I seem to recall that Majestic has a recall within the past couple of years.

Let us know what you find.

ONE TEAM - ONE FIGHT!!!

Hey Kurt,

If it's a Type B vent there are limits to the length of "developed" horizontal distance. Not sure if it's spelled out in IRC but in IMC it surely is. It may be pegged to the BTU rating of the appliance. If developed length is over spec for natural draft, then accessible powered assist is needed.

Homenspector, that's funny [:-eyebrow

No recall; good thought though.

A guy (Rich Farrell) on the ASHI board found it @ the Vermont Castings site; don't know why I couldn't.

It can have a couple 90's (surprising)& exit within 36" of the appliance, or (even more surprising) can go 20' horizontal but has to have a minimum 7.5' vertical rise in that run. IOW, there has to be a substantial upward slope on the pipe. I don't think this one is going to make it.
