greyboy39 Posted February 20, 2018 Report Share Posted February 20, 2018 You are looking at a garage heater vent. i haven't seen this condition in awhile and was hoping someone could clarify the clearacne requirement from the soffit. Im reading 2 feet and 4 feet from different sources. I know its typically up to manufacturers recommendations but just need the general rule of thumb. Thanks in advance!

Mike Lamb Posted February 20, 2018 Report Share Posted February 20, 2018 Generally, at least a foot above the roof line depending upon the pitch of the roof and 8 feet laterally from side walls. I don't think that is going to cut it. Quote Link to comment Share on other sites More sharing options...
John Kogel Posted February 20, 2018 Report Share Posted February 20, 2018 (edited) There is another issue there which is the proximity to the soffit covers which are obviously open. Exhaust fumes are going up into the attic space. How bad is that if the attic is vented? Well, it just ain't right. I had some issues with a similar installation, but a direct vented WH, and the conclusion was that the builder sealed the soffit covers and my client went ahead and bought the place. Just saying, because the proper repair of course is a straight pipe up through the attic to a jack on the roof. For the best answer we need the manufacturer and model number of the heater to get the specs for the exhaust termination.

greyboy39 Posted February 20, 2018 Author Report Share Posted February 20, 2018 Yep that's what I'm referring to, distance from ventilated soffit. The sidewall direct vent is approved but just needs to clear the ventilated soffit by a certain distance. And that's the question that I have. I do not have the model number or make.

Bill Kibbel Posted February 20, 2018 Report Share Posted February 20, 2018 If direct vent, many manufacturers have 18" as the minimum vertical clearance to vented soffits. If mechanical draft, then 4'. The collar is for a roof penetration, not a wall. The cap is probably for vertical termination only. Quote Link to comment Share on other sites More sharing options...
Trent Tarter Posted February 21, 2018 Report Share Posted February 21, 2018 Looks like a DIY install. Is the gas heater even approved for direct venting. Quote Link to comment Share on other sites More sharing options...
RK52 Posted April 3, 2018 Report Share Posted April 3, 2018 Seems to me the rain water deflection provided by the hood isn't going to work too well at the horizontal.... Quote Link to comment Share on other sites More sharing options...
