Hi all…
I have a MEMCO boiler that is direct vented and unfortunately the website for MEMCO is not much help… I am looking for some guidance on the location of the direct vent. Currently directly below a door and steps. Everything tells me it is wrong… but I was looking for some reinforcement. Is there some general guidance for direct vent installation? Outside of manufacturers installation…
I’ve seen somewhere some diagrams of “recommended clearnaces”… any help would be appreciated.
