I got to do some seasonal maintenance on a couple of Aerco Modulex mod-cons today. If you get a chance to get your hands into one, I fully recommend you check out what some next-level engineering looks like. Each section has its own burner, gas valve, draft inducer, ignitor, and flame rectification rod. The redundancy means incredible turndown (39:1 on some models) and no emergency breakdowns.

Never seen one of those. Worked on a few of the larger Aerco's changed a HX on one.
Why no drip leg on the gas? Is that the NY thing about not being able to steal gas off the drip?0 -
Exactly. NYC got funny about drip legs for a while there. Now inspectors are saying it's got to be listed in the equipment manual as a necessity and only after the appliance valve.EBEBRATT-Ed said:Never seen one of those. Worked on a few of the larger Aerco's changed a HX on one.

@JohnNY
I remembered a post here years ago about someone running a water hose off a drip leg to get gas to the building next door.
Never herd of a drip led after an appliance valve......that's a new one. I always thought the purpose was to keep junk out of appliance valves!!!!!. I know around here they don't allow drip legs outdoors.0 -

@Alan (California Radiant) Forbes
here too in the old days. Now they claim that the gas is a lort "drier" than it used to be so I don't see then as much. Not sure when the code changed0 -
No, by “appliance valve” I mean the gas shut off valve. It’s still far from foolproof.Contact John "JohnNY" Cataneo, NYC Master Plumber, Lic 1784

They had Arcos at the college I worked at. They were reliable but improper application as they return water temp was normally over 140f for makeup air reheat coil.I agree it’s a cool design. ButThey required the gaskets between the sections replaced every 3 years.0
