Re: Recognize This Air Vent?
That's a Hoffman #74 vent. Not right for a Main vent anyway. The #74 is designed as a steam heater vent. The #75 is the correct vent for a main but it is probably way to small for the average Main.What's a "Steam heater vent" ???

Re: Microamp readings with DMM...do you ever get steady reading?
Will moving the rod into the flame stabilize your reading? If it's not in a good ionized portion the reading can bounce. Look at your ground to the chassis and burner, microamps are very small and any poor/marginal connections will present a problem.

Re: Furnace is on, Fan blowing, intermittent heating.
So all you're willing to do is berate me and say you're not trolling. Great. and I can't even delete the thread and start over.

Re: Radiator paint smell never goes away
@pastorj I understand. Just had 10 of our 11 radiators repainted . They have been operating for about three weeks and still smell a lot when heated, but it is dissipating. In my case the paint is three part automotive epoxy applied with a spray gun. When they first heated up your eyes hurt a little. I would make sure you know what paint was used and look up the Material Data Sheet. Then call the manufacturer and see what they say the curing time is. Eventually they should stop out-gassing. With some paints I have heard there is a 60 day curing time. In the meantime encourage ventilation as much as possible.

Re: 110 V Tstats
Maybe a set of these? 120 volt, an A model for air temp, 7 day programmable. Get a pair, save the old ones & reinstall them when you move out.

Re: 2 Children Killed In Radiator Mishap In Bronx Apartment
This is why at every steam seminar I did I warned those who work on steam boilers never to close the boiler-room door. A popped safety can kill you.
Re: Can we turn off Main Water Valve while away from home for extended periods
A slightly more general answer: if, and only if, you have a low water cutoff or low pressure cutoff on the boiler, it may be safe to leave it running without the mains water on. However, be aware that if for some reason the pressure or water level does get low, the boiler will shut down, and the house will get cold and possibly freeze. You don't want that.
The only safe way I know of to turn off the mains water in a building but leave the hot water heat on is to have a freeze alarm on the building, which will alert someone that there is a problem -- and to have a reliable someone who will promptly turn up and fix the problem. Boilers turn off for reasons other than low water...
