Compatibility of Honeywell VS8187A 1344 and Honeywell VS8187A 1369 gas valves
Our house has an old "snowman" heating system installed in 1925. It is operated with a Honeywell VS8187A 1344 gas valve. The system has worked very well for us for 20+ years. However, a few days ago, we found the temperature in the house at 62 degrees, although the thermostat was set to 67 degrees. Our heating person tested whether the thermostat or the gas valve was at fault and determined it was the valve. (I should add that about three years ago a similar situation occurred and we had to tap the gas valve with a wrench to get the furnace on while waiting for a new thermostat to be installed; once that was done, the system worked until the current problem arose.) It now appears that we need to buy a new gas valve for the old snowman. I've looked online (mostly ebay) and have found a number of used or "new/old stock" Honeywell VS8187A gas valves, but the numbers following the VS8187A vary. For example, one such valve is listed as VS8187A 1336 and another as VS8187A 1369. Could anyone tell me whether our current VS8187A 1344 can be replaced by either of the valves for sale on ebay? We'd really like to avoid having to deal with asbestos removal and the installation of a new furnace at this time. And we really like our very quiet and effective snowman...Thanks!
