This replacement was imposed on me since when the plumber replaced an 18-year old leaking water heater, he replaced it with a water heater that _probably_ requires a venter stronger than the existing TJERNLUND HSUL-1. I say "probably", because the plumber himself admits that he doesn't know why the water heater keeps shutting off by the safety thermocouple switchs next to the "draft hood".
So, is it true that all new water heaters require more powerful venters? (one hint that I received was that the vent in the new heater is WIDER the vent in the old heater - 4" diameter vs. 3").
If so (which means I have no choice but shell out extra $$$ to buy a new venter), could someone recommend a QUIET sidewall venter? What about an EXTERNAL venter that can withstand extreme weather (New England winters...)
If not, could someone please suggest brands/models that can work with the TJERNLUND HSUL-1 (http://www.tjernlund.com/gassidewall.htm ) ?
