There have been a few more Granbys go out the door. The last one went south to Oregon. The dealer's install crew and techs had very favorable impressions of the furnace. When asked if they would be happy if more were sold, they replied "yes".

​Also, not necessarily directly involved in the HVAC industry although I am sure there are some applications for it, is the Hyndsight wireless camera. I first saw this at a trade show in Seattle and thought it was a quality product and liked the fact it was built in New Hampshire. The device was developed by a smart lady that like to row. Since a single skuller, like most all rowing vessels, is not looking ahead when being rowed things can happen. The least of which is a zigging path. She thought there should be a way to see ahead which was a little more higher tech than a tiny mirror on a hat. So with that this system was born. It had to withstand crummy weather and a possible dunking so that was designed into it. You can get more detail by viewing the products page under Hyndsight. Think what you could do with a camera placed where you cannot not see anything but be able to view that area from up to 1/3 of a mile. There are all kinds of things.

Well, the first couple of Granby furnaces have been installed. The first went in as a horizontal configuration and the dealer reported back that everything went well. That is always good news when one is introducing a new brand to the marketplace. Another was just installed in a home on Vashon Island, WA. The dealer, Williams Heating, also the heating oil provider on the island, reported in that it fired off extremely well and they were impressed with "the fit and finish". More good news for this distributor. There are plenty more in stock so come and get it!

Hello,
Welcome to my first blog.
​This first one is about an old topic regarding what size liner do you need for that new oil fired boiler or furnace or hot water heater. Nineteen years ago I was pretty excited to see there were situations based upon combustion efficiencies and chimney height where the metal chimney liner could actually be reduced from the size of the appliances actual breech. We all know that the safest practice is to match the size of the breech with the connector and the liner. A no  brainer. Well, there are times when reducing that size of a 7" or 6" breech to a 5" liner is real handy. Or how about a 5" breech to a 4" liner. Not only easier to pull but less expensive too!

​Back in 1997, the last time I purchased an NFPA 31, there were some combinations that would be applicable to installing  a four inch liner for something being fired up to 1.0 gph! How cool. That would work for almost everything that I sell. Guess what? The NFPA folks have changed the charts in Appendix E 2016. I don't know when or why. Apparently something didn't work out. The bottom line to this blog/sermon is to keep up on the codes. I have included the link address  if you want to take a look. They let you look at the book online for free. www.nfpa.org  (Sorry, the link vanished. IT is just wonderful ,he said sarcastically)
​
​I wonder why? I think everything that was ever known about combustion and condensing was old news in 1997 and subject not change.. So the subject of the blog changed from selling a whole bunch of 4" liners and making everyone's life easier and cheaper for the homeowner to keeping up of the freaking codes. However, if you do have a little .5 gph furnace @ 100 psi making rain in the chimney, check its afue, measure the connector and chimney height, then go to the APPENDIX E NFPA 31. You may be able to use a 4" liner and by golly, I just happen to have a bunch of them.

​Thanks for dropping by. I will try to come up with other tidbits from time to time for the good of the order.
​Regards, Spark
