Service Bulletin SB-1501: Replacing Your WM97 155 and ECO 155 Burner Gaskets

The WM97 155 and ECO 155 boilers manufactured before CP number 7004670, February 2014 were manufactured with a fiberglass burner gasket. The gasket glue seeped out of the gasket and electrically insulated the burner flame signal, so a weak flame signal would not allow the burner to run.  Some of these boilers would run for months, others failed soon after install.

It's been a while

The old macleodandgrant.com was growing a little long in the tooth. The design was a bit amateur, old links were going dead, entire sections were ignored and keeping the backend up to date was a job on its own. 

Throw in months of tinkering and frustration and about 6ft of snow (183cm I should say) and here we are now. Slim and trim, rebuilt to match how our customers actually used our old site and finally mobile friendly!

Going forward we'll fill this section with news and announcements from our suppliers, as well as the occasional goings-on at MacLeod & Grant. Welcome!
