Scott, Are you using EC sprinklers? Unless there are some newer listings that I am not aware of, there are no listed EC's for combustible obstructed construction. I am also assuming wood construction in this case, is it? Regardless, standard spray sprinklers would probably be a better choice in this situation since they only require a 6' separation. EC's do not sound like they would be an advantage for your situation anyway.

The slope is only long enough to take one sprinkler at the peak, and another along the slopes toward each eave. I am in favor of voiding the 8 ft manufacturer spacing, rather than setting a sprinkler down in the small apex of the eave. scot deal excelsior engineering _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field) No virus found in this incoming message.
