Engine preheat hose to the boiler

[Pat roys]

Hi Greg,
Thanks so much for taking the time to get that info for me. I crawled under
the bird tonight and it looks like BB ran two 1" gates green stripe II hoses
from the left hand side of the engine and BB did install ball valve shut off's
on both of them. I can also see two hoses coming off the engine near the left upper area of the engine. These are the two hose that run to the aqua
hot for engine preheat. These are the two that I removed the bedroom floor
to axcess last summer when the aquahot preheat hose blew on vacation.
Then I installed ball valves and shut off that circuit. I will update you tommorrow on the size and type of hose coming ot of the aqua hot.

Thanks again
Pat
