In mild winter weather sufficient heatis usually secured with vacuum instead of pressure in boiler, andin many cases it has been unnecessary to create steam pressureall winter. As vent valves are not required on radiators, air inthe rooms is not fouled by odors from boiler, piping and radia-tion; and there are no leaky or hissing radiators. The Vacu-Vapor Equipment always does its work properlyand is absolutely fool-proof. sidling the RELIABLE Vacu-Vapor Heating Equipment JC^I S T E A M M A IK^Ji VACU-GRADUATEPACKLESS VALVE.
