the Heat Thief Out 



Of Your Steam Radiators 

 By Fitting Them With 

 Norwall Vacuum Valves 



DO you know why your radiators are cold winter 

 mornings when there is aKOod fire in the steam 

 heater below? Well, it is because air has gotten 

 into your radiators, killed the steam and stolen the 

 heat, although there is plenty in the boiler. 



Water boils at 212 degrees, but it would boil and 

 circulate steam through your radiators at a much 

 lower temperature if it were not that air exerts a 

 pressure equal to 15 pounds on every square inch 

 of water surface in your boiler. This pressure 

 must be lifted by steam and the air expelled 

 from the radiators be fore steam can circulate. 



If your steam radiators are fitted with 

 Norwall Automatic Air and Vacuum Valves, 

 this happens when you start the fire in the 

 boiler. When st earn begins to generate and the 

 air inside the apparatus is pushed into the 

 radiators, these Norwall Vacuum Valvesopen 

 automatically, letting the air pass out just like 

 ordinary vent valves. When the steam fills the 

 radiators and reaches the valves, they close. But 

 — when the steam in your radiators cools below 

 the temperature of 212 degrees, instead of open- 

 ing as ordinary vent valves do to admit air to 

 the radiators, the Norwall Vacuum Valves 

 remain tightly closed, and as the steam con- 

 denses, with no air to take its place, a Vacuum is 

 formed, which serves to draw the heat out of the 

 water and circulates it through the radiators in form

of vapor. Norwall Vacuum Valves are made entirely 

 of metal (illustration shown herewith) and ctn In- 

 attached to your steam radiators in place of the 

 ordinary valves. Their use will secure for your 

 home an even temperature — more and better heat — 

 and at less expense of time, labor and fuel. 



You don't have to touch the valves after they 

 are put on They are automatic and do their work 

 without adjustment or attention. They will do 

 their part if you do yours. 



And your part will be only to see that your 

 boiler is properly "fired. You won't need 

 to "fire-up" as often as heretofore, and you 

 can bank your fires on mild days and much 

 earlier at night, and still get heat enough 

 to give you thoroughly conmfortable rooms. 

 Norwall Valves will save their cost on any low 

 pressure heating apparatus and do a large part 

 of it the fir st season in red need fuel bills, and this 

 doesnottake intoaccountthe increased comfort 

 in your house, the lessened labor with your boiler 

 and more healthful heat conditions for you to 

 live in. Don't expose yourself and family to the 

 dangers of uneven temperature with resultant 

 chills, colds, rheumatism, and all their attendant ills. 

 Let us prove to you that Norwall Vacuum Valves on 

 your steam radiators will protect your comfort, your 

 health and your pocketbook. A postal card mailed at 

 once will bring you a lot o£ dollar-saving information on 

 heat apparatus.

Neglect* Your Fire Insurance 

 Rather Than Your Painting 



^-tt Your house may never burn — tire insurance is merely 

 ^ a wise provision against a remote contingency. 



j\ But with regard to paint, "it is a condition and not a 

 theory that confronts us.*' If we don't keep our property 

 well painted it will surely deteriorate, and this deterioration 

 can never be made good. A house kept in condition with 

 good paint is practically imperishable. "Good paint" is 

 paint based on pure linseed oil and OXIDE OF ZINC.
