If the confined space is within a building of tight construction, air for combustion and ventilation must be obtained from outdoors.
12 W ater supply systems may , because of such events as high line pressure, frequent cut-of fs, the ef fects of water hammer among others, have installed devices such as pressure reducing valves, check valves, back flow preventers, etc. to control these types of problems.
13 Figure 10 shows the typical attachment of the water piping to the water heater . The water heater is equipped with 3/4 inch NPT water connections. NOTE: If using copper tubing, solder tubing to an adapter before att aching the adapter to the water heater connections.
14 GAS PIPING Make sure the gas supplied is the same type listed on the model rating plate. The inlet gas pressure must not exceed 14 inch water column (3.5 kPa) for natural and propane gas (L.P .). The minimum inlet gas pressure shown on the rating plate is that which will permit firing at rated input.

24 B. Deburring Use a knife, plastic pipe deburring tool, or file to remove burrs from the end of small diameter pipe. Be sure to remove all burrs from around the inside as well as the outside of the pipe. A slight chamfer (bevel) of about 10°-15° should be added to the end to permit easier insertion of the pipe into the end of the fitting.
