I asked a questions yesterday.. thank you for the quick response, but I made a typo.
The APW unit i am working with currently runs on Natural Gas. What gas pressure am I suppose to have for this Nat. Gas unit?
Typically Natural gas pressure is between 6 and 7 inches WC (water Column) some equipment will be lower or higher depending on consumption design. Of course a model plate on the equipment or data plate on the gas valve will list the proper WC. Some ovens or furnaces may be 3.5″WC and tankless water heaters can be as high as 11″WC. Be sure to check pressures on both sides of the regulator and/or gas valve to ensure the both are able to keep up with demand.
Your actual gas pressure will be approx. 2.5psi, the water colum pressure is 5 in w/c. pressures for all appliances are denoted in w/c and not psi. This can be adjusted at the gas valve of the appliance with a w/c guage connected to the manifold access tap. Hope this helps
