The heater requires water flow and positive pressure to
fire and operate properly. It must therefore be installed down-
stream of the discharge side of the filter pump. A typical
installation is plumbed as follows:
Maximum Equivalent Pipe Length
Natural Gas 1000 BTU/FT3 0.60
Specific Gravity @ 0.5 in. WC Pressure Drop
Propane Gas 2500 BTU/FT3 1.53
Specific Gravity @ 0.5 in. WC Pressure Drop
