Pipe sizerunning to the unit depends on:• Length of pipe.• Number of fittings.• Type of gas.• Maximum input requirement of allgas appliances in the residence.Insure that:• Flexible gas pipe is used (if acceptable by local codes). The gas valve and blower cannot supportthe weight of piping, leading to blower vibration and damaged components. If rigid piping is used,ensure that the valve supports NO WEIGHT• You plan the installation so that the piping does not interfere with the vent pipe, or the removal ofthe valve, burner, and serviceable components.• The Boiler shall be installed such that the gas ignition system components are protected fromwater (dripping, spraying, rain etc.) during installation and servicing.• The gas piping is large enough for all the appliances in the home. No appreciable drop in line ormanifold pressure should occur when any unit (or combination of units) lights or runs.• Always use a pipe-threading compound that is resistant to propane (LP) gas solvent action. Usesparingly to all male threads, starting at two threads from the end. Over doping or applying dopeto the female end, can result in a blocked gas line.• DO NOT TIGHTEN FITTINGS WITHOUT SUPPORTING THE GAS VALVE as damage to thevalve or motor can occur.• Install a manual “equipment Shut-Off Valve” as shown. Valve must be listed by a nationallyrecognized testing lab.5.2 Testing and settingsWhen running, the line pressuresupplying the unit must be 4-9inches w.c. for Natural gasinstallations and 9-12” forPropane installations. Ensurethat the regulator is capable of maintainingthis pressure under all operationalconditions.The gas valve is equipped with two bleedports; one is for the Manifold pressure, andthe other is for the Line pressure. Linepressure should be maintained at 4-9”w.c forNatural Gas and 9-12”w.c for Propane whilerunning at maximum rate.The input Screw “MUST NEVER BEADJUSTED” without verifying propercombustion with a calibrated combustion analyzer.WarningIf line pressure exceeds ½ PSI (14 inches w.c.)completely disconnect line to gas valve. Thisexcessive pressure can damage valve,causing a leak resulting in fire or explosion.It is highly recommended to useflexible gas pipe, the gas valve andblower cannot support the weight ofpiping.
