Natural Gas To Propane Conversion
DanD posted a topic in Non-Outdoors Open DiscussionI could use some help from any of the HVAC people that may be on board? I'm converting a NG pizza oven to LP. I have the replacement nozzles and the conversion kit for the Robertshaw gas valve. Replacing the hard parts look relatively easy. My question is what should the inlet and manifold pressures be? The spec plate on the oven, only gives NG pressures; as in 7" WC inlet and 3.5" manifold. From my research the inlet pressure for propane seems to be 11" - 13" WC; but getting mixed info on manifold pressure? Some techs are telling me half the inlet pressure (like NG) and others are saying 8"-10". One last question, do you check pressures static or with the burners fired? I assume fired but every time I assume something; I turn out to be the ass in the equation. LOL Thanks. Dan.
