Question Gas Wall Heater Regulators

I have an old vented gas double wall heater. I recently checked it and found that there are 3 regulators in the piping. Does anyone know what the regulator pressures are? It is a natural gas heater made by Mission, model .45 Sunair.

Hello bidyo. Welcome to my Gas Appliances topic & our Do-It-Yourself Web Site.

I have seen units installed with two regulators, but never three. This is not meant to imply there cannot be nor is it meant to say you do not see three.

Very possibly could be three regulators. Depending upon serveral possibilities. Most importantly is how the gas supply is delivered through the entire piping system of the building complex or individual home or structure, etc.

Common supply system is one regualtor outside the structure which reduces the delivery pressure form about 30 pounds of pressure to water colume pressure of between 7 to 10 inches of water colume pressure.

It is also possible the parts seen are not really regulators but individual componets as was common place during early made units, etc.

Best bet is to not suspect fault nor adjust anything with the unit. Nor with the heaters current installations setup until all the circumstances are throughly known.

Failure to do so may prove to be hazardous. Seek the advice of a qualified and licensed heating professional and than use the reply button to post back the final results.
