air supply to Carlin EZ-gas

Just installed Carlin EZ-gas to Weil Malain. Unit has new design with cover. What size air supply line from outside air is required? Looks like adapter on cover is for 3 inch inlet but that seems too small to me. No info provided from Carlin. Who has installed these and what size duct did you use?

    You don't necessarily need to use a duct

    with the acoustic cover. They give you a screen to use on the intake opening if you don't install a duct.



    What is your input rate?

    Cover has 3 inch connector. Is 2 in or 3 inch pvc vented from outside adequate for the EZ-gas?

    Depends

    on the gas input rate. This affects how much air is needed.



    Which model W-M boiler do you have- SGO or WGO or WTGO-(some number)?
