The following notes apply to the tables accompanying Figures 1 - 4.
1. All models with flue dampers and/or above 400,000 BTU per hour
input employ a “spark” (IID) ignition system and requires 120 volt AC
electric supply.
2. * -Denotes minimum clearances to combustible material. Some
models may have different clearances. Check the label on the front of
the water heater to verify proper installation clearances.
3. Model number may have a suffix “N” for natural gas or “X”, “P” or “L”
for liquefied petroleum (LP) gases. Some models may have “A” as a
suffix or prefix. Check the rating plate on front of the water heater for
model number verification.
