IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
It is normal for replaces fabricated of steel to
give off some expansion and/or contraction noises
during the start up or cool down cycle. Similar
noises are found with your furnace heat exchanger
or car engine.
IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
It is not unusual for gas replaces to give off some
odor the rst time it is burned. This is due to the
manufacturing process.
