Receiving
Upon receiving the product, check to ensure all
items are accounted for by referencing the delivery
receipt or packing list. Inspect each crate or carton
for shipping damage before accepting delivery. Alert

Storage
If unit must be stored after it is received, take steps to
protect furnace from damage, moisture, and extreme
temperatures. Verify that gas piping is plugged.
Burner Control Turndown
Burner turndown ratio is used in many places and must
be calculated. On the data label, locate the INPUT
BTU/HR (the largest number on the label) and also
the MINIMUM INPUT BTU/HR. Calculate the burner
turndown ratio and record it.
