Unit Identification; Furnace Model Number; Burner Control Turndown; Furnace Serial Number - LG GEN2 Series Installation And Operation Manual

NOTE
Models PVF and PVG are indirect gas-fired heat
modules that will be referred to in this manual as a
furnace.
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
the carrier of any damage detected. The customer will
make notation of damage (or shortage of items) on the
delivery receipt and all copies of the bill of lading which is
countersigned by the delivering carrier. If damaged,
immediately contact your manufacturer's representative.
Any physical damage to the unit after acceptance is not
the responsibility of the manufacturer.
Unpacking
If unit is to be installed, tested and operated right away,
locate and remove all packing materials from the
furnace, including any protective coverings that may be
on the combustion air intake and on the furnace
exhaust. Follow Unpacking Instructions as found in the
unit-specific IOM.
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.

Unit Identification

It is necessary to know the unit model number, the
burner control turndown and the serial number. This
information is needed when ordering replacement parts
and is available on labels located on the unit.

Furnace Model Number

On the furnace access door or immediately next to the
door is a Mylar data label. See image below. Locate the
furnace model number at the top of the label and record
it here:

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.
INPUT BTU/HR
MINIMUM BTU/HR
150,000
Example:
75,000
The turndown ratio is 2:1 in this example.
