Your gas burner has been carefully
inspected and tested at the factory;
however, different conditions at the
jobsite, including controls that have
been added at time of installation,
require careful testing and nal ad-
justment for satisfactory operation.
The Burner Test Report / Factory
Specication Sheet in each unit shows
the general data recorded during the
operation and safety tests at the fac-
tory. This data should be used as a
general guide; with nal data recorded
on the start-up form. Do not exceed
550°F ue temperature at the ID fan
inlet. Do not exceed 200°F supply air
temperature.
Introduction
This guideline describes the basic steps a technician
would take in starting an Eclipse Gas Burner 10:1 -
25:1 turndown and Powerame Gas Burner 3:1 - 10:1
turndown indirect red gas heat system on a YORK
Solution Air Handler for the rst time.
Each gas burner has been test run and inspected at
the factory. Adjustments to component settings are
typically not required. However, measurements of
system parameters should be taken and compared to the
measurements recorded on the “Burner Test Report” to
ensure safe and reliable operation. The “Burner Test
Report” is laminated to the inside of the burner control
door.
Identify the Unit Type
Two types of Indirect Fired gas burners are used on
YORK Solution Air Handlers: The Powerame series
and the Eclipse series. The Powerame series offers
a turndown (modulating ratio) of 3:1 or 10:1. The
Powerame is easily identiable by the motorized gas
valve with external linkage connecting the air dampers
on the burner air inlet.
The Eclipse series uses an air/gas ratio regulator with
no external linkage, and has a turndown range of 10:1
to 25:1 (sometimes greater). A visible external plastic
tube is used to transmit gas pressure from the burner to
the regulator. No external linkage is used.
Both burners utilize a combustion air blower. YORK
Solution Air Handlers also use an exhaust blower, called
an induced draft (ID) blower. This exhaust blower keeps
the combustion chamber at a slight negative pressure.
Verication of this negative pressure and other system
parameters is part of a proper start up procedure.
Indirect Fired Gas Heat Start Up
For your safety and satisfaction, this
product requires check, test and start-
up adjustment by a qualied HVAC
technician. Do not use for temporary
heat prior to start-up.
Review burner control literature, in-
cluding wiring, piping, cut sheets and
drawings before attempting to start
this unit.
All factory test start up burner speci-
cations are located on a laminated
“Factory Specication Sheet" located
on the inside of the control panel
door”.
