CHAPTER 1
Introduction
Q series burners are completely assembled, wired, and tested at the factory.
The operator must be familiar with the individual functioning of all controls to understand the operations and
procedures described in this manual.
1.1 — Description
Q-series full modulation units are forced-draft, direct-spark ignited, linkage-less burners controlled by an LMV37
programmer. They include safeguard functionality to insure the burner always returns to the ignition light-off
position for startup.
The Q-series modulating burners provide 550 to 2,500 MBTU/hr (~13 to 60 boiler horse power) against
furnace pressures of 0.75" w.c. or less (refer to burner specifications, page v ). The Q6 has a 6" diameter firing
head and can fire up to 1,500 MBTU/hr (~36 boiler horse power). The Q8 has an 8" diameter firing head and
can fire up to 2,500 MBTU/hr (~60 boiler horse power). A field-installed air inlet orifice plate is required on Q6
burners firing below 1500 MBTU/hr and Q8 burners firing below 2500 MBTU/hr. See page viii for orifice plate
part numbers.
Q series burners are designed for automatic unattended operation except for periodic inspection and
maintenance. The control panel components require little attention except for occasional cleaning.
Only factory authorized burner service personnel should start up, adjust, or service this equipment.
