Gas Burner Manual Supplement

CG15 / CG25 / CG50 Optional Modulation Control Systems

COMMERCIAL PRODUCTS

I. Introduction

The CG15, CG25, and CG50 gas burners are available

in three optional congurations that can be controlled

by the three most popular modulation control signals:

135 Ohm, 4 – 20 mA, or 2 – 10 VDC. All three of these

options use the Siemens SQM40 actuator for damper

control. The SQM40 accepts any of those signals, so the

difference between burners using any of those control

signals is internal wiring of the burner, the control signal

connections you make, and trim adjustments. When

operating with any of these signals, the burner’s ring

rate responds in a direct proportional control manner,

making them well suited for use with lead/lag or building

automation system controls. The standard burner

conguration for these modulation systems is with the

junction box (shown in Figure 1), but a panel enclosure

is optionally available.

Operator controls are the

same for all 3 signal types.
