7 INTRODUCTION This design complies with the current edition of the ANSI Z21.13 low-pressure boiler standard. Compliance under this standard implies that when the boiler underwent test, the gas manifold and control assembly pro vided on the boiler met safe lighting and other performance criteria.
8 HIGH AL TITUDE INST ALLA TIONS IN CANADA Acceptance of these models for use at altitudes above 2000 feet (600 m) is based on eld test of the individual installation by the provincial/state authority having jurisdiction.
9 THERMAL BALANCER Figure 4 shows the internal wiring of the thermal balancer . The device may be tested after disconnecting the four leads from their respective terminals on the unit. 1. Apply a test light to the yellow and red leads. • The lamp should light as the contact in this circuit is normally closed when the resistor is cool.
10 CAUTION Paddle must be trimmed at the dotted arc. It must not touch the pipe or have any restriction when installed. FIGURE 6. T o adjust the ow rate setting: 1. Remove the ow switch cover . 2. For higher ow rate - turn the range adjusting screw clockwise.
