A system bypass should be installed as shown in fig. 10 to prevent boiler circulation starvation when the system zones call for reduced flow.

This bypass may also be used with multiple boilers manifolded for reverse-return flow. The system bypass would be installed from boiler outlet to suction side of pump.

Standard Dura-Max models are factory equipped for Single Stage Firing only.

Dura-Max models may be factory equipped for Dual Stage Firing. The gas valve automatically steps gas input down from full input to approximately 50% total input. System conditions will then

determine if boiler will shut down or if unit will return smoothly to full input.

Dura-Max models may also be equipped with modulation which automatically adjusts the boiler output to match the system heat loss and variations of system water flow. Minimum firing rate is 50%.

INSTALLATION AS BOILER REPLACEMENT

Installation as boiler replacement on an old system with large water volume may result in condensation within the boiler on cold starts. This condensing of water vapor in the combustion area can be prevented if a portion of the system water flow is diverted past the boiler to cause an increase in boiler temperature rise.

DB INSTALLATION

INSTALL IN ACCORDANCE WITH

ALL LOCAL CODES.

WHEN BLOW DOWN VALVE IS

REQUIRED, INSTALL IN PLACE OF

THE DRAIN VALVE SHOWN.
