Model 800
Light off the boiler and adjust the
Low-End Valve
as described above for models 500
– 600.
After the low fire settings are stable, ramp the boiler firing rate to 100% using the boiler control and bring system temperatures up to
130
o
F or to highest system design temperatures to minimize or eliminate condensate.
Models 1000
– 4000
Light off the boiler and adjust the
Low-End Valve
as described above for models 500
– 600.
Once the interface relay has switched to the
High-End Valve
, while maintaining the lowest possible water temperature, observe the
differential gas pressure when running with the
High-End Valve
. The differential gas pressure must not drop
below a minimum of 0.25”
W.C. Once the boiler has run for at least 5 minutes with dead cold water, there should be a maximum amount of condensate in the heat
exchanger. At this point adjust the combustion for CO
2
.
The boiler must continue to run with stable combustion without making any howling noise which usually happens from an overly rich
mixture. Once settings are complete at low fire, continue to run the machine for at least 5 more minutes and record the final low fire input
and the combustion data.
To ensure the coldest possible water temperatures for set up on multiple boiler systems, the low fire combustion should be established
on all boilers before setting any boiler high fire combustion rates.
In order to perform adjustments to the gas valve, the
Advantus
must be firing before proceeding.
